Endeavour Silver Drill Program Intersects High Grade Silver-Gold Mineralization at Lucero Extension/South Zones, Guanajuato Mine, Mexico09:03 EDT Tuesday, June 15, 2010VANCOUVER, BRITISH COLUMBIA--(Marketwire - June 15, 2010) - Endeavour Silver Corp. (TSX:EDR)(NYSE Amex:EXK)(DBFrankfurt:EJD) announces that exploration drilling south of the Bolanitos mine, part of Endeavour's Guanajuato Mines project in Guanajuato State, Mexico has now connected the Lucero Extension and Lucero South mineralized zones, thereby extending the high grade, silver-gold mineralization in the Lucero vein a full 500 meters south of the Lucero mine workings.Recent drilling highlights include a thick vein intercept grading 169 grams per tonne (gpt) silver and 2.14 gpt gold over a 9.88 meter (m) true width (4.9 oz per ton (opt) silver and 0.062 opt gold over 32.4 feet in hole LC-20, and a high grade gold intercept assaying 11.87 gpt gold and 94 gpt silver over a 3.79 m true width (0.35 opt gold and 2.74 opt silver over 12.4 ft) in hole LC-21.Assay highlights for the first twelve Lucero Extension/South drill holes were previously reported on January 26, 2010 (please click here: http://www.edrsilver.com/s/NewsReleases.asp?ReportID=382194). Assay highlights for the next nine drill holes are as follows (please click here to view: http://www.edrsilver.com/i/maps/Longitudinal_Section_Lucero_14Jun10.jpg): LUCERO DRILL RESULTS --------------------------------------------------------- Hole From Core Length True Width Ag Au -------------------------------------------------- (m) (m) (m) (g/t) (g/t) --------------------------------------------------------- LC-13 283.90 4.35 3.85 121 1.70 -------------------------------------------------- 287.10 0.85 0.77 250 3.30 --------------------------------------------------------- LC-14 274.90 4.15 3.33 343 2.02 -------------------------------------------------- 274.90 0.90 0.69 706 3.49 -------------------------------------------------- 291.50 1.95 1.65 244 3.28 -------------------------------------------------- 292.40 0.35 0.30 599 10.60 --------------------------------------------------------- LC-15 297.90 3.00 2.49 128 1.28 --------------------------------------------------------- LC-17 273.05 2.00 1.99 351 3.76 -------------------------------------------------- 273.05 0.60 0.60 736 7.87 --------------------------------------------------------- LC-18 316.30 3.95 3.52 55 3.39 --------------------------------------------------------- LC-20 276.85 10.40 9.88 169 2.14 -------------------------------------------------- 280.10 0.90 0.87 782 5.99 --------------------------------------------------------- LC-21 264.70 3.80 3.79 94 11.87 -------------------------------------------------- 266.45 0.85 0.85 169 45.20 --------------------------------------------------------- Barry Devlin, Vice President of Exploration for Endeavour, commented: "The Lucero vein is turning into a sizeable new discovery for Endeavour at Guanajuato. The initial 200 meter long Lucero discovery zone, which is currently in production, has now been extended an additional 500 meters south, the mineralization spans a 150 meter vertical panel within the vein, vein widths typically range from 2 to 10 meters and grades of samples average better than 200 gpt silver and 2 gpt gold." "As a result of this exciting new discovery, management was not only able to fast-track mine development at Lucero in 2009, we are now planning a separate new access ramp and ventilation shaft at Lucero South this year in order to accelerate production as part of our 2010 capital expansion program. Once the Lucero South zone is drilled out, we plan to move the drill rig north of the Bolanitos mine to test some attractive drill targets at the north end of the La Luz sub-district."Barry Devlin, M.Sc., P. Geo., Vice President Exploration, is the Qualified Person who reviewed this news release and supervised the drilling program at Lucero. 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 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 lead, zinc and copper are determined by AA.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 aggressive silver production, reserve and resource growth. The organic expansion programs now underway at Endeavour's two operating silver mines in Mexico combined with its strategic acquisition and exploration programs should help Endeavour achieve its goal to become the next premier mid-tier silver mining company.
