Boanitos Mine Continued High Grade Intersects
VANCOUVER, BC - Endeavour Silver Corp. reported that exploration drilling at the Bolaûitos mine in Guanajuato State, Mexico continues to intersect high grade, silver-gold mineralization in the Asuncion area of the La Luz vein system (L-Asuncion) forming three discrete zones over an 800 meter length, still open to some extent at depth and towards surface.
Drilling highlights from the L-Asuncion area in 2014 include 329 grams per tone (gpt) silver and 4.75 gpt gold over 4.60 meters (m) true width, or 17.9 ounces per ton (opT) silver equivalents over 15.1 feet (ft), in hole LZ17-4, including 1,530 gpt silver and 9.4 gpt gold over 0.13 m true width, or 61.1 opT silver equivalents over 0.5 ft.
At a 200 gpt/m cutoff, these two mineralized zones collectively measure more than 400 m long by 250 m deep by up to 5 meters thick (see L-Asuncion longitudinal section here). Silver equivalents are calculated at a ratio of 60: 1 silver: gold.
In 2007, Endeavour identified the L-Asuncion area as one of several highly prospective target areas for the discovery of new high grade silver-gold mineralization at Bolaûitos based on old maps showing substantial mine fill of economic grade within historic mine workings at L-Asuncion. In 2012, the Company rehabilitated the old Asuncion mine shaft and gained access to map, sample and commence production of the old mine fill from the underground mine workings.
Exploration crews subsequently discovered impressive sections of mineralized vein that remained unmined in the L-Asuncion area. Surface drilling last year confirmed the presence of mineralization over 800 meters and the exploration focus for 2014 in the L-Asuncion area is to expand and better define two of the three high grade zones while tunneling progresses in a northwest direction towards them.
Luis Castro, Vice President of Exploration, commented, "We are very encouraged by both the internal continuity and precious metal grades of these mineralized zones at L-Asuncion. They remain open to some extent both down dip and up dip and represent a future production area for us at Bolanitos. Thanks to our robust free cash flow, Endeavour currently has eleven drill rigs (seven surface and four underground) working in Mexico: two at Guanacev, three at Bolaûitos, four at El Cubo and two at the emerging new high grade discovery in the Terronera vein on our San Sebastiçn project in Jalisco State."
