Westgold Managing Director and CEO Wayne Bramwell commented:
"Q2, FY25 was the first full quarter of Westgold stewardship
of the Southern Goldfields assets. Outputs continue to lift with a
record group gold production of 80,886oz - increasing net mine cash
flows to $45M and funding the
Company's operational and growth capital requirements. Westgold
also drew down $50M from the
corporate facility during the period to balance the working capital
requirements of our much larger business.
The FY25 strategy is to systematically reconfigure the larger
portfolio to generate higher levels of free cashflow with capital
investment in critical mine infrastructure at Beta Hunt and
Bluebird-South Junction, and resource development drilling key to
achieving this.
In the Southern Goldfields we have rapidly demonstrated the
ability to lift mine outputs. We are investing for the next decade
of operations at Beta Hunt with the key enablers to higher mine
productivity including a clean mine water supply, upgrades to
underground pumping, power, ventilation and facilities for our
workforce. All of these projects are underway and on completion
will set this mine up to consistently deliver >2Mtpa run rates
during 2025.
In the Murchison, we are steadily expanding the
Bluebird-South Junction mine to lift outputs to 1-1.5Mtpa run rates
in 2025, ultimately sustaining the Bluebird mill from a single
source. A change in ground support methodology to support
the expansion and transition to a larger transverse open stoping
mining method slowed the progress of this ramp up in Q2, and with
those changes now implemented, Bluebird-South Junction mine output
is increasing again.
Seventeen drill rigs are operational today. At South Junction, intersections such as
68.00m at 5.48g/t Au and
45.00m at 4.18g/t Au highlight the
quality and thickness of the mineral endowment. At the Fletcher
Zone, five rigs are operational, with highly encouraging results
including 6.6m at 41.84g/t and
24.6m at 6.9g/t Au building our
confidence in a third mining front.
Our strategic asset review commenced with the Fortnum scoping
study defining a pathway to a higher margin, expanded 1.5Mtpa
facility with a 10-year integrated mine plan. At Meekatharra we
finalised an ore purchase agreement with a Murchison explorer that
unlocks value for all shareholders and will provide a new softer
feed source to our Bluebird mill in FY26.
Strong treasury management is key to delivering our strategy
and providing returns to our shareholders. During the quarter
Westgold expanded our corporate facility to $300M without mandatory hedging to support mine
and process plant expansion plans as this investment will reduce
operating cost and enhance future cashflows.
Building a simpler, yet larger scale and more profitable
business requires investment and time.
Six months on post-merger, Westgold now has the portfolio
that can deliver increased levels of free cash flow. Our capital
investments are focussed on higher mine productivity and lowering
our all in sustaining costs with the Group's Q4, FY25 exit run rate
the measure of our success."
Executive Summary
Cash Position at 31 December
2024
Q2, FY25 was the first full quarter of Westgold stewardship of
the Southern Goldfield assets.
Westgold closed the quarter with cash, bullion and liquid
investments of $152M (see
Figure 1). This result was driven by record group gold
production of 80,886oz, increasing net mine cash flows of
$45M and funding the Company's
operational and growth capital requirements.
Westgold also draw down $50M from
the corporate facility during the period to balance the working
capital requirements of now, a much larger business.

Notes
- Merger costs of $13M relating to
Karora Resources Inc's North American advisor costs finalised in
Q2.
- Dividend payment relates to payment of FY24 Final Dividend
(declared 1.25 cent per share fully
franked).
- Working capital movement of $29M
reflects the timing of creditor payments.
- The draw down of $50M from the
corporate facility provides prudent overall treasury management of
a larger business.
Group Production Highlights – Q2 FY25
Westgold achieved its highest quarterly gold production in Q2
FY25, producing 80,886 ounces and generating $45M in net mine cashflow.
This included 46,461 ounces from the Murchison and 34,425 ounces
from the Southern Goldfields. Notwithstanding the
quarter-on-quarter improvement in ounces produced, the ramp up at
the Bluebird-South Junction and Beta Hunt underground mines was
slower than planned.
All-In Sustaining Cost (AISC) for the quarter was
$2,703/oz (Q1 FY25
$2,422/oz). The elevated AISC $/oz in
Q2 FY25 was due to lower than anticipated production from
Bluebird-South Junction and Beta Hunt combined with the impact of
absorbing a full quarter of Southern Goldfields operating
costs.
Capital growth projects continued to advance across the Group in
line with the current strategy to ramp up production in H2
FY25.
The Company sold 86,879oz of gold for the quarter
achieving a record price of $4,066/oz, generating $353M in revenue. With Westgold free of any
fixed forward sales contracts, the Company continues to offer
shareholders full exposure to record spot gold prices.
Westgold's operations generated $110M of mine operating cashflows with the
achieved gold price $1,363/oz over
AISC. AISC for Q2 FY25 of $219M (Q1 FY25 of $187M) including $32M in additional costs from the Southern
Goldfields being under Westgold's control for the first full
quarter.
As illustrated in Figure 3 the monthly AISC since post-merger
(August 2024) has been relatively
consistent.
Capital expenditure during Q2 FY25 of $56M (Q1 FY25 $58M) includes $29M
investment in growth projects (Bluebird-South Junction and the
Great Fingall development), $27M
upgrading processing facilities, infrastructure and equipment
across the sites.
Investment in exploration and resource development of
$9M (Q1 FY25 $14M) for the quarter was focussed on
Bluebird-South Junction and Starlight in the Murchison, and the
Fletcher Zone, Larkin Zone and Two
Boys underground in the Southern Goldfields.
The net mine cash inflow for Q2 FY25 was $45M (refer Table 1 under Group
Performance Metrics).
Environmental, Social and Governance (ESG)
People
People are a key enabler of operational productivity. Westgold
is committed to investing in building organisation capability and
lowering workforce turnover. Westgold's continued focus on
diversity and inclusion has been recognised at the AMEC Awards
2024, with Westgold celebrated as finalists for the Diversity and
Inclusion Award. Respect in the Workplace training was rolled out
to the business and a Respect Hotline was established as another
avenue for the workforce to raise workplace concerns.
At the end of the quarter, Westgold employed 2,100 employees and
contractors.
Safety and Sustainability
Westgold has maintained a strong focus on safety, resulting in
continued positive trends across key performance indicators this
quarter. The Total Recordable Injury Frequency Rate (TRIFR)
decreased to 6.85 injuries per million hours worked, representing a
7.09% improvement quarter-on-quarter. The business recorded zero
(0) Lost Time Injuries, resulting in a 3.52% decrease in the Lost
Time Injury Frequency Rate (LTIFR) to 0.98. The High Potential
Incident Rate (HiPR) increased from 5.18 to 6.09.
During this quarter, zero (0) Significant Environmental
Incidents were recorded.
Group Performance Metrics
Westgold's quarterly physical and financial outputs for Q2
FY25 are summarised below.
The Group operates across the Murchison and Southern Goldfields
regions of Western Australia with
the Murchison Operations incorporating four underground mines
(Bluebird-South Junction, Starlight, Big Bell, and Fender) and
three processing hubs (Fortnum, Tuckabianna and Bluebird).
Westgold's merger with Karora Resources Inc completed on
1 August 2024. These assets are
grouped and reported as Westgold's Southern Goldfields operations –
incorporating the Beta Hunt and Two Boys underground mines and two
processing hubs (Higginsville and Lakewood).

Q2 FY25 Group Performance Overview
Westgold processed 1,342,005t (Q1 FY25 – 1,289,561t) of
ore in total at an average grade of 2.1g/t Au (Q1 FY25 –
2.1g/t Au), producing 80,886oz of gold (Q1 FY25 – 77,369oz).
Group AISC in Q2 FY25 was $219M (Q1 FY25 - $187M).
The $32M increase reflects the
enlarged Westgold post-merger accounting for three months' worth of
production at the Southern Goldfields in comparison to two months
in Q1 FY25.
MURCHISON
The Murchison operations produced 46,461oz of gold (Q1
FY25 – 52,889oz), largely as a result of lower production from the
Bluebird-South Junction mine and reduced access to low grade
stockpiles.
Total AISC of $119M was in
line with the prior quarter (Q1 AISC - $121M). Total AISC continues to trend down
against historical average quarterly AISC, demonstrating the
effectiveness of Westgold's cost optimisation and focus on
profitability. Mining costs in the Murchison operations were
$1,549/oz (Q1 FY25 $1,074/oz) coinciding with additional costs to
re-establish access to remnant mining areas at Big Bell being
offset by lower sustaining capital requirements. In addition, a
revision to ground support requirements in the South Junction area of the Bluebird-South
Junction mine, slowed production from South Junction and resulted in increased
ground support costs for this quarter.
Total Capital expenditure of $41M,
included Growth Capital ($26M) and
Plant and Equipment ($15M) across the
Murchison operations. Growth Capital related to the Great Fingall
development and expansions to the Bluebird-South Junction and
Starlight mines.
Plant and Equipment capital includes investment related to
processing facilities ($6M),
Bluebird-South Junction primary ventilation fans ($3M) and Bluebird paste plant ($2M) during the quarter.
SOUTHERN GOLDFIELDS
Q2 represents the first full quarter of operation under
Westgold's ownership. The Southern Goldfields production continued
to increase, delivering 34,425oz of gold (Q1 FY25 –
24,480oz).
The additional month's operation resulted in increased total
AISC in the Southern Operations quarter on quarter (Q2 AISC -
$100M vs Q1 ASIC -
$65M). On a per ounce basis, AISC was
higher at $2,903/oz (Q1 AISC –
$2,696/oz) as a result of production
being impacted due to a bearing failure on a primary ventilation
fan and a burst rising main (impacting pumping) at Beta Hunt.
Produced ounces were under budget due to lower grades seen in
development tonnage and smaller content of coarse gold from the A
Zone lode at Beta Hunt. Grade reconciliation was an issue with the
inherited resource model now being populated with a backlog of
drill data left from the previous operators and new drill data from
the latest Westgold drilling.
Total Capital Expenditure of $15M, included Growth Capital ($3M) and Plant and Equipment ($12M) across the Southern Goldfields operations
relating to Beta Hunt mine, processing facilities and underground
equipment.

Operations Summary
Murchison
- Bluebird-South Junction Underground Mine
(Meekatharra)
The production ramp-up at Bluebird-South
Junction ended Q1 in line with planned throughput rates and poised
to commence substantial stoping operations at South Junction. In October updated
geotechnical modelling highlighted the need to enhance ground
support for both existing and new development drives in
South Junction to support the
expansion and transition to a larger transverse open stoping mining
method.
While this required additional resources and
temporarily slowed production ramp-up during Q2 FY25, the enhanced
ground support management plan – which is not dissimilar to ground
support used in other Westgold mines – is not expected to
materially impact steady state mining rates or anticipated mining
costs going forward.
By December, full access was restored to the
South Junction mining fronts and
production momentum regained. The planned 1.2Mtpa run rate is now
expected to be achieved in late Q4.
In conjunction with the expansion in mining
rates, project works remain on track for underground HV electrical
upgrades, primary ventilation upgrades and paste fill
infrastructure. The completion of these projects will ensure
sustained production growth from South
Junction.
- Bluebird Mill (Meekatharra)
Lower than anticipated production at
Bluebird-South Junction and lower production at Fender in November
(see section below for details) constrained ore supply to the
Bluebird mill. As a result, the Bluebird mill operated at reduced
capacity during Q2.
However, this situation created a valuable
opportunity to address legacy maintenance issues. These items
including screening upgrade, tankage repairs and reline, elution
circuit upgrade and structural repairs where completed, ensuring
enhanced availability and reliability as Bluebird-South Junction
progresses toward its ramp-up to 1.2Mtpa.
- Fender Underground Mine (Cue)
Production at Fender had a strong start to the
quarter, achieving record production in October. A severe, yet
localised rainfall event in November temporarily impacted critical
underground dewatering infrastructure. Production returned to
steady levels in December, with substantial works completed to
enhance surface flood protection.
Looking ahead to Q3, the focus will be advancing
the Fender decline to access the next level in the sequence,
positioning the mine for sustained steady state production.
- Big Bell Underground Mine (Cue)
Production from the cave increased compared to
the previous quarter due to commencement of remnant cave mining,
averaging 110kt per month, with a record production month achieved
in December. A scoping study was completed early in Q2 on mining
remnant areas of the cave, with the study identifying low-cost
production that could be mined from remnant drawpoints between the
320 and 585 levels.
Efforts to re-establish access to the remnant
drawpoints commenced in the upper levels of the cave with some
remnants being mined during the quarter and setting the stage to
commence increased levels of bogging activity in Q3.
The ability to mine remnants in the upper areas
of the cave has insured continued ore availability when combined
with the ore from the cave bottom. This has allowed Westgold to
defer the development of the long hole open stoping mine in the Big
Bell Deeps and prioritise the Bluebird-South Junction and Beta Hunt
mine expansions.
This deferral is expected to reduce capital
expenditure in FY25 by up to $20M.
- Great Fingall Underground Mine (Cue)
The development of the Great Fingall project
made strong progress during the quarter, with development advancing
as planned.
The establishment of the Life-of-Mine (LOM)
infrastructure is progressing smoothly, with preparations underway
for the installation of an upgraded primary ventilation fan in
early Q3. This upgrade will support the continued growth of the
mine and ensure adequate ventilation to meet production
demands.
Furthermore, the upgrade to the dewatering
infrastructure is on track, with a new rising main being drilled to
support the installation of a new pump station on the 1660
level.
Early Mining Opportunity
Over the last year, Westgold investigated the possibility
of mining flat lying structures in the vicinity of the existing
Great Fingall Open Pit, collectively termed the Fingall Flats. A
drilling program of the Fingall Flats, completed in Q4 FY24,
provided confidence that the grade and distribution of gold
warranted further development of a mine plan which would enable
extraction.
Westgold has completed substantial work derisking the mining of
this ore which daylights into the exiting pit walls and contacts
historical mine development. Higher than anticipated complexity of
the derisking work delayed production expectations from H1 into H2
FY25.
With this work now completed, Westgold have built a robust mine
plan that sees the development of bulk stopes to recover Great
Fingall Flats ore, with mining to commence in late-Q3 FY25
following the completion of ore drives during Q2.
These early, bulk stopes are expected to substantially reduce
execution risk and increase recoverability of the ore whilst
optimising operating costs. It is expected that over 100kt of ore
can be mined from this source at a mined grade of ~1.3-1.7g/t and
rate of approximate 20kt/month as a precursor to accessing the
higher grade, virgin stopes from Q4 FY25.
- Tuckabianna Processing Hub (Cue)
Big Bell underground ore was the primary source
of ore feed to the Tuckabianna processing hub, with throughput
remaining steady at 107kt per month and recovery at 87%. The plant
experienced minimal unplanned downtime during the quarter, with the
planned mill reline completed in November.
Construction of the Tuckabianna West in-pit
tailings storage facility is progressing well, with planned
completion set for early Q3. Earthworks, piping, and power line
installation have been successfully completed according to plan.
Once completed, the facility will secure 8 years of tailings
storage capacity.
- Starlight Underground Mine (Fortnum)
Production and grade from Starlight continue to
exceed expectations, with the 1095 level development yielding
high-grade ore, significantly boosting Starlight's production
output for the quarter. Production continues in Nightfall on the
1140 and 1160 levels, as well as in Starlight on the 865 level.
Progress on the ventilation upgrade is moving
forward smoothly, with the development of a new vent portal
completed during the quarter. The planned upgrade of primary fans
in Q3 will further support the mine's expansion into the Nightfall
area.
- Fortnum Processing Hub (Fortnum)
Starlight underground material contributed 90% of the ore
feed to the Fortnum processing hub, with the remaining 10% sourced
from low-grade stockpiles. In November, the processing plant
achieved its highest throughput since May
2020, processing 73kt of ore. Planned maintenance during the
quarter included a full reline of both the Ball and SAG mills.
Additionally, the completion of the TSF2 Cell 2 lift to 518mRL in
November provided increased tailings storage capacity.
Southern Goldfields
- Beta Hunt Underground Mine (Kambalda)
Beta Hunt had a strong start to the quarter,
achieving a record in October with ore production of 161kt (1.9Mt
annualised rate), and the fifth highest monthly mined ounces on
record, totalling 11.2koz. This strong performance was supported by
operational improvements, including enhanced manning levels and
surface remoting over shift changes, highlighting Beta Hunt's
potential to achieve a 2Mtpa production rate.
In November and December, production was
impacted by ventilation restrictions due to a bearing failure on
the primary fan and a burst rising main. These issues hindered
production output and impeded capital development progress,
delaying access to additional production fronts in the A-Zone and
Western Flanks.
Westgold is in the process of updating resource
models and establishing 24-hour geology support at Beta Hunt, after
an internal study identified these as key drivers for grade
underperformance against plan. Despite substantial drilling having
been completed across Western Flanks and A-zone, the inherited Beta
Hunt resource models excluded substantial infill definition data,
causing poor grade reconciliation.
This data is being incorporated into current
resource models as a priority, with the work expected to be
completed in January 2025. The lack
of 24-hour geology coverage underground has been identified as the
primary driver a poor spatial compliance at Beta Hunt to plan,
resulting in increased ore dilution.
Another key driver for lower than planned Beta
Hunt grade was the lack of anticipated coarse gold presentation in
ore, which until as recently as last year, was predictably found in
accordance with Karora's models.
Despite these challenges, Beta Hunt continues to
demonstrate strong production potential. The focus moving into Q3
will be on addressing key operational challenges, including
resolving ventilation constraints and upgrading underground water
supply and dewatering infrastructure, ensuring Beta Hunt is set up
for growth and sustained efficiency.
- Lakewood Processing Hub (Kalgoorlie)
Beta Hunt underground material served as the
primary ore feed for the 1.2Mtpa Lakewood
Mill at Kalgoorlie, continuing to support the mill's
operations effectively.
Lakewood processing achieved strong throughput
for the quarter, meeting forecasted throughput levels despite a
setback caused by the premature failure of a ball mill discharge
grate. The issue was promptly addressed, and sustained high
throughput helped mitigate the impact of this downtime.
Construction of a new Tailings Facility cell was
successfully completed during the quarter, further enhancing the
site's tailings management capacity.
- Two Boys Underground Mine (Higginsville)
Production from the Two Boys underground mine
remains steady, demonstrating consistent performance. The
development of the ML70 diamond drill drive was successfully
completed during the quarter, and grade control drilling has now
commenced.
Fourteen holes have been completed as part of
Westgold's first drilling program, with assays from three of these
holes indicating a potential extension to the life of mine. This
positive result enhances the outlook for continued production and
further resource potential.
- Higginsville Processing Hub (Higginsville)
The 1.6Mtpa Higginsville processing plant
currently relies on Two Boys underground and surplus Beta Hunt
underground ore as its primary ore feed sources. During the
quarter, the mill head grade was slightly below forecast due to
increased low grade stockpile blending with lower ore supply from
both mines.
The Chalice return water system experienced
multiple pump failures, leading to a temporary reduction in plant
availability. In response, significant resources have been
allocated to improving the reliability of the return water system
to minimise future disruptions and optimise plant performance.
The TSF 2-4 Stage 4 lift is progressing as
planned and remains on track for completion in early Q3. Looking
ahead, the primary focus will be on enhancing the reliability of
the Chalice return water system and completing the TSF lift to
further support ongoing plant efficiency.
Exploration and Resource Development
Westgold continues to invest in exploration and resource
development across the Company's highly prospective tenement
portfolio. Key activities have been summarised in this section.
Murchison
RESOURCE DEVELOPMENT ACTIVITIES
Starlight (Fortnum)
The Nightfall lode has driven the recent period of elevated
performance at Fortnum, and thus the site has continued to focus
resources to this orebody. Drilling has continued to define this
high-grade area ahead of the mining front to ensure maximum
extraction of value for the operation. Better results from resource
definition work returned this quarter include:
- 35.96m at 5.51 g/t Au
from 161m in NF1120RD22;
- 5.65m at 360.84 g/t Au from
27m and 10.79m at 66.79 g/t Au from 74m in NF1120RD28; and
- 10.85m at 10.52 g/t Au from
209m in NF1120RD29.
During the quarter, a significant Mineral Resource Estimate
upgrade was released for Starlight (refer ASX 13 November 2024
- Starlight Mineral Resource Grows by 91%) which now stands at
12.9Mt at 2.7g/t Au for 1.13Moz of gold - a 91% increase on the
June 2024 Starlight Mineral Resource
Estimate. The expanded Mineral Resource Estimate is the product of
concerted investment in resource definition drilling over a 2-year
period and features a newly defined Open Pit Mineral Resource
Estimate of 4.2Mt at 2.2g/t au for 290koz.
The updated Mineral Resources Estimate subsequently underpinned
a Scoping Study detailing an expanded Fortnum Gold Operation
featuring an increased milling rate of 1.5Mtpa over a ten-year life
(refer ASX 17 December 2024 - Fortnum
Expansion Study).
Bluebird-South Junction (Meekatharra)
Westgold's significant and ongoing investment in surface and
underground drilling at Bluebird-South Junction was rewarded this
quarter with the announcement of a 65% increase in Measured and
Indicated Resources on the June 2024
Mineral Resource Estimate, contributing to a total Bluebird-South
Junction Mineral Resource Estimate of 1.4Moz (refer ASX
18 November 2024 - Bluebird-South
Junction Mineral Resource Grows to 1.4Moz). This figure represents
a 240% growth in the Mineral Resource Estimate post mining
depletion over an 18-month period.
The Mineral Resource Estimate increase led to a doubling of the
Ore Reserve for the project, which now stands at 7.2Mt at 2.5g/t Au
for 573koz (refer ASX 4 December 2024
- Westgold Doubles Bluebird-South Junction Ore Reserve).
Westgold intends to maintain this trajectory of growth at
Bluebird-South Junction, with drilling continuing on both surface
and underground with four rigs active during the quarter. Better
results returned from this work include the following spectacular
infill intersections at South Junction:
- 68.00m at 5.48g/t Au from
150m in 24BLDD171;
- 67.64m at 2.83g/t Au from
163m in 24BLDD170;
- 45.00m at 4.18g/t Au from
222m in 24BLDD171;
- 49.26m at 3.66g/t Au from
206m in 24BLDD083A;
- 14.70m at 10.11g/t Au from
168m in 24BLDD079;
- 43.00m at 3.50g/t Au from
217m in 24BLDD151; and
- 20.90m at 7.37g/t Au from
204m in 24BLDD152.
Big Bell (Cue)
Resource drilling at Big Bell remains ongoing, progressively
providing improved definition within the broader mine plan. Better
results returned this quarter include:
- 21.15m at 3.11g/t Au from
188m in 24BBDD0014;
- 18.62m at 2.16g/t Au from
202m in 24BBDD0018; and
- 21.18m at 3.48g/t Au from
217m in 24BBDD0019A.
Fender (Cue)
Some broader-scale intervals were encountered from drilling
conducted this quarter, which will provide incremental upside
against the current mine plan. Better results from this work
include:
- 13.72m at 3.25g/t Au
109m in 24FNDD0042;
- 9.10m at 2.61g/t Au
92m in 24FNDD0043; and
- 5.55m at 7.26g/t Au
91m in 24FNDD0048.
Great Fingall (Cue)
Diamond drilling recommenced at Great Fingall this quarter
from underground, with activities targeting first ore horizons
within both the Great Fingall and Golden Crown Reefs, resource
extensions, exploration targets at Great Fingall and grade control
activities within the Great Fingall Flats subsequent to ore
development activities being completed on the 1850 Level.
Grade control modelling to allow stope design on the 1850 is
progressing, and immediately following this geotechnical modelling
to understand stope stability and pit wall exposures will be
completed which will allow production in this area to commence
early Q3 FY25.
Some of the better results returned by drilling at Great Fingall
this quarter include:
- 3.98m at 37.10g/t Au from
309m in 24GFDD079;
- 4.4m at 8.81g/t Au from
323m in 24GFDD082; and
- 5.31m at 4.33g/t Au from
8m in 24GFDD130.
Progress was also made this quarter in terms of evaluating
large-scale open pit opportunities in the Cuddingwarra area. A
district-scale resource model amalgamation exercise was completed
by specialist mining consultancy. Evaluation works on this model
are scheduled to commence in coming quarter.
GREENFIELDS ACTIVITIES
Greenfields activities in the Murchison included 5,787m of reverse circulation (RC) drilling
testing the Mt View target at Day Dawn (Cue), the Champion target
at Nannine (Meekatharra) and the Five Ways targets at Peak Hill
(Fortnum).
The Mt View program was testing the historic Mt View reef
system located proximal to the Great Fingall Reef which is
currently under development by the Company. Assay results returned
some encouragement including 2.00m
@ 47.93g/t Au in hole 24GCRC04, 3.00m @ 2.34g/t Au in hole 24GCRC039 and
3.00m @ 1.85g/t Au in hole
24GCRC034. Further assessment of the results and potential
follow-up planning is underway.
The Champion RC drilling program was testing the historic
Champion Reef system which is the northern extension of the
Caledonian system at Nannine.
This program successfully intersected the reef in all holes with
some encouraging results including 8.00m @ 5.05g/t Au in hole 24NNRC001,
3.00m @ 3.53g/t Au in hole
24NNRC008 and 4.00m @ 2.74g/t
Au in hole 24NNRC013.
The Peak Hill RC program only commenced during December and no
results have been returned as yet.
In addition to the new RC drilling programs, the assay results
of the early stage aircore (AC) drilling program completed at
Labouchere (Fortnum) last quarter were finalised with some
significant encouragement including 3.00m @ 6.07g/t Au in hole 24LBAC044,
5.00m @ 2.07g/t Au in hole
24LBAC079 and 3.00m @ 0.73g/t
Au in hole 24BLAC029. Follow-up RC drilling programs are in
planning for the March quarter.
Southern Goldfields
RESOURCE DEVELOPMENT ACTIVITIES
Beta Hunt (Kambalda)
Westgold is continuing to work through legacy infrastructure
constraints to increase the rate of geological data capture at Beta
Hunt. The number of rigs available on site has increased to seven,
with the Company remaining focused on acquiring enough data to
enable a Maiden Mineral Resource Estimate to be undertaken for the
Flecher zone in the soonest possible timeframe.
To this end, initial results from the Westgold Fletcher drilling
campaign have been returned with better results including:
- 6.6m at 41.84g/t Au from
516m in WF440N1-05AE;
- 31m at 5.63g/t Au from
228m in WF440VD-54AE; and
- 24.6m at 6.9g/t Au from
274m in WF440VD-55AE.
Resource development work elsewhere in the mine has also
returned some impressive results during the quarter, with the
drilling currently underway in the Larkin zone. Better results
returned form drilling at Larkin this quarter include:
- 18.5m at 6.76g/t Au from
119m in LL320-07AG;
- 2m at 30.6g/t Au from
105m in LL395INC-07AR; and
- 14.85m at 3.61g/t Au from
165m in LL395INC-11AR
Higginsville
The first drill platform at the Two Boys underground operation
was completed during the quarter, allowing resource extension
drilling activities to subsequently commence. It is envisaged that
this initial Westgold drill program at Two Boys will continue for
the bulk of Q3 FY25, with the results allowing Westgold to solidify
the Two Boys mine plan.
At Lake Cowan, resource definition drilling at Atreides and
Harkonnen was completed. Subsequently, drilling activities
progressed onto grade control works which were ongoing at quarter's
end. It is envisaged that grade control drilling will be concluded
in mid-January, allowing a resumption of open mining activity in
Higginsville prior to the end of Q3 FY25. Better results returned
from this resource development work include:
- 4m at 6.52g/t Au from
17m in KHKRC0046;
- 18m at 1.54g/t Au from
27m in KHKRC0047; and
- 4m at 10.57g/t Au from
10m in KHKRC0075.
Initial evaluation and mine planning studies were completed on
the southern Higginsville Line of Lode underground targets.
Although these studies are preliminary, the metrics generated were
sufficiently encouraging to allow Westgold to contemplate a first
phase of resource drilling. This drilling will be planned over the
coming months and is expected to commence following the completion
of the first phase of drilling at Two Boys.
GREENFIELDS ACTIVITIES
Greenfields activities in the Southern Goldfields region
continued with a focus on the development of accelerated
exploration plans for both Beta Hunt and the Higginsville region
with planning, target reviews and the ongoing development of
drilling programs undertaken during the quarter.
In addition to the target generation works, 20 RC holes for
4,021m were drilled testing the Erin
and Bandido targets and 2 diamond core holes of 480m were drilled at the Erin target. Erin and
Bandido are located proximal to the Higginsville mill. Assay
results for these holes had not been received at the end of the
quarter.
Greenfields targeting at Beta Hunt accelerated during the period
with the construction of a new 3D Exploration model for the entire
sub-lease area. This model will become the key targeting tool for
new discoveries proximal to the existing mining operations. The
southeast extension of the Mason system has been identified as the
priority target with program drill design underway.

Debt
On 28 October 2024 Westgold
announced it had executed a commitment letter with its existing
lenders to increase its $100M
Syndicated Facility Agreement to $300M through the addition of a new $200M facility. The new $200M facility strengthens the Company's balance
sheet by providing access to a total of $300M of facilities that may be utilised for
general corporate purposes.
At quarter end Westgold had drawn down $50M from its Corporate Facilities to balance the
working capital requirements for operations and growth of a much
larger business. This leaves a balance of $250M in undrawn capacity. Combined with its cash
balance of $152M, the Company had at
the end of the quarter, $402M in
available liquidity.
The Company has equipment financing arrangements on acquired
plant and equipment under normal commercial terms with expected
repayments of approximately $44M for
the financial year.
Gold Hedging
Westgold is fully unhedged and completely leveraged to the
gold price with an achieved gold price of $4,066/oz for Q2 FY25 (Q1 FY25 $3,723/oz).

Strategic Review – Fortnum Expansion Scoping Study
The merger with Karora has created the opportunity to
review all assets within Westgold's expanded portfolio. This review
commenced in the prior quarter, and in the current quarter, it
delivered a scoping study outlining the potential for an expansion
of the Fortnum Gold Operation, located 140km north of
Meekatharra[2].
The study outlines a 10-year integrated mine plan, including the
Starlight, Nathan's, and Yarlarweelor open pits, and an expansion
of the existing Starlight underground operation. The updated
Mineral Resource Estimate for Starlight is now 12.9Mt at 2.7g/t Au
for 1.13Moz, a 91% increase from previous estimates.
Key highlights of the Study include:
- Mill expansion: From 0.9Mtpa to 1.5Mtpa.
- Life of Mine (LOM) gold production: 713koz – 871koz at an
All-In Sustaining Cost (AISC) range of $1,404 – $2,916/oz.
- Financial metrics: Mid-point NPV₈ of $306M at $3,500/oz
gold price, increasing to $498M at
$4,000/oz; mid-point free cash flow
of $777M at $3,500/oz, rising to $1.2B at $4,000/oz.
- Capital investment: Approximately $294M over the LOM, with modest upfront capital
costs.
The study indicates that the Fortnum Expansion Project is
financially viable and materially derisked, with plans to advance
drilling and evaluation to support a Final Investment Decision
within 12 months.
Crown Prince Ore
Purchase
On 12 December 2024, Westgold
announced a gold ore purchase agreement with Zeus Mining Pty Ltd, a
subsidiary of New Murchison Gold Limited (NMG). This agreement,
pending NMG shareholder approval, involves Westgold purchasing
30,000 to 50,000 tonnes of gold ore per month from NMG's Crown
Prince open pit operation, starting mid-2025. The ore will be
processed at Westgold's Bluebird plant, increasing production and
reducing costs at the operation.
This collaboration is expected to benefit both companies by
leveraging existing infrastructure and unlocking value for NMG
shareholders without the need for additional capital investment.
The initial term of the agreement is two years, with potential
extensions on a quarterly basis.
OTCQX trading
In August 2024, Westgold commenced
trading on the TSX, providing North American investors
unprecedented access to Westgold securities. With the TSX listing
well established, Westgold has elected to discontinue trading on
the OTCQX Best Market, resulting in its WGXRF securities
recommencing trading on the Pink market.

Appendix B – JORC 2012 Table 1– Gold Division
SECTION 1: SAMPLING TECHNIQUES AND DATA
(Criteria in this section apply to all succeeding sections.)
Criteria
|
JORC Code
Explanation
|
Commentary
|
Sampling
techniques
Drilling
techniques
Drill sample
recovery
|
- Nature and quality
of sampling (e.g. cut channels, random chips, or specific
specialised industry standard measurement tools appropriate to the
minerals under investigation, such as down hole gamma sondes, or
handheld XRF instruments, etc.). These examples should not be taken
as limiting the broad meaning of sampling.
- Include reference
to measures taken to ensure sample representivity and the
appropriate calibration of any measurement tools or systems
used.
- Aspects of the
determination of mineralisation that are Material to the Public
Report.
- In cases where
'industry standard' work has been done this would be relatively
simple (e.g. 'reverse circulation drilling was used to obtain 1 m
samples from which 3 kg was pulverised to produce a 30 g charge for
fire assay'). In other cases more explanation may be required, such
as where there is coarse gold that has inherent sampling problems.
Unusual commodities or mineralisation types (e.g. submarine
nodules) may warrant disclosure of detailed
information.
- Drill type (e.g.
core, reverse circulation, open-hole hammer, rotary air blast,
auger, Bangka, sonic, etc.) and details (e.g. core diameter, triple
or standard tube, depth of diamond tails, face-sampling bit or
other type, whether core is oriented and if so, by what method,
etc.).
- Method of recording
and assessing core and chip sample recoveries and results
assessed.
- Measures taken to
maximise sample recovery and ensure representative nature of the
samples.
- Whether a
relationship exists between sample recovery and grade and whether
sample bias may have occurred due to preferential loss/gain of
fine/coarse material.
|
- Diamond
Drilling
A significant portion
of the data used in resource calculations has been gathered from
diamond core. Multiple sizes have been used historically. This core
is geologically logged and subsequently halved for sampling. Grade
control holes may be whole-cored to streamline the core handling
process if required.
- Face
Sampling
At each of the major
past and current underground producers, each development face /
round is horizontally chip sampled. The sampling intervals are
domained by geological constraints (e.g. rock type, veining and
alteration / sulphidation etc.). The majority of exposures within
the orebody are sampled.
- Sludge
Drilling
Sludge drilling at is
performed with an underground production drill rig. It is an open
hole drilling method using water as the flushing medium, with a
64mm (nominal) hole diameter. Sample intervals are ostensibly the
length of the drill steel. Holes are drilled at sufficient angles
to allow flushing of the hole with water following each interval to
prevent contamination. Sludge drilling is not used to inform
resource models.
- RC
Drilling
Drill cuttings are
extracted from the RC return via cyclone. The underflow from each
interval is transferred via bucket to a four-tiered riffle
splitter, delivering approximately three kilograms of the recovered
material into calico bags for analysis. The residual material is
retained on the ground near the hole. Composite samples are
obtained from the residue material for initial analysis, with the
split samples remaining with the individual residual piles until
required for re-split analysis or eventual disposal.
- RAB / Aircore
Drilling
Combined scoops from
bucket dumps from cyclone for composite. Split samples taken from
individual bucket dumps via scoop. RAB holes are not included in
the resource estimate.
- Blast Hole
Drilling
Cuttings sampled via
splitter tray per individual drill rod. Blast holes not included in
the resource estimate. All
geology input is logged and validated by the relevant area
geologists, incorporated into this is assessment of sample
recovery. No defined relationship exists between sample recovery
and grade. Nor has sample bias due to preferential loss or gain of
fine or coarse material been noted.
|
Logging
|
- Whether core and
chip samples have been geologically and geotechnically logged to a
level of detail to support appropriate Mineral Resource estimation,
mining studies and metallurgical studies.
- Whether logging is
qualitative or quantitative in nature. Core (or costean, channel,
etc.) photography.
- The total length
and percentage of the relevant intersections logged
|
- Westgold surface
drill-holes are all orientated and have been logged in detail for
geology, veining, alteration, mineralisation and orientated
structure. Westgold underground drill-holes are logged in detail
for geology, veining, alteration, mineralisation and structure.
Core has been logged in enough detail to allow for the relevant
mineral resource estimation techniques to be employed.
- Surface core is
photographed both wet and dry and underground core is photographed
wet. All photos are stored on the Company's servers, with the
photographs from each hole contained within separate
folders.
- Development faces
are mapped geologically.
- RC, RAB and Aircore
chips are geologically logged.
- Sludge drilling is
logged for lithology, mineralisation and vein
percentage.
- Logging is both
qualitative and quantitative in nature.
- All holes are
logged completely, all faces are mapped completely.
|
Sub-sampling
techniques
and sample preparation
|
- If core, whether
cut or sawn and whether quarter, half or all core
taken.
- If non-core,
whether riffled, tube sampled, rotary split, etc. and whether
sampled wet or dry.
- For all sample
types, the nature, quality and appropriateness of the sample
preparation technique.
- Quality control
procedures adopted for all sub-sampling stages to maximise
representivity of samples.
- Measures taken to
ensure that the sampling is representative of the in-situ material
collected, including for instance results for field
duplicate/second-half sampling.
- Whether sample
sizes are appropriate to the grain size of the material being
sampled.
|
- Blast holes
-Sampled via splitter tray per individual drill rods.
- RAB / AC chips -
Combined scoops from bucket dumps from cyclone for composite. Split
samples taken from individual bucket dumps via scoop.
- RC - Three tier
riffle splitter (approximately 5kg sample). Samples generally
dry.
- Face Chips -
Nominally chipped horizontally across the face from left to right,
sub-set via geological features as appropriate.
- Diamond Drilling -
Half-core niche samples, sub-set via geological features as
appropriate. Grade control holes may be whole-cored to streamline
the core handling process if required.
- Chips / core chips
undergo total preparation.
- Samples undergo
fine pulverisation of the entire sample by an LM5 type mill to
achieve a 75µ product prior to splitting.
- QA/QC is currently
ensured during the sub-sampling stages process via the use of the
systems of an independent NATA / ISO accredited laboratory
contractor. A significant portion of the historical informing data
has been processed by in-house laboratories.
- The sample size is
considered appropriate for the grain size of the material being
sampled.
- The un-sampled half
of diamond core is retained for check sampling if required. For RC
chips regular field duplicates are collected and analysed for
significant variance to primary results.
|
Quality of assay
data and
laboratory tests
|
- The nature, quality
and appropriateness of the assaying and laboratory procedures used
and whether the technique is considered partial or
total.
- For geophysical
tools, spectrometers, handheld XRF instruments, etc., the
parameters used in determining the analysis including instrument
make and model, reading times, calibrations factors applied and
their derivation, etc.
- Nature of quality
control procedures adopted (e.g. standards, blanks, duplicates,
external laboratory checks) and whether acceptable levels of
accuracy (i.e. lack of bias) and precision have been
established.
|
- Recent sampling was
analysed by fire assay as outlined below;
- A 40g – 50g sample
undergoes fire assay lead collection followed by flame atomic
adsorption spectrometry.
- The laboratory
includes a minimum of 1 project standard with every 22 samples
analysed.
- Quality control is
ensured via the use of standards, blanks and
duplicates.
- No significant
QA/QC issues have arisen in recent drilling results.
- Photon Assay was
introduced in 2023 for Beta Hunt grade control samples.
PhotonAssay™ technology (Chrysos Corporation Limited) is a rapid,
non-destructive analysis of gold and other elements in mineral
samples. It is based on the principle of gamma activation, which
uses high energy x-rays to excite changes to the nuclear structure
of selected elements. The decay is then measured to give a gold
analysis. Each sample is run through two cycles with a radiation
time of 15s. This methodology is insensitive to material type and
thus does not require fluxing chemicals as in the fire assay
methodology. Highlights of the PhotonAssay™ process are as
follows:
- The process is
non-destructive; the same sample accuracy can be determined by
repeat measurements of the same sample. In addition, the instrument
runs a precision analysis for each sample relating to the
instrument precision
- The process allows
for an increased sample size, about 500 g of crushed
product.
- The crushed
material is not pulverised, as in the fire assay process; this
ensures that gold is not smeared or lost during pulverisation
(especially important if there is an expectation of visible gold
that is being analysed)
- Historical drilling
has used a combination of Fire Assay, Aqua Regia and PAL
analysis.
- These assay
methodologies are appropriate for the resources in
question.
|
Verification of
sampling and
assaying
|
- The verification of
significant intersections by either independent or alternative
company personnel.
- The use of twinned
holes.
- Documentation of
primary data, data entry procedures, data verification, data
storage (physical and electronic) protocols.
- Discuss any
adjustment to assay data.
|
- No independent or
alternative verifications are available.
- Virtual twinned
holes have been drilled in several instances across all sites with
no significant issues highlighted. Drillhole data is also routinely
confirmed by development assay data in the operating
environment.
- Primary data is
collected utilising LogChief. The information is imported into a
SQL database server and verified.
- All data used in
the calculation of resources and reserves are compiled in databases
(underground and open pit) which are overseen and validated by
senior geologists.
- No adjustments have
been made to any assay data.
|
Location of data
points
|
- Accuracy and
quality of surveys used to locate drill holes (collar and down-hole
surveys), trenches, mine workings and other locations used in
Mineral Resource estimation.
- Specification of
the grid system used.
- Quality and
adequacy of topographic control.
|
- All data is
spatially oriented by survey controls via direct pickups by the
survey department. Drillholes are all surveyed downhole, deeper
holes with a Gyro tool if required, the majority with single /
multishot cameras.
- All drilling and
resource estimation is preferentially undertaken in local mine grid
at the various sites.
- Topographic control
is generated from a combination of remote sensing methods and
ground-based surveys. This methodology is adequate for the
resources in question.
|
Data spacing and
distribution
|
- Data spacing for
reporting of Exploration Results.
- Whether the data
spacing and distribution is sufficient to establish the degree of
geological and grade continuity appropriate for the Mineral
Resource and Ore Reserve estimation procedure(s) and
classifications applied.
- Whether sample
compositing has been applied.
|
- Data spacing is
variable dependent upon the individual orebody under consideration.
A lengthy history of mining has shown that this approach is
appropriate for the Mineral Resource Estimation process and to
allow for classification of the resources as they
stand.
- Compositing is
carried out based upon the modal sample length of each individual
domain.
|
Orientation of data
in relation
to geological structure
|
- Whether the
orientation of sampling achieves unbiased sampling of possible
structures and the extent to which this is known, considering the
deposit type.
- If the relationship
between the drilling orientation and the orientation of key
mineralised structures is considered to have introduced a sampling
bias, this should be assessed and reported if material.
|
- Drilling
intersections are nominally designed to be normal to the orebody as
far as underground infrastructure constraints / topography
allows.
- Development
sampling is nominally undertaken normal to the various
orebodies.
- Where drilling
angles are sub optimal the number of samples per drill hole used in
the estimation has been limited to reduce any potential
bias.
- It is not
considered that drilling orientation has introduced an appreciable
sampling bias.
|
Sample
security
|
- The measures taken
to ensure sample security.
|
- For samples assayed
at on-site laboratory facilities, samples are delivered to the
facility by Company staff. Upon delivery the responsibility for
sample security and storage falls to the independent third-party
operators of these facilities.
- For samples assayed
off-site, samples are delivered to a third-party transport service,
who in turn relay them to the independent laboratory contractor.
Samples are stored securely until they leave site.
|
Audits or
reviews
|
- The results of any
audits or reviews of sampling techniques and data
|
- Site generated
resources and reserves and the parent geological data is routinely
reviewed by the Westgold Corporate technical team.
|

|
Geology
|
- Deposit type,
geological setting and style of mineralisation.
|
BHO
- Beta Hunt is
situated within the central portion of the Norseman-Wiluna
greenstone belt in a sequence of mafic/ultramafic and felsic rocks
on the southwest flank of the Kambalda Dome.
- Gold mineralisation
occurs mainly in subvertical shear zones in the Lunnon Basalt and
is characterised by shear and extensional quartz veining within a
halo of biotite/pyrite alteration. Within these shear zones, coarse
gold sometimes occurs where the shear zones intersect iron-rich
sulphidic metasediments in the Lunnon Basalt or nickel sulphides at
the base of the Kambalda Komatiite (ultramafics). The mineralised
shears are represented by A-Zone, Western Flanks, Larkin and Mason
zones.
|
|
|
CGO
- CGO is located in
the Achaean Murchison Province, a granite-greenstone terrane in the
northwest of the Yilgarn Craton. Greenstone belts trending
north-northeast are separated by granite-gneiss domes, with smaller
granite plutons also present within or on the margins of the
belts.
- Mineralisation at
Big Bell is hosted in the shear zone (Mine Sequence) and is
associated with the post-peak metamorphic retrograde assemblages.
Stibnite, native antimony and trace arsenopyrite are disseminated
through the K-feldspar-rich lode schist. These are intergrown with
pyrite and pyrrhotite and chalcopyrite. Mineralisation outside the
typical Big Bell host rocks (KPSH), for example 1,600N and Shocker,
also display a very strong W-As-Sb geochemical halo.
- Numerous gold
deposits occur within the Cuddingwarra Project area, the majority
of which are hosted within the central mafic-ultramafic ± felsic
porphyry sequence. Within this broad framework, mineralisation is
shown to be spatially controlled by competency contrasts across,
and flexures along, layer-parallel D2 shear zones, and is maximised
when transected by corridors of northeast striking D3 faults and
fractures.
- The Great Fingall
Dolerite hosts the majority gold mineralisation within the portion
of the greenstone belt proximal to Cue (The Day Dawn Project Area).
Unit AGF3 is the most brittle of all the five units and this
characteristic is responsible for its role as the most favourable
lithological host to gold mineralisation in the Greenstone
Belt.
|
|
|
FGO
- The Fortnum
deposits are Paleoproterozoic shear-hosted gold deposits within the
Fortnum Wedge, a localised thrust duplex of Narracoota Formation
within the overlying Ravelstone Formation. Both stratigraphic
formations comprise part of the Bryah Basin in the Capricorn
Orogen, Western Australia.
- The Horseshoe
Cassidy deposits are hosted within the Ravelstone Formation
(siltstone and argillite) and Narracoota Formation (highly altered,
moderate to strongly deformed mafic to ultramafic rocks). The main
zone of mineralisation is developed within a horizon of highly
altered magnesian basalt. Gold mineralisation is associated with
strong vein stock works that are confined to the altered mafic.
Alteration consists of two types: stockwork proximal
silica-carbonate-fuchsite-haematite-pyrite and distal
silica-haematite-carbonate+/- chlorite.
- The Peak Hill
district represents remnants of a Proterozoic fold belt comprising
highly deformed trough and shelf sediments and mafic / ultramafic
volcanics, which are generally moderately metamorphosed (except for
the Peak Hill Metamorphic Suite).
|
|
|
HGO
- The Higginsville
Gold Operation is located in the Eastern Goldfields Superterrane of
the Archean Yilgarn Craton. The bulk of the Higginsville tenement
package is located almost entirely within the well-mineralised
Kalgoorlie Terrane, between the gold mining centres of Norseman and
St Ives. HGO can be sub-divided into seven major geological
domains: Trident Line of Lode, Chalice, Lake Cowan, Southern
Paleo-channels, Mt Henry, Polar Bear Group and Spargos Project
area.
- Majority of
mineralisation along the Trident Line of Lode are hosted within the
Poseidon gabbro and high-MgO dyke complexes in the south. The
Poseidon Gabbro is a thick, weakly-differentiated gabbroic sill,
which strikes north-south and dips 60° to the east, is over 500 m
thick and 2.5 km long. The mineralisation is hosted within or
marginal to quartz veining and is structurally and lithologically
controlled.
- The Chalice Deposit
is located within a north-south trending, 2 km to 3 km wide
greenstone terrane, flanked on the west calc-alkaline granitic
rocks of the Boorabin Batholith and to the east by the Pioneer Dome
Batholith. The dominant unit that hosts gold mineralisation is a
fine grained, weak to strongly foliated amphibole-plagioclase
amphibolite, with a typically lepidoblastic (mineralogically
aligned and banded) texture. It is west-dipping and generally
steep, approximately 60° to 75°.
- The Lake Cowan
project area is situated near the centre of a regional anticline
between the Zuleika and Lefroy faults, with the local geology of
the area made more complex by the intrusion of the massive
Proterozoic Binneringie dyke. The majority of mineralisation at the
Lake Cowan Mining Centre is hosted within an enclave of Archaean
material surrounded by the Binneringie dyke.
- Mineralised zones
within the Southern Paleo Channels network comprise both placer
gold, normally near the base of the channel-fill sequences, and
chemically-precipitated secondary gold within the channel-fill
materials and underlying saprolite. These gold concentrations
commonly overlie, or are adjacent to, primary mineralised zones
within Archaean bedrock.
- The Mount Henry
Project covers 347km2 of the prolific South Norseman‐Wiluna
Greenstone belt of the Eastern Goldfields in Western Australia.
Although the greenstone rocks from the Norseman area can be broadly
correlated with those of the Kalgoorlie – Kambalda region they form
a distinct terrain which is bounded on all sides by major regional
shears. The Norseman Terrane has prominent banded iron formations
which distinguish it from the Kalgoorlie– Kambalda Terrane. The
Mount Henry gold deposit is hosted by a silicate facies BIF unit
within the Noganyer Formation. Gold mineralisation is predominantly
hosted by the silicate facies BIF unit but is also associated with
minor meta‐basalt and dolerite units that were mostly emplaced in
the BIF prior to mineralisation. The footwall to the BIF is
characterised by a sedimentary schistose unit and the hanging wall
by the overlying dolerites of the Woolyeener Formation. The Mount
Henry gold deposit is classified as an Archean, orogenic shear
hosted deposit. The main lode is an elongated, shear‐hosted body,
1.9km long by 6 – 10 metres wide and dips 65‐75 degrees towards the
west.
- The Polar Bear
project is situated within the Archaean Norseman-Wiluna Belt which
locally includes basalts, komatiites, metasediments, and felsic
volcaniclastics. The primary gold mineralisation is related to
hydrothermal activity during multiple deformation events.
Indications are that gold mineralisation is focused on or near to
the stratigraphic boundary between the Killaloe and Buldania
Formation.
- The Spargos Project
occurs within Coolgardie Domain of the Kalgoorlie Terrane. The area
is bounded by the Zuleika Shear to the east and the Kunanalling
Shear to the west. The geological setting comprises tightly-folded
north-south striking ultramafic and mafic volcanic rocks at the
northern closure Widgiemooltha Dome. The project lies on the
general trend of the Kunanalling / Karramindie Shear corridor, a
regional shear zone that hosts significant mineralisation to the
north at Ghost Crab (Mount Marion), Wattle Dam to the south, the
Penfolds group and Kunanalling. The regional prospective Zuleika
Shear lies to the east of the project. The tenements are
prospective for vein and shear hosted gold deposits as demonstrated
by Spargos Reward and numerous other gold workings and occurrences.
Gold mineralisation at Spargos Reward is hosted by a coarse-grained
pyrite-arsenopyrite lode in quartz-sericite schists, between
strongly biotitic altered greywacke to the east and
quartz-sericite-fuchsite-pyrite altered felsic tuff to the west.
Gold mineralisation is associated with very little quartz veining
which is atypical for many deposits in region. The Spargos Reward
setting has been described variously as a low-quartz sulphidic
mesothermal gold system or as a Hemlo style syn-sedimentary
occurrence.
MGO
- MGO is located in
the Achaean Murchison Province, a granite-greenstone terrane in the
northwest of the Yilgarn Craton. Greenstone belts trending
north-northeast are separated by granite-gneiss domes, with smaller
granite plutons also present within or on the margins of the
belts.
- The Paddy's Flat
area is located on the western limb of a regional fold, the Polelle
Syn- cline, within a sequence of mafic to ultramafic volcanics with
minor interflow sediments and banded iron-formation. The sequence
has also been intruded by felsic porphyry dykes prior to
mineralisation. Mineralisation is located along four sub-parallel
trends at Paddy's Flat which can be summarized as containing three
dominant mineralisation styles:
- Sulphide
replacement BIF hosted gold. Quartz vein hosted shear-related
gold.
- Quartz-carbonate-sulphide stockwork vein and
alteration related gold.
- The Yaloginda area
which host Bluebird – South Junction, is a gold-bearing Archaean
greenstone belt situated ~15km south of Meekatharra. The deposits
in the area are hosted in a strained and metamorphosed volcanic
sequence that consists primarily of ultramafic and high-magnesium
basalt with minor komatiite, peridotite, gabbro, tholeiitic basalt
and interflow sediments. The sequence was intruded by a variety of
felsic porphyry and intermediate sills and dykes.
- The Reedy's mining
district is located approximately 15 km to the south-east to
Meekatharra and to the south of Lake Annean. The Reedy gold
deposits occur with- in a north-south trending greenstone belt, two
to five kilometres wide, composed of volcano-sedimentary sequences
and separated multiphase syn- and post-tectonic granitoid
complexes. Structurally controlled the gold occur.

Drill hole
Information
|
- A summary of all
information material to the understanding of the exploration
results including a tabulation of the following information for all
Material drill holes:
- easting and
northing of the drill hole collar
- elevation or RL
(Reduced Level – elevation above sea level in metres) of the drill
hole collar
- dip and azimuth of
the hole
- down hole length
and interception depth
- hole
length.
- If the exclusion of
this information is justified on the basis that the information is
not Material and this exclusion does not detract from the
understanding of the report, the Competent Person should clearly
explain why this is the case.
|
- Tables containing
drillhole collar, downhole survey and intersection data are
included in the body of the announcement.
- No explorations
results are being reported for Beta Hunt and Higginsville
Operations.
|
Data aggregation
methods
|
- In reporting
Exploration Results, weighting averaging techniques, maximum and/or
minimum grade truncations (e.g., cutting of high grades) and
cut-off grades are usually Material and should be
stated.
- Where aggregate
intercepts incorporate short lengths of high-grade results and
longer lengths of low-grade results, the procedure used for such
aggregation should be stated and some typical examples of such
aggregations should be shown in detail.
- The assumptions
used for any reporting of metal equivalent values should be clearly
stated.
|
- All results
presented are length weighted.
- No high-grade cuts
are used.
- Reported results
contain no more than two contiguous metres of internal dilution
below 0.5g/t. For Beta Hunt, a cut off of 1 g/t Au with maximum
internal waste of 2m is used to define significant
intercepts.
- Results are
reported above a variety of gram / metre cut-offs dependent upon
the nature of the hole. These are cut-offs are clearly stated in
the relevant tables.
- Unless indicated to
the contrary, all results reported are downhole width.
- Given restricted
access in the underground environment the majority of drillhole
intersections are not normal to the orebody.
|
Relationship
between
mineralisation widths and
intercept lengths
|
- These relationships
are particularly important in the reporting of Exploration
Results.
- If the geometry of
the mineralisation with respect to the drill hole angle is known,
its nature should be reported.
- If it is not known
and only the down hole lengths are reported, there should be a
clear statement to this effect (e.g., 'down hole length, true width
not known').
|
- Unless indicated to
the contrary, all results reported are downhole width.
- Given restricted
access in the underground environment the majority of drillhole
intersections are not normal to the orebody.
|
Diagrams
|
- Appropriate maps
and sections (with scales) and tabulations of intercepts should be
included for any significant discovery being reported These should
include, but not be limited to a plan view of drill hole collar
locations and appropriate sectional views.
|
- Appropriate
diagrams are provided in the body of the release if
required.
|
Balanced
reporting
|
- Where comprehensive
reporting of all Exploration Results is not practicable,
representative reporting of both low and high grades and/or widths
should be practiced to avoid misleading reporting of Exploration
Results.
|
- Appropriate balance
in exploration results reporting is provided.
|
Other substantive
exploration
data
|
- Other exploration
data, if meaningful and material, should be reported including (but
not limited to): geological observations; geophysical survey
results; geochemical survey results; bulk samples – size and method
of treatment; metallurgical test results; bulk density,
groundwater, geotechnical and rock characteristics; potential
deleterious or contaminating substances.
|
- There is no other
substantive exploration data associated with this
release.
|
Further
work
|
- The nature and
scale of planned further work (e.g. tests for lateral extensions or
depth extensions or large-scale step-out drilling).
- Diagrams clearly
highlighting the areas of possible extensions, including the main
geological interpretations and future drilling areas, provided this
information is not commercially sensitive.
|
- Ongoing surface and
underground exploration activities will be undertaken to support
continuing mining activities at Westgold Gold
Operations.

Geological
interpretation
|
- Confidence in (or
conversely, the uncertainty of) the geological interpretation of
the mineral deposit.
- Nature of the data
used and of any assumptions made.
- The effect, if any,
of alternative interpretations on Mineral Resource
estimation.
- The use of geology
in guiding and controlling Mineral Resource estimation.
- The factors
affecting continuity both of grade and geology.
|
- Mining in the
Murchison and Goldfields districts has occurred since 1800's
providing significant confidence in the currently geological
interpretation across all projects.
- Confidence in the
geological interpretation is high. The current geological
interpretation has been a precursor to successful mining over the
years and forms the basis for the long-term life of mine plan
(LOM). The data and assumptions used do suggest that any
significant alternative geological interpretation is
unlikely.
- Geology
(lithological units, alterations, structure, veining) have been
used to guide and control Mineral Resource estimation .
- No alternative
interpretations are currently considered viable.
- Geological
interpretation of the deposit was carried out using a systematic
approach to ensure that the resultant estimated Mineral Resource
figure was both sufficiently constrained, and representative of the
expected sub-surface conditions. In all aspects of resource
estimation the factual and interpreted geology was used to guide
the development of the interpretation.
- Geological matrixes
were established to assist with interpretation and construction of
the estimation domains.
- The structural
regime is the dominant control on geological and grade continuity
in the Murchison and Goldfields. Lithological factors such as
rheology contrast are secondary controls on grade
distribution.
- Low-grade
stockpiles are derived from previous mining of the mineralisation
styles outlined above.

STOCKPILES
- Low-grade
stockpiles are of various dimensions. All modelling and estimation
work undertaken by Westgold is carried out in three dimensions via

|
Estimation and
modelling techniques.
|
- The nature and
appropriateness of the estimation technique(s) applied and key
assumptions, including treatment of extreme grade values,
domaining, interpolation parameters, maximum distance of
extrapolation from data points.
- The availability of
check estimates, previous estimates and/or mine production records
and whether the Mineral Resource estimate takes appropriate account
of such data.
- The assumptions
made regarding recovery of by-products.
- Estimation of
deleterious elements or other non-grade variables of economic
significance (e.g. sulphur for acid mine drainage
characterisation).
- In the case of
block model interpolation, the block size in relation to the
average sample spacing and the search employed.
- Any assumptions
behind modelling of selective mining units.
- Any assumptions
about correlation between variables.
- The process of
validation, the checking process used, the comparison of model data
to drillhole data, and use of reconciliation data if
available.
|
- After validating
the drillhole data to be used in the estimation, interpretation of
the orebody is undertaken in sectional and / or plan view to create
the outline strings which form the basis of the three-dimensional
orebody wireframe. Wireframing is then carried out using a
combination of automated stitching algorithms and manual
triangulation to create an accurate three-dimensional
representation of the sub-surface mineralised body.
- Drillhole
intersections within the mineralised body are defined, these
intersections are then used to flag the appropriate sections of the
drillhole database tables for compositing purposes. Drillholes are
subsequently composited to allow for grade estimation. In all
aspects of resource estimation, the factual and interpreted geology
was used to guide the development of the
interpretation.
- Once the sample
data has been composited, a statistical analysis is undertaken to
assist with determining estimation search parameters, top-cuts etc.
Variographic analysis of individual domains is undertaken to assist
with determining appropriate search parameters. Which are then
incorporated with observed geological and geometrical features to
determine the most appropriate search parameters.
- An empty block
model is then created for the area of interest. This model contains
attributes set at background values for the various elements of
interest as well as density, and various estimation parameters that
are subsequently used to assist in resource categorisation. The
block sizes used in the model will vary depending on orebody
geometry, minimum mining units, estimation parameters and levels of
informing data available.
- Grade estimation is
then undertaken, with ordinary kriging estimation method is
considered as standard, although in some circumstances where sample
populations are small, or domains are unable to be accurately
defined, inverse distance weighting estimation techniques will be
used. For very minor lodes, the respective median or average grade
is assigned. Both by-product and deleterious elements are estimated
at the time of primary grade estimation if required. It is assumed
that by- products correlate well with gold. There are no
assumptions made about the recovery of by-products.
- The resource is
then depleted for mining voids and subsequently classified in line
with JORC guidelines utilising a combination of various estimation
derived parameters and geological / mining knowledge.
- This approach has
proven to be applicable to Westgold's gold assets.
- Estimation results
are routinely validated against primary input data, previous
estimates and mining output.
- Good reconciliation
between mine claimed figures and milled figures are routinely
achieved during production.
|
Moisture
|
- Whether the
tonnages are estimated on a dry basis or with natural moisture, and
the method of determination of the moisture content.
|
- Tonnage estimates
are dry tonnes.
|
Cut-off
parameters
|
- The basis of the
adopted cut-off grade(s) or quality parameters applied.
|
- The cut off grades
used for the reporting of the Mineral Resources have been selected
based on the style of mineralisation, depth from surface of the
mineralisation and the most probable extraction technique and
associated costs.
|
Mining factors or
assumptions
|
- Assumptions made
regarding possible mining methods, minimum mining dimensions and
internal (or, if applicable, external) mining dilution. It is
always necessary as part of the process of determining reasonable
prospects for eventual economic extraction to consider potential
mining methods, but the assumptions made regarding mining methods
and parameters when estimating Mineral Resources may not always be
rigorous. Where this is the case, this should be reported with an
explanation of the basis of the mining assumptions
made.
|
- Variable by
deposit.
- No mining dilution
or ore loss has been modelled in the resource model or applied to
the reported Mineral Resource.
|
Metallurgical
factors or
assumptions
|
- The basis for
assumptions or predictions regarding metallurgical amenability. It
is always necessary as part of the process of determining
reasonable prospects for eventual economic extraction to consider
potential metallurgical methods, but the assumptions regarding
metallurgical treatment processes and parameters made when
reporting Mineral Resources may not always be rigorous. Where this
is the case, this should be reported with an explanation of the
basis of the metallurgical assumptions made.
|
- Not considered for
Mineral Resource. Applied during the Reserve generation
process.
|
Environmental
factors or
assumptions
|
- Assumptions made
regarding possible waste and process residue disposal options. It
is always necessary as part of the process of determining
reasonable prospects for eventual economic extraction to consider
the potential environmental impacts of the mining and processing
operation. While at this stage the determination of potential
environmental impacts, particularly for a greenfields project, may
not always be well advanced, the status of early consideration of
these potential environmental impacts should be reported. Where
these aspects have not been considered this should be reported with
an explanation of the environmental assumptions made.
|
- Westgold operates
in accordance with all environmental conditions set down as
conditions for grant of the respective leases.
|
Bulk
density
|
- Whether assumed or
determined. If assumed, the basis for the assumptions. If
determined, the method used, whether wet or dry, the frequency of
the measurements, the nature, size and representativeness of the
samples.
- The bulk density
for bulk material must have been measured by methods that
adequately account for void spaces (vugs, porosity, etc.), moisture
and differences between rock and alteration zones within the
deposit.
- Discuss assumptions
for bulk density estimates used in the evaluation process of the
different materials.
|
- Bulk density of the
mineralisation is variable and is for the most part lithology and
oxidation rather than mineralisation dependent.
- A large suite of
bulk density determinations has been carried out across the project
areas. The bulk densities were separated into different weathering
domains and lithological domains.
- A significant past
mining history has validated the assumptions made surrounding bulk
density.
|
Classification
|
- The basis for the
classification of the Mineral Resources into varying confidence
categories.
- Whether appropriate
account has been taken of all relevant factors (i.e. relative
confidence in tonnage/grade estimations, reliability of input data,
confidence in continuity of geology and metal values, quality,
quantity and distribution of the data).
- Whether the result
appropriately reflects the Competent Person's view of the
deposit.
|
- Resources are
classified in line with JORC guidelines utilising a combination of
various estimation derived parameters, input data and geological /
mining knowledge.
- Drillhole spacing
to support classification varies based upon lode characteristics.
Measured ranges from 15-35m, Indicated from 10-180m and Inferred
from 10-200m.
- This approach
considers all relevant factors and reflects the Competent Person's
view of the deposit.
|
Audits or
reviews
|
- The results of any
audits or reviews of Mineral Resource estimates.
|
- Resource estimates
are peer reviewed by the Corporate technical team.
- No external reviews
have been undertaken.
|
Discussion of
relative accuracy/ confidence
|
- Where appropriate a
statement of the relative accuracy and confidence level in the
Mineral Resource estimate using an approach or procedure deemed
appropriate by the Competent Person. For example, the application
of statistical or geostatistical procedures to quantify the
relative accuracy of the resource within stated confidence limits,
or, if such an approach is not deemed appropriate, a qualitative
discussion of the factors that could affect the relative accuracy
and confidence of the estimate.
- The statement
should specify whether it relates to global or local estimates,
and, if local, state the relevant tonnages, which should be
relevant to technical and economic evaluation. Documentation should
include assumptions made and the procedures used.
- These statements of
relative accuracy and confidence of the estimate should be compared
with production data, where available.
|
- All currently
reported resource estimates are considered robust, and
representative on both a global and local scale.
- A continuing
history of mining with good reconciliation of mine claimed to mill
recovered provides confidence in the accuracy of the
estimates.

|
Study
status
|
- The type and level
of study undertaken to enable Mineral Resources to be converted to
Ore Reserves.
- The Code requires
that a study to at least Pre-Feasibility Study level has been
undertaken to convert Mineral Resources to Ore Reserves. Such
studies will have been carried out and will have determined a mine
plan that is technically achievable and economically viable, and
that material Modifying Factors have been considered
|
- Processing at the
Murchison operations has occurred continuously since 2015, with
previous production occurring throughout 1800's, 1900's and 2000's.
Processing at the Goldfields operations has occurred intermittently
since the 1980's and continuously since 2008 at
Higginsville.
- Various
mineralisation styles and host domains have been mined since
discovery. Mining during this time has ranged from open pit
cutbacks, insitu surface excavations to extensional underground
developments.
- Budget level, 24
month projected, forecasts are completed on a biannual basis,
validating cost and physical inventory assumptions and modelling.
These updated parameters are subsequently used for the basis of the
Ore Reserve modification and financial factors.
- Following
exploration and infill drilling activity, resource models are
updated on both the estimation of grade and classification. These
updated Mineral Resources Estimates then form the foundation for
the Ore Reserve.
•
|
Cut-off
parameters
|
- The basis of the
cut-off grade(s) or quality parameters applied.
|
- Underground Mines -
Cut off grades are used to determine the economic viability of the
convertible Mineral Resources Estimates. COG for underground mines
incorporate OPEX development and production costs, grade control,
haulage, milling, administration, along with state and private
royalty conditions, Where an individual mine has different mining
methods and or various orebody style, COG calculations are
determined for each division. These cuts are applied to production
shapes (stopes) as well as high grade development. Additionally, an
incremental COG is applied to low grade development, whereby access
to a high grade area is required.
- On the basis of
above process, the COG is split into Mine Operating COG
(incremental grade) 2.1gt and Fully Costed COG (inclusive of
capital) 2.3gt.
- Open Pit Mines -
The pit rim cut-off grade (COG) was determined as part of the Ore
Reserve. The pit rim COG accounts for grade control, haulage,
milling, administration, along with state and private royalty
conditions. This cost profile is equated against the value of the
mining block in terms of recovered metal and the expected selling
price. The COG is then used to determine whether or not a mining
block should be delivered to the treatment plant for processing,
stockpiled as low- grade or taken to the waste dump.
- On the basis of
above process, COGs for the open pit mines range from 0.8g/t
(whereby the Mill is local to mine and Mill recoveries are greater
than 90%) to 1.4g/t (regional pits with low Mill
recoveries).
- Stockpile COG – A
marginal grade was determined for each stockpile inventory to
ensure it was economically viable. The COG accounts for haulage,
milling, administration, along with state and private royalty
conditions. Each pile honoured its Mill recovery
percentage.
|
Mining factors
or
assumptions
|
- The method and
assumptions used as reported in the Pre-Feasibility or Feasibility
Study to convert the Mineral Resource to an Ore Reserve (i.e.
either by application of appropriate factors by optimisation or by
preliminary or detailed design).
- The choice, nature
and appropriateness of the selected mining method(s) and other
mining parameters including associated design issues such as
pre-strip, access, etc.
- The assumptions
made regarding geotechnical parameters (e.g. pit slopes, stope
sizes, etc.), grade control and pre-production
drilling.
- The major
assumptions made and Mineral Resource model used for pit and stope
optimisation (if appropriate).
- The mining dilution
factors used.
- The mining recovery
factors used.
- Any minimum mining
widths used.
- The manner in which
Inferred Mineral Resources are utilised in mining studies and the
sensitivity of the outcome to their inclusion.
- The infrastructure
requirements of the selected mining methods.
|
- All Ore Reserve
inventories are based upon detailed 3-dimensional designs to ensure
practical mining conditions are met. Additionally, all Ore Reserve
inventories are above the mine specific COG(s) as well as
containing only Measured and Indicated material. Depending upon the
mining method – modifying factors are used to address hydrological,
geotechnical, minimum width and blasting conditions.
Open Pit
Methodology
- The mining shape in
the Ore Reserve estimation is generated by a wireframe (geology
interpretation of the mineralisation) which overlays the block
model. Where the wire frame cuts the primary block, sub blocks fill
out the remaining space to the wire frame boundary (effectively the
mining shape). It is reasonable to assume that the mining method
can selectively mine to the wire frame boundary with the additional
dilution provision stated below.
- Ore Reserves are
based on pit designs – with appropriate modifications to the
original Whittle Shell outlines to ensure compliance with practical
mining parameters.
- Geotechnical
parameters aligned to the open pit Ore Reserves are either based on
observed existing pit shape specifics or domain specific
expectations / assumptions. Various geotechnical reports and
retrospective reconciliations were considered in the design
parameters. A majority of the open pits have a final design wall
angle of 39-46 degrees, which is seen as conservative.
- Dilution of the ore
through the mining process has been accounted for within the Ore
Reserve quoted inventory. Various dilution ratios are used to
represent the style of mineralisation. Where continuous, consistent
mineralisation boundaries and grade represent the mineralised
system the following factors are applied: oxide 15%, transitional
17% and fresh 19%. In circumstances where the orebody is less
homogenous above the COG then the following dilution factors are
applied in order to model correctly the inherent variability of
extracting discrete sections of the pit floor: oxide 17%,
transitional 19% and fresh 21%. To ensure clarity, the following
percentages are additional ore mined in relation to excavating the
wire frame boundary as identified in point 1 above, albeit at a
grade of 0.0 g/t. The amount of dilution is considered appropriate
based on mineralisation geometry, historical mining performance and
the size of mining equipment to be used to extract ore.
- Expected mining
recovery of the ore has been set at 93%.
- Minimum mining
widths have been accounted for in the designs, with the utilisation
of 40t or 90t trucking parameters depending upon the size of the
pit excavation.
- No specific ground
support requirements are needed outside of suitable pit slope
design criteria based on specific geotechnical domains.
- Mining sequence is
included in the mine scheduling process for determining the
economic evaluation and takes into account available operating time
and mining equipment size and performance.
- No Inferred
material is included within the open pit statement, though in
various pit shapes Inferred material is present. In these
situations this Inferred material is classified as
waste.

Underground
Methodology
- All underground Ore
Reserves are based on 3D design strings and polygon derived stope
shapes following the Measured and Indicated Mineral Resource
Estimates (in areas above the Mine Operating COG). A complete mine
schedule is then derived from this design to create a LoM plan and
financial analysis.
- Mining heights and
widths are based on first principles and standardised mining
methods employed widely throughout Western Australia.
- Geotechnical
evaluations have been used in determining the size and filling
methodologies. Subsequent costs associated with these methods have
been included within the study and budgeting formats.
- In large,
disseminated orebodies sub level caving, sub level open stoping or
single level bench stoping production methodologies are
used.
- In narrow vein
laminated quartz hosted domains, a conservative narrow bench style
mining method is used.
- In narrow flat
dipping deposits, a flat long hole process is adopted (with fillets
in the footwall for rill angle) and or jumbo stoping.
- Stope shape
parameters have been based on historical data (where possible) or
expected stable hydraulic radius dimensions.
- Stope inventories
have been determined by cutting the geological wireframe at above
the area specific COG and applying mining dilution and ore loss
factors. The ore loss ratio accounts for pillar locations between
the stopes (not operational ore loss) whilst dilution allows for
conversion of the geological wireframe into a minable shape
(planned dilution) as well as hangingwall relaxation and blasting
overbreak (unplanned dilution).
- Depending upon the
style of mineralisation, sub level interval, blasthole diameters
used and if secondary support is installed, total dilution ranges
from 10 to 35%.
- Minimum mining
widths have been applied in the various mining methods. The only
production style relevant to this constraint is 'narrow stoping' –
where the minimum width is set at 1.5m in a 17.0m sub level
interval.
- Mining operational
recovery for the underground mines is set at 85-100% due to the use
of remote loading units as well as paste filling activities. Mining
recovery is not inclusive of pillar loss – insitu mineralised
material between adjacent stope panels.
- Stope shape
dimensions vary between the various methods. Default hydraulic
radii (HR) are applied to each method and are derived either from
historical production or geotechnical reports / recommendations.
Where no data or exposure is available conservative HR values are
used based on the contact domain type.
- Mining sequence is
included in the mine scheduling process for determining the
economic evaluation and takes into account available operating time
and mining equipment size and performance.

Metallurgical
factors or
assumptions
|
- The metallurgical
process proposed and the appropriateness of that process to the
style of mineralisation.
- Whether the
metallurgical process is well-tested technology or novel in
nature.
- The nature, amount
and representativeness of metallurgical test work undertaken, the
nature of the metallurgical domaining applied and the corresponding
metallurgical recovery factors applied.
- Any assumptions or
allowances made for deleterious elements.
- The existence of
any bulk sample or pilot scale test work and the degree to which
such samples are considered representative of the orebody as a
whole.
- For minerals that
are defined by a specification, has the ore reserve estimation been
based on the appropriate mineralogy to meet the
specifications?
|
BHO
- A long history of
processing through several CIL processing existing facilities
demonstrates the appropriateness of the process to the styles of

CGO
- CGO has an existing
conventional CIL processing plant.
- The plant has a
nameplate capacity of 1.4Mtpa though this can be varied between
1.2- 1.6Mtpa pending rosters and material type.
- Gold extraction is
achieved using two staged crushing, ball milling with gravity
concentration and Carbon in Leach.
- Despite CGO having
a newly commissioned processing plant (2012/13 and subsequently
restarted in 2018) a high portion of the Ore Reserve mill feed have
extensive data when processed at other plants in the past 2-3
decades. This long history of processing demonstrates the
appropriateness of the process to the styles of mineralisation
considered.

capacity of 1.0Mtpa though this can be varied between 0.8-1.2Mtpa
pending rosters and material type.
- An extensive
database of historical CIL recoveries as well as detailed
metallurgical test work is available for the various deposits, and
these have been incorporated into the COG analysis and financial
models.
- For the Ore
Reserve, Plant recoveries of 93-95% have been utilised.

- Gold extraction is
achieved using staged crushing, ball milling with gravity
concentration and Carbon in Leach. The Higginsville plant has

- Additional
test-work is instigated where notable changes to geology and
mineralogy are identified. Small scale batch leach tests on primary
Louis ore have indicated lower recoveries (80%) associated with
finer gold and sulphide mineralisation.
- There have been no
major examples of deleterious elements affecting gold extraction
levels or bullion quality. Some minor variations in sulphide
mineralogy have had short-term impacts on reagent
consumptions.
- No bulk sample
testing is required whilst geology/mineralogy is consistent based
on treatment plant performance.

Classification
|
- The basis for the
classification of the Ore Reserves into varying confidence
categories.
- Whether the result
appropriately reflects the Competent Person's view of the
deposit.
- The proportion of
Probable Ore Reserves that have been derived from Measured Mineral
Resources (if any).
|
- The basis for
classification of the Mineral Resource into different categories is
made in accordance with the recommendations of the JORC Code 2012.
Measured Mineral Resources have a high level of confidence and are
generally defined in three dimensions with accurately defined or
normally mineralised developed exposure. Indicated Mineral
Resources have a slightly lower level of confidence but contain
substantial drilling and are in most instances capitally developed
or well defined from a mining perspective. Inferred Mineral
Resources always contain significant geological evidence of
existence and are drilled, but not to the same density. There is no
classification of any Mineral Resources that isn't drilled or
defined by substantial physical sampling works.
- Some Measured
Resources have been classified as Proven and some are defined as
Probable Ore Reserves based on internal judgement of the mining,
geotechnical, processing and or cost profile estimates.
- No Indicated
Mineral Resources material has been converted into Proven Ore
Reserve.
- The resultant Ore
Reserve classification appropriately reflects the view of the
Competent Person.
|
Audits or
reviews
|
- The results of any
audits or reviews of Ore Reserve estimates.
|
- Ore Reserves
inventories and the use of appropriate modifying factors are
reviewed internally on an annual basis.
- Additionally, mine
design and cost profiles are regularly reviewed by WGX operational
quarterly reviews.
- Financial auditing
processes, Dataroom reviews for asset sales / purchases and
stockbroker analysis regularly 'truth test' the assumptions made on
Ore Reserve designs and assumptions.
|
Discussion of
relative
accuracy/ confidence
|
- Where appropriate a
statement of the relative accuracy and confidence level in the Ore
Reserve estimate using an approach or procedure deemed appropriate
by the Competent Person. For example, the application of
statistical or geostatistical procedures to quantify the relative
accuracy of the reserve within stated confidence limits, or, if
such an approach is not deemed appropriate, a qualitative
discussion of the factors which could affect the relative accuracy
and confidence of the estimate.
- The statement
should specify whether it relates to global or local estimates,
and, if local, state the relevant tonnages, which should be
relevant to technical and economic evaluation. Documentation should
include assumptions made and the procedures used.
- Accuracy and
confidence discussions should extend to specific discussions of any
applied Modifying Factors that may have a material impact on Ore
Reserve viability, or for which there are remaining areas of
uncertainty at the current study stage.
- It is recognised
that this may not be possible or appropriate in all circumstances.
These statements of relative accuracy and confidence of the
estimate should be compared with production data, where
available.
|
- Whilst it should be
acknowledged that all Ore Reserves are based primarily upon an
estimate of contained insitu gold (the Mineral Resources Estimate),
it is the competent person's view that the consolidated Reserve
inventory is highly achievable in entirety.
- Given the entire
Ore Reserves inventory is within existing operations, with
budgetary style cost models and current contractual mining /
processing consumable rates, coupled with an extensive historical
knowledge / dataset of the Mineral Resources, it is the Competent
Person's view that the significant mining modifying factors (COGs,
geotechnical parameters and dilution ratio's) applied are
achievable and or within the limits of 10% sensitivity
analysis.

Appendix C – JORC 2012 Table 1– Nickel Division
SECTION 1: SAMPLING TECHNIQUES AND DATA
(Criteria in this section apply to all succeeding sections.)
Criteria
|
JORC Code
Explanation
|
Commentary
|
Sampling
techniques
|
- Nature and quality
of sampling (e.g. cut channels, random chips, or specific
specialised industry standard measurement tools appropriate to the
minerals under investigation, such as down hole gamma sondes, or
handheld XRF instruments, etc.). These examples should not be taken
as limiting the broad meaning of sampling.
- Include reference
to measures taken to ensure sample representivity and the
appropriate calibration of any measurement tools or systems
used.
- Aspects of the
determination of mineralisation that are Material to the Public
Report.
- In cases where
'industry standard' work has been done this would be relatively
simple (e.g. 'reverse circulation drilling was used to obtain 1 m
samples from which 3 kg was pulverised to produce a 30 g charge for
fire assay'). In other cases more explanation may be required, such
as where there is coarse gold that has inherent sampling problems.
Unusual commodities or mineralisation types (e.g. submarine
nodules) may warrant disclosure of detailed
information.
|
- Sampling of Ni is
almost exclusively from diamond core drilling completed from
underground platforms. Historical surface RC samples (completed by
WMC) intersect the mineralisation. HMR Drilling Services has
carried out underground diamond drilling at Beta Hunt since 2016
and are currently utilising a fleet of Erebus M90 mobile
underground diamond core rigs. Sampling is highly selective
according to the visual nickel mineralisation observed by the
geologist. Generally, sampling is between 0.1m to 1.2m intervals,
though some historical sample intervals are noted to
0.06m.
- Diamond drill core
is logged on site by geologists for lithology, alteration,
mineralisation, and structures. Structural measurements, alpha and
beta angles are taken on major lithological contacts, foliations,
veins, and major fault zones. Multiple specific gravity ("SG")
measurements are taken per hole in both ore and waste zones. Field
geotechnicians record the Rock Quality Designation ("RQD") measure
for every second drill hole. All drill holes are digitally
photographed.
- NQ2 drill holes
designated as resource definition or exploration are cut in half
with the top half of the core sent to the laboratory for analysis
and the other half placed back in the core tray. This is then
transferred onto pallets and moved to the core yard library. All
grade control drilling is sampled as whole core samples with a
maximum 1m interval.
|
Drilling
techniques
|
- Drill type (e.g.
core, reverse circulation, open-hole hammer, rotary air blast,
auger, Bangka, sonic, etc.) and details (e.g. core diameter, triple
or standard tube, depth of diamond tails, face-sampling bit or
other type, whether core is oriented and if so, by what method,
etc.).
|
- Drilling for Ni has
been completed at the deposit from 1974 to the present by various
companies and utilised predominantly diamond drilling of NQ2
diameter. All diamond core was oriented, as far as possible, and
oriented structures logged with alpha and beta angles. During the
drilling process the drillers mark on the end of each drill run the
'bottom of hole position' using a red chinagraph pencil. This
orientation mark forms the basis for orientating the drill core.
Orientation marks are usually placed at every 3m or 6m intervals
and correspond with the driller's run. A driller's run is marked by
a core block at the end of the run, the last piece of core before
each block will have the orientation mark on it. Electronic
orientation tools were used sporadically in 2018 and
2021/2022.
|
Drill sample
recovery
|
- Method of recording
and assessing core and chip sample recoveries and results
assessed.
- Measures taken to
maximise sample recovery and ensure representative nature of the
samples.
- Whether a
relationship exists between sample recovery and grade and whether
sample bias may have occurred due to preferential loss/gain of
fine/coarse material.
|
- Historical and
current practice ensures all diamond core intervals are measured
and recorded for rock quality designation (RQD) and core loss. Core
blocks are utilised and placed at 1m core runs in the core trays.
The average core recovery at the deposit is routinely
>95%.
- Drill rigs are
supervised by company geologists to ensure adequate sample returns
are being maintained.
- No bias has been
observed between sample recovery and grade.
|
Logging
|
- Whether core and
chip samples have been geologically and geotechnically logged to a
level of detail to support appropriate Mineral Resource estimation,
mining studies and metallurgical studies.
- Whether logging is
qualitative or quantitative in nature. Core (or costean, channel,
etc.) photography.
- The total length
and percentage of the relevant intersections logged

underground drill-holes are logged in detail for geology, veining,
alteration, mineralisation and structure. Core has been logged in
enough detail to allow for the relevant mineral resource estimation
techniques to be employed.
- Core is
photographed both wet and dry. All photos are stored on the
Company's servers, with the photographs from each hole contained
within separate folders.
- Development faces
are mapped geologically.
- Logging is both
quantitative and qualitative in nature.
- All holes are
logged completely, all faces are mapped completely.
|
Sub-sampling
techniques
and sample preparation
|
- If core, whether
cut or sawn and whether quarter, half or all core
taken.
- If non-core,
whether riffled, tube sampled, rotary split, etc. and whether
sampled wet or dry.
- For all sample
types, the nature, quality and appropriateness of the sample
preparation technique.
- Quality control
procedures adopted for all sub-sampling stages to maximise
representivity of samples.
- Measures taken to
ensure that the sampling is representative of the in-situ material
collected, including for instance results for field
duplicate/second-half sampling.
- Whether sample
sizes are appropriate to the grain size of the material being
sampled.
|
- Diamond holes
designated as resource definition or exploration are cut in half
using a core saw, with the top half of the core sent to the
laboratory for analysis and the other half placed back in the core
tray. This is then transferred onto pallets and moved to the core
yard library. All grade control drilling is sampled as whole core
samples with a maximum 1m interval.
- Sample preparation
has been completed by SGS laboratory at either Perth or Kalgoorlie
facilities since 2016. Samples were dried and then crushed to 3mm
and then split to generate samples between 1kg to 2.8kg. One split
is forwarded to milling where it is pulverised to 90% passing 75um,
the second split is retained as a crushed sample.
- Laboratory internal
QA standards include replicates, split samples, and blanks which
are randomly added to job batches.
- The sample size is
considered appropriate for the grain size of the material being
sampled.
|
Quality of assay
data and
laboratory tests
|
- The nature, quality
and appropriateness of the assaying and laboratory procedures used
and whether the technique is considered partial or
total.
- For geophysical
tools, spectrometers, handheld XRF instruments, etc., the
parameters used in determining the analysis including instrument
make and model, reading times, calibrations factors applied and
their derivation, etc.
- Nature of quality
control procedures adopted (e.g. standards, blanks, duplicates,
external laboratory checks) and whether acceptable levels of
accuracy (i.e. lack of bias) and precision have been
established.
|
- Prior to March 2016
nickel samples were analysed at Bureau Veritas Laboratory
(KalAssay). A 0.2g subsample was digested using a mixed acid before
ICP analysis. Post 2016, analyses have been completed by SGS
Laboratory in Perth where a 0.2g subsample of pulverised material
is taken for ICP 4 acid digest and final analysis using ICP-OES.
This process is considered appropriate. The acid digest is with
nitric, hydrochloric, hydrofluoric, and perchloric acids to effect
as near total solubility of the sample as possible.
- QA/QC processes are
controlled by written procedures and includes the use of certified
reference materials and coarse blanks.
- Certified Standards
for gold and nickel were provided by Ore Research & Exploration
Pty Ltd ("OREAS") between 2014 and June 2016. Geostats Ni purpose
reference standard samples were introduced in June 2020 and
effectively replaced the OREAS reference samples. Coarse blank is
Bunbury Basalt sourced from Gannet Holdings Pty Ltd.
- No significant
QA/QC issues have arisen in recent drilling results. Routine audit
visits to the laboratories are completed by senior geology
personnel.
|
Verification of
sampling and
assaying
|
- The verification of
significant intersections by either independent or alternative
company personnel.
- The use of twinned
holes.
- Documentation of
primary data, data entry procedures, data verification, data
storage (physical and electronic) protocols.
- Discuss any
adjustment to assay data.
|
- Significant assay
results are verified by senior geologists through visual inspection
of retained core (or viewing core photos where whole core was
submitted for assay). If significant intersections are not
supported by visual checks, samples are re-assayed to confirm
original results.
- Nickel lenses are
defined by close spaced grade control drilling so twinned holes are
not require.
- Primary data is
collected utilising LogChief. The information is imported into a
SQL database server and verified.
- All data used in
the calculation of resources and reserves are compiled in databases
which are overseen and validated by Senior Geologists.
- No adjustments have
been made to any assay data.
|
Location of data
points
|
- Accuracy and
quality of surveys used to locate drill holes (collar and down-hole
surveys), trenches, mine workings and other locations used in
Mineral Resource estimation.
-
- Specification of
the grid system used.
- Quality and
adequacy of topographic control.
|
- Drill collars were
historically surveyed by the mine survey department using
electronic total station equipment. Single shot downhole
survey measurements are taken at 15m and 30m, then every 30m
thereafter. Multi-shot surveys are conducted at the completion of
each hole at 3m intervals. During 2023, UG holes utilise a DeviGyro
OX tool to eliminate magnetic interference. This method has been
used for surface drilling since 2021. The Gyro recordings are
coupled with cloud based systems to facilitate electronic loading
directly into the database eliminating manual entry.
- All drilling and
resource estimation is preferentially undertaken in local Mine
Grid.
- Topographic control
is generated from a combination of remote sensing methods and
ground-based surveys. This methodology is adequate for the
resources in question.
|
Data spacing and
distribution
|
- Data spacing for
reporting of Exploration Results.
- Whether the data
spacing and distribution is sufficient to establish the degree of
geological and grade continuity appropriate for the Mineral
Resource and Ore Reserve estimation procedure(s) and
classifications applied.
- Whether sample
compositing has been applied.
|
- The structural
complexity of nickel mineralisation at Beta Hunt is reflected by
closer spaced drill patterns. Nickel Mineral Resources are based on
an initial 30m by 30m down to 10m x 10m spaced drill hole pattern.
Subsequent drilling focuses on stepping out from a significant
intercept to define any attenuated pinch out, basalt roll-over or
fault offsetting the nickel mineralisation.
- The data spacing
and distribution is sufficient to establish geological and grade
continuity appropriate to the classification applied. The nickel
lenses are highly visible and underground mapping confirms lens
geometry and extent.
- Sampling of core
varies between 0.2m to 1.2m or to geological contacts. Samples are
not composited when submitted for analysis. Sample compositing (to
0.7m or 0.8m) was applied at Kappa and Delta lenses for estimation.
All other nickel lenses utilised an 2D linear accumulation variable
composited as a single full zone intercept.
|
Orientation of data
in
relation to geological
structure
|
- Whether the
orientation of sampling achieves unbiased sampling of possible
structures and the extent to which this is known, considering the
deposit type.
- If the relationship
between the drilling orientation and the orientation of key
mineralised structures is considered to have introduced a sampling
bias, this should be assessed and reported if material.
|
- Drilling
intersections are nominally designed to be normal to the nickel
lens as far as underground infrastructure constraints allow. Visual
observation of the flat lying lens geometry during air leg mining
verifies the sample orientation is effective.
- It is not
considered that drilling orientation has introduced an appreciable
sampling bias.
|
Sample
security
|
- The measures taken
to ensure sample security.
|
- Sample security
protocols in place aim to maintain the chain of custody of samples
to prevent inadvertent contamination or mixing of samples, and to
render active tampering as difficult as possible. Sampling is
conducted by Westgold staff or contract employees under the
supervision of site geologists. The work area and sample storage
areas are covered by general site security video surveillance.
Samples bagged in plastic sacks are collected by the laboratory
transport contractor and driven to the Perth or Kalgoorlie
laboratories.
|
Audits or
reviews
|
- The results of any
audits or reviews of sampling techniques and data
|
- Site generated
resources and reserves and the parent geological data is routinely
reviewed by the Westgold Corporate technical team. Routine visits
to the certified laboratories are completed by senior
personnel.

Exploration done by
other
parties
|
- Acknowledgment and
appraisal of exploration by other parties
|
- Western Mining
Corporation (WMC) first intersected nickel sulphide mineralisation
at Red Hill in January 1966 after drilling to test a gossan outcrop
grading 1% Ni and 0.3% Cu. This discovery led to delineation of the
Kambalda Nickel Field where WMC identified 24 deposits hosted in
structures that include the Kambalda Dome, Widgiemooltha Dome and
Golden Ridge Greenstone Belt. The Hunt nickel deposit was
discovered by WMC in March 1970, during routine traverse drilling
over the south end of the Kambalda Dome. The discovery hole, KD262,
intersected 2.0m grading 6.98% Ni. Portal excavation for a decline
access began in June 1973. While the decline was being developed,
the Hunt orebody was accessed from the neighbouring Silver Lake
mine, via a 1.15km cross-cut on 700 level.
- Westgold work has
generally confirmed the veracity of historic exploration
data.
|
Geology
|
- Deposit type,
geological setting and style of mineralisation.
|
- The Kambalda–St
Ives region forms part of the Norseman–Wiluna greenstone belt which
comprises regionally extensive volcano-sedimentary packages. These
were extruded and deposited in an extensional environment at about
2,700–2,660 Ma. The mining district is underlain by a
north-northwest trending corridor of basalt and komatiite rocks
termed the Kambalda Dome. The iron-nickel mineralisation is
normally accumulated within the thick Silver Lake Member of the
Kambalda Komatiite Formation above, or on the contact with the dome
structured Lunnon Basalt.
- Nickel
mineralisation is hosted by talc-carbonate and serpentine altered
ultramafic rocks. The deposits are ribbon-like bodies of massive,
matrix and disseminated sulphides varying from 0.5 m to 4.0m in
true thickness but averaging between 1.0 m and 2.0 m. Down dip
widths range from 40m to 100m, and the grade of nickel ranges from
below 1% to 20%. Major minerals in the massive and disseminated
ores are pyrrhotite, pentlandite, pyrite, chalcopyrite, magnetite
and chromite, with rare millerite and heazlewoodite generally
confined to disseminated mineralisation. The hangingwall
mineralisation tends to be higher tenor than the contact material.
The range of massive ore grades in the hangingwall is between 10%
Ni and 20% Ni while the range for contact ore is between 9% Ni and
12% Ni. The hangingwall mineralogy varies between an
antigorite/chlorite to a talc/magnesite assemblage. The basalt
mineralogy appears to conform to the amphibole, chlorite,
plagioclase plus or minus biotite.
- Unlike other nickel
deposits on the Kambalda Dome, the Beta Hunt system displays
complex contact morphologies, which leads to irregular ore
positions. The overall plunge of the deposits is shallow in a
southeast direction, with an overall plunge length in excess of
1km. The individual lode positions have a strike length averaging
40m and a dip extent averaging 10m. The geometry of these lode
positions vary in dip from 10° to the west to 80° to the east. The
mineralisation within these lode positions is highly variable
ranging from a completely barren contact to zones where the
mineralisation is in excess of 10m in true thickness.
- The Hunt and Lunnon
shoots are separated from the Beta and East Alpha deposits by the
Alpha Island Fault. Hunt and Beta both occur on the moderately
dipping western limb of the Kambalda Dome and are thought to be
analogous. Similarly, Lunnon and East Alpha occur on the steeply
dipping eastern limb of the dome and also have similar
characteristics.
|
Drill hole
Information
|
- A summary of all
information material to the understanding of the exploration
results including a tabulation of the following information for all
Material drill holes:
- easting and
northing of the drill hole collar
- elevation or RL
(Reduced Level – elevation above sea level in metres) of the drill
hole collar
- dip and azimuth of
the hole
- down hole length
and interception depth
- hole
length.
- If the exclusion of
this information is justified on the basis that the information is
not Material and this exclusion does not detract from the
understanding of the report, the Competent Person should clearly
explain why this is the case.
|
- Exploration results
are not being reported in this release.
|
Data aggregation
methods
|
- In reporting
Exploration Results, weighting averaging techniques, maximum and/or
minimum grade truncations (e.g., cutting of high grades) and
cut-off grades are usually Material and should be
stated.
- Where aggregate
intercepts incorporate short lengths of high-grade results and
longer lengths of low-grade results, the procedure used for such
aggregation should be stated and some typical examples of such
aggregations should be shown in detail.
- The assumptions
used for any reporting of metal equivalent values should be clearly
stated.
|
- Exploration results
are not being reported in this release.
|
Relationship
between
mineralisation widths and
intercept lengths
|
- These relationships
are particularly important in the reporting of Exploration
Results.
- If the geometry of
the mineralisation with respect to the drill hole angle is known,
its nature should be reported.
- If it is not known
and only the down hole lengths are reported, there should be a
clear statement to this effect (e.g., 'down hole length, true width
not known').
|
- Exploration results
are not being reported in this release.
|
Diagrams
|
- Appropriate maps
and sections (with scales) and tabulations of intercepts should be
included for any significant discovery being reported These should
include, but not be limited to a plan view of drill hole collar
locations and appropriate sectional views.
|
- Exploration results
are not being reported in this release.
|
Balanced
reporting
|
- Where comprehensive
reporting of all Exploration Results is not practicable,
representative reporting of both low and high grades and/or widths
should be practiced to avoid misleading reporting of Exploration
Results.
|
- Exploration results
are not being reported in this release.
|
Other
substantive
exploration data
|
- Other exploration
data, if meaningful and material, should be reported including (but
not limited to): geological observations; geophysical survey
results; geochemical survey results; bulk samples – size and method
of treatment; metallurgical test results; bulk density,
groundwater, geotechnical and rock characteristics; potential
deleterious or contaminating substances.
|
- Exploration results
are not being reported in this release.
|
Further

- The nature and
scale of planned further work (e.g. tests for lateral extensions or
depth extensions or large-scale step-out drilling).
- Diagrams clearly
highlighting the areas of possible extensions, including the main
geological interpretations and future drilling areas, provided this
information is not commercially sensitive.
|
- Ongoing underground
exploration activities will be undertaken to support continuing
mining activities at Westgold Gold Operations.

Database
integrity
|
- Measures taken to
ensure that data has not been corrupted by, for example,
transcription or keying errors, between its initial collection and
its use for Mineral Resource estimation purposes.
- Data validation
procedures used.
|
- The database used
for the estimation was extracted from the Westgold's DataShed
database management system stored on a secure SQL
server.
- As new data is
acquired it passes through a validation approval system designed to
pick up any significant errors before the information is loaded

visits undertaken by the Competent Person and the outcome of those
visits.
- If no site visits

|
Geological
interpretation
|
- Confidence in (or
conversely, the uncertainty of) the geological interpretation of
the mineral deposit.
- Nature of the data
used and of any assumptions made.
- The effect, if any,
of alternative interpretations on Mineral Resource
estimation.
- The use of geology
in guiding and controlling Mineral Resource estimation.
- The factors
affecting continuity both of grade and geology.
|
- Confidence in the
interpretations is high as the Ni sulphides have been mined since
1974 and the structural setting is well understood. Mineralisation
is hosted within and adjacent to volcanic channels that sit at the
stratigraphic base of the Kambalda Komatiite. Nickel sulphides are
within narrow troughs that plunge gently to the south.
- The mineralisation
was interpreted using diamond core drilled primarily from
underground locations
- The current
interpretations have been visually validated through underground
mining so alternative interpretations are not considered
viable.
- Geological logging
of the ultramafic / basalt contact, and the visible Ni sulphides is
used to define the mineralisation wireframes used in the Mineral
Resource estimation.
- Geological matrixes
were established to assist with interpretation and construction of
the estimation domains.
- The Ni deposits
occur within troughs on both the east and west limbs of the
Kambalda Dome. The deposits are ribbon-like bodies of massive,
matrix and disseminated sulphides that occur at the base of the
silver Lake Member on the contact with the Lunnon Basalt. The
massive and disseminated lodes tend to be higher tenor than the
contact material.
|
Dimensions
|
- The extent and
variability of the Mineral Resource expressed as length (along
strike or otherwise), plan width, and depth below surface to the
upper and lower limits of the Mineral Resource.
|
- Unlike other nickel
deposits on the Kambalda Dome, the Beta Hunt system displays
complex contact morphologies, which leads to irregular lode
positions. The overall plunge of the deposits is shallow in a
southeast direction, with an overall plunge length in excess of
1km. The individual lode positions have a strike length averaging
40m and a dip extent averaging 10m. The geometry of these lode
positions varies in dip from 10° to the west to 80° to the east.
The mineralisation within these lode positions is highly variable
ranging from a completely barren contact to zones where the
mineralisation is in excess of 10m in true thickness. The Ni
deposits predominantly vary from 0.5m to 4m true thickness but
average between 1m and 2m. Down dip widths range from 40m to 100m.
The depth at which the Ni mineralisation occurs along the UM/Basalt
contact varies from approximately 650m to 820m in depth from
surface.
|
Estimation and
modelling techniques.
|
- The nature and
appropriateness of the estimation technique(s) applied and key
assumptions, including treatment of extreme grade values,
domaining, interpolation parameters, maximum distance of
extrapolation from data points.
- The availability of
check estimates, previous estimates and/or mine production records
and whether the Mineral Resource estimate takes appropriate account
of such data.
- The assumptions
made regarding recovery of by-products.
- Estimation of
deleterious elements or other non-grade variables of economic
significance (e.g. sulphur for acid mine drainage
characterisation).
- In the case of
block model interpolation, the block size in relation to the
average sample spacing and the search employed.
- Any assumptions
behind modelling of selective mining units.
- Any assumptions
about correlation between variables.
- The process of
validation, the checking process used, the comparison of model data
to drillhole data, and use of reconciliation data if
available.
|
- The Ni sulphides
display lenticular geometries and are concentrated along linear
channels that overlie gold-bearing shears in the Lunnon Basalt. The
process of modelling the mineralised lenses involved a review of
the ultramafic contact while stepping through the drill data and
digitising polygons to suit the geometry of the nickel sulphides on
each section. Sections were orientated perpendicular to the strike
of the mineralisation and separated by distances to suit the
spacing of fans of drill holes and locations of structurally
related disruptions in the continuity of the geology. Numerous
porphyry dykes of varying composition from granite through to
diorite and granodiorite break up the nickel mineralisation and
effectively stope out the nickel-bearing sulphides. The interpreted
lenses are modelled to account for the porphyry intrusions so that
mineralisation does not extend into areas of waste. Mineralisation
domains were identified using geological characteristics (logged
nickel sulphides ranging from massive to matrix and blebby), and
intervals within interpreted domains captured the full sequence of
economic nickel sulphide profile (from the massive sulphide through
matrix and included blebby sulphides).
- While each of the
nickel sulphide deposits and each mineralised body was estimated
individually, the deposits were subdivided into domains for
geostatistical purposes. The domains were defined visually such
that logically grouped lenses tend to have common stratigraphic
positions and mineralisation characteristics and do not overlap in
space. Drillhole samples were flagged with the mineralisation
wireframes. Top-cuts were applied to high grade outliers for Au,
As, and Cu within each grouped domain by analysing log probability
plots, histograms, and mean/variance plots.
- Estimations was
completed for Ni, Au, As, Co, Cu, Fe, MgO, S, and
density.
- Variograms were
modelled on the accumulation "metal" variable (vertical thickness
multiplied by grades) for all elements, using the intermediate
stage 1 m composite data. Micromine software was used for
geostatistical analysis. For Kappa and Delta, variograms were
modelled using the 0.8m or 0.7m composites for the various elements
within each domain, using Supervisor software.
- Three-dimensional,
non-rotated block volume models were created for use in grade
estimation and sized to encompass each of the nickel sulphide
deposits. No waste background model was created. The models assume
underground mining by very selective methods, using airleg miners
where required. As the lodes are very narrow, usually averaging
less than 2m horizontal width, it would be unlikely that selective
mining would occur across their width. Therefore, a seam model was
chosen to represent their volume. For the relatively flat-lying
deposits, a single block spans the vertical (Z) width of the
zones.
- The selection of
appropriate block sizes took into consideration the geometry of the
domains to be modelled, the local drillhole spacing and the strike
and dip of the domains. The narrow lode domains had parent cell
dimensions set to 10m x 10m in the northing and easting directions
for all modelled lenses. The dimensions across the width of the
lenses are infinitely variable in vertical direction to allow for
accurate definition of the variable width in each lens using a
single cell. For the Kappa and Delta lenses, a parent block size
was set to 2m (X) by 5m (Y) by 5m (Z) with sub-celling to 0.5m (X)
by 1.25 (Y) by 1.25m (Z).
- Lode geometries are
generally very narrow. For this reason, an estimation methodology
using two-dimensional linear accumulation was selected for
estimation of each mineralised lode. The zone samples were
composited to single, full zone width intercepts having variable
lengths according to the width of the mineralisation and angle of
intersection. Composited full zone intercept widths do not
necessarily represent the true widths of the mineralised zones. To
calculate true and vertical widths, local orientations (dip and dip
direction) of the mineralisation were assigned to the composite
intervals based on the mineralisation wireframes. Dip and dip
direction values were calculated for each triangle in the wireframe
models, and then interpolated into the sample points using the
nearest neighbour ("NN") method. From this, the composite
interval's true thickness, vertical thickness and horizontal
thickness were calculated and visually checked. Accumulation
variables were calculated for each modelled element. Two lenses at
the East Alpha deposit were modelled using 3D wireframes and
ordinary kriging interpolation using 0.8m composites (Kappa) and
0.7m (Delta).
- For all Ni
deposits, except the Kappa and Delta lenses, a base search ellipse
equal to the long ranges for each deposit was used. The first
search ellipse employed two-thirds of the base search parameters.
The second and all the subsequent interpolation runs used a search
ellipse multiplier to the search axes, which was started from 1 and
incremented by 1 until all cells were informed with all estimated
grades. All accumulations and vertical thicknesses were initially
estimated in all sub-cells, and then volume weighted average values
were calculated within the 10m x 10m parent cells. When model cells
were estimated using search radii that were not greater than twice
the long ranges along the horizontal axes, the minimum and maximum
composite search parameters for block estimates used a minimum of
four and a maximum of six samples. No restrictions were applied for
drillhole numbers used in the estimate as all samples were
composited to the entire mineralised intersections. No sectors were
employed. The degree of discretization was 5 x 5 x 5 points. The
grade estimation in the centre of the block consisted of the simple
average value of the estimated points throughout the block
volume.
- For the Kappa and
Delta lenses, a single estimation pass was used with a search
distance set to 50m and the search ellipse orientated along the
geometry of the lode. Discretisation was set to 4 x 5 x 5 (XYZ). A
minimum of 5 samples and maximum of 15 was applied.
- A correlation
exists between Ni and density, and this was used to calculate
regression formulae for estimation which were then applied to all
composited intervals. The resultant estimated density values were
interpolated into the block model using ordinary kriging algorithm
and semi variogram models generated for nickel grades. No bulk
density data was available for Beta Central. A regression formula
was generated for combined composites at B30, B40, and Gamma, and a
formula derived for the Beta West and East Alpha
composites.
- The Mineral
Resource is depleted for mining voids and subsequently classified
in line with JORC guidelines utilising a combination of various
estimation derived parameters and geological / mining
knowledge.
- Model validation of
grade estimates was completed by visual checks on screen in
cross-section and plan view to ensure that block model grades
honoured the grade of the composites. A statistical comparison of
sample vs block grades was tabulated and swath plots generated in
various directions. Model performance is measured against end of
month reconciliations.
|
Moisture
|
- Whether the
tonnages are estimated on a dry basis or with natural moisture, and
the method of determination of the moisture content.
|
- Tonnage estimates
are dry tonnes.
|
Cut-off
parameters
|
- The basis of the
adopted cut-off grade(s) or quality parameters applied.
|
- The Ni Mineral
Resource is reported within proximity to underground development
and nominal 1% Ni lower cut-off grade for the nickel sulphide
mineralisation.
|
Mining factors
or
assumptions
|
- Assumptions made
regarding possible mining methods, minimum mining dimensions and
internal (or, if applicable, external) mining dilution. It is
always necessary as part of the process of determining reasonable
prospects for eventual economic extraction to consider potential
mining methods, but the assumptions made regarding mining methods
and parameters when estimating Mineral Resources may not always be
rigorous. Where this is the case, this should be reported with an
explanation of the basis of the mining assumptions
made.
|
- Beta Hunt is an
underground mine accessed from established portals and declines.
The mine commenced operation in 1974, mining both nickel and gold
over extended periods. Mining is via flat back or air leg utilising
single boom jumbo and air leg miner. Flat back mining operates on
top of waste fill placed on the previous level. Approximately 0.5m
of waste in the floor is removed on completion of mining to ensure
full recovery of the nickel.
- No mining dilution
or ore loss has been modelled in the resource model or applied to
the reported Mineral Resource.
|
Metallurgical
factors or
assumptions
|
- The basis for
assumptions or predictions regarding metallurgical amenability. It
is always necessary as part of the process of determining
reasonable prospects for eventual economic extraction to consider
potential metallurgical methods, but the assumptions regarding
metallurgical treatment processes and parameters made when
reporting Mineral Resources may not always be rigorous. Where this
is the case, this should be reported with an explanation of the
basis of the metallurgical assumptions made.
|
- Nickel
mineralisation processing is covered by the Ore Tolling and
Concentrate Purchase Agreement (OTCPA) with BHP. Material is
blended with nickel ores from other mines, and the metallurgical
recovery credited to Beta Hunt is based on the mineralisation
grade. The Kambalda Nickel Concentrator (KNC) is the delivery point
for Beta Hunt ore under the OTCPA.
|
Environmental
factors or
assumptions
|
- Assumptions made
regarding possible waste and process residue disposal options. It
is always necessary as part of the process of determining
reasonable prospects for eventual economic extraction to consider
the potential environmental impacts of the mining and processing
operation. While at this stage the determination of potential
environmental impacts, particularly for a greenfields project, may
not always be well advanced, the status of early consideration of
these potential environmental impacts should be reported. Where
these aspects have not been considered this should be reported with
an explanation of the environmental assumptions made.
|
- Westgold operates
in accordance with all environmental conditions set down as
conditions for grant of the respective leases. Beta Hunt is an
operating underground mine that is in possession of all required
permits. Westgold owns and operates Beta Hunt through a sub-lease
agreement with SIGMC. The environmental permitting and compliance
requirements for mining operations on the sub-lease tenements are
the responsibility of Westgold under the sub-lease
arrangement.
|
Bulk
density
|
- Whether assumed or
determined. If assumed, the basis for the assumptions. If
determined, the method used, whether wet or dry, the frequency of
the measurements, the nature, size and representativeness of the
samples.
- The bulk density
for bulk material must have been measured by methods that
adequately account for void spaces (vugs, porosity, etc.), moisture
and differences between rock and alteration zones within the
deposit.
- Discuss assumptions
for bulk density estimates used in the evaluation process of the
different materials.
|
- A large suite of
bulk density determinations has been carried out across the project
areas. All raw sample intervals within the mineralised zones that
had both Ni grades and density measurements were used to calculate
regression formulae which were then applied to all composited
intervals. The resultant estimated density values were interpolated
into the block model using ordinary kriging algorithm and semi
variogram models generated for nickel grades.
- A significant past
mining history has validated the assumptions made surrounding bulk
density.
|
Classification
|
- The basis for the
classification of the Mineral Resources into varying confidence
categories.
- Whether appropriate
account has been taken of all relevant factors (i.e. relative
confidence in tonnage/grade estimations, reliability of input data,
confidence in continuity of geology and metal values, quality,
quantity and distribution of the data).
- Whether the result
appropriately reflects the Competent Person's view of the
deposit.
|
- Mineral Resources
are classified in line with JORC guidelines utilising a combination
of various estimation derived parameters, input data and geological
/ mining knowledge.
- This approach
considers all relevant factors and reflects the Competent Person's
view of the deposit.
|
Audits or
reviews
|
- The results of any
audits or reviews of Mineral Resource estimates.
|
- Resource estimates
are peer reviewed by the Corporate technical team.
|
Discussion of
relative
accuracy/ confidence
|
- Where appropriate a
statement of the relative accuracy and confidence level in the
Mineral Resource estimate using an approach or procedure deemed
appropriate by the Competent Person. For example, the application
of statistical or geostatistical procedures to quantify the
relative accuracy of the resource within stated confidence limits,
or, if such an approach is not deemed appropriate, a qualitative
discussion of the factors that could affect the relative accuracy
and confidence of the estimate.
- The statement
should specify whether it relates to global or local estimates,
and, if local, state the relevant tonnages, which should be
relevant to technical and economic evaluation. Documentation should
include assumptions made and the procedures used.
- These statements of
relative accuracy and confidence of the estimate should be compared
with production data, where available.
|
- The high quality of
input data, and robust knowledge of the structural emplacement of
Ni at Beta Hunt provides confidence in the Mineral Resource
estimate. Ni lenses are mined via air leg which provides
flexibility for mining diverse geometries which are highly visible.
All currently reported resources estimates are representative on
both a global and local scale.
- A continuing
history of mining with good reconciliation of mine claimed to mill
recovered provides confidence in the accuracy of the
estimates.
