Corvus Gold Final Leach Gold Recovery Results Average 88% for Mayflower Deposit,

Vancouver, B.C……..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 Mayflower deposit at the North Bullfrog Project, Nevada.  The final results averaged 88% gold recovery at a crush size of nominally 80% passing 19mm (-3/4 inch), which represents a 10% greater gold recovery than the 78% gold recovery assumed in the December 6, 2012 Preliminary Economic Assessment (PEA).  These encouraging results suggest that the potential exists to operate the Mayflower project on a Run Of Mine (ROM) basis, although at lower recoveries than would be achieved by crushing.

The impact of ROM processing could significantly reduce both capital and operating costs per tonne for the Mayflower deposit where gold production is anticipated for late 2014.  The Company is currently conducting large ROM testing on large diameter material and working with mining consultants on optimizing blasting configurations to maximize fragmentation to assess this option.

The final recovery data (Table 1) support the high gold leachability of the Mayflower oxide material even at grades as low as 0.16 g/t.  The impact of this increased recovery data will be integrated into the Company’s upcoming Mayflower Feasibility Study scheduled for the first quarter of 2013.

Carl Brechtel, COO of Corvus, stated: “The current gold recovery results continue to be very encouraging and fully support the Mayflower deposit as an attractive mining project with potential to continue to improve.  These results, linked with the discovery of the Yellow Jacket high-grade zone in the North Area which has yet to be incorporated into the resource base, provide high potential for continued enhancement of the overall North Bullfrog project in 2013.”

In addition, a series of ROM vat leach tests are ongoing on particles at 75 mm, 150 mm and 200 mm to provide data to evaluate gold recovery at larger particle size.  These results will be integrated with further column tests at larger crush size and blasting studies to fully assess operating the Mayflower project as a ROM operation which could provide a major cost and operational benefit.

About the North Bullfrog Project, Nevada

Corvus controls 100% of its North Bullfrog Project, which covers approximately 68 square kilometres in southern Nevada just north of the historic Bullfrog gold mine formerly operated by Barrick Gold Corp.  The property package is made up of a number of private mineral leases of patented federal mining claims and 758 federal unpatented mining claims.  The project has excellent infrastructure, being adjacent to a major highway and power corridor.

The project currently includes numerous prospective gold targets with four (Mayflower, Sierra Blanca, Jolly Jane and Connection) containing an estimated Oxidized Indicated Resource of 27 Mt at an average grade of 0.28 g/t gold for 246,810 ounces of gold and an Oxidized Inferred Resource of 234.5 Mt at 0.18 g/t gold for 1,387,870 ounces of gold (both at a 0.1 g/t gold cutoff), with appreciable silver credits.  Unoxidized Inferred mineral resources are 221.6 Mt at 0.19 g/t for 1,361,000 ounces of gold (at a 0.1 g/t gold cutoff).

Mineralization occurs in two primary forms: (1) broad stratabound bulk-tonnage gold zones such as the Sierra Blanca and Jolly Jane systems; and (2) moderately thick zones of high-grade gold and silver mineralization hosted by structural zones with breccias and quartz-sulphide vein stockworks such as the Mayflower and Yellowjacket targets.  The Company is actively pursuing both types of mineralization.
