Corvus Gold Inc. (TSX:KOR, OTCQX:CORVF) announced the initial drill results from the 2016 North Bullfrog exploration program. Results have demonstrated the continuity of gold mineralization directly adjacent to the current pit design at the NW Sierra Blanca target along with a significant new discovery at the Swale target immediately north of the YellowJacket/Sierra Blanca deposits.

As quoted in the press release:

The initial hole at the new Swale target (NB-16-300) intersected 18.3m of 1.76 g/t gold & 2.4 g/t silver (Table 1).  The new Swale discovery is characterized by extensive quartz stockwork mineralization that is directly associated with a large rhyolite intrusive.

Drilling at the NW Sierra Blanca target has extended gold mineralization to the northeast toward the current north end of the YellowJacket deposit, with alteration and grades increasing in this direction (NB-16-298 intersecting 22.9m of 1.69 g/t gold & 2.64 g/t silver).

New Swale Discovery

The discovery at the Swale target represents a new style of gold mineralization with both quartz vein and replacement type, which are uniquely hosted by an extensive rhyolite intrusive body that is located at the north end of the YellowJacket trend.  Results from two holes have been returned from the Swale target to date with hole NB-16-300 intersecting the new zone at the bottom of the hole (18.3m @ 1.76 g/t Au).  The Swale mineralization is directly associated with an intensely fractured and altered rhyolite body.  Hole NB-16-299 intersected the edge of this new zone at the bottom of the hole where alteration intensity was increasing, follow up drilling is ongoing.

This newly discovered mineralized zone appears to be associated with the intersections from two broad NW and NE structural zones at the north end of the current defined YellowJacket deposit.  This major intersection appears to of controlled the emplacement of the extensive rhyolite body and the associated gold mineralization.  The rhyolite intrusive body is highly fractured and forms a favourable host and may have a genetic association with the gold systems in the area.  Two additional holes drilled to the west of NB-16-300 (NB-16-304 & 305) intersected thick intervals of highly altered and quartz veined rhyolite which suggests the favourable host unit extends to the west (assays pending).  In addition the rhyolite body extends to the north and east of the YellowJacket deposit including the NE-trending, Rhyolite Vein discovered in 2015 (10.7m @ 3.5 g/t Au).

NW Sierra Blanca Target

A total of six holes from the 2016 exploration program have been returned from the NW Sierra Blanca target covering about 400 metres of the north end of the system.  These results continue to show good continuity of the new mineralized zone which lies just west of the current resource/pit boundary.  The current data has shown that grades are increasing to the northeast toward the north end of the YellowJacket Deposit with the farthest hole to the northeast, NB-16-298 returning 22.9 meters of 1.69 g/t gold and 2.6 g/t silver from a broad zone of stockwork quartz veining.  This new vein system discovery is about 100 metres west and trends parallel to the YellowJacket deposit.  When linked with prior intercepts like hole NB-15-282 which returned 3.1m @ 5 g/t gold and 42 g/t silver within 19.8m of 1.7 g/t Au and 12 g/t Ag the area has emerged as a significant new zone of high grade mineralization which could expand the current mill resource, follow up drilling is ongoing.
