Corvus Gold Expands New Rhyolite Vein Zone Discovery

Corvus Gold Inc. (TSX:KOR, OTCQX:CORVF) announced a new broad intercept from the Rhyolite Zone discovery northeast of the YellowJacket deposit on its North Bullfrog project in Nevada.
As quoted in the press release:

The new high-grade intercept of 10.7m of 3.47 g/t Au and 3.6 g/t Ag is within a broad interval of moderate grade mineralization (210m of 0.47 g/t Au and 1.4 g/t Ag) and represents a new center of gold-silver mineralization immediately east of the YellowJacket deposit.

The Rhyolite Zone mineralization is localized along a major NE trending structure which appears to be related to the large NE structures along the west side of the Sierra Blanca deposit to the southwest where earlier 2015 drilling intercepted higher level stockwork type mineralization (NB-15-425 with 4.1m @ 1.3 g/t Au and hole NB-15-426 with 3.7m @ 1.3 g/t Au).  Follow-up drilling to extend the Rhyolite Zone to the east is planned for later this month.

The Rhyolite Zone is centered on a NE-trending, moderate to steeply SE-dipping quartz vein/stockwork zone, hosted in a rhyolite intrusive body. The zone was intersected in 2014 by oriented core holes NB-14-352 and 392 at approximately the same elevation, and about 25 meters apart which confirmed NE-strike.  New hole NB-15-267 tested this zone about 25 meters vertically below, confirming the dip angle and grade continuity.
The zone is open along strike to the NE, SW and down-dip. With the confirmation of the Rhyolite Zone’s strike, dip and grade continuity, a new high-grade gold system is emerging marginal to the existing YellowJacket deposit.  It is important to note is that this is the first time Corvus Gold has specifically targeted a NE vein zone in the YellowJacket area and the fact that it is now surrounded by a very broad lower grade zone suggests the system is becoming stronger along strike and down dip.  This success has increased the potential for the other major NE structural zones that cross the YellowJacket deposit and extend to the east.

Corvus Gold CEO, Jeffrey Pontius, stated:

The results returned from the Rhyolite area have significantly increased the potential of the greater YellowJacket system.  The development of a new, broad multi-gram vein system to the east of the existing deposit holds good potential for proximal mill resource expansion.  Additionally the very broad zone of surrounding lower grade mineralization is important as it could be signalling a new center of mineralization in an area that has yet to be drill tested and highlights the upside potential and underexplored nature of this new District scale Nevada gold discovery.
