Endeavour Silver Expands High-Grade Silver-Gold Mineralized Zones in Terronera and La Luz Veins on the Terronera Property in Jalisco, Mexico

Drill Results

NEWS RELEASE

Endeavour Silver Expands High-Grade Silver-Gold Mineralized Zones

in Terronera and La Luz Veins on the Terronera Property in Jalisco, Mexico

Vancouver, Canada – March 16, 2017 – Endeavour Silver Corp . (NYSE: EXK, TSX: EDR)

announces that exploration drilling on the Terronera property in Jalisco St ate, 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 mineraliz ed 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 w idth, 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 w idth, or 663.0 opT AgEq over 1.0 ft, in

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 rele ase 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 ship ped 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.
