Pan American Silver Increases Proven and Probable Mineral Reserves After Successful 2011 Exploration Campaign19:43 EST Wednesday, February 22, 2012VANCOUVER, BRITISH COLUMBIA--(Marketwire - Feb. 22, 2012) -(All amounts in US dollars unless otherwise stated and all production figures are approximate)Pan American Silver Corp. (TSX:PAA)(NASDAQ:PAAS) ("Pan American" or the "Company") today announced the results of its 2011 exploration activities, which more than replaced the Proven and Probable silver Mineral Reserves mined during 2011. Last year, Pan American spent $25.1 million in direct exploration, completing over 190,000 meters of diamond drilling at its seven operating mines and selected greenfield projects. Through its successful 2011 exploration program, the Company discovered 29.3 million ounces of new Proven and Probable silver Mineral Reserves, which more than replaced the 24.7 million contained ounces of silver that were mined during 2011. At December 31, 2011, Pan American had Proven and Probable silver Mineral Reserves of 235.3 million contained ounces, an increase of 2% as compared to 2010's year-end Mineral Reserves. The most notable exploration success was at the La Colorada mine, where exploration drilling added 10.6 million new ounces of silver. In 2011, La Colorada's Mineral Reserves grew by 15% from the prior year, to 44.1 million ounces of high grade Proven and Probable silver Mineral Reserves at December 31, 2011. La Colorada now has the second-largest Mineral Reserve in the Company's portfolio of assets, behind the Huaron mine, which has 60.9 million ounces of silver in Proven and Probable Mineral Reserves. In the past three years, Pan American has discovered over 39 million ounces of new Proven and Probable silver Reserves at La Colorada, mainly in sulphide mineralization of the NC2 vein. The NC2 vein remains open at depth and to the east and will continue to be the focus of further exploration this year. The sulphide mineralization at La Colorada not only contains higher silver grades, but also contains substantial base metal and gold grades. At the Alamo Dorado mine, exploration activities included infill drilling, collection of new geotechnical data, cost analysis and revision of the Mineral Resource estimation methodology. This work added 4.3 million ounces to Proven and Probable silver Reserves, which will extend Alamo Dorado's mine-life by approximately one more year. The Company plans to carry out additional work in 2012 to further optimize the mine's design and to potentially include a Phase 3 pit extension. Other highlights of the 2011 exploration campaign include the complete replacement of silver ounces mined during 2011 at Huaron, Quiruvilca and San Vicente; however, industry-wide cost pressures, particularly in Argentina and the deterioration of concentrate sales terms, specifically for silver-rich copper concentrates from the Company's Peruvian and Bolivian operations, negatively impacted the exploration results at some of our operations. The following table illustrates the changes in Pan American's estimated Proven and Probable silver Mineral Reserves, year-over-year:Proven & Probable silver Mineral Reserves as of December 31, 2010(1)230.7 million ouncesLess mined ounces (contained) during 2011(24.7) million ouncesAdditions due to exploration during 201129.3 million ouncesProven & Probable silver Mineral Reserves as of December 31, 2011(2)235.3 million ouncesPrices used to calculate Mineral Reserves for 2011 were Ag $18.00 per ounce, Au $1,100 per ounce, Pb $1,950 per tonne, Zn $1,950 per tonne and Cu $6,500 Prices used to calculate Mineral Reserves for 2012 were Ag $25.00 per ounce, Au $1,350 per ounce, Pb $1,850 per tonne, Zn $1,750 per tonne and Cu $6,500At 708.8 million ounces, Pan American's Measured and Indicated silver Mineral Resources at December 31, 2011 were practically flat year-on-year, while Inferred silver Mineral Resources grew 26.5 million ounces to 271.7 million ounces. These additions do not include the Mineral Resource estimate update currently underway at the Navidad development project, where the company conducted an extensive infill and confirmation drilling campaign during 2011. These Mineral Resources will be updated when the Company issues the results of Navidad's Feasibility Study later in 2012. Commenting on this year's exploration results, Michael Steinmann, Executive Vice President Geology and Exploration said, "2011 was another exceptional year for our brownfield exploration programs, which not only replaced the silver ounces we mined, but also increased our Proven and Probable silver Reserves. Since 2004, our continued focus on mine-site exploration has generated substantial new value by adding over 198 million ounces of Proven and Probable silver Mineral Reserves, more than replacing the 165 million ounces we mined during the same period." In 2012 Pan American expects to invest $15.5 million to complete approximately 116,000 meters of diamond drilling at its seven operating mines. In addition, the Company also plans to spend $7.8 million on greenfield exploration activities at selected properties in Mexico, Peru and Argentina.

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:CategoryTonsoz/ton Agoz/ton AuProven Reserves2,981,6904.880.018Probable & Possible Reserves904,20010.400.020Heap leach ore316,1001.560.014Possible Resources4,500,0002.410.020Inferred Resources2,700,0004.440.022However, the Company has not completed the work necessary to verify the historical estimate. Accordingly, the Company is not treating the historical estimate as NI 43-101-compliant categories of 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".(iii) 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 NI 43-101 compliant categories of 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, Quiruvilca, San Vicente, La Colorada, Manantial Espejo, Alamo Dorado, Morococha, Pico Machay and Calcatreu were prepared under the supervision or were reviewed by Michael Steinmann, P. Geo., Executive Vice-President Geology & Exploration and Martin G. Wafforn, P.
