Geologic setting

Geologic description

Gold Crest Mines Inc. discovered the Pirate's Pick prospect in about 2007. The mineralization consists of a northwest-trending quartz-carbonate-sulfide-veined and brecciated zone exposed over an area about 350 meters long and 200 meters wide (Gold Crest Mines Inc., 2011 [summary]; Gold Crest Mines Inc., 2011 [geology]). The brecciated zone occurs along a fault zone. Eighteen rock chip samples from veins within the brecciated zone have an average of 1.95 grams of gold per tonne (Gold Crest Mines Inc., 2011 [gold]). The rocks in the area consist of Jurassic marine volcaniclastic sandstone, conglomerate, and argillite (Box and others, 1993).
