VANCOUVER, BC--(Marketwired - September 09, 2015) - Endeavour Silver Corp. (TSX: EDR) (NYSE: EXK) announces that drilling at the Guanaceví Mine in Durango State, Mexico has extended high grade, gold-silver mineralization within three zones in the Santa Cruz vein. The Shallow Porvenir, Deep Porvenir and Santa Cruz mineralized zones are each adjacent to historic mine workings, readily accessible for future mine development.

Recent drilling highlights are summarized in the table below and include 351 grams per tonne (gpt) silver and 0.41 gpt gold (379 gpt silver equivalent (AgEq)) over 4.6 metres (m) true width, or 11.0 ounces per ton (opT) AgEq over 15.1 feet (ft), including 2,960 gpt silver and 1.8 gpt gold (3,086 gpt AgEq) over 0.23 m true width, or 90.0 opT AgEq over 0.8 ft in hole UNP9-3.

Silver equivalents are calculated at a ratio of 70:1 silver:gold.

Luis Castro, Vice President of Exploration, commented, “Each of the three new zones of mineralization are in areas of the Santa Cruz vein we thought had low potential due to some widely spaced, low grade holes drilled in previous years. These results show that high grade mineralization can be found in such areas, even adjacent to historic mine workings readily accessible for future mine development.”

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.
