Endeavour Silver Exploration Update: Additional Drilling Continues to Expand Three New Silver Zones in San Pedro Area, Guanacevi, Durango

Vancouver, Canada -- September 23, 2008 - Endeavour Silver Corp. (EDR: TSX, EJD: DBFrankfurt and EXK: AMEX)announces that additional exploration drilling on its San Pedro properties at the Guanacevi Mines project in Durango State, Mexico continues to expand three new zones of high grade silver-gold (lead-zinc) mineralization. 

Highlights of the latest drill results include 1,295 grams per tonne silver, 0.45 gpt gold, 1.46% lead and 2.95% zinc over 0.35 m (37.8 oz per ton silver over 1.1 feet) within a larger interval of 3.95 m grading 325 gpt silver and 0.16 gpt gold (9.5 opt silver over 13.0 feet) in drill hole NB2-1 on the C vein.

Barry Devlin, Vice President of Exploration, stated, "These new drill intercepts on the C vein and other mineralized structures at San Pedro continue to demonstrate the high grade potential of this area. We expect the 2008 drill results will allow us to delineate an initial resource for San Pedro by year end."

High grade silver-gold mineralization was intersected in an additional eight drill holes on three separate vein zones to the north of Endeavour's operating Porvenir silver mine at Guanacevi, as follows:

Endeavour acquired the San Pedro properties in late 2007 and commenced systematic drilling of the numerous veins on the property early this year in order to boost the silver-gold resources close to its Guanacevi mines and plant. In June, 2008, Endeavour announced the first new silver-gold discoveries in the district (see June, 18, 2008 news release).

The NB drill holes are important because they have defined a strong, high grade silver-gold (lead-zinc) mineralized vein over a 100m length by 100 m depth, still open in all directions. C vein is just one of six newly discovered silver mineralized zones now being drilled by Endeavour at San Pedro.

The VR drill holes continue to outline silver mineralization in both the Veronica vein and underlying manto, and the DR holes appear to be defining an extension to the old Desengano mine which produced high grade silver manto ores historically and again in the 1980's and 90's.

An additional 2,000 m of drilling is planned for the San Pedro area to year-end in order to follow up on these multiple newly discovered silver mineralized zones. 

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. (EDR: TSX, EXK: AMEX, EJD: DBFrankfurt) is a small-cap silver mining company focused on the growth of its silver production, reserves and resources in Mexico. The expansion programs now underway at Endeavour's two operating mines, Guanacevi in Durango State and Guanajuato in Guanajuato state, coupled with the Company's acquisition and exploration programs in Mexico should enable Endeavour to join the ranks of top primary silver producers worldwide.
