Pan American Silver Provides 2025 Year End Exploration Update

Vancouver, B.C. – December 1, 2025 - Pan American Silver Corp. (NYSE: PAAS) (TSX: PAAS) ("Pan American" or the

"Company") released new drill results for its Jacobina, El Peñon, La Colorada, Huaron, Timmins, Minera Florida and

Cerro Moro mines.

“In 2025, we continued to advance our long-term exploration strategy aimed at replacing and growing our mineral

resources, with strong results across several key operations,” said Christopher Emerson, SVP Exploration and

Geology. “At Jacobina, drilling to the north of the Maricota deposit is confirming the potential to expand the

resource beyond currently defined limits. At El Peñon, drilling is identifying new mineralized structures both within

the main mine area and at nearby targets, including Fortuna and the newly discovered Dominadora vein. At La

Colorada, recent drilling in the eastern and deeper parts of the mine continues to return compelling grades and

widths, and we are also advancing a highly prospective replacement-style target along the contact between

limestone and volcanic rocks.”

Pan American's exploration program focuses on near-mine exploration and resource conversion throughout its

portfolio of operating mines. This release provides an exploration update on the 333,830 metres that have been

drilled at the mines referenced in this news release, which represents 70% of the total metres drilled for the

period November 1, 2024 to October 30, 2025. The Company plans to drill a total of approximately 540,000 metres

in 2025.

Cerro Moro, Argentina

Cerro Moro is an underground and open pit epithermal gold-silver mine located in the Patagonia region of

southern Argentina.

• For the period November 2024 to October 2025, exploration drilling totaled 34,764 metres, including

28,871 metres of infill drilling targeting conversion of inferred mineral resource, 4,544 metres of

exploration drilling to delineate new inferred mineral resources, and 1,349 metres of exploratory drilling

to identify new mineralization. Efforts focused primarily on defining and expanding the new Naty Condor

discovery (approximately 11 kilometres south of the operation.). Additionally, drilling was carried out

along the 3.5 kilometre-long Nini core mine structure, and on the newly defined Vein 4 structure at the

Naty open pit, approximately 23 kilometres south-southwest of the operation.

• Naty Condor, discovered in late 2023 with initial drilling in mid-2024, features mineralization along an

approximately 700 metre long northwest-trending corridor, delineated to depths of 50 to 90 metres below

surface within multiple coalescing structures that form wide, often high-grade zones. Mineralization is

hosted by and proximal with the contact between bedded sedimentary strata and felsic volcaniclastic

rocks. Mineralization remains partially open to depth and along strike to the northwest and southeast.

Notable intercepts include: 17.95m @ 13.51 g/t Au, 228 g/t Ag, incl. 2.94m @ 55.14 g/t Au, 956 g/t Ag
