Corvus Gold Inc. (TSX:KOR,OTCQX:CORVF) released results from the initial follow-up gravity gold recovery testing and cyanide leaching of the gravity tail material from the main vein and stockwork core of the Yellowjacket deposit at its North Bullfrog project in Nevada. The test samples represent an estimated 70 percent of the gold and 85 percent of the silver contained in Corvus’s Yellowjacket deposit estimated resource.
As quoted in the press release:
These initial results have produced high weighted recoveries for this zone, with an average of 89.2% for gold and 73% for silver (Tables 1 and 2). Of interest, 40% of the gold (weighted average) recovers via gravity separation with the concentrate reporting to just 0.06% of the processed material (a very high concentration ratio of greater than 1500 to 1).
