Endeavour Silver Drilling Continues to Intersect High Grade Silver-Gold Mineralization in Terronera Vein at San Sebastian Project, Jalisco, Mexico

VANCOUVER, BRITISH COLUMBIA--(Marketwired - Aug. 27, 2014) - Endeavour Silver Corp. (NYSE:EXK)(TSX:EDR) announces that exploration drilling at the San Sebastián project in Jalisco State, Mexico continues to intersect high grade, silver-gold mineralization in the Terronera vein system. The main mineralized zone now extends over 1,400 metres (m) in length, still wide open along strike and to some extent down dip.

Drilling highlights to date this year from the Terronera vein include 126 grams per tonne (gpt) silver and 4.02 gpt gold (367 gpt silver equivalent (AgEq)) over 12.76 m true width, or 10.7 ounces per ton (opT) AgEq over 41.9 feet (ft), in hole TR23-1, including 213 gpt silver and 12.25 gpt gold (948 gpt AgEq) over 0.90 m true width, or 27.6 opT AgEq over 3.0 ft. Silver equivalents are calculated at a ratio of 60: 1 silver: gold. Positive drill results for the year to date are summarized in the following table:

The Terronera vein is a large structure up to 16 m wide that has been traced on surface for more than 2.8 kilometres. In the mineralized zone, it often forms two parallel splays, the main vein and the hanging-wall vein. Only the main vein is shown in the longitudinal section.

Drill holes TR4S-1 and TR23-1 are 100 m step-out holes that clearly show the mineralized zone is open to the southeast and northwest. Drill holes TR4S-1, TR17-2 and TR22-2 returned low core recoveries due to broken ground, and holes TR20-3 and TR21-1 bottomed in old mine workings where high grade ore was previously mined.

Luis Castro, Vice President of Exploration, commented, "We are encouraged by the strong continuity, robust thicknesses and high grades of the mineralization intersected by these drill holes. Endeavour currently has three drill rigs working at San Sebastián to expand and delineate the mineralized zone in advance of a new resource estimate and preliminary economic assessment expected in the fourth quarter.

"Last year, we completed our environmental baseline study and filed our mine development permit application. Our goal for 2014 is to complete enough work to consider a mine development decision by year-end. Management is of the view that San Sebastián has the potential to become a high grade, underground silver-gold mine similar to the Company's Bolañitos mine in Guanajuato, Mexico."

Godfrey Walton, M.Sc., P.Geo., Endeavour's President and COO, is the Qualified Person who reviewed and approved this news release and supervised the drilling programs in Mexico. 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 local 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.
