VANCOUVER, BC, Aug. 5, 2020 /CNW/ – Pan American Silver Corp. (NASDAQ: PAAS) (TSX: PAAS) (“Pan American”, or the “Company”) today reported its estimated mineral reserves and resources as of June 30, 2020. Proven and probable mineral reserves are estimated to contain approximately 550 million ounces of silver and 5.2 million ounces of gold. Measured and indicated mineral resources (excluding proven and probable reserves) are estimated to total approximately 806 million ounces of silver and 9.4 million ounces of gold. In addition, inferred resources, including the La Colorada polymetallic skarn deposit, total 458 million ounces of silver and 6.9 million ounces of gold.

June 30, 2020. Particularly significant gains were realized at La Colorada, La Arena and Shahuindo,” said Christopher Emerson, Pan American’s Vice President of Business Development and Geology. “Through 200,000 metres of drilling from July 2019 to June 2020, we were able to add 22.1 million ounces of silver and 719 thousand ounces of gold to our proven and probable mineral reserves.”

⁽²⁾ Please refer to the complete mineral reserve and resource table at the end of this news release for more information.

At La Colorada, exploration drilling led to an increased inferred mineral resource estimate for the skarn deposit of 100.4 million tonnes, containing an estimated 141.0 million ounces of silver, as disclosed on August 4, 2020. In the producing area of the La Colorada mine, we discovered an estimated 10.0 million ounces of silver in proven and probable mineral reserves, more than replacing the 7.2 million ounces mined during the year.

At Shahuindo, infill drilling led to the discovery of an estimated 406 thousand ounces of gold mineral reserves and 7.2 million ounces of silver mineral reserves, nearly twice the ounces mined over the 12-month period ended June 30, 2020.

At La Arena, we successfully replaced all of the production and increased the year on year mineral reserves by an estimated 37 thousand ounces of gold, extending mine life by more than one year.

At Timmins, the Bell Creek mine succeeded in replacing 100% of production, primarily through tightly spaced definition drilling, while Timmins West replaced 70% of production. Exploration drilling laterally and to depth at Bell Creek extended known veins and increased inferred mineral resources by an estimated 104 thousand ounces of gold.

At Huaron, drilling of the major vein structures added an estimated 5.9 million ounces of silver mineral reserves.

La Colorada skarn and Navidad deposits are estimated to contain 141 and 119 million ounces of inferred silver resources, respectively. The sale of the Juby exploration property was completed in June 2020, which led to a subsequent reduction in the indicated and inferred gold mineral resources.

June 30, 2020 is provided in the following tables.

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

Pan American reports mineral resources and mineral reserves separately. Reported mineral resources do not include amounts identified as mineral reserves. Mineral resources that are not mineral reserves have no demonstrated economic viability.

Pan American does not expect these mineral reserve and mineral resource estimates to be materially affected by metallurgical, environmental, permitting, legal, taxation, socio-economic, political, and marketing or other relevant issues.

These forward-looking statements and information reflect the Company’s current views with respect to future events and are necessarily based upon a number of assumptions that, while considered reasonable by the Company, are inherently subject to significant operational, business, economic and regulatory uncertainties and contingencies. These assumptions include: our mineral reserve and mineral resource estimates and the assumptions upon which they are based; ore grades and recoveries; prices for silver, gold, and base metals remaining as estimated; currency exchange rates remaining as estimated; capital, decommissioning and reclamation estimates; prices for energy inputs, labour, materials, supplies and services (including transportation); all necessary permits, licenses and regulatory approvals for our operations are received in a timely manner; our ability to comply with environmental, health and safety laws; and that the COVID-19 pandemic, or other pandemics, do not materially impact underlying assumptions used in estimating mineral reserves and mineral resources, such as prices, the costs and availability of necessary labour, energy, supplies, materials and services, and exchange rates, among other things. The foregoing list of assumptions is not exhaustive.

Argentina, and in Guatemala; risks relating to expropriation; diminishing quantities or grades of mineral reserves as properties are mined; increased competition in the mining industry for equipment and qualified personnel; and those factors identified under the caption “Risks Related to Pan American’s Business” in the Company’s most recent form 40-F and Annual Information Form filed with the United States Securities and Exchange Commission and Canadian provincial securities regulatory authorities, respectively. Although the Company has attempted to identify important factors that could cause actual results to differ materially, there may be other factors that cause results not to be as anticipated, estimated, described or intended. Investors are cautioned against undue reliance on forward-looking statements or information. Forward-looking statements and information are designed to help readers understand management’s current views of our near and longer term prospects and may not be appropriate for other purposes. The Company does not intend, nor does it assume any obligation to update or revise forward-looking statements or information, whether as a result of new information, changes in assumptions, future events or otherwise, except to the extent required by applicable law.

This news release has been prepared in accordance with the requirements of Canadian securities laws, which differ from the requirements of U.S. securities laws. Unless otherwise indicated, all mineral reserve and mineral resource estimates included in this news release have been disclosed in accordance with 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. 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, 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 Pan American 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.
