KOR-T Corvus Gold Discovers New Extension of YellowJacket Deposit at Swale Target and Expands NW Sierra Blanca Target, North Bullfrog Project, Nevada
VANCOUVER, June 7, 2016 /CNW/ - Corvus Gold Inc. ("Corvus" or the "Company") - (TSX: KOR, OTCQX: CORVF) announces 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 (Figure 1).
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 (Figure 2).
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).
Jeff Pontius, President and CEO of Corvus Gold Inc. said "We believe these initial positive results from follow-up drilling at NW Sierra Blanca and our new discovery at Swale are encouraging. NW Sierra Blanca's proximity to the current pit design continues to add potential for both mill and heap leach resources. This new discovery at Swale linked with our ongoing drilling of other new targets such as Lower Savage, Black Vein and Cloud 9 provides support for continuing the 2016 exploration program."

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 silverwithin 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.
About the North Bullfrog Project, Nevada
Corvus controls 100% of its North Bullfrog Project, which covers approximately 72 km² in southern Nevada. The property package is made up of a number of private mineral leases of patented federal mining claims and 865 federal unpatented mining claims. The project has excellent infrastructure, being adjacent to a major highway and power corridor as well as a large water right.
The North Bullfrog project includes numerous prospective gold targets at various stages of exploration with four having NI 43-101 mineral resources (Sierra Blanca, Jolly Jane, Mayflower and YellowJacket). The project contains a measured mineral resource of 3.86 Mt at an average grade of 2.55 g/t gold and 19.70 g/t silver, containing 316.5k ounces of gold and 2,445k ounces of silver, an indicated mineral resource of 1.81 Mt at an average grade of 1.53 g/t gold, and 10.20 g/t silver, containing 89.1k ounces of gold and 593.6k ounces of silver and an inferred resource of 1.48 Mt at an average grade of 0.83 g/t gold and 4.26 g/t silver, containing 39.5k ounces of gold and 202.7k ounces of silver for oxide mill processing. The mineral resource for the mill process was defined by WhittleTM optimization using all cost and recovery data and a breakeven cut-off grade of 0.52 g/t gold. In addition, the project contains a measured mineral resource of 0.3 Mt at an average grade of 0.25 g/t gold and 2.76 g/t silver, containing 2.4k ounces of gold and 26.6k ounces of silver, an indicated mineral resource of 22.86 Mt at an average grade of 0.30 g/t gold and 0.43 g/t silver, containing 220.5k ounces of gold and 316.1k ounces of silver and an inferred mineral resource of 176.3 Mt at an average grade of 0.19 g/t gold and 0.67 g/t silver, containing 1,077.4k ounces of gold and 3,799.2k ounces of silver for oxide, heap leach processing. The mineral resource for heap leach processing was defined by WhittleTM optimization using all cost and recovery data and a breakeven cut-off grade of 0.15 g/t.

The work program at North Bullfrog was designed and supervised by Mark Reischman, Corvus Gold's Nevada Exploration Manager, who is responsible for all aspects of the work, including the quality control/quality assurance program. On-site personnel at the project log and track all samples prior to sealing and shipping. Quality control is monitored by the insertion of blind certified standard reference materials and blanks into each sample shipment. All resource sample shipments are sealed and shipped to ALS Chemex inReno, Nevada, for preparation and then on to ALS Chemex in Reno, Nevada, or Vancouver, B.C., for assaying. ALS Chemex's quality system complies with the requirements for the International Standards ISO 9001:2000 and ISO 17025:1999. Analytical accuracy and precision are monitored by the analysis of reagent blanks, reference material and replicate samples. Finally, representative blind duplicate samples are forwarded to ALS Chemex and an ISO compliant third party laboratory for additional quality control.
