Scallywag Exploration Results
Prospectivity of targets confirmed
Significant gold and multi-element geochemical anomalism
detected
H igh-grade silver and copper mineralisation intersected
THIS ANNOUNCEMENT CONTAINS INSIDE INFORMATION AS STIPULATED
UNDER THE UK MARKET ABUSE REGULATIONS. ON PUBLICATION OF THIS
ANNOUNCEMENT VIA A REGULATORY INFORMATION SERVICE, THIS INFORMATION
IS CONSIDERED TO BE IN THE PUBLIC DOMAIN .
Greatland Gold plc (AIM:GGP; Greatland or Company) is pleased to
announce the results of its 2022 exploration programme at its
100%-owned Scallywag project in the Paterson region of Western
Australia. Scallywag is located adjacent to Greatland's flagship
Havieron gold-copper project which the Company discovered in
2018.
Highlights
-- Hole A35RD001 targeting the A35 Prospect conductor
intersected 2m @ 2.04g/t Au from 70m, within a mineralised gold
halo of 12m @ 0.48g/t Au from 69m noting that the interval contains
wet samples and immediately precedes a missing sample.
Significantly, anomalous bismuth and other pathfinder geochemistry
is associated with the intersection
-- Anomalous gold, strong silver and copper plus pathfinders
identified while testing a conductor at the Pearl prospect
(PPDD003) include:
- 1m @ 1,364g/t Ag and 0.35% Cu from 76m (remains open at depth)
- 1m @ 0.76g/t Au and 109ppm Bi from 251m
- 1m @ 0.1% Cu and 22.6ppm Bi from 418m
- 1m @ 50.9ppm Bi from 65m
-- These results came as a result of a ground electromagnetic
(EM) survey (follow up on the 2021 programme) which confirmed and
refined several EM conductor targets, testing of which commenced
with reverse circulation (RC) pre-collar and diamond core
drilling
Greatland Managing Director, Shaun Day, commented:
"Our recent exploration campaign at Scallywag has delivered the
most encouraging results to date."
"At the A35 Prospect, pre-collar drilling was completed with
gold mineralisation intercepted plus important pathfinder
geochemistry encountered, including bismuth which is associated
with the Havieron and Telfer gold-copper deposits. The high-grade
silver and copper mineralisation intercepted at the Pearl Prospect,
confirms the possibility of a new style of deposit being
identified. The underlying deeper geophysical targets at both
prospects are yet to be tested but have now been prioritised for
diamond drilling in 2023."
"These results, together with the continual improvement in
understanding of the buried geology, stratigraphy and structure,
increase our confidence in the prospectivity of the ground, and our
ability to vector towards intrusion related and other styles of
mineralised systems at Scallywag."
Overview of the 2022 Scallywag Programme.
Exploration work in 2022 focused on drill testing prospects and
anomalies defined from previous ground EM and drilling programmes
(see RNS Announcement titled "Results from the 2021 Exploration
Programme at Scallywag" dated 5 April 2022).
A specialised RC rig was used to drill pre-collars ahead of
completing the holes with a diamond rig with the aim of improving
result turnarounds. A total of eight RC pre-collar holes for 1,238m
and one diamond hole with a total depth of 488.6m, for a total of
1,726.6m, were completed (see Table 1 and Figure 1 below).

Figure 1. Ground EM, Drilling and targets
The approach to drilling was influenced by unexpectedly high
water inflows in some areas, limiting the achievable depth of the
pre-collars. The diamond rig became available late in the field
season after completing other priorities, resulting in only one
hole (PDD003) completed at Scallywag. Completion of the remainder
of the RC pre-collars with diamond tails is planned for 2023 as is
follow up drilling based on the latest results.
Pearl Prospect
Following ground EM geophysical surveys, refined EM conductor
targets were generated at the Pearl prospect during the start of
the field season. In addition to drilling two RC pre-collars to
test the plate targets defined during 2021, an additional hole was
diamond drilled from surface (being PDD003) targeting a newly
identified high priority EM conductor.
Drilling intersected fine-grained, silty sandstone sediments
with zones of variably intense calcareous sandstones. A zone of
high water inflow and extremely broken ground, thought to be a
major fault or shear structure, was intersected. No sample was able
to be collected between 77m and 151m downhole, as a mud-rotary
method was required to advance the hole due to challenging ground
conditions.
Several small metallic chips with native copper and chalcopyrite
were collected from the rubbly core at around 76 - 77m, immediately
before the area of maximum broken ground and no sample returned.
Initial portable X-ray fluorescence (PXRF) analysis showed readings
up to 17% copper, with highly anomalous silver and tungsten. Any
interpretation as to the origin and nature of these metallic
fragments would be highly speculative given the nature of the
sampling.
Subsequent laboratory assays revealed multiple instances of
anomalous precious and base metals (see Table 2 and Figure 2)
including:
-- 1m @ 1,364g/t Ag and 0.36% Cu from 76m
-- 1m @ 0.76g/t Au with a 109ppm Bi from 251m
-- 1m @ 0.11% Cu from 418m
-- 1m @ 50.9ppm Bi from 65m

Table 2. Significant assays from Scallywag drilling
Interestingly, the high copper-silver assay interval comes from
the final recovered sample before drilling conditions forced
mud-rotary drilling. The poor drilling conditions are likely due to
a significant structure being intersected in the hole. From the
assay results at the top of the structure it is likely that this
large structure is mineralised. Mineralised shear zones are hosts
to many ore bodies in Australia and globally. Greatland is
intending to re-drill at least part of the unsampled hole interval
during its 2023 program. This will enable the Company to complete
the geological picture and more fully understand the highly
encouraging metal values in the PXRF reading and lab assays.
A35 Prospect
At the A35 Prospect, three RC pre-collars were drilled to target
the deep interpreted EM conductor plates. Assay results for
A35RD001 returned a significant gold intersection of 12m @ 0.48g/t
Au from 69m, including 2m @ 2.04g/t Au from 70m, in the weathered
profile, with associated geochemical pathfinder element anomalism
(see Table 2). It must be noted that the hole was also affected by
water inflows and the majority of samples from the mineralised zone
from around 68m to 86m downhole were wet or moist and there was
potentially downhole smearing of the high gold grades. No sample
was able to be recovered from the 72 - 73m interval.
The results are highly encouraging as the gold and base metal
anomalism may represent a supergene enrichment of primary
mineralisation at depth, potentially around the untested EM plate
target, and the water inflows may indicate a significant geological
structure, also promising for transporting and focusing gold-copper
mineralising fluids. Completion of the diamond core tails and
testing of the EM plate is a priority for the 2023 programme.
Ground EM Surveying
Detailed 1D and 2D re-processing of high priority zones within
the aerial electromagnetic datasets was completed as part of the
2022 work programme. An additional Ground Electro-Magnetic (GEM)
survey was completed over the Pearl and A35 targets to better
define the geometry and location of the interpreted bedrock
conductors, prior to drilling. Approximately 20-line kilometres of
fixed loop GEM data were collected, over the Pearl and A35 target
areas (see Figure 1).

Soil Sampling
A total of 339 soil samples were collected over the western part
of the Scallywag licence (see Figure 3). Samples were collected
mainly 100m apart, up to 200m in places, on 300 - 800m spaced, east
south east orientated, available cleared tracks. This work was
designed to test the efficacy of the Ultra Fine Fraction analysis
method which is considered useful in areas of sandy, thicker cover.
Results were low in tenor and inconclusive given the small sample.
Further surface sampling options are being evaluated given the
relatively modest cover known in the north western part of the
tenement.
Next Steps
The 2023 exploration programme at Scallywag is designed to
complete the testing of the mineralisation at the Pearl and A35
prospects as well as the previously defined GEM conductors at the
Swan, A35 and A34 prospects with diamond core tails to the RC
pre-collars
Infill and extensional surface geochemistry in suitable areas
which follows up results from the 2022 Ultra Fine Fraction
geochemistry programme will also be completed.

About Greatland
Greatland is a mining development and exploration company
focused primarily on precious and base metals.
The Company's flagship asset is the world-class Havieron
gold-copper project in the Paterson region of Western Australia,
discovered by Greatland and presently under development in joint
venture with ASX gold major, Newcrest Mining Limited.
Havieron is located approximately 45km east of Newcrest's
existing Telfer gold mine. The box cut and decline the Havieron
orebody commenced in February 2021. Development continues to
accelerate with record advancement achieved in the December 2022
quarter. Havieron is intended to leverage the existing Telfer
infrastructure and processing plant. Access to Telfer will de-risk
the development, reduces capital expenditure and lowers the
project's carbon footprint.
Greatland has a proven track record of discovery and exploration
success and is pursuing the next generation of tier-one mineral
deposits by applying advanced exploration techniques in
under-explored regions. Greatland has a number of exploration
projects across Western Australia and in parallel to the
development of Havieron is focused on becoming a multi-commodity
miner of significant scale.

Ground EM Data Collection:
In late September through
early October 2021, Vortex
Geophysics on behalf of Greatland
Gold undertook the collection
of 4.2-line kilometres of
Fixed Loop electromagnetic
data and 17.2-line km of Moving
Loop ground electromagnetic
data. The traverses were undertaken
over five target areas identified
from the 2020 Heliborne EM
survey
The data collection traverses
were customised in orientations
such as to avoid crossing
sand dunes. Initial survey
planning was to collect the
data using an In-loop configuration,
however strong "IP" effects
recorded in the data resulted
in a change of the survey
design to Slingram. Consequently,
some In-loop traverses were
recollected using the Slingram
configuration. Additionally,
a small, Fixed Loop survey
was undertaken over anomaly

Geology
* Deposit type, geological setting and style of * Exploration is for intrusion related and orogenic,
mineralisation structurally controlled Au-Cu deposits similar to
Telfer, Havieron and Winu, all located in
Neo-Proterozoic Yeneena Group sediments of the
Paterson Province, Western Australia
------------------------------------------------------------ ------------------------------------------------------------
Drill
hole * A summary of all information material to the * Greatland drill hole collar details are listed in -
Information understanding of the exploration results including a Table 1 and anomalous results in Table 2
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
------------------------------------------------------------ ------------------------------------------------------------
Data
aggregation * In reporting Exploration Results, weighting averaging * No economically significant results have been
methods techniques, maximum and/or minimum grade truncations reported, and no data aggregation methods have been
(eg cutting of high grades) and cut-off grades are applied
usually Material and should be stated
* Where anomalous results are quoted (Table 2) the
* Where aggregate intercepts incorporate short lengths samples have been selected as follows:
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 * Au >0.1ppm; or
aggregations should be shown in detail
* Ag >2ppm; or
* The assumptions used for any reporting of metal
equivalent values should be clearly stated
* Cu >500ppm; or
* Bi >5ppm; or
* Pb >200ppm; or
* Zn >1000ppm
------------------------------------------------------------ ------------------------------------------------------------
Relationship
between * These relationships are particularly important in the * No economically significant results are reported, and
mineralis-ation reporting of Exploration Results there is no known relationship between reported
widths widths and the geometry of any mineralisation
and intercept
lengths * 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 (eg 'down hole length, true width not known')
------------------------------------------------------------ ------------------------------------------------------------
Diagrams
* Appropriate maps and sections (with scales) and * Maps and a Section are provided in Figures 1-3. No
tabulations of intercepts should be included for any significant discovery is reported
significant discovery being reported These should
include, but not be limited to a plan view of drill
hole collar locations and appropriate sectional views
------------------------------------------------------------ ------------------------------------------------------------
Balanced
reporting * Where comprehensive reporting of all Exploration * The reporting is considered balanced
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
------------------------------------------------------------ ------------------------------------------------------------
Other
substantive * Other exploration data, if meaningful and material, * No other substantive exploration data other than that
exploration should be reported including (but not limited to): provided in the figures
data 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
------------------------------------------------------------ ------------------------------------------------------------
Further
work * The nature and scale of planned further work (eg * Further drilling of the ground EM targets including
tests for lateral extensions or depth extensions or the Swan target is planned for 2022, along with soil
large-scale step-out drilling) sampling, geophysical follow up and possible ground
EM
* Diagrams clearly highlighting the areas of possible
extensions, including the main geological
interpretations and future drilling areas, provided
this information is not commercially sensitive
