VANCOUVER, BRITISH COLUMBIA--(Marketwire - Nov. 3, 2009) - Endeavour Silver Corp. ("Endeavour" or the "Company") (TSX:EDR)(TSX:EDR.WT)(NYSE Amex:EXK)(DBFrankfurt:EJD) announces that exploration drilling program on the recently acquired Porvenir Cuatro property in the Guanacevi District, Durango, Mexico continues to intersect high grade, silver-gold mineralization along the Santa Cruz vein system.

Recent drilling highlights include 727 grams per tonne (gpt) silver and 1.51 gpt gold over a 3.44 meter (m) true width (21.2 oz per ton silver over 11.3 feet) in hole PC50-3, including 1,040 gpt silver and 2.25 gpt gold over 2.21 m true width (30.3 oz per ton silver over 7.2 ft).

The first four discovery holes were previously reported on September 1, 2009 (click here to see news release: http://www.edrsilver.com/s/NewsReleases.asp?ReportID=361815). Assay results for the next seven drill holes that returned significant high-grade silver-gold mineralization are shown in the table below.

Barry Devlin, Vice President Exploration for Endeavour commented: "This new high grade silver-gold discovery at Porvenir Cuatro is situated within the same Santa Cruz vein system that contains the Alex Breccia, Santa Cruz, Porvenir Mine and Porvenir Dos ore-bodies along strike to the south-east. Porvenir Cuatro is a good example of the excellent exploration potential still remaining in the Guanacevi district. Endeavour has several other targets to drill in Guanacevi this quarter and we can look forward to generating multiple new prospects for drilling as work progresses next year and beyond."

This newly discovered, high grade silver-gold mineralized zone has now been outlined by 11 drill holes over a 200 m long by 200 m deep area within the Santa Cruz vein, still open along strike and down dip. The Porvenir Cuatro property is located only 3 kilometers northwest of the operating Porvenir mine, part of Endeavour's Guanacevi Mines operation.

As a result of the successful drilling program at Porvenir Cuatro, management has approved a 75% increase in the 2009 exploration budget so that Porvenir Cuatro can be drilled out this quarter and moved to a resource estimate and mine planning by year-end. In addition to the 16 drill holes already completed, a further 5 drill holes are planned at Porvenir Cuatro in Q4, 2009. Endeavour now has seven drills working in Mexico, four on exploration projects and three defining the ore limits at the two mines.

Initial metallurgical test-work was carried out by SGS on four core samples to determine the amenability of Porvenir Cuatro mineralization to cyanide leaching. Four bottle roll tests returned average leach recoveries of 81.9% for silver and 79.2% for gold before optimization. Additional test-work is planned to mimic the Guanacevi plant operating conditions and optimize the leach recoveries.

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 sampling program at the Porvenir Cuatro Project. A Quality Control sampling program of reference standards, blanks and duplicates has been instituted to monitor the integrity of all assay results. All samples are split at the Guanacevi field office 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.
