YAMANA GOLD INC. (TSX:YRI; NYSE:AUY; LSE:AUY) (“Yamana” or “the
Company”) today reported significant progress on the Phase 2
expansion of the Jacobina mine to increase throughput to 8,500
tonnes per day and raise production to 230,000 ounces per year. The
Company also announced strong exploration results at Jacobina that
expand the operation’s mineral resource and support the phased
expansion, underscoring Jacobina’s exceptional long-term growth
potential and ability to further extend strategic mine life.
Phase 2 Expansion
Highlights
- Successful trials conducted at
Jacobina during the second quarter demonstrate that the processing
plant can consistently and reliably achieve a daily operating
throughput above 8,000 tonnes per day (tpd), significantly higher
than nameplate capacity, and a monthly average of at least 7,500
tpd, as was achieved in May of this year.
- The Company will achieve the Phase
2 rate of 8,500 tpd by implementing a simplified approach of
debottlenecking and incremental operational improvements, without
requiring the installation of an additional ball mill. This
approach is expected to significantly reduce capital expenditure,
increase energy efficiency, and de-risk the project.
- Capital costs are expected to be
significantly lower than the original planned capital estimated in
the Phase 2 pre-feasibility study, an amount not exceeding $15
million to $20 million.
- Subject to successful completion of
required permit modifications, Jacobina expects to begin processing
at 8,500 tpd by the second half of 2023.
- Engineering for the Phase 3
expansion to 10,000 tpd will advance in parallel with the Phase 2
expansion, with the plant modification originally planned for Phase
2 now considered adequate for Phase 3. A feasibility study for
Phase 3 is scheduled for completion in 2023 and project
commissioning is still on track for 2027.
Exploration Highlights
- At Canavieiras Central, exploration
drilling has confirmed and expanded all of the mineralized reefs
with solid grades and widths along 500 metres of new strike length,
defining a continuous mineralized zone extending south from
Canavieiras Central to Canavieiras Sul, expected to generate new
indicated mineral resources by year end.
- Infill and exploration drilling at
the north end of the Morro do Vento sector confirms good grades and
widths for conversion to indicated mineral resources, while
aggressive exploration step-outs down dip on the Main reef zone
have provided strong results, demonstrating down dip continuity. An
aggressive drilling program is underway to test the down dip target
at Morro do Vento over a strike length of more than two
kilometres.
- At João Belo, exploration drilling
has demonstrated excellent potential south of the João Belo mineral
resource area, with positive results along a 3.7 kilometre-long
corridor. Drilling in 2019-2020 has defined an entirely new mineral
resource area at João Belo Sul with 536,000 ounces of gold (8.7
million tonnes grading 1.91 grams per tonne (“g/t”) of gold) of
inferred mineral resources. Drilling is ongoing at this newly
discovered zone and to the immediate south of João Belo at the João
Belo South Extension, where a number of positive drill holes have
defined a significant mineralized zone adjacent to mine
infrastructure that will be modelled for further mineral resource
by year end.
PHASE 2 UPDATE
Incremental Improvements to Increase
Processing Capacity to 8,500 TPD
The Jacobina processing plant continues to
exceed expectations, averaging 7,500 tpd in May and approximately
7,200 tpd over the full second quarter, a 5% increase compared to
the previous quarter. Throughput for the balance of the year is
expected to increase to rates above those experienced in the second
quarter to approximately 7,500 tpd which represents the permitted
operational point. The success reflects a simplified approach to
complete the Phase 2 expansion, which will be achieved through
incremental debottlenecking of the processing plant and tailings
system combined with operational improvements, without requiring
the installation of an additional ball mill. This approach is
expected to significantly reduce capital expenditures, improve
energy efficiency, and de-risk the project .
During the first quarter, a new Falcon
concentrator and cyclone bank were installed, while an additional
Knelson concentrator was installed in the second quarter. Other
initiatives include an increase in the diameter of the pipeline
feeding the tailings storage facility from 10 to 16 inches to
relieve pipe pressures thereby increasing design limits.
Additionally, the Jacobina processing team
continued to fine-tune the operation of the plant, optimizing the
aperture of the crushers and sizing of the screens to reduce the
feed size of material entering the ball mills, thereby improving
milling performance. Furthermore, a new combination of mill liners
and grinding balls allowed an increase in throughput while
maintaining grinding size.
In May and June, Jacobina conducted trials to
test the existing capacity of the processing plant and evaluate the
optimal processing rate, and identify bottlenecks for future
throughput increases. The May trial was conducted over six
consecutive days, during which the processing plant exceeded 8,000
tpd, which is significantly above nameplate capacity, while
maintaining a gold recovery of more than 96% and achieving a
maximum daily throughput of 8,176 tonnes. A follow-up trial was
conducted over a two-week period in June in which the processing
plant exceeded 8,000 tpd for 10 days, averaging 8,179 tpd, and
achieving a maximum daily throughput of 8,609 tpd. All told,
throughput at Jacobina exceeded 8,000 tpd for 21 days during the
second quarter. Following completion of the trials, operation of
the plant is currently limited to a maximum monthly average
processing rate of 7,500 tpd such as defined by the Company’s
operating permit pending changes to permitting, which are in
progress.
Gold production was higher than budget in the
second quarter as a result of higher-than-planned throughput. The
supplementary mill feed in the second quarter came from ore in
stockpiles, which had been created over several quarters for the
purpose of providing mill feed to evaluate realizable throughput
above the nameplate level for the plant. While this had a modest
impact on unit costs per ounce, it ensures that the current plant’s
optimized throughput is sustainable. With a better understanding of
the sustainable throughput of the plant, the Company is now
increasing mine rates to bring those in line with the higher
processing rate. This is expected to be achieved by the end of 2021
at which time the Company will no longer rely on stockpiled ore.
Although mining grade is expected to be in line or better than plan
for the second half of the year, the stockpile reclaiming strategy
will continue for the remainder of the year. Consequently, the
Company anticipates continued higher throughput and increased
number of ounces of production as compared to plan, although at
slightly higher costs than plan, as mining rates increase. This
trade off of temporarily relying on much lower grade stockpile ore
in favour of throughput is a necessary part of the Phase 1
optimization and has provided operational support for the
simplified Phase 2 expansion. By end of year, and in the years to
follow, as mining rates match throughput, feed grade is expected to
normalize without reliance on stockpiles thereby resulting in
sustainable, higher production at lower unit costs.
Following the better-than-expected processing
performance in the first half of 2021, operational data from the
aforementioned trials was used to calibrate the processing model
and set the baseline for future expansions. These results confirm
that the Jacobina processing plant has opportunities for further
incremental capacity increases while maintaining high recoveries.
The objective of the Phase 2 expansion remains unchanged: to
achieve sustainable throughput of 8,500 tpd while maintaining gold
recovery of 96% to 97%, increasing gold production to approximately
230,000 ounces per year based on recent plant performance and
studies. Yamana is confident that this objective can be achieved
with its simplified approach to continue incremental
debottlenecking and operational improvements without requiring an
expansion of the grinding circuit as originally contemplated.
Opportunities under evaluation include
post-commissioning operational adjustments to the new Knelson and
Falcon concentrators and further optimization of the crushing
circuit. Additionally, installation of fine screens has the
potential to improve classification efficiency compared to the
existing cyclones, preventing particles finer than target grind
size from reporting back to the ball mills, allowing mill capacity
to be spent more efficiently on only particles requiring size
reduction. Test work is planned for the third quarter to further
evaluate this opportunity. Minor upgrades to the back end of the
processing plant and tailings pumping system are required to
sustain the higher throughput rates.
To support the higher processing rate,
production from the underground mine continues to ramp up as a
result of improvements to the ventilation circuits, addition of
loading and hauling equipment to the mine fleet, and optimization
of the shotcreting work groups, which has reduced development cycle
times and provided access to additional production zones.
Simplified Approach to Require a
Fraction of the Original Planned Capital
The simplified expansion approach is a
continuation of the strategy that has been the basis for the
quarter-over-quarter success of Jacobina over the past several
years, and is expected to require significantly lower capital than
originally planned in the Phase 2 pre-feasibility study, an amount
not expected to exceed $15 million to $20 million.
Jacobina continues to work closely with
regulatory authorities to increase the permitted throughput to
8,500 tpd and has the potential to achieve the Phase 2 objectives
earlier than planned. Subject to successful completion of required
permit modifications, Jacobina would begin processing at the new
Phase 2 rate by the second half of 2023.
As the Company’s expansion strategy is well
advanced, Jacobina is now seen as a multi-decade, low cost
operation with a planned production level of at least 230,000
ounces per year, with annualized production expected to achieve
this level by the second half of 2023.
Evaluation of Phase 3 Expansion to
10,000 TPD Advancing; Plant Modifications Originally Planned for
Phase 2 Now Considered Adequate for Phase 3
As previously presented in the Company’s 10-year
production outlook, Yamana is evaluating a
further expansion at Jacobina to increase throughput to
10,000 tpd, referred to as Phase 3. With the Phase
2 expansion now underway with a simpler process at reduced
capital costs, the Company will now pursue the Phase 3 expansion as
part of a comprehensive plan which aligns the processing plant,
underground mine, tailings strategy, and permitting, while managing
capital expenditure and cash flow.
During the second quarter, the Company
discontinued basic engineering and development of a detailed
project execution plan for the installation of a third grinding
line, which was originally intended as part of the Phase 2
expansion to 8,500 tpd as a result of the optimizations referred to
above. With an improved Phase 2 plan which no longer requires a
third grinding line, the Company is now evaluating the installation
of a third grinding line not to achieve the planned 8,500 tpd
contemplated for the Phase 2 expansion, but for the Phase 3 plant
expansion to 10,000 tpd.
Updated modelling indicates that the 10,000 tpd
target throughput could be achieved with only two ball mills in
operation, allowing for grinding line two to be suspended. Compared
to the pre-feasibility study completed in 2020, the detailed design
incorporates additional test work and geotechnical analysis
together with several improvements to the plant design for line
three including an optimized design of the additional crushed ore
silo and associated conveyors and increased recovery from gravity
concentration using the same gravity circuit that is now installed
on line two. Further improvements will continue to be
evaluated.
With the processing plant expansion plan well
understood, the Jacobina team is now focusing on the mine plan and
infrastructure required to support the higher throughput rate
including a haulage optimization study to evaluate alternative
solutions for transporting ore from the underground mines to the
processing plant.
One promising ore haulage solution is the use of
Rail-Veyor technology, for which engineering was completed in the
first quarter of 2021. The installation of the Rail-Veyor system as
the primary method of ore haulage from the Canavieiras mines to the
processing plant stockpiles would provide a robust and low-cost
method of haulage. Evaluation of the Rail-Veyor concept is
continuing as part of the overall haulage optimization study.
Engineering for the Phase 3 expansion to 10,000
tpd will advance in parallel with the Phase 2 expansion, and the
processing model will continue to be updated to integrate
operational data from Phase 2, with a feasibility study for Phase 3
scheduled for completion in 2023.
Comprehensive Tailings Management
Strategy for Long-Term Sustainability
To complement the Jacobina phased expansion,
Yamana has adopted a comprehensive Jacobina life-of-mine tailings
management strategy, that substitutes surface deposition of
tailings, with underground tailings disposal as backfill. The
Company has initiated several studies to ensure long-term
sustainability and to reduce the environmental footprint of the
operation. Test work conducted in 2020 confirmed that both paste
backfill and hydraulic backfill are technically feasible options
for disposal of tailings into underground voids, thereby minimizing
the quantity of tailings stored on surface. Additionally, use of
backfill is expected to improve underground stope stability and
minimize the requirements to leave behind pillars in ore, resulting
in increased mining recovery and reduced dilution.
As a first step, a hydraulic backfill plant
provides a relatively simple and low capital cost solution for
underground deposition of 2,000 tonnes of dry tailings per day,
with the extra advantage that hydraulic backfill can be placed into
historic voids with minimal cement content, significantly reducing
the operating cost. Utilization of historic voids for backfilling
will also allow Jacobina to gradually introduce backfill into the
mining sequence without impacting the production rate of the mine.
In March 2021, Jacobina completed a feasibility study for the
installation of a hydraulic backfill plant. The initial capital
cost for the backfill system is estimated at $8.0 million. The
Company has decided to move forward with the hydraulic backfill
plant project and is in the permitting phase. The permit required
for the backfill project is separate from the one required for the
Phase 2 expansion, although both are being pursued simultaneously.
Additionally, a conceptual study is underway to evaluate further
opportunities for a dry stack tailings facility and/or a paste
backfill plant in parallel to the hydraulic backfill plant, which
could provide opportunities in the future for additional storage of
tailings to support future mineral reserve development.
Existing surface tailings capacity, combined
with tailings storage underground as backfill will be sufficient
for life of mine production at Jacobina at the planned increased
processing rates.
EXPLORATION UPDATE
The Jacobina mine continues to outperform,
consistently exceeding production and exploration expectations.
Exploration has ramped up in support of the phased expansion plan
with results continuing to expand mineral inventory in João Belo,
Canavieiras and Morro do Vento, adding high-quality mineral
resources and mineral reserves close to mine infrastructure.
Results also demonstrate the mine’s ability to continue to
significantly grow mineral reserves and mineral resources beyond
depletion, notwithstanding increasing production, underscoring
Jacobina’s exceptional long-term growth potential and ability to
further extend strategic mine life.

Mineral Envelope Expanded at Canavieiras
Central
At Canavieiras, exploratory and conversion
drilling programs have confirmed the presence of all mineralized
reefs south of Canavieiras Central, expanding the mineral envelope
continuously more than 500 metres southward to the northern limit
of Canavieiras Sul. Drilling results from this sector have been
impressive, with both the LU and MU reefs generating higher grade
intercepts over wide intervals and defining high-quality
mineralization close to the current mine infrastructure. Notable
results include the following estimated true width intervals: 3.55
g/t of gold over 3.64 metres and 4.29 g/t of gold over 6.16 metres
at MU reef; 6.71 g/t of gold over 4.71 metres and 5.84 g/t of gold
over 2.15 metres at LU reef (CANEX00108); 4.01 g/t of gold over
18.50 metres at MU reef and 11.47 g/t of gold over 6.39 metres,
including 20.50 g/t of gold over 2.35 metres at LU reef
(CANEX00113); 5.90 g/t of gold over 6.93 metres at MU reef and 4.06
g/t of gold over 4.54 metres at LU reef (CANEX00107); 5.95 g/t of
gold over 6.01 metres and 6.29 g/t of gold over 5.08 metres at MU
reef and 7.13 g/t of gold over 5.86 metres at LU reef
(CANEX00094).
Moreover, the drilling program has also
delineated the Maneira reef, providing wide, higher grade
intercepts in this zone, which remains open for expansion to the
south. Highlights include the following estimated true width
intervals: 5.38 g/t of gold over 3.87 metres (CANEX00119); 5.79 g/t
of gold over 4.67 metres (CANEX00120); and 14.11 g/t of gold over
3.36 metres (CANEX00093). See Figure 2 and Table 2 for further
details and additional results.
Exceptional Results at Morro do
Vento
The Main reef zone at Morro do Vento has
demonstrated continuity of mineralization over a large area with
2.5 kilometers of strike length and positive drilling intercepts up
to 1,100 metres down dip of mine infrastructure, representing one
of the most important mineralized zones of the Jacobina district.
In the northern portion of Morro do Vento, the delineation drilling
program has provided strong results at Main reef, indicating
high-grade mineralization continues down dip and remains open for
growth. Notable results include the following estimated true width
intervals: 9.31 g/t of gold over 3.09 metres and 8.39 g/t of gold
over 3.63 metres (MVTEX00056); 5.24 g/t of gold over 2.55 metres
and 4.09 g/t of gold over 3.19 metres (MVTEX00057); 11.14 g/t of
gold over 2.15 metres (MVTEX00060); 4.86 g/t of gold over 4.57
metres and 5.31 g/t of gold over 2.46 metres (MVTEX00063); and 5.21
g/t of gold over 1.72 metres and 4.29 g/t of gold over 7.17 metres
(MVTEX00065).
An exploratory drill program has been initiated
to expand and define the potential of the Main reef zone down dip
and along a 2.5-kilometre corridor targeting the continuation at
depth of areas highlighted by existing positive estimated true
width drilling intercepts, including: 7.15 g/t of gold over 4.89
metres and 9.43 g/t of gold over 4.26 metres (MVTEX00048); 4.93 g/t
of gold over 3.27 metres (MVTEX43); 6.36 g/t of gold over 2.36
metres (MVTEX30) (to view these results; please see Yamana press
releases dated May 19, 2020, and September 8, 2020, available on
the Company’s website at www.yamana.com). The first deep drill hole
has been initiated, with results expected by year end. See Figures
3 and 4 and Table 2 for these and additional results.
Newly Defined Mineral Resource at João
Belo Sul
Over the last two years, the Company has
dedicated significant effort to exploration of the southern portion
of the Jacobina district, the delineation of the recently
discovered João Belo Sul sector, and to exploring extensions of
João Belo, historically the most productive mine in the complex
with more than one million ounces of past production. At João Belo
Sul, located two kilometres south of the João Belo mineral resource
area, drilling has generated significant results and defined a
continuous mineral envelope in the LMPC reef over a 900-meter
north-south strike length and 600 metres down dip. Significant
results include the following estimated true width intervals: 3.85
g/t of gold over 4.86 metres (JBEX00033); 3.04 g/t of gold over
5.83 metres, including 12.43 g/t of gold over 0.97 metres
(JBEX00029); 3.40 g/t of gold over 4.19 metres (JBEX00030); and
5.83 g/t of gold over 4.00 metres, including 8.10 g/t of gold over
2.40 metres (JBEX00031).
An initial mineral resource estimate based on
surface drilling only has been defined at João Belo Sul. The
underground inferred mineral resources include 536,000 ounces of
gold within 8,738,000 tonnes at an average grade of 1.91 g/t of
gold. See Table 1.

- The Qualified Persons for the
mineral resource estimates are Dr. Jean-Francois Ravenelle, P.Geo.
and Dominic Chartier, P.Geo., both full time employees of Yamana
Gold Inc. The mineral resource estimate follows 2019 CIM
definitions and guidelines for mineral resources.
- The effective date for the mineral
resource estimate is June 30, 2021.
- Mineral resources were evaluated
using the ordinary kriging weighting algorithm informed by capped
composites and constrained by three-dimensional mineralization
wireframes.
- A bulk density varying from 2.63 to
2.64 g/cm3 was used to convert volume to tonnage.
- Mineral resources are constrained
by potentially mineable shapes based on a minimum mining width of
1.5 m and considering internal waste and dilution. Underground
cut-off grade of 1.00 g/t gold, which corresponds to 75% of the
cut-off used to estimate the mineral reserves at the Jacobina Mine
that considers a gold price of $1,250/oz and a metallurgical
recovery of 96.5%.
- Mineral resources are not mineral reserves and do not have
demonstrated economic viability.
- All figures are rounded to reflect
the relative accuracy of the estimate. Numbers may not add up due
to rounding.
Mineralization remains open for expansion along
strike and to depth, and an updated mineral resource is expected
for year end. The potential of this 3.7 kilometer-long district is
further demonstrated by drilling at the João Belo South Extension,
immediately south of the João Belo mineral resource area, where
exploratory drilling has intercepted the same LMPC reef. Notable
results in this sector include the following estimated true width
interval 6.21 g/t of gold over 3.10 metres (JBEX021). Existing
positive estimated true width drill results from this area (see
press release dated May 19, 2020, available on the Company’s
website www.yamana.com) include: 4.13 g/t of gold over 2.04 metres
(JBEX014); 4.11 g/t of gold over 3.38 metres (JBEX012); and 3.17
g/t of gold over 4.83 metres (JBEX009).
These results reveal the presence of a
continuous sequence of mineralized reefs along more than 3.7
kilometers of strike length, extending from João Belo to João Belo
Sul. See Figure 5 and Table 2 for these and other results.
Overall, exploration continues to successfully
identify and define new extensions of current producing sectors of
the Jacobina mine, with exceptional results replacing depletion
with high-quality mineral reserves and mineral resources close to
current mine infrastructure. Furthermore, aggressive step out
exploration drilling is opening up new, extensive frontier areas
available for mineral resource growth in new sectors of the
property, as exemplified by recent successes at João Belo Sul and
Morro do Vento Main reef. These discoveries support a strategic
mine life of several decades at a production level well above the
planned Phase 2 expansion annual production level of 230,000
ounces, and likely 270,000 ounces, which is the planned annual
production level for the Phase 3 expansion as elaborated
herein.

Qualified Persons
Scientific and technical information contained
in this press release has been reviewed and approved by Henry
Marsden (P. Geo. and Senior Vice President, Exploration). Mr.
Marsden is an employee of Yamana Gold Inc. and a “Qualified Person”
as defined by Canadian Securities Administrators' National
Instrument 43-101 - Standards of Disclosure for Mineral
Projects.
The mineral resource estimate reported for João
Belo Sul has been reviewed by Dr. Jean-François Ravenelle (P.Geo.
and Director, Geology) and Dominic Chartier (P.Geo. and Senior
Manager, Geology). Both employees of Yamana Gold Inc. and
“Qualified Persons” as defined by Canadian Securities
Administrators' National Instrument 43-101 - Standards of
Disclosure for Mineral Projects.
Quality Assurance and Quality
Control
Yamana incorporates a Quality Assurance and
Quality Control (“QA/QC”) program for all of its mines and
exploration projects which conforms to industry best practices.
Samples are transported in security sealed bags
for preparation at ALS and SGS analytical laboratories,
both ISO 9001:2008 and 17025 certified laboratories. At Jacobina
sample preparation is completed on site. Gold is analyzed by gold
fire assay with 30 grams or 50 grams aliquot and AAS finish.
Samples over 5 g/t are re-analyzed by gravimetric finish methods.
Silver is determined using a four acid digestion and AAS finish
(ore level) and samples over 30g/t are re-analyzed by gravimetric
finish methods. Five percent of all pulps are further checked by
secondary certified laboratories (ALS, SGS, Bureau Veritas) using
the same analytical methods.
All exploration diamond drill cores are split in
half by mechanical spitting or core sawing and sampled at
appropriate intervals for assay, except for small diameter drilling
(BQ) from underground setups at Jacobina where core is logged,
photographed and whole core submitted for assay. The remaining
core, coarse reject and pulps are stored on-site in a secure
location.
Quality assurance standards, duplicates, sterile
and blanks are routinely inserted into the sample stream as a
control for assay accuracy, bias, precision and contamination. The
results of these checks are tracked and failures are re-analyzed.
This information also includes pulp checks carried out in the
secondary lab.
About Yamana

CAUTIONARY NOTE REGARDING FORWARD-LOOKING
STATEMENTS: This news release contains or incorporates by reference
“forward-looking statements” and “forward-looking information”
under applicable Canadian securities legislation and within the
meaning of the United States Private Securities Litigation Reform
Act of 1995. Forward-looking information includes, but is not
limited to, information with respect to the Company’s progress on
the Phase 2 expansion and a proposed Phase 3 expansion of the
Jacobina mine to increase throughput and raise annual production,
and the Company’s exploration results at Jacobina and areas
surrounding the mine aimed at expanding the operation’s mineral
resource inventory and supporting the phased expansion,
underscoring Jacobina’s long-term growth potential and further
extending strategic mine life, including the Company’s expectation
that it will achieve the Phase 2 rate at Jacobina by implementing a
revised strategy of debottlenecking and making incremental
operational improvements that will significantly reduce capital
expenditures and risk associated with installing an additional ball
mill; that capital costs are expected to be significantly reduced
from the original planned capital; that the project will consume
significantly less power to achieve 8,500 tpd than previously
estimated in the Phase 2 pre-feasibility study for Jacobina; that,
subject to successful completion of required permit modifications,
the Company expects Jacobina to begin processing at 8,500 tpd by
the second half of 2023; that the Company will continue to evaluate
a Phase 3 expansion to increase throughput to 10,000 tpd by 2027;
that, based on the updated modelling, the target throughput rate
could be achieved with only two ball mills in operation, allowing
for grinding line #1 to be suspended; that the exploration drilling
and confirmation’s to-date at Canavieiras Central, defining a
continuous mineralized zone extending from Canavieiras Central to
Canavieiras Sul, will provide new indicated mineral resources by
year end; that infill and exploration drilling at the end of the
Morro do Vento sector and step outs down dip on the Main reef zone
will result in expected down dip continuity and that the current
drilling program underway to test the down dip target at Morro do
Vento over a strike length of more than two kilometres will prove
successful; that the potential discovered to the south of the Joao
Belo mineral resource area through exploration drilling at João
Belo will be proven, and that ongoing drilling in the newly
discovered mineral resource area at João Belo Sul, and to the
immediate south of João Belo at the João Belo South Extension,
adjacent to mine infrastructure will be successfully modelled for
further resource by year end; and that a planned production level
of at least 230,000 ounces per year at Jacobina, with annualized
production at this level, will be achieved by the second half of
2023.
Forward-looking statements are characterized by
words such as “plan", “expect”, “budget”, “target”, “project”,
“intend”, “believe”, “anticipate”, “estimate” and other similar
words, or statements that certain events or conditions “may” or
“will” occur. Forward-looking statements are based on the opinions,
assumptions and estimates of management considered reasonable at
the date the statements are made, and are inherently subject to a
variety of risks and uncertainties and other known and unknown
factors that could cause actual events or results to differ
materially from those projected in the forward-looking statements.
These factors include that incremental improvements to increase
processing capacity under the Phase 2 expansion do not prove
successful; the revised strategy to significantly reduce capital
expenditures compared to the original planned capital does not
prove successful; evaluation of a Phase 3 expansion to 10,000 tpd
and proposed plant modifications originally planned for Phase 2
expansion does not prove to be adequate for Phase 3 expansion; the
Company’s proposed comprehensive tailings management strategy for
long-term sustainability does not prove successful; ongoing
exploration results at João Belo, Canavieiras and Morro do Vento do
not ultimately result in significant growth in mineral reserves and
mineral resources in order to support Jacobina’s long-term growth
potential or the Company’s ability to further extend strategic mine
life at Jacobina; an initial inferred mineral resource for Joao
Belo Sul is not confirmed by year end 2021; unforeseen impacts on
cash flow, unforeseen impacts of COVID-19, the outcome of planned
expansion and optimization projects, production, exploration and
development, changes in national and local government legislation,
taxation, controls or regulations and/or change in the
administration of laws, policies and practices; changes in
permitting requirements; the impact of general business and
economic conditions, global liquidity and credit availability on
the timing of cash flows and the values of assets and liabilities
based on projected future conditions, fluctuating metal prices
(such as gold, silver and zinc), currency exchange rates (such as
the Brazilian Real, the Chilean Peso and the Argentine Peso versus
the United States Dollar), the impact of inflation, possible
variations in ore grade or recovery rates, changes in accounting
policies, changes in mineral resources and mineral reserves, risks
related to asset dispositions, risks related to metal purchase
agreements, risks related to acquisitions, changes in project
parameters as plans continue to be refined, changes in project
development, unanticipated costs and expenses, higher prices for
fuel, steel, power, labour and other consumables contributing to
higher costs and general risks of the mining industry, failure of
plant, equipment or processes to operate as anticipated, unexpected
changes in mine life, final pricing for concentrate sales,
unanticipated results of future studies, seasonality and
unanticipated weather changes, costs and timing of the development
of new deposits, success of exploration activities, permitting
timelines, government regulation and the risk of government
expropriation or nationalization of mining operations, risks
related to relying on local advisors and consultants in foreign
jurisdictions, environmental risks, unanticipated reclamation
expenses, risks relating to joint venture or jointly owned
operations, title disputes or claims, limitations on insurance
coverage, timing and possible outcome of pending and outstanding
litigation and labour disputes, risks related to enforcing legal
rights in foreign jurisdictions, as well as those risk factors
discussed or referred to herein and in the Company's Annual
Information Form filed with the securities regulatory authorities
in all provinces of Canada and available at www.sedar.com, and the
Company’s Annual Report on Form 40-F filed with the United
States Securities and Exchange Commission.
Although the Company has attempted to identify
important factors that could cause actual actions, events or
results to differ materially from those described in
forward-looking statements, there may be other factors that cause
actions, events or results not to be anticipated, estimated or
intended. There can be no assurance that forward-looking
statements will prove to be accurate, as actual results and future
events could differ materially from those anticipated in such
statements. The Company undertakes no obligation to update
forward-looking statements if circumstances or management’s
estimates, assumptions or opinions should change, except as
required by applicable law. The reader is cautioned not to place
undue reliance on forward-looking statements. The forward-looking
information contained herein is presented for the purpose of
assisting investors in understanding the Company’s plans,
objectives and expectations in connection with its expansion and
optimization plans, as well as exploration plans for Jacobina and
areas surrounding the mine, and may not be appropriate for other
purposes.
