Pan American Silver Mineral Reserves Increase to 288 Million Ounces
All financial figures are expressed in US$ unless otherwise indicated.
VANCOUVER, Feb. 20, 2018 /CNW/ - Pan American Silver Corp. (NASDAQ: PAAS; TSX: PAAS) ("Pan American", or the "Company") today reported its mineral reserves and resources as at December 31, 2017. Pan American's mineral reserves are estimated to contain approximately 288 million ounces of silver and 1.9 million ounces of gold compared with 286 million ounces of silver and 2.0 million ounces of gold at December 31, 2016.
The following table provides the changes in Pan American's estimated silver reserves year-over-year:
| Millions of ounces | ||
| Silver mineral reserves as of Dec. 31, 2016(1) | 285.8 | |
| Less: contained ounces mined during 2017 | (30.6) | |
| Plus: contained ounces replaced during 2017 | 33.2 | |
| Silver mineral reserves as of Dec. 31, 2017(2)(3) | 288.4 | |
| (1) | Prices used to estimate mineral reserves for 2016 were $18.50 per ounce of silver and $1,300 per ounce of gold, except at Manantial Espejo where $17.00 per ounce of silver and $1,200 per ounce of gold were used for planned 2017 production, reverting to $18.50 per ounce of silver and $1,300 per ounce of gold thereafter. |
| (2) | Prices used to estimate mineral reserves for 2017 were $18.50 per ounce of silver and $1,300 per ounce of gold, except at Manantial Espejo where $16.50 per ounce of silver and $1,250 per ounce of gold were used for planned 2018 production, reverting to $18.50 per ounce of silver and $1,300 per ounce of gold thereafter. |

"Our geology teams achieved another year of successful reserve replacement and resource additions, as exemplified by the newly discovered mineral reserves at our Morococha and Huaron mines in 2017," said Christopher Emerson, Pan American's Vice President Business Development and Geology. "We added about 33 million ounces of new silver mineral reserves in 2017, more than replacing ounces depleted through mining. The silver grade of the mineral reserves increased by 13% to 94 grams per tonne, in part reflecting the additions of the new high-grade properties in Argentina."
2017 Exploration Results
Pan American spent approximately $18 million on exploration drilling in 2017, efficiently achieving 100% of our planned drill metres. We completed 158 kilometres of mine and near site exploration drilling and eight kilometres of regional exploration drilling.
Morococha - added 5.8 million ounces of new silver reserves. A successful exploration drilling program was conducted in the Manuelita area of the mine that added reserves in the vicinity of the recent shaft deepening and demonstrated the potential continuity of the vein structures at depth. The minimum mining width was increased for all structures to reflect the fully mechanized mining methods applied at Morococha, which contributed to an increase in mineral reserve tonnes and reduction in silver grade.
Huaron - added 5.5 million ounces of silver for a net increase of 1.2 million contained silver ounces and 11,000 tonnes of copper in new reserves. The reserve replacement success is attributable to the continuity of the Travieso and Tapada veins, as mining progresses deeper on these structures.
La Colorada - exploration success continued, especially in the secondary NC structures, adding 7.8 million silver ounces. Reserve replacement was successful despite a reduced 2017 drill program in order to prioritize mine development work over the expansion project. With the mine expansion completed, the 2018 exploration program will focus on depth extension of the major structures.
Dolores - while the underground reserves remained stable, overall reserves were reduced by 7.9 million ounces due to open pit mining depletion and re-categorizing in situ and stock piled low-grade reserves to resources, partly offset by gains from unclassified economic material mined during 2017.
Joaquin and COSE - 7,100 metres of diamond drilling was completed, focused on the La Morocha deposit. Our preliminary feasibility study on the La Morocha deposit estimates 474 thousand tonnes of ore to be delivered to Manantial Espejo for processing, at 721 grams per tonne of silver. A total of 11.0 million ounces of silver was converted from mineral resources to mineral reserves. COSE will contribute an additional 2.2 million ounces of silver and 43 thousand ounces of gold.
Manantial Espejo - replaced 50% of mined silver ounces with the development underground to the east and at depth in the Maria East Vein.
San Vicente - in addition to 3.9 million silver reserve ounces depleted from mining, reserves were reduced by another 0.9 million ounces due to geological re-interpretation of the Union vein.
2018 Exploration Program
In 2018, Pan American plans to invest approximately $19 million in exploration drilling directed towards approximately 89 kilometres of mine and near site exploration and approximately 26 kilometres of selective regional exploration targets.

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.
