VANCOUVER, British Columbia, Nov. 9, 2007 (PRIME NEWSWIRE) --

FINANCIAL RESULTS

Pan American Silver Corp. (Nasdaq:PAAS) (TSX:PAA) today reported that consolidated net income for the third quarter of 2007 increased 46% to $23.9 million, or $0.31 per share, as compared to $16.4 million, or $0.22 per share, in the year earlier period. The Company also generated record quarterly cash flow from operations of $33.3 million, before changes in non-cash operating working capital items. The improved financial results for the quarter were primarily due to the positive contribution to earnings and cash flow from the Company's new Alamo Dorado mine, increased silver and base metal production and increased silver and lead prices. Net income in the third quarter of 2007 also benefited from the recognition of a further $2.25 million from the gain on the sale of the Company's interest in the Dukat mine in Russia.

Third quarter sales increased by 37% as compared to the year earlier period, to $87.9 million, primarily due to increased silver and base metal production and higher prices. During the third quarter the Company was able to ship all of the concentrate it produced. However for the year, concentrate shipments and therefore revenue recognition still lags production. At September 30, 2007 the Company had approximately 12,300 tonnes of concentrate inventory on hand as compared to approximately 3,700 tonnes at December 31, 2006. The Company expects to ship and record sales on all the concentrates produced in 2007 by the end of the year.

Cost of sales during the third quarter were $49.2 million, a significant increase from the $30.8 million recorded in the same period in 2006. Higher cost of sales directly reflected the inclusion of Alamo Dorado production costs, as well as the effects of industry-wide escalation in labour costs, consumable and reagent costs and stronger local currencies.

Commenting on the third quarter, Geoff Burns, President and CEO, said: "As expected, we delivered production growth, earnings growth and cash flow growth. Our construction initiatives at our two newest projects Manantial Espejo and San Vicente are progressing extremely well. By all measures Pan American had an excellent quarter, however with silver prices continuing to rally and our silver production continuing to grow strongly, I firmly believe that the best still lies ahead."

Working capital at September 30, 2007 was $207.4 million, an increase of $6.3 million from June 30, 2007. Capital expenditures in the quarter were $29.7 million, of which $16.4 million was spent on construction of the Manantial Espejo mine in Argentina and $1.8 million on the expansion project at the San Vicente mine in Bolivia.

PRODUCTION AND OPERATIONS

The Company produced 4.5 million ounces of silver in the third quarter, 6% more than in the second quarter of this year and 38% more than in the comparable period of 2006. This is the sixth consecutive quarter that Pan American has delivered silver production growth. In addition, consolidated zinc, lead and copper production increased across the board in the third quarter. All of the Company's mines demonstrated solid operating performance in the third quarter; most notable were Alamo Dorado and San Vicente where production increased 16% and 36%, respectively, as compared to the second quarter 2007.

Cash costs in the third quarter increased to $3.32 per ounce of silver, from $1.57 per ounce recorded in the comparable period in 2006. Cash costs increased as a result of increased production from Alamo Dorado, where by-product credits are limited, and general cost escalation at all of the Company's operations. Year over year, cash costs on a per tonne mined and milled basis have increased by approximately 16%, on average.

PERU

Silver production at Morococha in the third quarter of 2007 totaled 750,603 ounces, or 8% more than in the year earlier period. Despite increased mining costs associated with higher milling rates and the purchase of a small quantity of high grade ore, cash costs were negative $2.92, as byproduct credits continued to be greater than operating costs. Development of the Manto Italia ramp, which is designed to provide long term access to several untapped mining zones at Morococha continued to move forward during the quarter. This two year ramp and infrastructure project is a key component of our long term plans for Morococha.

The Huaron mine had a solid third quarter, producing 950,797 ounces of silver. Cash costs were $2.93 per ounce for the quarter, higher than the $2.32 per ounce recorded in the year earlier period primarily as a result of general cost escalation that has been previously described. Earlier this year, a mine deepening project was initiated at Huaron, an investment in the long term future of the operation. A significant portion of the highest grade reserves and resources at Huaron are located below the 250 level and this project, which includes driving a ramp below the 250 level and the deepening of a pre-existing shaft will open up a new mining area and provide access to higher grade ore for years to come.

Third quarter silver production at the Quiruvilca mine was 408,888 ounces and cash costs remained steady at $1.33 per ounce. However, production for the quarter was modestly below expectations as the operation mined lower grade ore in order to supply the mill with sufficient tonnage, while work to access deeper and higher grade ore veins in the southern area of the mine continued. The ramp is now scheduled to be completed by the end of the year.

The Silver Stockpile operation produced 117,252 ounces of silver in the third quarter at a cash cost of $2.49 per ounce.

MEXICO

Silver production at the Company's new Alamo Dorado mine steadily improved during the third quarter and the operation is now exceeding original feasibility estimates. In September the mine produced 460,000 ounces of silver, at a cash cost of $3.88, surpassing our original plans by 8%.

During the third quarter, Alamo Dorado produced 994,325 ounces of silver at a cash cost of $5.02 per ounce. Cash costs were somewhat higher than expected, primarily due to failure of one of two boilers used to preheat refinery solutions, which negatively impacted gold recoveries and associated byproduct credits. The boiler has been repaired, gold recoveries have risen and as demonstrated in September, the Company expects that costs should decline over the balance of the year.

The La Colorada mine had another excellent quarter producing 995,453 ounces of silver, 8% more than in the third quarter of 2006. It was the Company's top silver producer for the second consecutive quarter. Cash costs at La Colorada were $6.73 per ounce. Cash costs have declined compared to earlier this year, as increased production has helped offset the effects of escalation. With the operation running smoothly, attention at La Colorada has shifted to exploration, with three diamond drill rigs working at the property for most of 2007. The Company looks forward to providing a formal update on the positive results that have been achieved from this program when it publishes a new reserve and resource statement in early 2008.

ARGENTINA

Mining and construction activities continued to ramp up at the Manantial Espejo project in Argentina. On the mining side, the Melissa and Maria underground ramps have advanced a total of 1,129 meters and we have intersected both veins as modeled. Pre-stripping of the Karina Union and Maria pits is ahead of schedule with more than 1.6 million tonnes moved to the end of September.

Construction activities have been accelerating rapidly with over 500 Pan American and contractor employees now on site. The tailings dam has been completed, concrete placement is 56% complete, the administration and laboratory buildings have been completed and should be occupied by the end of November and steel erection for the main leaching and thickening tanks is in progress. At the end of the third quarter, project expenditures totaled $72.8 million with total project commitments at $93.9 million. To date, construction is on budget with mechanical completion scheduled for May of 2008; however, possible delays in equipment deliveries and contractor timing is putting this schedule under pressure. Manantial Espejo is expected to produce an average of 4.1 million ounces of silver and 60,000 ounces of gold annually.

BOLIVIA

Mining and mine expansion activities continued throughout the third quarter at the high grade silver-zinc San Vicente mine. The mine produced 236,412 ounces of silver at a cash cost of $5.21 per ounce.

Mine development is moving ahead as planned with the advance of the Litoral ramp approaching 400 meters. Plant construction and related infrastructure expansion has been initiated. Civil work, consisting of site clearing for the plant and associated facilities and the building of roads was approximately 75% complete at the end of the quarter. The construction camp is being finished and should be ready for occupancy shortly, detailed engineering is nearing completion and all the major long lead time equipment has been ordered. The San Vicente expansion project is still in its early stages, but is off to a reasonable start.

The expansion project should be completed at the end of 2008 at a total cost of approximately $40.5 million and when completed San Vicente should produce an average of 2.8 million ounces of silver per year for at least the first five years of full production.

Pan American Silver's mission is to be the largest and lowest cost primary silver mining company globally, and to achieve this by constantly increasing its low cost silver production and its silver reserves. Pan American has delivered 12 consecutive years of production growth and expects to continue this trend in 2007 as silver production is on track to increase by 31% to 17 million ounces in 2007, then increase to over 25 million ounces by 2009.

 (1) The Company reports the non-GAAP cash cost per ounce of payable
     silver in order to manage and evaluate operating performance at
     each of the Company's mines. The measure is widely used in the
     silver mining industry as a benchmark for performance, but does
     not have standardized meaning. To facilitate a better
     understanding of this measure as calculated by the Company, we
     have provided a detailed reconciliation of this measure to our
     cost of sales, as shown in our unaudited Consolidated Statement
     of Operations for the period, which can be found on page 6 of the
     MD&A.
