Endeavour Silver Extends High Grade Silver-Gold Mineralization in the Lana Vein at the Bolanitos Mine in Mexico; Drilling Intersects 2,300 gpt Silver and 7.1 gpt Gold Over 0.5 Meter Width

Vancouver, Canada - September 18, 2012 - Endeavour Silver Corp. (NYSE: EXK, TSX: EDR, Frankfurt: EJD) announces that exploration drilling at Endeavour's Bolanitos Mine in Guanajuato State, Mexico continues to intersect high silver and gold grades over mineable widths, extending the known mineralized zone in the Lana vein to more than 750 meters (m) long, still open for expansion. 

Drilling highlights in the Lana vein include 155 grams per tonne (gpt) silver and 2.00 gpt gold over 5.88 m true width (7.4 ounces per ton (opT) silver equivalents based on a silver: gold ratio of 50:1 over 19.3 feet (ft)) in hole LJ11-1; and 2,300 gpt silver and 7.11 gpt gold over 0.53 m true width (77.4 opT silver equivalents over 1.7 ft) in hole LJ11-2. Click here to view Longitudinal Section

Bradford Cooke, CEO and Director, commented, "Our exploration efforts continue to bear fruit around the Bolanitos mine. The Lana vein was discovered late last year when it was thought to be a splay of the La Joya vein but the drill results this year have shown it to be a separate robust mineralized vein structure. An initial resource estimate will be prepared at year-end so that the Lana vein can be brought into the 2013 mine plan for the Lucero-Karina-Fernanda-Daniela area."

"However, given the Lana vein proximity to the east of the Daniela vein, a crosscut tunnel was started in Q2, 2012 from the Daniela mine workings in order to fast-track mine access to the Lana vein. The crosscut tunnel should intersect the Lana vein this month, thereby facilitating mine development this year and production starting next year. Two drill rigs continue to work in the Bolanitos Mine area, testing other attractive drill targets such as Asuncion and Belen in 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 programs on the Bolanitos 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.
