Pan American Silver Discovers New High-grade Veins at the La Colorada Mine (Form 6-K)

Pan American Silver Discovers New High-grade Veins at the La Colorada Mine

Vancouver, B.C. - March 5, 2026 - Pan American Silver Corp. (NYSE: PAAS) (TSX: PAAS) ("Pan American" or the "Company") reports new drill results from the southeastern and eastern Candelaria zones of the La Colorada mine in Zacatecas, Mexico. Exploration drilling between the Cristina and San Gerónimo systems has resulted in the discovery of at least four new veins and associated contact-related replacement mineralization featuring wide mineralized intercepts with high silver, gold, and base metal grades.

"Exploration at La Colorada continues to deliver exceptional results, highlighted most recently by the discovery of at least four new high-grade veins in the southeastern Candelaria zone," said Christopher Emerson, Senior Vice President of Exploration and Geology. "With silver assays exceeding 1,000 g/t in 40% of the reported drill holes, many with attendant high base-metal and gold grades, the discovered structures indicate the potential to add to the mineral resources at La Colorada, which we look forward to reporting in our mineral reserve and mineral resource update as at June 30, 2026. Importantly, these exploration results further substantiate our revised approach for a phased development plan at La Colorada that targets the higher grade zones of the vein mine and skarn deposit."

The results summarized in this news release are from drilling completed between November 2025 and January 2026, comprising 17,774 metres in 38 holes, and build on the results previously reported in news releases dated September 8, 2025 and December 1, 2025. All intercepts are reported as estimated true widths in metres ("m"), unless indicated otherwise.

The full table of drill results, collars, plans and long sections for this period is available at https://panamericansilver.com/operations-2/silver-segment/la-colorada/ together with previously reported drill results for La Colorada.

EXPLORATION HIGHLIGHTS

San Gerónimo, Cristina and new Secondary Veins

Drilling between the Cristina and San Gerónimo systems in the southeastern Candelaria Mine has resulted in the discovery of at least four new veins and associated contact-related replacement mineralization. These features exhibit wide mineralized intercepts characterized by high silver, gold, and base metals grades. The currently defined Filomena, Nicolasa, Bernardina and Josefina veins, together with their associated splays, form a structural cluster delineated over an approximate 500-metre strike length and a 500-metre vertical extent. These veins follow similar west-northwest trends, contributing to a combined strike length of approximately 2,500 metres between the previously recognized Cristina and San Gerónimo veins.

Mineralization widens near lithological contacts with a combination of vein and contact-related replacement styles. This reinterpretation constitutes a significant advancement that continues to drive exploration success in the southeastern zone.

An aggressive infill and extensional drilling campaign and underground development program is currently underway with the intention of expanding and defining this mineralized zone. A new exploration crosscut on Level 588, planned for a total of 570 metres, had advanced 170 metres by the end of January 2026. A second crosscut on Level 448 was initiated in the first quarter of 2026 to improve zone access and drill coverage.

Drill hole result highlights from the Cristina/Filomena and San Gerónimo vein systems include:

La Chona Breccia

Drilling has delineated the new La Chona Breccia as a vertically extensive brecciated zone with estimated widths of 10 to 65 metres within the same southeastern structural corridor. The breccia hosts wide intervals of locally elevated silver and base-metal grades, further enhancing the exploration potential of the area.

Cautionary Note to US Investors

This news release has been prepared in accordance with the requirements of Canadian NI 43-101 and the Canadian Institute of Mining, Metallurgy and Petroleum Definition Standards, which differ from the requirements of U.S. securities laws. 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 public disclosure standards, including NI 43-101, differ significantly from the requirements of the SEC, and information concerning mineralization, mineral reserve and mineral resource information contained or referred to herein may not be comparable to similar information disclosed by U.S. companies. The requirements of NI 43-101 for identification of "reserves" are not the same as those of the SEC and may not qualify as "reserves" under SEC standards. Under U.S. standards, mineralization may not be classified as a "reserve" unless the determination has been made that the mineralization could be economically and legally produced or extracted at the time the reserve determination is made. U.S. investors should also understand that "inferred mineral resources" have a great amount of uncertainty as to their existence and great uncertainty as to their economic and legal feasibility. Under Canadian securities laws, estimated "inferred mineral resources" may not form the basis of feasibility or pre-feasibility studies except in rare cases.
