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

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