PAN AMERICAN SILVER REPLACES PROVEN AND PROBABLE

SILVER RESERVES MINED DURING 2008

Vancouver, British Columbia – February 17, 2009 – Pan American Silver Corp. (PAAS: NASDAQ; PAA: TSX) is pleased to announce the results of its 2008 year end silver reserves and resources update.

In 2008, Pan American carried out extensive exploration programs, both on its properties as well as on selected greenfield exploration projects in Peru and Mexico. In total, the Company drilled nearly 100,000 meters, resulting in the discovery and definition of 26.9 million ounces of new silver reserves, which more than replaced the 22.2 million ounces of silver consumed by mining operations in 2008. However lower base metal price assumptions coupled with higher cut off grades downgraded 8.8 million ounces from reserves to resources, and as a result, at December 31, 2008 the Company had 223.7 million ounces of silver in proven and probable reserves, down a modest 1.8% from a year ago.

At Huaron and Morococha, year end proven and probable reserves increased by 5%, or 3.2 million ounces and 10%, or 3.1 million ounces, respectively after subtracting ore mined during 2008. The Company also added 4.6 million ounces of silver to La Colorada’s reserves and 1.4 million ounces of silver to San Vicente, basically replacing all the reserves mined during 2008.

Reserve losses were experienced at Alamo Dorado due to mining and at Quiruvilca due to a combination of mining and the Company’s intention to prepare the mine for a period of care and maintenance. At Manantial Espejo, reserves remained relatively unchanged year over year.

Commenting on the 2008 exploration results, Michael Steinmann, Executive VP Geology and Exploration indicated: “I am very pleased with the results of last year’s exploration program. Our corporate reserve book has a healthy 224 million ounces of silver and gold reserves increased by 1% to over 701,000 ounces. Once again, Morococha and Huaron proved their excellent exploration potential and I strongly believe that in these large ore deposits we will continue to add reserves for many years to come. In addition, I am very excited that with Manantial Espejo’s construction complete, we will now start tapping into the tremendous exploration potential of our extensive land holdings around our newest mine”.

The following represents the changes in the Company’s estimated silver reserves, year over year:

Proven and probable silver reserves, as of December 31, 2007	227.8			million ounces
Less mined ounces (contained) during 2008		(22.2	)	million ounces
Additions due to exploration drilling during 2008	26.9			million ounces
Downgraded due to higher cut off and lower base metal prices	( 8.8		)	million ounces
-----------------------------------------------------------------------	-------
Proven and probable silver reserves, as of December 31, 2008	223.7			million ounces

During last year’s 4th quarter, the Company scaled back its greenfield exploration efforts as part of a series of cost reduction initiatives. In 2009 the Company plans to focus exploration spending on its operations. In addition, the Company plans to carry on with existing exploration programs at a limited number of highly prospective greenfield projects in Peru and Mexico.

Complete reserves and resource information for all metals, including tonnage and ore grades is available at www.panamericansilver.com.

Metal prices used to calculate December 31, 2008 ore reserves for all mines (except Quiruvilca) were: Ag: $11.00/oz, Au: $700/0z, Pb: $1,500/tonne, Cu: $4,000/tonne, Zn: $1,500/tonne.

NOTES:

Mineral Reserves and Resources have been prepared in accordance with National Instrument 43-101 – Standards of Disclosure for Mineral Projects (“NI 43-101”). This table illustrates Pan American Silver Corp's share of mineral reserves and resources. Properties in which Pan American Silver has less than 100% interest are noted next to the property name.

Mineral resource and reserve estimates for Huaron, Quiruvilca, San Vicente, La Colorada, Manantial Espejo, Alamo Dorado and Morococha were prepared under the supervision of or were reviewed by Michael Steinmann, P.Geo., Executive Vice President Geology & Exploration and Martin G. Wafforn, P.Eng., Vice President Technical Services as Qualified Persons as that term is defined in NI 43-101. Reserve/resource estimates for Silver Stockpiles were prepared in previous years by other Qualified Persons, and are adjusted for 2008 production where applicable(a). Mineral resource estimates for Hog Heaven and Waterloo based on historical third party estimates.

(a)	2007 mineral reserve and resource estimates less 2008 production

Metal Prices Used for all Mines (except Quiruvilca): Ag: $11.00/oz, Au: $700/0z, Pb: $1,500/Tonne, Cu: $4,000/Tonne, Zn: $1,500/Tonne

(b)	Metal Prices Used for Quiruvilca: Ag: $10.00/oz, Au: $725/0z, Pb: $1,300/Tonne, Cu: $3,500/Tonne, Zn: $1,150/Tonne

(ii)

The historical estimate for Hog Heaven was calculated 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 calculated 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 calculation). Michael Steinmann, P.Geo., QP for the Company, has reviewed the available data, including drill sections, surface maps, and additional supporting information sources, and believes that the historic calculation 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	Tons	oz/ton Ag	oz/ton Au
Proven reserves	2,981,690	4.88	0.018
Probable & possible reserves	904,200	10.40	0.020
Heap leach ore	316,100	1.56	0.014
Possible resources	4,500,000	2.41	0.020
Inferred resources	2,700,000	4.44	0.022

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.

(iii)

The Company believes that the historical estimate category of "proven reserves" for Hog Heaven most closely corresponds to 2,705,000 tonnes in the NI 43-101 category of "indicated resources".

(iv)	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 NI 43- 101 category of "inferred resources."

(v)

The historical estimate for Waterloo was initially calculated 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 calculated using a silver price of $5.00 per ounce(the relevant price at the time of the calculation). Michael Steinmann, P.Geo., QP for the Company, has reviewed the Technical

Evaluation Report and believes the historic calculation 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 correspond to 33,758,000 tonnes in the NI 43-101 category of "indicated resource."

CAUTIONARY NOTE TO US INVESTORS CONCERNING ESTIMATES OF MEASURED AND INDICATED 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, THESE DOCUMENTS USE 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. 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. THE REQUIREMENTS OF NI 43-101 FOR IDENTIFICATION OF ‘‘RESERVES’’ ARE NOT THE SAME AS THOSE OF THE SEC, AND RESERVES REPORTED BY THE COMPANY IN COMPLIANCE WITH NI 43-101 MAY NOT QUALIFY AS ‘‘RESERVES’’ UNDER SEC STANDARDS. 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. UNDER CANADIAN SECURITIES LAWS, DISCLOSURE MUST NOT BE MADE OF THE RESULTS OF AN ECONOMIC ANALYSIS THAT INCLUDE ‘‘INFERRED RESOURCES’’, 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. 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’’. 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.
