In February 2013, Endeavour released an initial mineral resource estimate for San Sebastian that included an indicated resource totaling 1,835,000 tonnes grading 193 gpt silver and 1.17 gpt gold containing 11.4 million oz silver and 69,300 oz gold and an inferred resource totaling 3,095,000 tonnes grading 196 gpt silver and 1.39 gpt gold containing 19.5 million oz silver and 138,100 oz gold.
The goals of the 2013 drill program are two-fold: firstly to upgrade a significant portion of the inferred resources to the indicated category and secondly, to expand the total resources by 35-50% so that a preliminary economic assessment can be completed.
All of the holes reported herein were drilled to infill the southeast half of the known mineralized zone at approximately 50 m centers. Drilling is now advancing further to the southeast to extend the high grade silver-gold zone and locate new mineralized shoots. With the Terronera vein essentially wide open along strike, and many other outcropping veins yet to be drilled, San Sebastian appears to have excellent potential for the discovery of additional high grade silver-gold mineralization.
Luis Castro, Vice President of Exploration, commented, “These excellent drill results confirm the continuity of high grade silver-gold mineralization in the Terronera vein at San Sebastian. We currently have one drill rig working to extend this mineralized zone and to discover new high grade zones. Management is of the view that San Sebastian has the potential to become a high grade, underground silver-gold mine similar in many respects to the Company’s Bolañitos mine in Guanajuato, Mexico.”
Godfrey Walton, M.Sc., P.Geo. President and COO, is the Qualified Person who reviewed and approved this news release and supervised the drilling programs on the San Sebastian property. A Quality Control sampling program of reference standards, blanks and duplicates has been instituted to monitor the integrity of all assay results. All samples were split at the San Sebastian 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 and other elements are determined by AA.
