Cautionary Note
 Regarding Forward-Looking Statements

CAUTIONARY NOTE REGARDING FORWARD-LOOKING STATEMENTS: This presentation 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 leverage ratios,
information with respect to the Company’s strategy, plans, guidance and production outlook, or future financial or operating performance, continued advancements at Minera Agua Rica Alumbrera (MARA),
expected production and costs, and the general economics of the MARA project, mine plan optimization, simplified permitting process as a result of relying on Alumbrera processing facilities, expected higher
throughput rates without significant capital expenditure increases, plans and objectives for future exploration, future feasibility studies and environmental impact assessment in 2022, and the potential for
future additions to mineral resources and mineral reserves and mine life extensions. 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 the impact of general domestic and foreign business, economic and
political 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, copper,
silver and zinc), currency exchange rates (such as the Brazilian real, the Chilean peso, the Argentine peso, and the Canadian dollar versus the United States dollar), interest rates, possible variations in ore
grade or recovery rates, changes in the Company’s hedging program, changes in accounting policies, changes in Mineral Reserves (as defined herein) and Mineral Resources (as defined herein), and risks related
to acquisitions and/or dispositions, changes in project parameters as plans continue to be refined, changes in project development, construction, production and commissioning time frames, risks associated
with infectious diseases, including COVID-19, nature and climatic condition risks, risks related to joint venture operations, the possibility of project cost overruns or unanticipated costs and expenses, potential
impairment charges, higher prices for fuel, steel, power, labour and other consumables contributing to higher costs and general risks of the mining industry, including but not limited to, 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, environmental and 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, 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, vulnerability of
information systems and risks related to global financial conditions, 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 expectations in connection with the upside potential of the MARA project, including production, financial and operational
performance and results at the MARA project and may not be appropriate for other purposes.

Non-GAAP Measures:
The Company has included certain non-GAAP financial measures and additional line items or subtotals, which the Company believes that together with measures determined in accordance with IFRS, provide
investors with an improved ability to evaluate the underlying performance of the Company. Non-GAAP financial measures do not have any standardized meaning prescribed under IFRS, and therefore they may
not be comparable to similar measures employed by other companies. The data is intended to provide additional information and should not be considered in isolation or as a substitute for measures of
performance prepared in accordance with IFRS. The non-GAAP financial measures included in this presentation include: Free cash flow, cash costs per copper equivalent pound, EBITDA, all-in sustaining costs
per copper equivalent pound. Please refer to section 11 of the Company’s current third quarter Management’s Discussion and Analysis, and associated press release which is filed on SEDAR and includes a
detailed discussion of the usefulness of the non-GAAP measures. The Company believes that in addition to conventional measures prepared in accordance with IFRS, the Company and certain investors and
analysts use this information to evaluate the Company’s performance. In particular, management uses these measures for internal valuation for the period and to assist with planning and forecasting of future
operations.

                                           •   Low AISC (US$1.49/lb) provides both gross margin and leverage to the copper price
   economics and ramp-                     •   Expected to commence production just as the copper supply gap is expected to materialize
   up timing                               •   Total LOM Capital of $3.9bn with initial capital of $2.8bn after reclassifying mining fleet costs from sustaining

                                           •   Conventional open-pit, truck and shovel mining operation and concentrator
                                           •   Higher certainty of capital costs due to minimum processing plant investment requirements
   De-risked profile
                                           •   Use of existing Alumbrera facilities offers a deep real life understanding of the flowsheet performance, productivities
   driven by Agua Rica -                       and cost profiles not typically available for greenfield projects and is expected to simplify the permitting process
   Alumbrera integration                   •   Historical operations at Alumbrera and local representation in Agua Rica provide intimate environmental and social

                                           •   Forecast to produce over 900ktpa of concentrate over its first 5 years; copper smelters increasingly demanding
                                               quality concentrate to blend and backfill excess supply
   Attractive copper                       •   MARA is currently forecast to produce a “custom clean”3 concentrate (LOM average arsenic level of 0.4%) during a
   concentrate                                 time when the global copper concentrate supply is expected to show an increase in arsenic content
                                           •   Low impurities beyond arsenic
                                           •   Significant by-product credits (19% of LOM revenue)

                                           •   Further Mine plan optimization ongoing; resequencing has showed and optimized grade profile and reduced re-handle
                                               costs, and further improving base LOM economics
                                           •   Softer Agua Rica ore allows for full utilization of installed capacity; recent studies show that higher throughput rates
   Potential for                               (up to 120ktpd+) could also be achievable without significant capex increases
   upside/expansion                        •   Potential resource expansions available at Agua Rica due to reclassification of inferred mineral resources within the
                                               pit shell (mine plan based only on mineral reserves) and Alumbrera open pit remaining mineral resources

   • Further mine plan optimization under review; with new
     sequencing expected to optimize production profile and
     reduce re-handle costs
   • Agua Rica mine life extension
     o Existing Inferred mineral resource within the pit and the                                      Inferred Resources with
       deposit open at depth offer significant opportunity for                                        potential to define

     o Mineral Resource below the Alumbrera open pit presents
       an alternative for operators to supplement the Agua Rica                                                Alumbrera processing facilities
       ore or start production earlier, particularly in an
       attractive copper price environment
   • Regional exploration
     o MARA is located in one of the most prolific copper
       producing regions in the world, providing substantial
       exploration upside

Integration Agreement
MARA JV formally established in 2020

• On 7 March 2019, Yamana, Glencore and Goldcorp (now Newmont) (the “Owners”), recognizing the significant
  economic benefits of using Alumbrera facilities for processing Agua Rica ore, entered into an integration agreement
  (the “Integration Agreement”)

• The purpose of the Integration Agreement was:
  o The establishment of the split of relative economic interests of the Owners in the combined integrated operation –
    which are 56.25% Yamana, 25% Glencore and 18.75% Newmont Goldcorp and the creation of a Technical Committee
    to advance the PFS and FS studies along with other project matters
  o The facilitation of the interim period following which the Owners could complete an Integration Transaction,
    entering into a joint venture agreement and associated documents which will govern future development and
    operations of the integrated project

• On December 18, 2020, the Owners announced the completion of the formal Integration thereby entering into a JV:
  o Yamana is the Manager of the JV and responsible of advancing the project to a construction decision
  o A series of committees were formed to provide guidance and oversight on the project, as well as compliance and
    HSEC matters
  o The Alumbrera cash balances of US$220 M as of December 31st, 2020 became part of the MARA project

• The project expenses are financed pro-rata to the ownership percentages

• The product is available to the Owners for purchase pro-rata to their ownership percentages
