Endeavour Silver Drilling Continues to Intersect High Grade Mineralization in the La Luz Vein on the Terronera Property in Jalisco, Mexico

VANCOUVER, BC--(Marketwired - August 15, 2017) - Endeavour Silver Corp. (NYSE: EXK) (TSX: EDR) announces that exploration drilling on the Terronera property in Jalisco State, Mexico continues to intersect high-grade, gold-silver mineralization at shallow depths within the La Luz vein.

Recent holes were drilled to test the boundaries of the current resource area (dated December 31, 2016) and successfully expanded the mineralization over a 600 metre (m) length by 250 m depth (view long section here).

Drilling highlights include two vein splays in Hole LL23 which assayed as follows:

• La Luz vein - 45 grams per tonne (gpt) silver and 16.2 gpt gold (1,180 gpt AgEq) over 1.7 m true width (34.4 opT AgEq over 5.6 feet (ft)), with an internal interval assaying 171 gpt silver and 45.2 gpt gold (3,335 gpt AgEq) over 0.2 m true width (97.2 opT AgEq over 0.7 ft); and
• La Luz HW vein - 25 gpt silver and 20.9 gpt gold (1,485 gpt AgEq) over 1.3 m true width (43.3 opT AgEq over 4.3 ft), with an internal interval assaying 44 gpt silver and 31.6 gpt gold (2,256 gpt AgEq) over 0.3 m true width (65.8 opT AgEq over 1.0 ft);

Results for seven new drill holes are summarized in the table below.

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

Bradford Cooke, CEO of Endeavour Silver, commented, "We continue to intersect encouraging results in the La Luz vein on the Terronera property. Although narrower than the Terronera vein, mineralization in the La Luz vein is much higher grade, more gold rich, and shallower in depth compared to the Terronera vein, which was the basis for the recent pre-feasibility study. Several other veins hosting surface high-grade mineralization at Terronera are also scheduled for drilling over the next two years."

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.
