VANCOUVER, British Columbia–(BUSINESS WIRE)– Pan American Silver Corp. (NYSE: PAAS) (TSX: PAAS) (“Pan American” or the “Company”) reports its estimated mineral reserves and mineral resources as at June 30, 2023, inclusive of the assets acquired through the Yamana Gold Inc. (“Yamana”) transaction. Please see the Company’s news release dated March 31, 2023, announcing the completion of the Yamana transaction for further information. Proven and probable mineral reserves are estimated to contain approximately 576.6 million ounces of silver and 12.9 million ounces of gold. Measured and indicated (“M&I”) mineral resources (excluding proven and probable reserves) are estimated to total approximately 959.1 million ounces of silver and 17.5 million ounces of gold. Inferred mineral resources total 479.4 million ounces of silver and 9.2 million ounces of gold.

“The addition of the assets from the Yamana transaction has resulted in a significant increase in Pan American’s reserve and resource base,” said Christopher Emerson, Pan American’s Vice President of Exploration and Geology. “Our exploration and geology teams are currently designing the drill programs across the combined portfolio with an emphasis on near site exploration and further resource conversion. Pan American plans to complete over 480,000 metres of drilling in 2023.”

Mineral resource estimate for the La Colorada Skarn, as at September 13, 2022, and previously reported:

(1) See table below entitled “Metal price assumptions used to estimate mineral reserves and mineral resources as at June 30, 2023”.
(2) See news release dated September 14, 2022 for further information.

Pan American plans to provide an update for the La Colorada Skarn mineral resource estimate and a Preliminary Economic Assessment of the Skarn project, as part of an updated Technical Report for the La Colorada Property to be released late 2023.

Consolidated reserve and resource highlights for the 12 months ended June 30, 2023:

• Silver mineral reserves increased from 515 million ounces to 577 million ounces, net of mining depletion. Gold mineral reserves increased from 3.6 million ounces to 12.9 million ounces.
• M&I mineral resources exclusive of proven and probable mineral reserves increased from 839 million ounces to 959 million ounces for silver and from 8.1 million ounces to 17.5 million ounces for gold.
• The marked increase in year-over-year mineral reserves and M&I mineral resources reflects the inclusion of the mineral resource and mineral reserves for the assets acquired through the Yamana transaction.
• Inferred silver mineral resource decreased from 508 million ounces to 479 million ounces, which reflects the removal of the inferred mineral resource for the Shahuindo sulphides following metallurgical test work that indicated that the resource would not have a reasonable prospect for eventual economic extraction, as described in the technical report for Shahuindo dated November 30, 2022.
• Inferred gold mineral resource increased from 5.7 million ounces to 9.2 million ounces, largely through the inclusion of the inferred mineral resources of the assets acquired through the Yamana transaction.

A detailed summary of the silver and gold mineral reserves and mineral resources as at June 30, 2023 is provided in the following tables.

Cautionary Note to US Investors Regarding References to Mineral Reserves and Mineral Resources

Unless otherwise indicated, all reserve and resource estimates included in this news release have been prepared in accordance with Canadian NI 43-101 and the Canadian Institute of Mining, Metallurgy and Petroleum (the “CIM”) — CIM Definition Standards on Mineral Resources and Mineral Reserves, adopted by the CIM Council, as amended (the “CIM Standards”). NI 43-101 is a rule developed by the Canadian Securities Administrators that establishes standards for all public disclosure an issuer makes of scientific and technical information concerning mineral projects. Canadian standards, including NI 43-101, differ significantly from the requirements of the SEC, and reserve and resource information included herein may not be comparable to similar information disclosed by U.S. companies. In particular, and without limiting the generality of the foregoing, this news release uses the terms “measured resources,” “indicated resources” and “inferred resources” as defined in accordance with NI 43-101 and the CIM Standards.

Further to recent amendments, mineral property disclosure requirements in the United States (the “U.S. Rules”) are governed by subpart 1300 of Regulation S-K of the U.S. Securities Act of 1933, as amended (the “U.S. Securities Act”) which differ from the CIM Standards. As a foreign private issuer that is eligible to file reports with the SEC pursuant to the multi-jurisdictional disclosure system (the “MJDS”), Pan American is not required to provide disclosure on its mineral properties under the U.S. Rules and will continue to provide disclosure under NI 43-101 and the CIM Standards. If Pan American ceases to be a foreign private issuer or loses its eligibility to file its annual report on Form 40-F pursuant to the MJDS, then Pan American will be subject to the U.S. Rules, which differ from the requirements of NI 43-101 and the CIM Standards.

Pursuant to the new U.S. Rules, the SEC recognizes estimates of “measured mineral resources”, “indicated mineral resources” and “inferred mineral resources.” In addition, the definitions of “proven mineral reserves” and “probable mineral reserves” under the U.S. Rules are now “substantially similar” to the corresponding standards under NI 43-101. Mineralization described using these terms has a greater amount of uncertainty as to its existence and feasibility than mineralization that has been characterized as reserves. Accordingly, U.S. investors are cautioned not to assume that any measured mineral resources, indicated mineral resources, or inferred mineral resources that Pan American reports are or will be economically or legally mineable. Further, “inferred mineral resources” have a greater amount of uncertainty as to their existence and as to whether they can be mined legally or economically. Under Canadian securities laws, estimates of “inferred mineral resources” may not form the basis of feasibility or pre-feasibility studies, except in rare cases. While the above terms under the U.S. Rules are “substantially similar” to the standards under NI 43-101 and CIM Standards, there are differences in the definitions under the U.S. Rules and CIM Standards. Accordingly, there is no assurance any mineral reserves or mineral resources that Pan American may report as “proven mineral reserves”, “probable mineral reserves”, “measured mineral resources”, “indicated mineral resources” and “inferred mineral resources” under NI 43-101 would be the same had Pan American prepared the reserve or resource estimates under the standards adopted under the U.S. Rules.
