Endeavour Drilling Continues to Intersect High Grade Silver-Gold Mineralization in the Karina-Fernanda-Daniela Veins at the Guanajuato Mine

VANCOUVER, BRITISH COLUMBIA--(Marketwire - June 28, 2011) - Endeavour Silver Corp. (TSX:EDR - News; NYSE:EXK - News; FRANKFURT:EJD - News) announces that exploration drilling in the Lucero South area of Endeavour's Guanajuato Mines project in Guanajuato State, Mexico continues to intersect high grades over mineable widths in the recently discovered Karina, Fernanda and Daniela veins.Drilling highlights include 404 grams per tonne (gpt) silver and 6.50 gpt gold over 7.35 meters (m) true width in the Daniela vein (20.3 ounces per ton (opT) silver equivalent based on the a silver: gold ratio of 45:1 over 24.1 feet (ft)) in hole DN-4; and 1,100 gpt silver and 3.37 gpt gold over 1.2 m in the Karina HW vein (36.5 opT silver equivalent over 3.9 ft in hole KA-31.Drill results are as follows:

Barry Devlin, Vice President Exploration for Endeavour, commented: "Our exploration drilling at Guanajuato continues to delineate high grade, gold-silver mineralization over mineable widths in the Karina-Fernanda-Daniela veins. These new vein discoveries carry higher gold grades, in some cases much higher gold grades, compared to other veins in the district. We currently have two drill rigs working in Guanajuato to continue drilling out the extents of our new finds, and we still have multiple drill targets yet to test this year."Barry Devlin, M.Sc., P.Geo. Vice President, Exploration is the Qualified Person who reviewed this news release and supervised the drilling programs on the Guanajuato Mine properties. A Quality Control sampling program of reference standards, blanks and duplicates has been instituted to monitor the integrity of all assay results. All samples were split at the Guanajuato 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 other elements are determined by AA.ENDEAVOUR SILVER CORP.BRADFORD COOKE, Chairman and CEOAbout Endeavour Silver Corp. - Endeavour Silver is a mid-cap silver mining company focused on the growth of its silver production, reserves and resources in Mexico.
