Endeavour Silver Drilling Extends High Grade Silver Mineralization in Alex Breccia Zone at Guanacevi Mines Project, Durango State, Mexico
Endeavour Silver Corp. (TSX: EDR)(NYSE Alternext US: EXK)(DBFrankfurt: EJD) announces that exploration drilling in late 2008 at the Guanacevi Mines project in Durango State, Mexico, was successful in extending high grade silver mineralization in the Alex Breccia mineralized zone for a total of 150 meters along strike and more than 200 meters vertically below the shallow historic mine workings.
The Alex Breccia zone is located approximately 1 km southeast of the producing Porvenir mine within the same ore-bearing structure, the Santa Cruz vein. Endeavour is currently developing underground ramp and sill access to the Alex Breccia zone in order to prepare it for the commencement of production in Q1, 2009, at which time it will become the second operating mine in the Guanacevi Mines project.
Drilling highlights include drill hole BAU-12, which intersected 670 grams per tonne silver, 0.71 gpt gold and 4.9% combined lead-zinc over 5.18 m (21.1 oz per ton silver equivalent over 17.0 feet), including 1711 gpt silver, 1.51 gpt gold and 8.19% combined lead-zinc over 1.72 m (53.2 opT silver equivalent over 5.6 ft), and drill hole BAU-16, which intersected 585 gpt silver, 0.52 gpt gold and 1.41% combined lead-zinc over 2.68 m (18.2 opT silver equivalent over 8.8 ft), including 2920 gpt silver, 2.45 gpt gold and 3.43% combined lead-zinc over 0.43 m (90.5 opT silver equivalent over 1.4 ft). Silver equivalents are calculated using a silver: gold ratio of 75: 1 and do not include lead and/or zinc.
Bradford Cooke, Chairman and CEO, stated, "We are gratified to see such strong drill results supporting our decision to push ahead with the development of the Alex Breccia zone. It will be the first new silver mine at Guanacevi since Endeavour discovered and developed the Porvenir mine to production in late 2004. Alex Breccia represents the first of three new mines scheduled for development at Guanacevi in 2009 in order facilitate Endeavour's next phase of organic production growth."
High grade silver-gold-lead-zinc mineralization at Alex Breccia has been intersected in sixteen drill holes (eight drill holes previously reported) along the Santa Cruz vein and two related splays, located to the south-east of Endeavour's operating Porvenir mine at Guanacevi, as follows:

The new high grade drill intercepts at Alex Breccia are located below the level 6 drift that extends south-east from the Santa Cruz mine workings, and the ore is being accessed for mining by driving a 300 m ramp from level 6 down into the ore-body. An updated NI 43-101 reserve and resource estimate is being prepared for the Guanacevi Mines project in Q1, 2009 and will include the Alex Breccia zone as well as other new discovery areas.

Barry Devlin, M.Sc., P.Geo. Vice President Exploration is the Qualified Person who reviewed this news release and supervised the surface drilling and sampling programs at the Parral, Guanacevi and Guanajuato Projects. A Quality Control sampling program of reference standards, blanks and duplicates has been instituted to monitor the integrity of all assay results. All core samples are split at the Parral, Guanajuato, or Guanacevi field offices and shipped to ALS-Chemex Labs, where they are dried, crushed, split and 50 gram pulp samples are prepared for analysis. Gold and silver are determined by fire assay with an atomic absorption (AA) finish and lead, zinc and copper are determined by AA.
Endeavour Silver Corp. (TSX: EDR)(NYSE Alternext US: EXK)(DBFrankfurt: EJD) is a small-cap silver mining company focused on the growth of its silver production, reserves and resources in Mexico. Since acquiring the Guanacevi Mines project in 2004, Endeavour has posted four consecutive years of aggressive silver production and reserve growth. The expansion programs now underway at Endeavour's two operating mines, Guanacevi in Durango State and Guanajuato in Guanajuato State, should facilitate Endeavour's continued growth into a mid-tier primary silver producer.
