Pan American Silver Announces Results of Joaquin Preliminary Feasibility Study

21.12.2017  |  CNW

All amounts are expressed in US$ unless otherwise indicated. This news release contains forward-looking information about expected future events and financial and operating performance of the Company. Readers should refer to the risks and assumptions set out in the "Cautionary Note Regarding Forward-Looking Statements and Information" at the end of this news release.

VANCOUVER, Dec. 21, 2017 /CNW/ - Pan American Silver Corp. (NASDAQ: PAAS; TSX: PAAS) ("Pan American", or the "Company") has finalized a preliminary feasibility study on the La Morocha deposit, which is part of the Joaquin project ("Joaquin"), located in Santa Cruz, Argentina. The study recommends the development of the La Morocha deposit as an underground mine, with processing to occur at Pan American's Manantial Espejo mill. Based on the results of the preliminary feasibility study, Pan American's Board of Directors has approved a capital investment of approximately $37.8 million to construct the La Morocha underground mine and fund activities up to the point of commercial production (excluding $3.6 million of reimbursable value-added tax ("VAT")).

The Company intends to prepare a technical report (the "Technical Report") pursuant to National Instrument 43-101 - Standards of Disclosure for Mining Projects ("NI 43-101") and file on SEDAR (www.sedar.com). The Technical Report will also be available on the Company's website (www.panamericansilver.com).

La Morocha Preliminary Feasibility Study Highlights:

  • Ore to be delivered to Manantial Espejo for processing is estimated to be 474 thousand tonnes at 721 grams per tonne of silver.
  • Life-of-mine recovered silver ounces are estimated at 8.9 million and account for 96% of the total estimated project revenue. Total recovered gold ounces are estimated at 5,100.
  • Metallurgical test work confirms that the Manantial Espejo mill is suited to process the ore from La Morocha at a slightly higher cost per tonne than the ore from Manantial Espejo. Silver and gold recovery is estimated to average 81%.
  • An estimated mine production and ore transport rate of 600 tonnes per day during peak operations.
  • The mining method will be primarily post pillar cut and fill using unconsolidated mine development waste rock for backfill.
  • Ore will be hauled to surface by mine trucks and then transported by road to the Manantial Espejo processing facility, located 145 kilometres to the south of Joaquin.
  • Development of the underground access decline ramp is scheduled to begin in the second quarter of 2018, with first ore production starting in late 2019 and running until the end of 2021.
  • The estimated $37.8 million project development capital investment (excluding $3.6 million of reimbursable VAT) is scheduled to be incurred during 2018 and 2019, and is anticipated to be funded from the cash flow generated through the Company's operating activities.
  • The base case economic estimate for La Morocha is an after-tax net present value ("NPV") of $9.1 million, using a 5% discount rate, with an after-tax internal rate of return ("IRR") of 18%, at assumed metal prices of $18.50 per ounce silver and $1,300 per ounce gold.

"Developing Joaquin is a low-risk project that enhances the value of our Manantial Espejo processing plant and infrastructure assets. The ore from La Morocha will supplement ore feed from the underground mine and stockpiles at Manantial Espejo, as well as the feed from our COSE project. We expect the combined production from these sources to contribute approximately 21 million ounces of silver to Pan American's consolidated silver production over the 2018 to 2021 time period," said Michael Steinmann, President and Chief Executive Officer of Pan American. "Furthermore, extending the life of our operations at Manantial Espejo supports our efforts to continue exploring across our large mineral concessions in the area, including the attractive exploration potential at the La Negra deposit and other prospects acquired with Joaquin."

Cautionary Note to U.S. Investors Regarding References to Mineral Resources and Mineral Reserves

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 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 ''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 an "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.
