Corvus Gold Increases Leach Gold Recovery for Savage Valley Zone of North Area Deposit, North Bullfrog Project, Nevada

TSX: KOR  OTCQX: CORVF 

VANCOUVER, Feb. 6, 2013 /CNW/ - Corvus Gold Inc. ("Corvus" or the "Company") - (TSX: KOR, OTCQX: CORVF) announces the final results of a series of column leach tests on large diameter core sample composites from the Savage Valley area (Figure 1) of the North Area Deposit at the North Bullfrog Project, Nevada.  The final results averaged 82% gold recovery at a crush size of nominally 80% passing 19mm (-3/4 inch), which is 4% greater than the 78% gold recovery assumed in the December 6, 2012 Preliminary Economic Assessment.  The final recovery data (Table 1) shows the high gold leachability of the Savage Valley oxide material even at grades as low as 0.11 g/t. 

These new results, along with recent column leach results from the Mayflower Deposit (NR13-02, January 17, 2013) which indicated an average gold recovery of 88%, suggest potential for improved overall recovery at both the Company's Mayflower and North Area Deposit which could positively impact project economics. 

Carl Brechtel, COO of Corvus, stated: "The ongoing North Bullfrog Project gold recovery results continue to be very encouraging and offer significant upside for this attractive new Nevada mining project.  These results will be integrated with further column tests at larger crush size to help optimize cost versus recovery."
