Vancouver, B.C… Corvus Gold Inc. (“Corvus” or the “Company”) – (TSX: KOR, OTCQX: CORVF) announces the first drill results from its 2014 exploration program at the North Bullfrog Project, Nevada. Drill hole NB-14-378 intersected a newly identified vein system with massive quartz veining enriched in native gold and silver sulphide and located 50 metres to the west of the high-grade gold-silver Yellowjacket Deposit.
Results from a near surface 9.2 metre section of the main vein that were priority assayed yielded an intercept of 17.9 g/t gold and 260 g/t silver (Table 1, Figures 1 & 2). Assays for the remainder of the hole, which includes surrounding stockwork veining similar to the Yellowjacket Deposit to the east, are pending. This represents an important addition to the vein system at Yellowjacket and illustrates the new discovery potential for additional high-grade veins even in the immediate Yellowjacket Deposit area.

Jeff Pontius, Corvus CEO, stated “This new discovery of additional Yellowjacket type, shallow, high-grade, oxide, gold and silver veins continues to reinforce the scale and magnitude of this new Nevada high-grade discovery. The new West Vein offers potential to expand the existing high-grade resource of our already compelling Yellowjacket Deposit. With good initial cyanide recoveries from preliminary metallurgical work and an aggressive program to further optimize recovery and mining plans, we are excited about the impact that an expanded high-grade resource would have on our project. The first phase of our 2014 exploration program is focused on outlining large, potentially high-grade, resource expansion areas adjacent to the Yellowjacket Deposit, and will be followed up with a resource conversion drill program that will target a new resource update later this year. This new information, linked with our district wide exploration work, has identified a number of other Yellowjacket type targets which will be tested later this spring and punctuates the significant potential to outline a new, high-grade Nevada gold deposit.”

Yellowjacket – West Vein
Geological evaluation of the results from the Yellowjacket area after the close of the 2013 drill program indicated that the fault displacement mapped along the central part of the Josh Vein structure was not enough to account for the full stratigraphic offset indicated by other drilling to the west. On this basis, it was postulated that another strand of the fault should exist west of the known Josh Vein structure. Hole NB-14-377 (assays pending) confirmed the existence of the missing structure and hole NB-14-378 encountered a massive vein on the structure while hole NB-14-379 (assays pending) encountered the typical upper stockwork veining along the structure (Figures 1 & 2). The mineralization is rich in both gold and silver with abundant silver sulphide and resembles the discovery hole NB-12-138 (72.4m @ 1.74 g/t Au & 98.7 g/t Ag including the main vein interval of 4.3m @ 20.0 g/t gold & 1,519 g/t silver).
The fact that the vein transitions into near surface stockwork veining in NB-14-379 is a part of a pattern that has now been recognized along the full strike length of the vein explored to date. It is clear that the present topographic surface is just above the top of the high-grade veins. This realization means that the vein system remains open at depth and to the south of NB-12-138 where the structure has only been tested at shallow depths. Once the new West Vein strand has been explored, the Company plans to move the drill first to the north to define the northern strike extent of the Yellowjacket system and then again to continue exploration to the south and at depth.
About the North Bullfrog Project, Nevada
Corvus controls 100% of its North Bullfrog Project, which covers approximately 68 km2 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 the newly discovered Yellowjacket vein related deposit being the highest grade with an indicated resource at a 0.3 g/t gold cut-off of 4 Mt at an average grade of 0.97 g/t gold and 5.15 g/t silver for 125,000 ounces of gold and 662,000 ounces of silver and an inferred resource of 35.6 Mt with an average grade of 0.7 g/t gold and 3.86 g/t silver for 800,000 ounces of gold and 4.4M ounces of silver. At a cutoff grade of 1 g/t gold the Yellowjacket deposit contains an indicated resource of 0.9 Mt at 2.8 g/t gold and 16.5 g/t silver for 79,000 ounces of gold and 468,000 ounces of silver and an inferred resource of 4.5 Mt of 2.44 g/t gold and 17.5 g/t silver for 355,000 ounces of gold and 2.5M ounces of silver.
In addition to the Yellowjacket deposit, the property has a large low-grade oxide resource contained in five at surface deposits (Sierra Blanca, Air Track West, Jolly Jane, Mayflower and Connection) containing an estimated Oxidized Indicated Resource of 36.7 Mt at an average grade of 0.26 g/t gold for 307,860 ounces of gold and an Oxidized Inferred Resource of 242 Mt at 0.18 g/t gold for 1,366,000 ounces of gold (both at a 0.1 g/t gold cutoff), with appreciable silver credits. Unoxidized Inferred mineral resources are 213 Mt at 0.16 g/t for 1,117,000 ounces of gold (at a 0.1 g/t gold cutoff).
