(All amounts expressed in US$ unless otherwise indicated)

VANCOUVER, Jan. 30, 2014 /PRNewswire/ - Pan American Silver Corp. ("Pan American" or the "Company") (PAAS: NASDAQ) (PAA: TSX) After another year of successful exploration, the La Colorada mine in Zacatecas, Mexico increased its proven and probable silver mineral reserves to 81.4 million ounces, an increase of 26% compared to the year before. Net of 2013 silver production, the mine added an estimated 16.7 million ounces of new silver reserves during the year. The updated mineral reserve and resource estimate for La Colorada as of December 31, 2013 is as follows:

In the past five years, Pan American has discovered 86 million ounces of new proven and probable silver mineral reserves at La Colorada, mainly in the NC2 and Amolillo veins. Based on this exploration success, the Company announced on December 18, 2013 ("Pan American Silver to expand its La Colorada mine") a mine expansion plan to increase estimated annual silver production from current 4.6 million ounces (2013) to 7.7 million ounces in 2018 when the full expansion project is completed.

Comprehensive details regarding this expansion project are outlined in a preliminary economic assessment technical report ("PEA") which was published today on SEDAR (Technical Report, Preliminary Economic Analysis for the Expansion of the La Colorada Mine, Zacatecas, Mexico. Effective date December 31, 2013).

Pan American will release a detailed reserve and resource update for all of its operations on February 19, 2014.

The PEA completed for the expansion project is based on La Colorada's mineral reserves and resources as of December 31, 2012 adjusted for production information available as of mid-2013. The PEA is preliminary in nature and includes inferred mineral resources that are considered too speculative geologically to have the economic considerations applied to them that would enable them to be categorized as mineral reserves. There is no certainty that the results of the PEA, including the expanded mine plan and production forecasts described herein, will be realized. Mineral resources that are not mineral reserves have no demonstrated economic viability.

The Company's decision to expand the La Colorada mine as described herein and in our press release of December 18, 2013 is not based on a feasibility study of mineral reserves demonstrating economic and technical viability and as such may be subject to increased uncertainty and risks.

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, AND

MINERAL 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, ESTIMATES INCLUDED IN THIS NEWS RELEASE HAVE BEEN BASED UPON "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. 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, ESTIMATES OF "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.
