Corvus Gold Inc. (TSX:KOR, OTCQX:CORVF) announced additional exploration results from its 10,260 metre 2015 exploration program which tested both new and resource expansion targets across the North Bullfrog property.
- Savage Target: 3.1m @ 2.1 g/t Gold & 178 g/t Silver
- Rhyolite Zone: 6.1m @ 1.9 g/t Gold & 10 g/t Silver
- North YellowJacket Zone: 3.1 @ 1.25 g/t Gold & 2 g/t Silver
Savage Target: Three holes were drilled in the main Savage target immediately adjacent to the southern portion of the Sierra Blanca deposit. Thick oxide zones of mineralization were identified and at a depth of ~350 metres in hole NB-15-273 a higher grade (3.1m @ 2.05 g/t gold and 178 g/t silver), copper rich zone was intersected with textures indicative of a higher temperature mineral system.
In addition to copper grades up to 0.2%, the intercepts had high antimony, tellurium and arsenic numbers, suggesting a possible porphyry/intrusive association. A review of the drill chips from NB-15-274 and NB-11-95 has confirmed the presence of multiple aphanitic-fine porphyritic dacite dikes, suggesting the presence of an intrusive center at depth beneath northern Savage Valley. All three holes at Savage also returned broad zones of low grade oxide mineralization.
Rhyolite Zone: Two drill holes were completed on the Rhyolite Zone. NB-15-266 drilled near hole NB-15-267 had recovery problems through the zone and was not completed to planned depth. Although the hole experienced recovery problems it still returned encouraging grades, although not to the level of hole NB-15-267 (10.7m @ 3.47 g/t Au & 3.6 g/t Ag).
NB-15-276 was a ~30 metres step out drill hole to the northeast. This step-out hole indicates the system is narrowing to the NE with gold grade dropping off and silver grade increasing in that direction (best hit 4.6m @ 10.6 g/t silver). These results are now vectoring future exploration to the SW along the main Rhyolite trend.
North YellowJacket Zone: Four holes drilled in the North YellowJacket extension target 75 and 150 metres north of the currently defined deposit along a projected north-south splay of the vein system. Results indicate the splay is mineralized in the first fence of holes (best hit NB15-272 – 1.5m @ 1.1 g/t gold and 75 g/t silver). However the grade drops off in the last fence to the north. Results suggest the northern extension of the YellowJacket system could be displaced to the west towards Northwest Sierra Blanca, which is planned for testing in the next phase of exploration drilling this spring.
Corvus Gold CEO, Jeffrey Pontius, stated:
These initial results with new areas of significant gold mineralization around our existing deposit are very encouraging for the expansion of the deposit. As we have seen from earlier results the potential of our currently defined resource appears to be unconstrained. In particular the new higher grade Savage Valley zone and its relationship to a hotter and potentially much larger system at depth are very intriguing and bode well for the district as a whole. As we have continued to see with the 2015 exploration program the North Bullfrog District is a large Nevadagold system that we believe has tremendous potential.
