Glencore to Acquire Newmont’s 18.75% Shareholding in the Mara Project

TORONTO, Sept. 23, 2022 - Today Glencore International AG ("Glencore") announced, and has made Yamana Gold Inc. (TSX:YRI; NYSE:AUY; LSE:AUY) ("Yamana" or the "Company") aware under the terms of the MARA joint venture ("MARA JV"), that it has reached an agreement (the "Agreement") to acquire Newmont Corporation's ("Newmont") 18.75% shareholding in the MARA Project ("MARA" or the "Project"). Following completion of the Agreement, Yamana remains the MARA JV operator with a 56.25% interest in MARA, with Glencore owning the remaining 43.75%. Yamana welcomes Glencore's increased stake in the Project and believes the Agreement is a positive step for MARA, as the consolidation of ownership amongst partners provides a further endorsement of the quality and strategic optionality inherent in the Project, as well as underpinning its value.

Under the terms of the Agreement, Glencore will pay Newmont $124.9 million upon closing and a $30 million deferred payment upon commercial production subject to an annual interest charge of 6%. Total deferred consideration is capped at $50 million. Based on the NPV(8%) of $1.9 billion as determined by the 2020 PFS-B results summarized below, the implied P/NAV transaction multiple is approximately 0.5x which Yamana believes is in line with comparable precedent transactions for the sale of a minority interest in projects at similar stage of development.

Glencore previously operated Minera Alumbrera, in which Yamana was a partner. Currently Minera Alumbrera is part of the MARA Project after its integration with Minera Agua Rica, which Yamana wholly owned. Glencore has worked with Yamana in the formation of the MARA JV, the integration of the processing plant, related infrastructure and other assets of Minera Alumbrera with the Agua Rica deposit, and the advancement of the Project since then.

Yamana looks forward to continuing its work with Glencore and the local stakeholders as MARA advances its permitting, engineering, social licensing and field work towards the goal of finalizing the feasibility study and the environmental and social impact assessment, which the Company expects will further increase the Project's value.

On a 100% basis, MARA has Proven and Probable Mineral Reserves of 11.8 billion pounds of copper and 7.4 million ounces of gold contained in 1.1 billion tonnes of ore⁽¹⁾. Based on the results of the PFS(B) completed in 2020, the project highlights include:

• Initial long mine life of 28 years
• Annual ore feed of 42 million tonnes per year
• Annual production for the first 10 full years of 556 million pounds of copper equivalent production⁽²⁾
• Cash costs⁽³⁾ of $1.32 per pound and AISC⁽³⁾ of $1.44 per pound for the first 10 years of production
• Initial capital of $2.78 billion
• NPV of $1.906 billion and an IRR of 21.2% assuming metal prices of $3.00 per pound of copper, $1,300 per ounce of gold price, $18.00 per ounce of silver, $11.00 per pound of molybdenum and using an 8% discount rate
• The project economics increase to an NPV of greater than $3 billion and an IRR of approximately 30% assuming $3.50 per pound of copper and $1,600 per ounce of gold

ENDNOTES

(1) Summary of MARA's attributable gold and copper Mineral Reserves. Mineral Reserves are estimated using a variable metallurgical recovery. Average metallurgical recoveries of 86% Cu, 35% Au, 43% Ag, and 44% Mo were considered. Open pit mineral reserves are reported at a variable cut-off value averaging $8.42/t, based on metal price assumptions of $3.00/lb Cu, $1,250/oz Au, $18/oz Ag, and $11/lb Mo. A LOM average open pit costs of $1.72/t moved, processing and G&A cost of $6.70/t of run of mine processed. The strip ratio of the mineral reserves is 1.7 with overall slope angles varying from 39° to 45° depending on the geotechnical sector.

(2) Copper equivalent metal includes copper with gold, molybdenum, and silver converted to copper-equivalent metal based on the following metal price assumptions: $6,614 per tonne of copper, $1,250 per ounce for gold, $24,250 per tonne for molybdenum, and $18.00 per ounce for silver.

(3) A non-GAAP financial performance measure. Please refer to section 11 of the Company's Management's Discussion and Analysis for the quarter ended June 30, 2022, dated July 28, 2022, as filed on SEDAR at www.sedar.com, EDGAR and incorporated by reference to this press release.
