VANCOUVER, Feb. 18, 2015 /CNW/ - Pan American Silver Corp. (PAAS: NASDAQ; PAA: TSX) ("Pan American" or the "Company") today reported on its December 31, 2014 mineral reserves and resources. Pan American's mineral reserves are estimated to contain 300 million ounces of silver and 2.32 million ounces of gold, down from the 323.5 million ounces of silver and 2.49 million ounces of gold reported a year ago. The Company used long term metal prices assumptions of $18.50 per ounce of silver and $1,250 per ounce of gold to estimate its current reserves, both lower than the long term prices used at the end of 2013. At the same time, the Company reported that its measured and indicated silver mineral resources increased 2% to 731 million ounces, while measured and indicated gold mineral resources increased 13% to 1.8 million ounces.

The following table illustrates the changes in Pan American's estimated silver mineral reserves, year-over-year:

Silver mineral reserves as of December 31, 2013(1)

323.5 million ounces

Less: Contained silver ounces mined during 2014

(32.9) million ounces

Less: Contained silver ounces recategorized

(20.1) million ounces

Plus: Contained silver ounces discovered by exploration during 2014  

29.4 million ounces

Proven & probable silver mineral reserves as of December 31, 2014(2)

299.9 million ounces

(1)

Prices used to estimate mineral reserves for 2013 were $22.00 per ounce of silver, $1,300 per ounce of gold, $1,950 per tonne of lead, $1,850 per tonne of zinc, and $6,800 per tonne of copper.

(2)

Prices used to estimate mineral reserves for 2014 were $18.50 per ounce of silver, $1,250 per ounce of gold, $2,000 per tonne of lead, $2,000 per tonne of zinc, and $6,800 per tonne of copper, except for at Alamo Dorado due to its limited remaining mine life, where metal prices of $17.00 per ounce of silver and $1,200 per ounce of gold were used.

 

Commenting on last year's exploration results, Michael Steinmann, Executive Vice President Corporate Development and Geology said, "2014 was another successful exploration year as Pan American spent $16.62 million on mine-site exploration and completed over 152.5 kilometers of diamond drilling. Through these exploration activities, the Company discovered approximately 29.6 million ounces of new silver mineral reserves, while at the same time depleting 32.9 million ounces of contained silver through production and re-categorizing 20.1 million ounces of silver, primarily due to lower prices. Steinmann continued, "It is worth noting that while reserves declined modestly, the average reserve silver grade increased by 4.1% and average reserve gold grade rose by 5.5%."

During the last 11 years, our mine-site exploration efforts have been highly successful having added over 279 million ounces of silver to our mineral reserves, excluding acquisitions, more than replacing the 257.5 million ounces of silver mined in that same period.

The La Colorada mine, which holds Pan American's largest reserves, once again returned outstanding exploration results in 2014 with a net addition of 5.5 million ounces to finish the year with a record of 86 million ounces of silver mineral reserves, a 6% increase year-on-year.

Exploration activities were restricted in certain areas at La Colorada due to the development work for the mine expansion. These restrictions will continue through 2017. Once development work is completed, it is expected that exploration efforts at La Colorada will return to higher yields. In the past six years, Pan American has discovered approximately 100 million ounces of new silver mineral reserves at La Colorada, mainly in the sulphide mineralization of the NC2 and Amolillo veins. Widely spaced, deep drilling indicates that both structures potentially extend far beyond the current mineral reserves and these zones will continue to be targeted in the Company's exploration plans after the mine expansion is completed.

The San Vicente mine replaced all of the 4.5 million ounces of silver mined during 2014 and added another 0.9 million ounces of new reserves. As expected, lower precious metal price assumptions and depletion from 2014 production more than offset reserve additions at Dolores, Huaron, and Morococha. Net of 2014 production and exploration additions, reserves at Dolores declined by 0.8 million ounces of silver and increased by 52,000 ounces of gold, due to pit optimization. At Huaron, mineral reserves declined by 0.9 million ounces of silver and at Morococha reserves declined by a modest 0.2 million ounces.

The largest change was at Manantial Espejo, where silver reserves declined by 3.4 million ounces and gold diminished by 44,000 ounces. These ounces have been moved from mineral reserves to mineral resources due to lower metal prices and may be re-classified should metal prices or cost environment improve.

In 2015, Pan American expects to invest $10.0 million to complete approximately 83 kilometers of diamond drilling at its seven operating mines. In addition, the Company also plans to spend $2.1 million on greenfield exploration activities at selected projects.

Notes:

Mineral reserves and resources are as defined by the Canadian Institute of Mining, Metallurgy and Petroleum.
Mineral resources that are not mineral reserves have no demonstrated economic viability.
Pan American does not expect these mineral reserve and resource estimates to be materially affected by metallurgical, environmental, permitting, legal, taxation, socio-economic, political, and marketing or other relevant issues.
See the Company's Annual Information Form dated March 28, 2014 for more information concerning associated QA/QC and data verification matters, the key assumptions, parameters and methods used by the Company to estimate mineral reserves and mineral resources, and for a detailed description of known legal, political, environmental, and other risks that could materially affect the Company's business and the potential development of the Company's mineral reserves and resources.
Grades are shown as contained metal before mill recoveries are applied.
Pan American reports mineral resources and mineral reserves separately. Reported mineral resources do not include amounts identified as mineral reserves.



Metal prices used for reserves at all mines were: $18.50 per ounce of silver, $1,250 per ounce of gold, $2,000 per tonne of lead, $2,000 per tonne of zinc, and $6,800 per tonne of copper., except at Alamo Dorado due to its limited remaining mine life, where metal prices of $17.00 per ounce of silver and $1,200 per ounce of gold were used.
Metal prices for Dolores and Alamo Dorado resources were $30 per ounce of silver and $1,400 per ounce of gold.
Metal prices for Manantial Espejo mineral resources were $30.00 per ounce of silver and $1,800 per ounce of gold.
Metal prices used for Navidad were $12.52 per ounce of silver and $1,100 per tonne of lead.
Metal prices used for Calcatreu were $12.50 per ounce of silver and $650 per ounce of gold
Metal prices used for La Bolsa were $14.00 per ounce of silver and $825 per ounce of gold.

The historical estimate for Hog Heaven was prepared by Gregory Hahn, Chief Geological Engineer for CoCa Mines Inc., a previous owner of the property, in a report titled "Hog Heaven Project Optimization Study" dated May 1989, prior to implementation of NI 43-101. The historical estimate was based on extensive diamond drilling, and was estimated using a silver price of $6.50 per ounce and a gold price of $400 per ounce (these were relevant prices at the time of the estimate). Michael Steinmann, P.Geo, has reviewed the available data, including drill sections, surface maps, and additional supporting information sources, and believes that the historic estimate was conducted in a professional and competent manner and is relevant for the purposes of the Company's decision to maintain its interest in this property. In the study, the historic estimate was sub-categorized as follows:




Category

However, the Company has not completed the work necessary to verify the historical estimate. Accordingly, the Company is not treating the historical estimate as current, NI 43-101-compliant mineral resources based on information prepared by or under the supervision of a QP. These historical estimates should not be relied upon.







The Company believes that the historical estimate category of "proven reserves" for Hog Heaven most closely corresponds to 2,705,000 tonnes in the CIM definition category of "indicated mineral resources".







The Company believes that the historical estimate categories of "proven & possible reserves", "heap leach ore stockpile", "possible resources" and "inferred resources" most closely correspond to 7,639,000 tonnes in the CIM definition category of "inferred mineral resources".

The historical estimate for Waterloo was initially prepared by Asarco Inc. in 1968. In September 1994 Robert J. Rodger, P.Eng., reviewed the Asarco reports and prepared a Technical Evaluation Report on the Waterloo property, prior to the implementation of NI 43-101. The Technical Evaluation Report confirmed that the historical estimate was based on reverse circulation drilling and underground sampling, and concluded the estimate was based on sound methodology. The historical estimate at Waterloo was prepared using a silver price of $5.00 per ounce (the relevant price at the time of the estimate). Michael Steinmann, P.Geo., has reviewed the Technical Evaluation Report and believes the historic estimate was conducted in a professional and competent manner and is relevant for purposes of the Company's decision to maintain its interest in the property. The Company believes that the historical estimate category of 37,235,000 tons (at 2.71 ounces per ton silver) of "measured and indicated reserves" most closely corresponds to 33,758,000 tonnes in the CIM definition category of "indicated mineral resource". However, the Company has not completed the work necessary to verify the historical estimate. Accordingly, the Company is not treating the historical estimate as current, NI 43-101 compliant mineral resources based on information prepared by or under the supervision of a QP. These historical estimates should not be relied upon.

Mineral resource and reserve estimates for Huaron, Morococha, La Colorada, Dolores, Alamo Dorado, Manantial Espejo, San Vicente, La Bolsa, Pico Machay, and Calcatreu were prepared under the supervision of, or were reviewed by Michael Steinmann, P. Geo., Executive Vice-President Corporate Development and Geology and Martin G. Wafforn, P. Eng., Vice-President Technical Services, each of whom are Qualified Persons as that term is defined in National Instrument 43-101 ("NI 43-101"). Navidad mineral resource estimates were prepared by Pamela De Mark, P. Geo., Director, Resources, formerly Sr. Consultant of Snowden Mining Industry Consultants, also a Qualified Person as that term is defined in NI 43-101. Mineral resource estimates for Hog Heaven and Waterloo are based on historical third party estimates.

Michael Steinmann and Martin Wafforn, each of whom are Qualified Persons, as the term is defined in NI 43-101, have reviewed and approved the contents of this press release.

CAUTIONARY NOTE TO US INVESTORS CONCERNING ESTIMATES OF MINERAL RESERVES AND RESOURCES

THIS NEWS RELEASE HAS BEEN PREPARED IN ACCORDANCE WITH THE REQUIREMENTS OF CANADIAN PROVINCIAL 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 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 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 PRESS 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.
