Endeavour Silver Drilling Intersects High-Grade Gold-Silver Mineralization at the Bolanitos Mine in Guanajuato, Mexico


VANCOUVER, British Columbia, Dec. 01, 2020 (GLOBE NEWSWIRE) -- Endeavour Silver Corp. (NYSE: EXK) (TSX: EDR) announces that exploration drilling continues to intersect high-grade gold-silver mineralization in the Melladito and San Bernabe vein systems at the Bolanitos mine in Guanajuato, Mexico. Since drilling resumed in June, a total of 22 holes have been drilled of which 11 holes and 22 mineralized intervals returned high grades over mineable widths (view Melladito longitudinal section here).

Drilling highlights include the following intersections along the Melladito vein:

  • 12.76 grams per tonne (gpt) gold and 55 gpt silver over 4.5 metres (m) true width (1,076 gpt or 31.4 oz per ton (opT) silver equivalents (AgEq) over 14.8 feet (ft) using an 80:1 silver:gold ratio) including 0.4 m grading 43.5 gpt gold and 171 gpt silver (3,651 gpt AgEq or 106.4 opT over 1.3 ft) in hole BN-58
  • 0.51 gpt gold and 491 gpt silver over 2.7 m true width (531 gpt or 15.5 opT AgEq over 8.9 ft) including 0.4 m grading 1.74 gpt gold and 2,220 gpt silver (2,359 gpt AgEq or 68.8 opT over 1.3 ft) in hole BN-52

Drill holes BN-40, 42, 57 extend the Melladito vein mineralization further to the north and at depth, drill holes 50, 52, 58 extend the Melladito vein mineralization further to the east and near surface to possibly connect with the San Pablo mine workings, and drill holes 45, 47 extend the Melladito vein mineralization another 200 m north on the other side of the San Ramon and Providencia shafts. The Melladito mineralized zone now measures up to 200 m long by more than 250 m deep, still open at depth and to the north.

An initial three holes were drilled along the San Bernabe vein system highlighted by hole BN-59 which returned 7.91 gpt gold and 12 gpt silver over a 2.7 m true width (645 gpt AgEq or 18.8 opT over 8.9 ft).
