Endeavour Silver Grows Its Reserves/Resources for 5th Consecutive Year, 2009 Silver Reserves Up 113%, Gold Reserves Up 87% Compared to 2008

VANCOUVER, BRITISH COLUMBIA--(Marketwire - March 3, 2010) - Endeavour Silver Corp. (TSX:EDR)(TSX:EDR.WT)(NYSE Amex:EXK)(DBFrankfurt:EJD) announces that for the fifth consecutive year, the Company has grown its combined reserves and resources in Mexico. 

Endeavour released today its updated NI 43-101 reserve and resource estimates to December 31, 2009 (see table below) for its two producing silver mines (the Guanacevi Mines in Durango State and the Guanajuato Mines in Guanajuato State) and one exploration project (the Parral project in Chihuahua State) in Mexico. The reserve and resource highlights are as follows:

2009 Reserve/Resource Highlights

  • Silver Proven and Probable Reserves up 113% to 16.6 million ounces (oz); Guanacevi 15.0 million oz and Guanajuato 1.6 million oz
  • Gold Proven and Probable Reserves up 87% to 44,000 oz; Guanacevi 22,500 oz and Guanajuato 21,500 oz
  • Silver Equivalent Proven and Probable Reserves up 103% to 19.4 million oz; Guanacevi 16.5 million oz and Guanajuato 2.9 million oz
  • Silver Indicated Resources up 21% to 23.6 million oz; Guanacevi 17.8 million oz, Guanajuato 4.3 million oz and Parral 1.5 million oz
  • Gold Indicated Resources up 35% to 119,100 oz; Guanacevi 37,100 oz, Guanajuato 38,200 oz and Parral 43,800 oz
  • Silver Equivalent Indicated Resources up 20% to 31.3 million oz; Guanacevi 20.2 million oz, Guanajuato 6.8 million oz and Parral 4.3 million oz
  • Silver Inferred Resources down 6% to 18.3 million oz; Guanacevi 9.6 million oz, Guanajuato 7.7 million oz and Parral 1.0 million oz

  • The mineral resources are exclusive of the mineral reserves
  • Mineral reserves have demonstrated economic viability whereas mineral resources do not
  • 2009 silver equivalents based on 65:1 silver:gold ratio, base metals not included as equivalents
  • 2008 silver equivalents based on 75:1 silver:gold ratio, base metals not included as equivalents
  • All assumptions used are listed at the bottom of the reserve and resource summary table

Bradford Cooke, Chairman and CEO, commented, "We are gratified to see our combined reserves and resources rise once again to a record high last year, notwithstanding our 5th consecutive year of growing production. The numbers speak to the ability and success of our exploration team at discovering new, high grade silver-gold deposits year after year within these historic Mexican silver districts."

"Last year, it was the discovery of the Porvenir Cuatro ore-body in Guanacevi and the development of the Lucero ore-body in Guanajuato helped drive our reserve/resource growth. In 2010, Endeavour will continue to focus on the organic growth of its reserves/resources in Guanacevi and Guanajuato through its ongoing strategic acquisition and exploration programs within these districts."

"However, we are also looking to new acquisitions such as the San Juanico property in the Hidalgo de Parral district, Chihuahua and the San Sebastian properties in the San Sebastian del Oeste district, Jalisco to help fuel our resource growth this year. Management will continue to evaluate M&A opportunities as a means to accelerate Endeavour's growth profile."

Barry Devlin, M.Sc., P. Geo., the Vice President of Exploration for Endeavour, is the Qualified Person who reviewed this news release and supervised the updated reserve and resource estimates. Endeavour mine and exploration personnel prepared the updated reserves and resources to December 31, 2009 for the Guanacevi and Guanajuato mines.

Endeavour retained Micon International Limited (Micon) to independently audit the updated reserves and resources for the Guanacevi and Guanajuato mines and also for the Cometa deposit on the Parral project. The Qualified Persons for Micon are William J. Lewis, B.Sc., P.Geo., Charley Murahwi, M.Sc., P.Geo, MAusIMM, Dibya Kanti Mukhopadhyay, MAusIMM, Robert J. Leader, P.Eng., Ing. Alan J. San Martin, MAusIMM and Thomas C. Stubens, M.A.Sc., P.Eng.. Micon's reports for the three projects will be filed on SEDAR before the end of March once they have been completed. 

The reserve and resource statements for the Guanacevi, Guanajuato and Parral projects were classified following the definitions and guidelines of the Canadian Institute of Mining, Metallurgy and Petroleum CIM standards and definitions on Mineral Resources and Reserves and the guidelines of NI 43-101.

Calculations or estimations inherently involve a degree of rounding and consequently introduce a margin of error.  Where these occur, they are not considered to be material.
NOTE: Mineral Resources that are not Mineral Reserves do not have demonstrated economic viability.

Endeavour Silver Corp is a small-cap silver mining company focused on the growth of its silver production, reserves and resources in Mexico. Since start-up in 2004, Endeavour has posted five consecutive years of growing silver production and resources. The organic expansion programs now underway at Endeavour's two operating silver mines in Mexico combined with its strategic acquisition program should help propel Endeavour to become the next premier mid-tier primary silver producer.
