Endeavour Silver Infill Drilling Confirms Thick, High Grade, Silver-Gold Mineralization at Terronera Property, Jalisco State, Mexico

VANCOUVER, BC--(Marketwired - June 01, 2015) - Endeavour Silver Corp. (TSX: EDR)(NYSE: EXK) announces that infill drilling on the Terronera property in Jalisco State, Mexico continues to define high grade, silver-gold mineralization within the Terronera vein system. The main mineralized zone extends over 1,400 metres (m) in length, and is still open along strike to the southeast and down dip.

Recent drilling highlights from the Terronera vein are summarized in the table below and include 1,371 grams per tonne (gpt) silver and 1.10 gpt gold (1,448 gpt silver equivalent (AgEq)) over 6.6 m true width, or 42.2 ounces per ton (opT) AgEq over 21.6 feet (ft), including 5,420 gpt silver and 5.12 gpt gold (5,778 gpt AgEq) over 0.3 m true width, or 171.6 opT AgEq over 1.0 ft in hole TR10-4.

The Terronera vein is a large mineralized structure over 20 m wide in places that has been traced on surface for more than 3.5 kilometres (view longitudinal section here). In the mineralized zone, it often forms two parallel splays, the main vein and the hanging-wall vein. Only the main vein is shown in the longitudinal section. Silver equivalents are calculated at a ratio of 70:1 silver:gold.

Luis Castro, Vice President of Exploration, commented, “Infill drilling of the inferred resource within the Terronera vein continues to deliver consistently high grades over mineable widths with strong continuity of mineralization. One drill rig is currently working at Terronera to complete infill drilling of the main mineralized zone as part of the pre-feasibility study now underway.

“The Terronera vein holds excellent potential for additional discoveries along strike and it is the first of several prospective veins to be drilled on the Terronera property. Our goal for 2015 is to complete the pre-feasibility study by the fourth quarter. We believe Terronera has the potential to become a high-grade, underground silver-gold mine similar to our Bolañitos mine in Guanajuato.”

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.
