Endeavour Silver Drilling Intersects 618 gpt Silver and 3.2 gpt Gold over 21.2 metres (25.1 opT AgEq over 69.6 ft) at Terronera Project, Jalisco, Mexico

VANCOUVER, British Columbia, June 27, 2018 (GLOBE NEWSWIRE) -- Endeavour Silver Corp. (NYSE:EXK) (TSX:EDR) announces that infill drilling within the Terronera vein system on the Terronera property in Jalisco State, Mexico (see Terronera map here) has consistently intersected high grade silver-gold mineralization in nine drill holes.

The best intercept to date returned 618 grams per tonne (gpt) silver and 3.2 gpt gold over 21.2 metres (m) true width (25.1 oz per short ton (opT) silver equivalent (AgEq) over 69.6 feet (ft) in hole TR11-4 (see Terronera long section here)).

All nine drill holes were targeted to fill gaps in the drill pattern, with the goal to upgrade up to 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. Hole TR11-4 is the deepest mineralized hole drilled to date, it intersected the mineralized zone at 430 m vertical depth, and 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 should have a positive impact on our reserves and 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 infill drill program is now 60% complete, with 5,990 m drilled out of 10,000 m planned. Once the infill drill program is completed in September and full drill results are available, a revised resource estimate will be prepared, but the new results will not be in time to include in the updated pre-feasibility study anticipated to be released in August.

Management is currently awaiting a number of catalysts to advance Terronera to mine development. Engineering trade-off studies and economic modeling are now complete and an optimized pre-feasibility study is forthcoming. All required documents have been filed with Mexican government agencies for the final two environmental permits (mine dumps and tailings facilities), receipt of which is anticipated shortly. The mine and plant construction permits were issued in August, 2017. An initial debt facility to fund the new Terronera silver-gold mine is currently being prepared. Upon receipt of these catalysts, management will meet with the board to discuss a development decision.

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 is used 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 is determined by fire assay with an atomic absorption (AA) finish and silver by aqua regia digestion and ICP finish, over-limits by fire assay and gravimetric finish.
