VANCOUVER, BC, Aug. 10, 2021 /PRNewswire/ - 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, 2021. Proven and probable mineral reserves are estimated to contain approximately 529 million ounces of silver and 4.2 million ounces of gold. Measured and indicated mineral resources (excluding proven and probable reserves) are estimated to total approximately 818 million ounces of silver and 8.3 million ounces of gold. In addition, inferred mineral resources total 460 million ounces of silver and 5.8 million ounces of gold.
Christopher Emerson, Pan American's Vice President of Business Development and Geology commented: "Despite the restrictions the COVID-19 pandemic placed on our 2020 exploration program, excellent results were achieved at many of our operations. At La Arena, we replaced
Although the Timmins' exploration program and surface drilling for the La Colorada skarn exploration continued as planned, Pan American's overall exploration activities for the year were reduced by about

Reserve and resource highlights include:
- At La Arena, we successfully replaced all of the production and increased the year-on-year mineral reserves by an estimated 60 thousand ounces of gold. This is the second consecutive year of reserve gains, and extends the mine life at La Arena by more than one year.
- At Timmins, over 200 thousand ounces of gold were added to mineral reserves, extending the mine life by more than one year. The Bell Creek mine added 68 thousand gold ounces from exploration and infill drilling. The Timmins West mine added 137 thousand gold ounces through extensional and infill drilling on the 144 Gap and Timmins deposits.
- At Morococha, 2.9 million ounces of silver were added to mineral reserves through definition of the Angela East Manto zone in the northeast portion of the mine. The new reserves are in a zone amenable to bulk mining methods.
- At Huaron, 3.9 million ounces of silver were added to mineral reserves, replacing
110% of mine production. - At La Colorada, 2.9 million ounces of silver were added to mineral reserves through exploration drilling, despite the severe limitations on underground access due to ventilation issues and COVID-19 restrictions. The Company improved ventilation in the mine in July 2021, and is now planning to increase underground exploration drilling for the second half of the year.
- At the La Colorada skarn project, the approximately 39,000 metres of infill drilling that was completed during the year, continued to return wide intercepts of mineralization. The Company will include an updated resource estimate for the skarn together with a Preliminary Economic Assessment it is aiming to disclose by the end of 2021.
- At Shahuindo, contained gold production of 193 thousand ounces and a reclassification of 146 thousand ounces of gold mineral reserves to resources contributed to a total depletion of 339 thousand ounces of gold, based on geological interpretation, cost estimates, and cut off grades.
- At the La Bolsa project, its 315 thousand ounces of gold mineral reserves and 4.5 million ounces of silver mineral reserves have been reclassified to measured and indicated mineral resources, as it remains inactive. La Bolsa is a non-core asset that the Company intends to divest. The sale of the non-core Fenn Gib project in December 2020 further reduced gold measured, indicated and inferred resources.
A summary of the silver and gold mineral reserves and mineral resources as of June 30, 2021 is provided in the following tables.

Cautionary Note Regarding Forward-Looking Statements and Information
Certain of the statements and information in this news release constitute "forward-looking statements" within the meaning of the United States Private Securities Litigation Reform Act of 1995 and "forward-looking information" within the meaning of applicable Canadian provincial securities laws. All statements, other than statements of historical fact, are forward-looking statements or information. Forward-looking statements or information in this news release relate to, among other things: the disclosure of estimated mineral reserve and mineral resource information; the ability of the Company to ramp up exploration drilling at La Colorada, and the success of such drilling; estimated mine life and any anticipated changes related thereto; the extent of, and success related to any future exploration or development programs, including with respect to the La Colorada polymetallic skarn; the accuracy of estimated mineral reserves and mineral resources; the ability of the Company to divest any non-core assets, including the La Bolsa project; expectations that metallurgical, environmental, permitting, legal, title, taxation, socio-economic, political, marketing or other issues will not materially affect estimates of mineral reserves and mineral resources.
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.
The Company cautions the reader that forward-looking statements and information involve known and unknown risks, uncertainties and other factors that may cause actual results and developments to differ materially from those expressed or implied by such forward-looking statements or information contained in this news release and the Company has made assumptions and estimates based on or related to many of these factors. Such factors include, without limitation: fluctuations in silver, gold and base metal prices; fluctuations in prices for energy inputs, labour, materials, supplies and services (including transportation); fluctuations in currency markets (such as the Canadian dollar, Peruvian sol, Mexican peso, Argentine peso and Bolivian boliviano versus the U.S. dollar); operational risks and hazards inherent with the business of mining (including environmental accidents and hazards, industrial accidents, equipment breakdown, unusual or unexpected geological or structural formations, cave-ins, flooding and severe weather); employee relations; relationships with, and claims by, local communities and indigenous populations; our ability to obtain all necessary permits, licenses and regulatory approvals in a timely manner; changes in laws, regulations and government practices in the jurisdictions where we operate, including environmental, export and import laws and regulations; legal restrictions relating to mining, including in Chubut, 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.
Cautionary Note to US Investors Regarding References to Mineral Reserves and Mineral Resources
Unless otherwise indicated, all mineral reserve and mineral resource estimates included in this news release have been prepared 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 classification system. 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 standards, including NI 43-101, differ significantly from the requirements of the United States Securities and Exchange Commission (the "SEC"), and reserve and resource information included 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 the identification of "reserves" are also not the same as those of the SEC, and 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 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 rules, estimated "inferred resources" may not form the basis of feasibility or pre-feasibility studies except in rare cases. In addition, disclosure of "contained ounces" in a mineral resource is permitted disclosure under Canadian regulations. 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 in this news release may not be comparable with information made public by companies that report in accordance with U.S. standards.
The SEC has adopted amendments to its disclosure rules to modernize the mineral property disclosure requirements for issuers whose securities are registered with the SEC under the U.S. Securities Exchange Act of 1934, as amended (the "Exchange Act"). These amendments became effective February 25, 2019 (the "SEC Modernization Rules") with compliance required for the first fiscal year beginning on or after January 1, 2021. Under the SEC Modernization Rules, the historical property disclosure requirements for mining registrants included in Industry Guide 7 under the U.S. Securities Act of 1933, as amended, will be rescinded and replaced with disclosure requirements in subpart 1300 of SEC Regulation S-K. Following the transition period, as a foreign private issuer that is eligible to file reports with the SEC pursuant to the multi-jurisdictional disclosure system (the "MJDS"), Pan American is not required to provide disclosure on its mineral properties under the SEC Modernization Rules and will continue to provide disclosure under NI 43-101. If Pan American ceases to be a foreign private issuer or loses its eligibility to file its annual report on Form 40-F pursuant to the MJDS, then Pan American will be subject to the SEC Modernization Rules, which differ from the requirements of NI 43-101.
As a result of the adoption of the SEC Modernization Rules, the SEC now recognizes estimates of "measured mineral resources", "indicated mineral resources" and "inferred mineral resources." In addition, the SEC has amended its definitions of "proven mineral reserves" and "probable mineral reserves" to be "substantially similar" to the corresponding standards under NI 43-101. While the SEC will now recognize "measured mineral resources", "indicated mineral resources" and "inferred mineral resources", U.S. investors should not assume that any part or all of the mineralization in these categories will ever be converted into a higher category of mineral resources or into mineral reserves. Mineralization described using these terms has a greater amount of uncertainty as to its existence and feasibility than mineralization that has been characterized as reserves. Accordingly, U.S. investors are cautioned not to assume that any measured mineral resources, indicated mineral resources, or inferred mineral resources that Pan American reports are or will be economically or legally mineable. Further, "inferred mineral resources" have a greater amount of uncertainty as to their existence and as to whether they can be mined legally or economically. Therefore, U.S. investors are also cautioned not to assume that all or any part of the "inferred mineral resources" exist. Under Canadian securities laws, estimates of "inferred mineral resources" may not form the basis of feasibility or pre-feasibility studies, except in rare cases. While the above terms are "substantially similar" to the standards under NI 43-101, there are differences in the definitions under the SEC Modernization Rules. Accordingly, there is no assurance any mineral reserves or mineral resources that Pan American may report as "proven mineral reserves", "probable mineral reserves", "measured mineral resources", "indicated mineral resources" and "inferred mineral resources" under NI 43-101 would be the same had Pan American prepared the reserve or resource estimates under the standards adopted under the SEC Modernization Rules.
