Endeavour Silver Reports Multiple High Grade Infill Drill Intercepts and Files Prefeasibility Study Technical Report for the Terronera Mine Project, Jalisco, Mexico

VANCOUVER, British Columbia, Sept. 19, 2018 (GLOBE NEWSWIRE) -- Endeavour Silver Corp. (NYSE: EXK, TSX: EDR) reports that infill drilling within the Terronera vein system on the Terronera property in Jalisco State, Mexico (view Terronera map here) has intersected high grade silver-gold mineralization in an additional 17 drill holes.

Drilling highlights include three high grade vein splays, totaling 12.3 metres (m) accumulated thickness, intersected in hole TR11-8, the best of which returned 1,297 grams per tonne (gpt) silver and 0.9 gpt gold over a 6.1 m true width (39.9 oz per short ton (opT) silver equivalent (AgEq) over 20.0 feet (ft) (see Terronera long section here).

All 17 drill holes were targeted to fill gaps in the drill pattern, with the goal to upgrade one million tonnes of inferred resources to measured and indicated resources so they can be included in the mine plan for Terronera, and to expand the inferred resources at depth.  Mineralization in the Terronera vein has been intersected over 1400 m long by 500 m deep, and it remains open at depth.

Drilling highlights are summarized in the following table of drill results.

Silver equivalents are calculated at a ratio of 75:1 silver: gold.  All widths are estimated true widths.

Luis Castro, Vice President, Exploration for Endeavour Silver, commented, “These infill drill results helped us meet our goal this year to increase our measured and indicated resources.  The high silver and gold grades, excellent continuity of mineralization and significant exploration upside to expand the resources reinforce our view that Terronera has the potential to become the next key asset for the Company.”

The 2018 infill drill program is now complete with 32 holes totaling 18,774 m, more than the 10,000 m originally planned but less than the revised plan of 20,000 m, as the program goals were attained. A revised resource and reserve estimate will now be prepared for release in Q1, 2019 and the mine plan will be modified to accommodate the newly defined resources. These 2018 drill results for Terronera, were not included in the 2018 updated Terronera Preliminary Feasibility Study, additionally see Endeavour Silver News Release dated June 27, 2018.
