Corvus drills 6.1 m of 9.94 g/t Au at North Bullfrog

Corvus Gold Inc. (“Corvus” or the “Company”) – (TSX: KOR, OTCQX: CORVF) announces results from the final 11 holes of the phase II, 26 hole resource expansion and conversion program at Mayflower Deposit, North Bullfrog Project, Nevada (Figure 1). The encouraging higher grade drill results will be incorporated into an updated Preliminary Economic Assessment (PEA) for its two stage mine development strategy at North Bullfrog later this fall and a subsequent feasibility study on the Mayflower mine for Q1 2013. The results to date continue to support the Company’s objective of establishing gold production in late 2014.

These most recent Mayflower results include near surface high-grade vein related mineralization (NB-12-164 with 9.94 g/t gold over 6.1 metres) which will be part of the early mining of the Mayflower deposit (Table 1). The high-grade gold and silver mineralization in drill hole NB-12-164 and the moderate grade intervals in holes NB-12-153 (7.6m @ 1.33 g/t gold) and NB-12-161 (12.2m @ 1.58 g/t gold) are related to adularia alteration and veining which may be the upper expression of a multistage high-grade quartz vein system similar to the high-grade mineralization found in the Yellow Jacket system 4 kilometres to the north of Mayflower.

Jeff Pontius, Corvus Gold CEO states: “These new results are highlighting the potential for the Mayflower project to provide a significant near-term financial return to Corvus Gold. In addition, the high-grade vein system that has now been intersected in two areas of the Mayflower deposit could add significant future value to the operation and our Company as we follow it down into what we believe to be a more productive high-grade zone. These results combined with the resumption of drilling at the North Area Yellow Jacket vein system will continue to show the high-grade gold and silver potential of this emerging new Nevada mining project.”

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 existing resource in February 2012.

The project currently includes numerous prospective gold targets with four (Mayflower, Sierra Blanca, Jolly Jane and Connection) containing an NI 43-101 compliant 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/.

On-site personnel at the project log and track all samples prior to sealing and shipping. Quality control is monitored by the insertion of blind certified standard reference materials and blanks into each sample shipment. All resource sample shipments are sealed and shipped to ALS Chemex in Reno, Nevada, for preparation and then on to ALS Chemex in Reno, Nevada, or Vancouver, B.C., for assaying. ALS Chemex’s quality system complies with the requirements for the International Standards ISO 9001:2000 and ISO 17025:1999. Analytical accuracy and precision are monitored by the analysis of reagent blanks, reference material and replicate samples. Finally, representative blind duplicate samples are forwarded to ALS Chemex and an ISO compliant third party laboratory for additional quality control. McClelland Laboratories Inc. prepared composites from duplicated RC sample splits collected during drilling. Bulk samples were sealed on site and delivered to McClelland Laboratories Inc. by ALS Chemex or Corvus personnel. All metallurgical testing reported here was conducted or managed by McClelland Laboratories Inc.
