VANCOUVER, BC, Nov. 10, 2021 /CNW/ – Pan American Silver Corp. (NASDAQ: PAAS) (TSX: PAAS) ("Pan American", or the "Company") today provides results of 39 new La Colorada Skarn infill and step-out holes, all of which contain multiple skarn and breccia intercepts.

"The most recent infill and step-out holes contain some of the highest grade intercepts we have drilled in the La Colorada Skarn deposit to date and indicate potential for further expansion of the Mineral Resource in the future," said Christopher Emerson, Pan American’s Vice President Business Development and Geology.

The 2021 La Colorada Skarn drill program focused on infill drilling to increase confidence in the Mineral Resource, but also included step-out exploration drilling to evaluate lateral extensions. Over the first nine months of 2021, a total of 36,000 metres of infill drilling and 14,000 metres of exploration drilling have been completed. An additional 18,000 metres of drilling is planned for the remainder of 2021.

Considering the potential for expansion of the Mineral Resource and the high grades identified in some of the step-out holes, Pan American has decided to focus on further infill drilling and engineering studies, and as a result, will not be issuing the preliminary economic assessment ("PEA") by end of 2021, as originally anticipated. The project studies will be expanded to include additional exploration of the deposit and a review of larger scale mining methods, such as sub-level caving versus long-hole open stoping. In 2022, we intend to drill 60,000 metres to increase geological confidence, follow up on the recent highest grade intercepts, and provide further geological information for the engineering studies.

Pan American is advancing infrastructure projects for the La Colorada Skarn that will provide early benefits to the existing operation, including the construction of a refrigeration plant and the excavation of a large 5.5-metre diameter 600-metre deep concrete-lined ventilation shaft. Further, the necessary permits have been received to advance a ramp access from surface to the upper region of the Skarn deposit. The initial 2.1 km of this ramp is anticipated to be parallel dual ramps, changing to a single ramp and vertical raise bores closer to the orebody. Pan American intends to develop a surface road access to the portal location and start development of the dual ramps in 2022.

Cautionary Note to US Investors

This news release has been prepared in accordance with the requirements of Canadian National Instrument 43-101 – Standards of Disclosure for Mineral Projects (”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 Mineral 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, Canadian disclosure may use terms such as ”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.
