We remain well positioned to deliver yet another year of record silver production and record earnings. Pan American now expects to produce 18.8 million ounces of silver in 2008 and 25 million ounces of silver in 2009. ”

Financial Results

Sales during the second quarter of 2008 rose 31% from the same period in 2007 to $104 million. The increase was mainly due to higher silver prices, increased copper and lead concentrate shipments and higher doré sales from the Company’s Mexican operations.

Mine operating earnings increased to $39.3 million, a robust 25% increase from the second quarter of 2007. Increased silver production and higher realized prices for silver and other by

products, with the exception of zinc, more than offset increased cost of sales and higher depreciation charges.

Consolidated net income for the second quarter was $21.4 million or $0.26 per share, a 16% increase from 2007. Included in net income was a $3.9 million or $0.06 per share non-cash foreign exchange loss on the revaluation of future income tax liabilities. This exchange loss will have no impact on actual taxes payable. Adjusted net income2 for the quarter was $25.0 million or $0.31 per share.

Pan American’s cash flow from operations before changes in working capital increased 45% to a new quarterly record of $45.7 million, mainly as a result of increased production and higher realized silver prices.

The Company invested $66.2 million in capital expenditures during the quarter, of which $40.7 million and $13.5 million were allocated to construction of the Manantial Espejo mine and the San Vicente expansion project, respectively.

At June 30, 2008 the Company’s working capital was $214.6 million and the Company remains fully funded to complete its growth plans.

Production And Operations

Pan American produced 4.7 million ounces of silver during the second quarter of 2008. This represents an 11% increase from Q2 2007 and 0.3 million ounces more than in the first quarter of this year. Alamo Dorado, which has become the Company's highest producing silver mine, produced in excess of 1.5 million ounces, while La Colorada and Huaron both added just under one million ounces each to quarterly silver production.

Consolidated cash costs increased to $5.28 per ounce of silver. This was higher than the estimated annual forecast of $4.27 per ounce, largely as a consequence of lower than expected by-product credits and higher energy and labour costs at the Company’s Peruvian operations.

Outlook

Pan American's seven producing mines are operating as expected. Construction at Manantial Espejo, the Company's newest silver mine, was approximately 90% complete at the end of June, with start up scheduled for Q4 2008 and the expansion of San Vicente remains on schedule for completion by year end. Pan American is now forecasting silver production of 18.8 million ounces in 2008, at an average cash cost of $5.10 per ounce.

Geoff Burns added: “Our mines are operating as planned, our expansion projects are progressing well, and we continued to realize on excellent silver prices. There is no question that of late silver prices have been extremely volatile; however, the fundamentals remain positive and I am optimistic that silver will trend higher over the balance of the year leading to continuing strong financial results for Pan American.”

Mine operating earnings is a non-GAAP measure. Mine operating earnings are equal to sales less cost of sales and depreciation and amortization, which is considered to be substantially the same as gross margin.

(2)

Total cash cost and total production cost per ounce are non-GAAP measurements and investors are cautioned not to place undue reliance on it and are urged to read all GAAP accounting disclosures presented in the unaudited consolidated financial statements and accompanying footnotes.
