Endeavour Silver’s Surface Exploration Program Outlines Prospective New Silver-Gold Veins on Terronera Property

Jun 28 2016

Endeavour Silver Corp. announces that its surface exploration program has outlined several prospective new silver-gold veins on the Terronera property in Jalisco State, Mexico. To date, mapping has extended the Terronera vein system over a 7 kilometre (km) by 7 km area and identified nine additional veins in the northern half of the property (view map).

Sampling of the Terronera vein system confirmed that high-grade, low sulphidation epithermal silver-gold mineralization is present in many of the veins. Assays of several thousand samples, including grab samples, selected samples and chip samples, returned values up to 2,880 grams per tonne (gpt) silver and up to 26.7 gpt gold.

Assay highlights from five of the new veins are summarized in the table below. These assays are intended to show peak values confirming the presence of high-grade mineralization and should not be taken as representative of the entire veins. Most of these new veins have never been tested by drilling. Silver equivalents are calculated at a ratio of 70:1 silver:gold.

La Luz	1,550	0.30 - 3.00	Quartz Vein (white-massive), with moderate to strong oxidation; some hydrothermal breccias with stockwork zones, with moderate oxidation, and some massive quartz, with weak oxidation; OxFe + OxMn;	< 0.005-26.7	0.5-951

Luis Castro, Vice President of Exploration, commented, "These excellent sample results confirm that Endeavour owns an entire vein district on the Terronera property, with many veins exhibiting high-grade silver-gold mineralization and small historic mine workings but no past exploration drilling. Currently we have two drill rigs testing the El Padre and La Luz veins."

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.
