VANCOUVER, BC --(Marketwired - March 16, 2017) - Endeavour Silver Corp. (NYSE: EXK) (TSX: EDR) announces that exploration drilling on the Terronera property in Jalisco State, Mexico continues to expand the recently discovered high-grade, silver-gold mineralized zones to greater depths within the Terronera vein and at shallow depths within the La Luz vein.

Recent drilling in the Terronera vein has expanded the main high-grade, mineralized zone down to 400 metre (m) depths, still open to depth and to the southeast (view long section here). In addition to the main zone, drilling intercepted mineralized footwall (Fw) and hangingwall (Hw) splays. In some places the splays merge to form one very thick mineralized zone (eg. Hole TR11-3). None of the drill results reported herein are included in the upcoming resource estimate and pre-feasibility study (PFS) for Terronera, and they indicate clear potential to expand resources within the Terronera vein.

Drill results from five holes* previously reported in October and December 2016, plus four new drill holes reported herein, are summarized in the table below. Highlights include 230 grams per tonne (gpt) silver and 1.8 gpt gold (359 gpt AgEq) over 16.3 m true width, or 10.5 opT AgEq over 53.5 ft, with an internal interval assaying 3,490 gpt silver and 8.9 gpt gold (4,110 gpt AgEq) over 0.3 m true width, or 119.8 opT AgEq over 1.0 ft, in hole TR11-3.

Recent drilling in the La Luz vein, located about 2.2 kilometres northeast of the Terronera vein, has expanded the new high-grade, mineralized zone over 500 m long by 250 m deep starting approximately 100 m below surface and still open to surface and to depth (view long section here). None of the drill results reported herein are included in the upcoming resource estimate and pre-feasibility study (PFS) for Terronera, and they indicate clear potential to expand resources within the La Luz vein.

Drill results from seven holes* previously reported in December 2016, plus seven new drill holes reported herein, are summarized in the table below. Highlights include 63 gpt silver and 57.0 gpt gold (4,054 gpt AgEq) over 2.2 m true width, or 118.0 opT AgEq over 7.2 ft, with an internal interval assaying 340 gpt silver and 320.0 gpt gold (22,740 gpt AgEq) over 0.3 m true width, or 663.0 opT AgEq over 1.0 ft, in hole LL-21.

Bradford Cooke, CEO of Endeavour Silver, commented, "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 Terronera. Both sets of drill results indicate the excellent exploration potential of the property. Several other veins hosting high-grade mineralization on surface north of the Terronera vein are scheduled for drilling this year. Two drill rigs are currently working on the Terronera property."

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.
