Corvus Gold Extends Yellow Jacket High-Grade Gold and Silver System North by 260 Metres, North Bullfrog Project, Nevada
Vancouver, B.C… Corvus Gold Inc. (“Corvus” or the “Company”) – (TSX: KOR, OTCQX: CORVF) announces assay results from five additional core drill holes from the ongoing 2013 drill campaign at the Yellow Jacket target, North Bullfrog Project, Nevada (Figure 1). Characteristics of mineralization identified in drill holes NB-12-138, NB-13-344 & NB-13-347 indicate the potential of a high-grade starter pit zone that can be incorporated into the Sierra Blanca deposit (Figure 3). Upon conclusion of the current drill program, an updated resource calculation is scheduled for release late 2013 with an updated PEA anticipated early next year.
Drill hole NB-13-347, intersected 13.8 metres of 7.2 g/t gold and 21.0 g/t silver, including 1.7 metres averaging 8.5 g/t gold and 256 g/t silver. It represents a 260-metre step-out north of 2012 discovery hole NB-12-138 with a core of 4.3 metres @ 20.0 g/t gold & 1,519 g/t silver and 140 metres north of hole NB-13-344 with a core of 8.3 metres @ 10.7 g/t gold and 10.4 g/t silver (Table 1). Only 43 metres of assays have been returned from hole NB-13-347 with the remainder expected next month.
These thick high-grade cores zones are part of much broader zones of 50 to 80 metres averaging over a gram per tonne with high silver credits and form a very attractive open pit mining target. The high-grade feeders appear to be occurring on regular intervals like fingers on a hand along the north trending Yellow Jacket Zone and may represent the upper levels of a larger high-grade system at depth. The Yellow Jacket system has only been tested at relatively wide spacing in the top 150 metres and remains open along strike and at depth. These feeders are surrounded by lower grade stockwork and disseminated zones and can be fully exploited with open pit mining.
In addition, hole NB-13-343, which is on the same section as NB-12-344, and hole NB-13-346, which lies halfway between NB-13-344 and NB-13-347 returned thick moderate grade intercepts which reflecting the surrounding disseminated and stockwork style of mineralization and confirm the continuity within the overall broad structural zone.
Jeff Pontius, Chief Executive Officer, states: “These most recent results continue to build tonnes and confidence in our new high-grade Yellow Jacket zone. The exceptional grade of multiple high-grade feeders along the broad and extensive Yellow Jacket zone in the near surface strongly supports deeper drilling for a larger deposit as these types of systems often extend for +500 metres in depth. The Yellow Jacket and possibly other new discoveries in this part of the District offer great potential for a new and emerging high-grade gold-silver deposit similar to the historic + 2 million ounce Bullfrog Mine 8 kilometres to the south.”

About the North Bullfrog Project, Nevada
Corvus controls 100% of its North Bullfrog Project, which covers approximately 70 km² in southern Nevada just north of the historic Bullfrog gold mine formerly operated by Barrick Gold Corporation. The property package is made up of a number of leased patented federal mining claims and 758 federal unpatented mining claims. The project has excellent infrastructure, being adjacent to a major highway and power corridor. The Company’s independent consultants completed a robust positive Preliminary Economic Assessment on the existing resource in December 2012.
The project currently includes numerous prospective gold targets with four (Mayflower, Sierra Blanca, Jolly Jane and Connection) containing an estimated Indicated Resource of 15 Mt at an average grade of 0.37 g/t gold for 182,577 ounces of gold and an Inferred Resource of 156 Mt at 0.28 g/t gold for 1,410,096 ounces of gold (both at a 0.2 g/t cutoff), with appreciable silver credits. Mineralization occurs in two primary forms: (1) broad stratabound bulk-tonnage gold zones such as the Sierra Blanca and Jolly Jane systems; and (2) moderately thick zones of high-grade gold and silver mineralization hosted in structural feeder zones with breccias and quartz-sulphide vein stockworks such as the Mayflower and Yellowjacket targets. The Company is actively pursuing both types of mineralization.

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 in Reno, 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. McClelland Laboratories Inc. prepared composites from duplicated RC sample splits collected during drilling. Bulk samples were sealed on site and delivered to McClelland Laboratories Inc. by ALS Chemex or Corvus personnel. All metallurgical testing reported here was conducted or managed by McClelland Laboratories Inc.
