Pan American Silver Reports Mineral Reserves and Mineral Resources as at June 30, 2023

Vancouver, B.C. - August 24, 2023 - 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."

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
