Corvus Gold Drilling On Yellowjacket Deposit

 

VANCOUVER - Corvus Gold Inc. reported the final assay results from the last 10 core holes drilled during the 2013 campaign at its 100% controlled North Bullfrog Project in Nevada. Exceptional high-grade results from the northernmost holes in the Yellowjacket vein system include: NB-13-372, a step out of 89 meters along strike from NB-13-370, with 27.8 meters @ 2.9 g/t gold, including 3.3 meters @ 3.9 g/t gold and 33.3 g/t silver, and NB-13-369, a step out of an additional 41 meters along strike from NB-13-372, with 37 meters @ 3.2 g/t gold including 12.9 meters @ 4.1 g/t gold and 60.6 g/t silver. The Yellowjacket system now has a drill defined strike of nearly 800 meters and remains open to the north and at depth.

Hole NB-13-370 returned the deepest intersection to date on the Yellowjacket system (170 meters down dip), which has shown a marked increase in the grade of the system.  The vein/stockwork intercept in this hole was 41.7 meters @ 4.9 g/t gold and 29.7 g/t silver, including 4.9 meters of 21.2 g/t gold and 117 g/t silver, surrounded by over 60 meters of disseminated low-grade gold-silver mineralization. The hole terminated in mineralization. This drill intercept is 125 meters down dip from the intersection in NB-13-358 (24 meters @ 1.3 g/t gold) and 73 meters down dip from NB-13-359 (65 meters @ 3 g/t gold), both of which were reported in NR13- 32, December 5, 2013). This new deeper hole opens up significant potential to extend the depth of the deposit into what appears to be a higher grade portion of the system.

An important geological feature, called the NE30 fault, intersects the Yellowjacket vein in this northern area. The fault is mineralized and, as it approaches the Yellowjacket vein structure, a thick zone of stockwork is developed between the structures as indicated by the thickness of peripheral stockwork in the hangingwall of the vein zone in hole NB-13-370 (60 meters @ 0.37 g/t gold). Hole NB-13-371, with 10 meters of 0.63 g/t gold, was drilled to confirm the location of this structural zone so it can be targeted for future high-grade veins outboard of the main Yellowjacket. The NE30 structure is consistently mineralized in holes 369, 370, 371 and 372, forming a large target.

At North Sierra Blanca, hole NB-13-375 returned 138 meters of oxide material averaging 0.26 g/t gold, thereby continuing to expand the bulk tonnage deposit and improve the confidence in the results to date. In addition, high silver intersections in hole NB-13-376 and the bottom of hole NB-13-375 have emerged as future targets for more Yellowjacket type veins at depth.

Holes NB-13-362 and NB-13-363 are PQ diameter holes drilled in the Yellowjacket deposit to confirm continuity of high-grades in larger diameter core and to acquire material for coarse crush metallurgical testing. Hole NB-13-362, with 35 meters of 4.0 g/t gold, was drilled in the center of four holes (NB-13-353, 354, 355 and 356) and has returned a similar average grade and thickness as the 4 surrounding holes. Hole NB-13-363, with 19 meters @ 3.4 g/t gold, is the twin of hole NB-12-347 which reported 14 meters @ 7.1 g/t gold. The consistency of the zone thickness is good and the variations in the grade reflect the typical variability associated with high-grade gold and silver systems and are encouraging in establishing continuity of grade with larger diameter core.
