Endeavour Silver Drilling Intersects High Grade, Gold-Silver Mineralization in Three Historic Veins on Bolanitos Property, Guanajuato State, Mexico

VANCOUVER, BC--(Marketwired - August 17, 2015) - Endeavour Silver Corp. (TSX: EDR) (NYSE: EXK) announces that drilling on the Bolanitos property in Guanajuato State, Mexico has intersected high grade, gold-silver mineralization within three historic veins, San Ignacio-San Miguel, La Joya and Gabriela. Gabriela mineralization is adjacent to historic mine workings that are readily accessible for development.

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

Luis Castro, Vice President of Exploration, commented, "We are encouraged that our exploration drilling continues to find new zones of high grade mineralization at relatively shallow depths within historic veins on the Bolanitos property. The Gabriela mineralization sits adjacent to historic mine workings that should provide easy access for future mining if a large enough block of mineral can be outlined."

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.
