Fortuna's San Jose Mine Updated Mine Plan and Consolidated Production Forecast

June 1, 2011: Fortuna Silver Mines Inc. (TSX: FVI / Lima Stock Exchange: FVI) is pleased to release an updated optimized mine plan for the San Jose Mine in Mexico, and a new consolidated production forecast for the Company based on the mineral reserves reported in Fortuna's news release dated April 12, 2011.

Highlights of the San Jose Mine updated mine plan:
  • 3.8 million tonnes of probable reserves with 24.5 million ounces of contained silver and 191,600 ounces of contained gold at average grades of 202 g/t Ag and 1.58 g/t Au.

  • Start-up production rate of 1,000 tpd compared to 750 tpd as stated in the pre-feasibility study (PFS) news release published in April of 2010.

  • Ramp-up to design capacity of 1,500 tpd by the fourth quarter of 2013 compared to the beginning of 2016 as stated in the PFS news release published in April of 2010.

  • Total metal production from 2011 to 2019 of 21.6 million ounces of silver and 172,815 ounces of gold.

  • Life of mine average cash cost per silver ounce net of by-product credits of US$2.84 or US$7.84 per silver equivalent ounce.

  • 3.1 million tonnes of inferred resources with 22 million ounces of contained silver and 178,000 ounces of contained gold at average grades of 222 g/t Ag and 1.80 g/t Au, not included in the reserves or the economic model. Management expects to upgrade and convert these inferred resources to reserves as is typical for an operating mine.
Jorge Ganoza, President and CEO, commented, "Our engineering team has delivered an optimized development and production plan at San Jose. We believe we are now in a position to achieve the maximum 1,500 tpd design capacity only 18 months after the start up of operations in the third quarter of this year. This should translate into higher initial silver and gold output in a very favorable metal price environment. Our start-up ore stock pile is currently at 33,000 tonnes -- just over one month of mill feed at 1,000 tpd -- and our mining team continues to build the stockpile up as we get ready for commercial operation."

2011 -- 2019 Mine Plan

The increase of the start-up production rate from 750 tpd to 1,000 tpd at San Jose has been made possible by recent underground development accessing approximately 255,000 tonnes of resources above level 1400, the first production level. The updated mine plan allows for an increase in the production and treatment rate to 1,500 tpd by the third quarter of 2013, two and a half years ahead of the PFS schedule.
