Corvus Drills 25.9 m of 1.13 g/t Au at North Bullfrog
Vancouver, B.C., Corvus Gold Inc. (“Corvus” or the “Company”) – (TSX: KOR, OTCQX: CORVF) announces initial results from the first 16 holes (Figure 1) of the phase II, 23 hole resource expansion and conversion program at Mayflower Deposit, North Bullfrog Project, Nevada. This program is part of the ongoing Mayflower mine development study that is intended to be the cornerstone of a two stage mine development plan that might potentially see gold production commence in late 2014.
These most recent Mayflower results include high-grade vein related mineralization (NB-12-147 with 3.24 g/t gold over 6.1 metres) indicating the deposit may have additional higher-grade potential at depth (Table 1). Results from drill intersections through historic mine waste rock deposits, such as hole NB-12-150 with 4.6 metres of 4.17 g/t gold, further demonstrate the width potential of the vein related systems in the Mayflower deposit.
The results from the Phase II Mayflower program will be incorporated in an updated resource estimate scheduled for Q4 2012 and will also be used in the planned Mayflower feasibility study proposed to be completed in Q1 2013.

Jeff Pontius, Corvus CEO stated: “Corvus has made significant advancements on the development of the Mayflower deposit and, with the continued excellent results from the ongoing drilling, metallurgical and mine design work, Mayflower is emerging as an exceptional potential mining project. In addition, Corvus has continued with its targeting work on the Yellow Jacket high-grade gold system and will start follow up drilling on this exciting new, Nevada high-grade vein system within the month.”
About the North Bullfrog Project, Nevada
Corvus controls 100% of its North Bullfrog Project, which covers approximately 43 km² in southern Nevada just north of the historic Bullfrog gold mine formerly operated by Barrick Gold. The property package is made up of a number of leased patented federal mining claims and 461 federal unpatented mining claims. The project has excellent infrastructure, being adjacent to a major highway and power corridor. The Company and its independent consultants completed a robust positive Preliminary Economic Assessment on the current resource in February 2012.
The project currently includes numerous prospective gold targets with four (Mayflower, Sierra Blanca, Jolly Jane and Connection) collectively containing an estimated Indicated Resource of 15 Mt at an average grade of 0.37 g/t gold for 182,577 ounces of gold and an Inferred Resource of 156 Mt at 0.28 g/t gold for 1,410,096 ounces of gold (both at a 0.2 g/t cutoff), with appreciable silver credits. 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 in structural feeder zones with breccias and quartz-sulphide vein stockworks such as the Mayflower and Yellowjacket targets. The Company is actively pursuing both types of mineralization.
A video of the North Bullfrog project showing location, infrastructure access and 2010 winter drilling is available on the Company’s website at http://www.corvusgold.com/investors/video/.
