TORONTO, Sept. 12, 2022 (GLOBE NEWSWIRE) -- YAMANA GOLD INC. (TSX:YRI; NYSE:AUY; LSE:AUY) ("Yamana" or the "Company") provides notice that it has completed technical reports under National Instrument 43-101 for the balance of its major mines and projects for which technical reports were not previously available. With the completion of technical reports for the Minera Florida gold mine in central Chile, the Cerro Moro gold and silver mine in Santa Cruz, Argentina, the Wasamac gold project in Quebec, Canada, and the MARA copper and gold project in Catamarca, Argentina, Yamana has now made public technical reports for all of its major mines and projects. Technical reports on the core material operations at the Canadian Malartic gold mine, the Jacobina gold mine and the El Peñón gold and silver mine were previously filed with Canadian securities regulators and remain current.

The public availability of these technical reports represents a recent policy decision of the Company to have on public file technical reports for all major mines and projects regardless of materiality.

The technical reports should be read in conjunction with the most recent updates disclosed by the Company, in particular the Yamana 1.5 Plan, which outlines in detail, including capital and operating costs, the growth prospects of the Company above and beyond the production plans set forth in the technical reports, to a production level of at least 1.5 million gold equivalent ounces, representing a minimum 50 per cent growth rate, and the ongoing exploration and optimization studies which followed publication of the Yamana 1.5 Plan. When read in their entirety, these reports, materials, presentations and documents demonstrate Yamana's true value proposition, which significantly exceeds the market value of the Company.

The details of the Yamana 1.5 Plan and discussions about long-term value creation and upside optionality across Yamana's portfolio may be found in the April 5, 2022 Investor Day presentation. An update on the results and potential of the Company's exploration program may be found in the July 27, 2022 exploration update. Both the Investor Day presentation and the exploration update can also be found on the Company's website at www.yamana.com.
