Corvus Gold Hits 15.2 metres of 2.36 g/t Gold in First 400m Step Out and Doubles Size of Property at North Bullfrog Project, Nevada
Corvus Gold announces the first results from its 2012 exploration drilling program on the North Bullfrog Project near Beatty, Nevada. Hole NB-12-117 encountered 52 metres of 0.8 g/t gold including a higher grade intercept of 15.3 metres of 2.36 g/t gold starting at 11 metres below the surface. Hole 117 was drilled at the Air Track West target, 400 metres west of the current boundary of the Sierra Blanca resource. The hole encountered gold mineralization within the favourable Crater Flat Tuff unit which is highly brecciated and maybe related to the deposit at Sierra Blanca. This hole confirms historical drilling in this exciting resource expansion target area (Figure 1). Results from the 2012 exploration drill program will not be included in the upcoming preliminary economic assessment (PEA) of the North Bullfrog Project anticipated to be completed later this month.
The RC drilling phase of the winter 2012 drilling program has now been completed, with a total of 1,700 metres drilled in 9 holes, and the Company has moved into the diamond drilling phase. The main focus of the RC program was to assess the overall resource footprint size to better target a +30,000 metres – 300 hole, Phase 2 RC drilling program which is currently being permitted and is scheduled to begin later this year. The north and west margins of the Sierra Blanca deposit were tested with approximately 400 metre step out holes to the west and the southern limit with 150 metre step outs that encountered gold mineralization. At the Jolly Jane deposit the northern extension has been tested with 200 and 400 metre step outs with results pending. The Phase 2 RC drill program will be designed to try and expand the existing oxide resource by assessing the possibility of the resource being connected throughout the overall project, as well as to increase the confidence of a large portion of the existing resource so that it can be upgraded to the measured and indicated categories.
The phase one diamond drilling program began on the 2nd of February with the primary objective of testing higher grade feeder structures in the Yellowjacket target area in the Northeastern portion of the project which has returned 11.9 g/t gold over 6.1 metres (NR11-03, February 1, 2011). Oriented core is being drilled to better understand the trend of this important high-grade target. In addition, large diameter core will be drilled in the key deposits so additional metallurgical testing can be conducted for use in a project development decision planned for later this year.
Corvus has added approximately 25 km² to its North Bullfrog Project by staking 312 federal mining claims, thereby bringing the land package to approximately 50 km². The new staking covers potential extensions of the North Bullfrog gold system as well as land that may be needed for any potential future mining operation.
Jeff Pontius, Corvus’ CEO, stated: “The intersection of shallow higher grade mineralization in a major step out, as seen in hole NB-12-117, is a significant positive for the North Bullfrog Project. If the other step out holes also return positive results, the potential impact on the resource base could be dramatic and take an already attractive project much farther down the road towards a potential development decision. Additionally, the start of the high-grade Feeder Zone exploration program is very exciting and, if successful, could fundamentally change the North Bullfrog Project and Corvus itself. Finally, the encouragement the North Bullfrog Project has generated over the past 12 months has led us to substantially expand our property position as it appears we may be on top of a major new Nevada gold discovery in an area with excellent infrastructure and a highly skilled workforce”.
About the North Bullfrog Project, Nevada
Corvus controls 100% of its North Bullfrog Project, which covers approximately 50 square kilometres in southern Nevada just north of the historic Bullfrog gold mine formerly operated by Barrick Gold. The property package is made up of a number of leased patented federal mining claims and 461 federal unpatented mining claims. The project has excellent infrastructure, being adjacent to a major highway and power corridor. The Company and its independent consultants are in the process of completing a PEA on the existing 43-101 resource which will be completed by the end of February, 2012.
The North Bullfrog Project currently includes numerous prospective gold targets with four (Mayflower, Sierra Blanca, Jolly Jane and Connection) containing an NI 43-101 compliant 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.

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.
