Corvus Gold Drills 13.8 g/t Gold and 243 g/t Silver over 4.8m in new Vein at Yellowjacket
• Intersects two separate near surface high-grade gold-silver veins within hole
• Establishes lateral and vertical continuity of new West Vein high-grade system
Vancouver, B.C… Corvus Gold Inc. (“Corvus” or the “Company”) – (TSX: KOR, OTCQX: CORVF) announces additional drill results from its 2014 exploration program at the North Bullfrog Project, Nevada. Two separate veins were intersected within hole NB-14-380. Results of the two veins were prioritized, yielding intercepts of 4.2 g/t gold and 150 g/t silver over 3.6 metres in the upper vein and 13.8 g/t gold and 243 g/t silver over 4.8 metres in the main vein (Table 1, Figures 1 & 2). This hole is situated 50 metres south of NB-14-378 (NR-14-08, March 3, 2014) and demonstrates the continuity of the newly identified West Vein located 50 metres to the west of the high-grade gold-silver Yellowjacket Deposit.
Figure 1: Location of 2014 drilling at Yellowjacket. Red collar and trace indicate NB-14-380. Blue collars and traces are holes with assays pending. Blue dashed line is surface projection of Josh vein drilled in 2013. Red dashed line is projection of the new West Vein results from NB-14-380. A-B marks the location of Figure 2.
Assays are pending for the remainder of NB-14-380, which includes mineralized surrounding stockwork veining similar to the Josh Vein to the east. 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 Gold CEO states… “This new vein system which is similar to the Josh Vein immediately to the east, offers great potential to significantly expand the Yellowjacket Mineralized Zone. The location of this new high-grade mineralization within the overall larger low-grade Sierra Blanca deposit bodes well for other internal high-grade targets to be tested this year. The southern extent of this new system is completely open and could add dramatically to the overall value of the North Bullfrog project and Corvus as a whole.”

*Intercepts calculated at a 0.1 g/t gold cutoff and with up to 1 metre of internal waste.
Yellowjacket Zone
The Yellowjacket Zone has been defined by the Liberator Fault on the east and the Josh Vein Fault on the west (Figure 2). Geological evaluation of Yellowjacket Zone 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. Holes NB-14-377 (assays pending) and NB-14-378 (9.2m @ 17.9 g/t gold and 260 g/t silver) and NB-13-279 confirmed the existence of the missing structure and now hole NB-14-380 has demonstrated the continuity for 100 metres along strike. As shown in Figure 2 there is also clear evidence for a third fault to the west of the West vein structure. This fault, known as the NE50 Fault from surface geology, has a north-easterly strike which is one of the important mineralized vein orientations (Figure 1). The fact that a second vein is developed between these two faults in NB-14-380 could indicate that the NE-trending fault will also be mineralized if the structure is developed in the correct host rock. The silver to gold ratio of the West Vein system is much higher than normal for the Josh Vein farther north and is more similar to the discovery hole NB-12-138 (4.3m @ 20.0 g/t gold & 1,519 g/t silver).
As discussed previously (NR-14-08, March 3, 2014) the vein structure consistently pinches out as it approaches the surface and this is the case with NB-14-381 (Figure 2). However, the vein does continue to depth and was encountered in NB-14-382 (assays pending). This means that all potentially mineralized structures have to be tested at depth because the lack of mineralization near the surface is not a conclusive test of their potential.

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 District 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).
