Pan American Silver Reports Mineral Reserves of 557 Million Ounces of Silver and 5.1 Million Ounces of Gold

All financial figures are expressed in US$ unless otherwise indicated.

VANCOUVER, Sept. 4, 2019 /CNW/ - Pan American Silver Corp. (NASDAQ: PAAS) (TSX: PAAS) ("Pan American", or the "Company") today reported that, as of June 30, 2019, its proven and probable mineral reserves are estimated to contain approximately 557 million ounces of silver and 5.1 million ounces of gold. Measured and indicated mineral resources (excluding proven and probable reserves), as of June 30, 2019, are estimated to total approximately 797 million ounces of silver and 10.6 million ounces of gold. These figures include mineral reserves and resources from the assets acquired with the Tahoe Resources Inc. ("Tahoe") transaction completed on February 22, 2019.

"Our silver reserves doubled while gold reserves tripled from reserves reported at December 31, 2018, primarily due to the additional reserves acquired from Tahoe. We now hold one of the largest silver reserves and resources in the mining industry along with substantial gold reserves," said Christopher Emerson, Pan American's Vice President of Business Development and Geology. "During the first six months of 2019, we completed 40% of the annual drilling planned for our mine sites. We are accelerating our exploration drilling in the second half the year, and plan to complete 130,000 metres of drilling".

As of June 30, 2019, inferred resources totaled approximately 303 million ounces of silver and 9.6 million ounces of gold. The majority of the increase in inferred gold resources from our December 31, 2018 update came from the acquired Tahoe assets, a significant portion of which are attributable to the Timmins exploration portfolio, which include the Juby and Fenn Gib projects.

The mineral reserve and mineral resource estimates as of June 30, 2019 do not include the polymetallic skarn discovery at the La Colorada mine. We are currently drilling with seven machines at La Colorada, and expect to release an initial resource estimate relating to the skarn at the end of 2019.

Beginning with this update, Pan American intends to report mineral reserves and mineral resources updates as of June 30 of each year, rather than as of December 31, in order to align mineral reserve and mineral resource updates with our annual mine plans and budgets.

A summary of the silver and gold mineral reserves and mineral resources as of June 30, 2019 is provided in the following tables. Complete mineral reserve and resource information for all metals, including tonnage and grades, is available at www.panamericansilver.com.

Cautionary Note to US Investors Regarding References to Mineral Reserves and Mineral Resources

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 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 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 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.
