Pan American Silver extends high-grade silver zone at the La Colorada Skarn project

VANCOUVER, Nov. 1, 2022 - Pan American Silver Corp. (NASDAQ: PAAS) (TSX: PAAS) ("Pan American" or the "Company") today released results for 45 new infill and exploration drill holes totaling 34,239 metres at the Company's 100% owned La Colorada Skarn project in Zacatecas, Mexico. The results include five new drill holes that further define a zone of high-grade mineralisation around drill hole 96-03-22 that was first disclosed by the Company in a news release dated July 21, 2022. With the inclusion of these new drill holes, this area has been expanded to measure approximately 200 metres in diameter and up to 250 metres vertically.

"The five new drill holes extend a zone of mineralisation with silver and base metal grades considerably higher than the average grade in the mineral resource estimate for the Skarn deposit disclosed on September 14, 2022," said Christopher Emerson, Pan American's Vice President Business Development and Geology. "These drill holes confirm excellent grades and further drilling is planned over the coming months. In addition, step-out holes extend all three skarn zones compared to the resource estimate released in September 2022."

Pan American identified a high-grade zone of the La Colorada Skarn earlier in 2022, releasing the first drill results on July 21, 2022. The zone is now defined by 13 holes, with recent highlights such as infill drill hole D-96-06-22 with 58.30 metres at 417 g/t Ag, 11.95% Pb and 9.39% Zn, including 37.25 metres at 545 g/t Ag, 15.66% Pb and 11.83% Zn and D-96-05-22 with 39.75 metres at 334 g/t Ag, 7.06% Pb and 4.02% Zn. The mineral resource estimate Pan American released on September 14, 2022 does not include these drill results because they were drilled after the cut-off date for the resource update.

The drill results disclosed today have expanded the mineralised area of the Skarn deposit. A continuous zone of high-grade mineralisation is located between the Amolillo and NC2 veins and is related to the intersection of several east-northeast faults and northwest skarn trends. The zone extends for at least 200 metres laterally and 250 metres vertically, and has been confirmed with recent infill drill holes, including: D-96-05-22, D-96-06-22, D-96-07-22, D-96-08-22 and U-103-22. This zone is defined by a nominal drill hole intercept spacing of 30 metres.

The Central 901 mineralised zone has been extended 250 metres southeast by new drill holes: D-95-13-22, D-95-14-22, D-95-15-22, D-90-06-22, D-90-07-22, D-09-01-22, D-09-02-22, and D-90-03-22.

The East 903 mineralised zone has been extended 100 metres south by drill holes: D-29-01-22, D-29-02-22, D-29-03-22 and S-29-22. Drill hole D-95-13-22 contains 194.45 metres of 48 g/t Ag, 2.97% Pb and 4.26% Zn. The East mineralised zone also has been extended 200 metres to the northeast by new infill and extension drill holes: D-62-08-22, D-62-09-22, D-62-10-22 and D-62-11-22.

General Notes with Respect to Technical Information

Grades are shown as contained metal before mill recoveries are applied. All samples provided in this news release were assayed by ALS Global, Mexico using acid digestion with ICP finish for silver, lead, zinc, and copper. Samples sent to ALS Global were prepared in Zacatecas and Hermosillo, Mexico laboratories and sent to Vancouver B.C. Laboratory for assay. Pan American implements a quality assurance and quality control ("QAQC") program including the submission of certified standards, blanks, and duplicate samples to the laboratories. The results of the QAQC samples submitted to ALS Global demonstrate acceptable accuracy and precision. The Qualified Persons have verified the data disclosed in this news release and they are of the opinion that the sample preparation, analytical, and security procedures followed for the samples are sufficient and reliable for the purpose of any future mineral resource and mineral reserve estimates. Pan American is not aware of any drilling, sampling, recovery or other factors that could materially affect the accuracy or reliability of the data reported herein. ALS Global is independent from Pan American.

Mineral resources and mineral reserves are as defined by the Canadian Institute of Mining, Metallurgy and Petroleum.

Mineral Resources that are not Mineral Reserves have no demonstrated economic viability. No mineral reserves have yet been estimated for the Skarn deposit.

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 United States Securities and Exchange Commission (the "SEC"), and information concerning mineralization, deposits, mineral reserve and 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 mineral reserves reported by the Company in compliance with NI 43-101 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.
