VANCOUVER, BRITISH COLUMBIA–(Marketwired – Sept. 11, 2013) – Endeavour Silver Corp. (NYSE:EXK) (TSX:EDR) announced today that exploration drilling at the Company’s El Cubo mine in Guanajuato State, Mexico has intersected high grade gold-silver mineralization in two veins near historic mine workings in the Asunción area of the Villalpando vein system.

Drilling intersected strong mineralization in both the Villalpando vein and the Asunción vein. Drilling highlights include 375 grams per tonne (gpt) silver and 1.80 gpt gold over 4.14 metres (m) true width, or 14.1 ounces per ton (opT) silver equivalents over 13.6 feet (ft), in hole CAS-6, including 768 gpt silver and 2.69 gpt gold over 0.49 m true width, or 27.1 opT silver equivalents over 1.6 ft.

The new mineralized zones extend about 200 m long by 100 m deep, and have already been accessed by an underground crosscut from the historic workings. Fast track mine development is now underway to better define these mineralized veins and exploration drilling is expected to resume this month.

Luis Castro, Vice President of Exploration, commented, “The discovery of these two mineralized veins near the historic Asunción mine workings at El Cubo represents our first exploration success since acquiring the El Cubo mine last year, and validates our view that the exploration potential for new discoveries at El Cubo is very high.”

Godfrey Walton, M.Sc., P.Geo. President and COO, is the Qualified Person who reviewed and approved this news release and supervised the drilling programs at El Cubo. 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 El Cubo 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. Other elements are determined by AA.
