Pan American Silver drills highest grade intercept to date on the La Colorada Skarn project

VANCOUVER, July 21, 2022 - Pan American Silver Corp. (NASDAQ: PAAS) (TSX: PAAS) ("Pan American" or the "Company") today released results for 22 new infill and exploration drill holes totaling 18,071 metres that further demonstrate the size and quality of the mineralization at the Company's La Colorada Skarn project. Infill drill hole D-96-03-22, in the western portion of the deposit, contains an extensive zone of high grade silver and base metal sulphide mineralization with an intercept of 295.5 metres at 234 g/t Ag, 6.36% Pb and 5.72% Zn, including 97.0 metres at 654 g/t Ag, 15.35% Pb and 11.38% Zn.

"Drillhole D-96-03-22 returned the highest-grade intercept from the more than 200,000 metres drilled to date on the La Colorada Skarn project," said Christopher Emerson, Pan American's Vice President Business Development and Geology. "Further infill drilling will provide tighter spacing to help define this high-grade zone, while step out drilling targets extension of the footprint to the west where the mineralization is still open."

Pan American plans to provide an update to the mineral resource estimate for the La Colorada Skarn in the third quarter of 2022. The cut-off date for the resource update was April 30, 2022, hence the drill results disclosed today will not be included in the upcoming mineral resource update.

Drill Highlights Include:

• D-96-03-22: 295.50 m at 234 g/t Ag, 0.09% Cu, 6.36% Pb and 5.72% Zn, including 97.00 m at 654 g/t Ag, 0.16% Cu, 15.35% Pb and 11.38% Zn
• D-96-04-22: 31.25 m at 216 g/t Ag, 0.05% Cu, 5.60% Pb and 4.82% Zn and 40.65 m at 99 g/t Ag, 0.03% Cu, 3.64% Pb and 4.50% Zn
• D-71-07-22: 188.50 m at 59 g/t Ag, 0.09% Cu, 3.14% Pb and 4.82% Zn, including 91.30 m at 70 g/t Ag, 0.13% Cu, 3.57% Pb and 5.86% Zn
• D-93-03-22: 117.65 m at 35 g/t Ag, 0.09% Cu, 2.75% Pb and 3.92% Zn
• D-93-04-22: 69.10 m at 48 g/t Ag, 0.06% Cu, 3.78% Pb and 4.83% Zn
• D-93-05-22: 188.70 m at 68 g/t Ag, 0.11% Cu, 4.66% Pb and 6.16% Zn, including 62.65 m at 77 g/t Ag, 0.13% Cu, 6.69% Pb and 7.58% Zn
• U-11-22: 67.70 m at 54 g/t Ag, 0.12% Cu, 3.69% Pb and 5.38% Zn
• U-18-22: 160.90 m at 82 g/t Ag, 0.16% Cu, 3.67% Pb and 6.30% Zn, including 104.60 m at 83 g/t Ag, 0.20% Cu, 5.14% Pb and 8.91% Zn and 124.20 m at 50 g/t Ag, 0.11% Cu, 2.04% Pb and 2.66% Zn, including 43.95 m at 70 g/t Ag, 0.18% Cu, 4.10% Pb and 5.05% Zn.

The drill results disclosed today have expanded the mineralized area of the Skarn deposit, as described in the following points:

• D-96-03-22 and D-96-04-22 both show high silver grades. Together with drill hole U-67-21, disclosed on November 10, 2021, which returned 114.6 metres at 133 g/t Ag, 3.60% Pb and 4.83% Zn and 16.5 metres at 228 g/t Ag, 3.36% Pb and 6.45% Zn, these holes support the interpretation of an east-west trending high grade silver zone between the Amolillo and NC2 veins that extends for at least 100 metres.
• Underground and surface drilling in the western portion of the Skarn from drill holes west of U-11-22 and S-93-21, respectively, have shown consistently wide intercepts and high grade mineralization.
• Infill drilling D-95-10/11/12-22 extending mineralization to the south of the central block showed multiple skarn and breccia style mineralization with widths up to 90 metres.
• D-71-07-22 drilled in the eastern block intercepted strong sulphide mineralization over 180 metres and further opens up exploration to the east and south. D-62-06-22 and D-62-07-22 also provided continuity of the mineralization 150 metres to the east.

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. In particular, and without limiting the generality of the foregoing, this news release uses the terms ''measured resources'', ''indicated resources'', and ''inferred resources''. U.S. investors are advised that, while such terms are recognized and required by Canadian securities laws, the SEC does not recognize them. 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. U.S. investors are cautioned not to assume that any part of a "measured resource" or "indicated resource" will ever be converted into a "reserve". U.S. investors should also understand that "inferred resources" have a great amount of uncertainty as to their existence and great uncertainty as to their economic and legal feasibility. It cannot be assumed that all or any part of "inferred resources" exist, are economically or legally mineable or will ever be upgraded to a higher category. Under Canadian securities laws, estimated "inferred resources" may not form the basis of feasibility or pre-feasibility studies except in rare cases. Disclosure of "contained ounces" in a mineral resource is permitted disclosure under Canadian securities laws. However, the SEC normally only permits issuers to report mineralization that does not constitute "reserves" by SEC standards as in place tonnage and grade, without reference to unit measures. Accordingly, information concerning mineral deposits set forth herein may not be comparable with information made public by companies that report in accordance with U.S. standards.
