Vancouver, B.C… Corvus Gold Inc. (“Corvus” or the “Company”) - (TSX: KOR, OTCQX: CORVF) announces further results from its 2014 exploration program to test the southern expansion potential of the Yellowjacket deposit. The results also include a series of holes that expand the previously discovered West Vein zone at depth which include NB-14-414 (11 metres @ 8.1 g/t gold and 30 g/t silver) and NB-14-410 (9.9 metres @ 3.2 g/t gold and 124.3 g/t silver) (Table 1, Figure 1). Holes NB-14-417 (7.8 metres @ 1.1 g/t gold and 1 g/t silver) and NB-14-422 (3.5 metres @ 2.6 g/t gold and 3.3 g/t silver) illustrate the continuation of Yellowjacket type vein mineralization well to the south of the 2013 resource area. Although drilling conditions to the south were difficult and several holes were lost due to poor ground these new results indicate that the Yellowjacket system now continues at least 200 metres to the south of the deposits original discovery hole NB-12-138 (4.3 metres @ 20 g/t gold and 1519 g/t silver) with broad oxide, heap leach mineralization extending at least another 100 metres beyond that. 

The current interpretation of the southern Yellowjacket expansion zone is the typical Josh type higher grade vein system is further at depth which will be an immediate target for future exploration.  In addition new high-grade vein targets are developing in this area such as the NE60 and NE70 fault zones, with characteristic upper level Josh Vein type mineralization like that in hole NB-14-424 (7.3 metres of quartz vein with 0.6 g/t gold and 4 g/t silver). The southern exploration program has now outlined a significant new Yellowjacket resource expansion area for future exploration.

Jeff Pontius, CEO of Corvus Gold Inc. said “The 2014 drill campaign has significantly expanded the size, grade and quality of the Yellowjacket resource.  The discovery of several new high-grade veins during the 2014 program and the currently unconstrained nature of the deposit suggest that Yellowjacket as well as other similar and untested zones in the North Bullfrog district have potential to develop into a large new Nevada, high-grade gold-silver District.  The knowledge gained in 2014 has formed the foundation for a new District wide exploration program in 2015 to determine the potential of this new multimillion ounce Nevada discovery.  In addition over the next few months the results from the 2014 work will be integrated into a new resource statement and our first PEA looking at the high-grade system and its impact on the overall project.”

Geological Results

The Josh Vein intercepts in holes NB-14-410 (2.2 metres of 8.9g/t gold and 450 g/t silver), NB-14-412 (4.5 metres of 1.0 g/t gold and 20 g/t silver, NB-14-414 (11 metres with 8.1 g/t gold and 30 g/t silver) and NB-14-416 (6.6 metres with 0.9 g/t gold and 17 g/t silver) tested the down-dip extensions of the West Vein to a depth of approximately 200 metres.

All of the holes in the southern exploration reported here have encountered significant intervals of disseminated oxide mineralization some of it with grades substantially higher than the average resource (Table 1). New drill roads on the top of Sierra Blanca have produced chip channel sampling (SBRC-15) which shows continuous mineralization with quartz vein stockwork zones carrying grades that are much higher than the average heap leach resource (Figure 1). This mineralization should substantially impact early mine production from the heap leach material.

High Grade Shoots within Josh Vein

The interaction between the Josh Vein and the NE50, NE60 and NE70 fault zones may (Figure 1) be an important control on the development of high-grade shoots within the Josh Vein system and defining the locations and character of these faults represents a big step forward for future targeting of high-grade zones like those defined in hole NB-14-400 (35.9 metres @ 17 g/t gold and 20 g/t silver).

A new target, NE60 that is now emerging as a potential new high-grade discovery was first intersected in early exploration in holes NB-07-02 (4.5 metres of 1.6 g/t gold and 1.1 g/t silver) and RDH-768 (1.5 metres of 1.2 g/t gold and 0.4 g/t silver). Hole NB-14-407 also encountered the mineralized NE60 fault (5.4 metres of 0.83 g/t gold and 2.5 g/t silver), as well as in holes NB-14-419, NB-14-423 and NB-14-420.  This new broad zone of structurally (fault zone) hosted gold is similar to the mineralization above the Josh Vein to the north and has developed a potential high-grade target at depth.

The NE70 fault zone target was a conceptual target from geologic modeling and was initially tested in 2014 returning very encouraging results in holes NB-14-417 (7.8 metres of 1.1 g/t gold and 1 g/t silver) and NB-14- 422 (32 metres of 0.61 g/t gold and 1.2 g/t silver).  As with the NE60 target these intercepts are from the upper parts of the system with the main high-grade zone projected to be deeper in the system.

(Reported drill intercepts are not true widths.  At this time, there is insufficient data with respect to the shape of the mineralization to calculate its true orientation in space.)

*The vein intervals are defined as having >50% quartz infill and stockwork is defined as the interval in the immediate hangingwall and footwall of the vein where overall vein density exceeds 5%. Within the stockwork  zones a cutoff of 0.3g/t gold equivalent has been used assuming a 59:1 price ratio of gold to silver. For disseminated oxide zones a cutoff of 0.1g/t gold has been applied.

Exploration Program

Final geological modeling of the Yellowjacket Zone is currently underway and it is anticipated that a new resource will be calculated in the first quarter of 2015.  This resource will form the basis of an initial Preliminary Economic Assessment (PEA) that will incorporate the Yellowjacket discovery   The PEA is scheduled to be completed in Q2 of 2015.  In addition, Corvus is engaged in detailed metallurgical studies of the new high-grade mineralization which have provided encouraging initial results.  The North Bullfrog project is also being advanced on a number of development fronts as well as project characterization work ahead of mine permitting.

About the North Bullfrog Project, Nevada

Corvus controls 100% of its North Bullfrog Project, which covers approximately 75 km² in southern Nevada.  The property package is made up of a number of private mineral leases of patented federal mining claims and 814 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.

Based upon a USD 1300 gold price and a silver to gold price ratio of 59:1, the North Bullfrog project currently has estimated mineral resources defined in six deposits: the structurally controlled Yellowjacket milling deposit and the oxidized disseminated heap leach Sierra Blanca, Jolly Jane, Air Track West, Connection and Mayflower deposits.  The Yellowjacket vein-style deposit has an Indicated Mineral Resource of 3.69 Mt at an average grade of 1.03 g/t gold and 5.52 g/t silver for 122,000 contained ounces of gold and 654,000 ounces of silver and an Inferred Mineral Resource of 18.40 Mt with an average grade of 0.94 g/t gold and 6.16 g/t silver for 555,000 contained ounces of gold and 3.64M ounces of silver, both at a 0.29 g/t gold cutoff.

The five oxidized disseminated heap leach deposits contain an Indicated Mineral Resource of 25.72 Mt at an average grade of 0.29 g/t gold for 240,000 contained ounces of gold and an Inferred Mineral Resource of 185.99 Mt at 0.19 g/t gold for 1,136,000 contained ounces of gold (both at a 0.13 g/t gold cut-off), with appreciable silver credits.

Cautionary Note Regarding References to Resources and Reserves

National Instrument 43 101 - Standards of Disclosure for Mineral Projects (“NI 43-101”) is a rule developed by the Canadian Securities Administrators which establishes standards for all public disclosure an issuer makes of scientific and technical information concerning mineral projects.  Unless otherwise indicated, all resource estimates contained in or incorporated by reference in this press release have been prepared in accordance with NI 43-101 and the guidelines set out in the Canadian Institute of Mining, Metallurgy and Petroleum (the “CIM”) Standards on Mineral Resource and Mineral Reserves, adopted by the CIM Council on November 14, 2004 (the “CIM Standards”) as they may be amended from time to time by the CIM.

United States investors are cautioned that the requirements and terminology of NI 43-101 and the CIM Standards differ significantly from the requirements and terminology of the SEC set forth in the SEC’s Industry Guide 7 (“SEC Industry Guide 7”).  Accordingly, the Company’s disclosures regarding mineralization may not be comparable to similar information disclosed by companies subject to SEC Industry Guide 7.  Without limiting the foregoing, while the terms “mineral resources”, “inferred mineral resources”, “indicated mineral resources” and “measured mineral resources” are recognized and required by NI 43-101 and the CIM Standards, they are not recognized by the SEC and are not permitted to be used in documents filed with the SEC by companies subject to SEC Industry Guide 7.  Mineral resources which are not mineral reserves do not have demonstrated economic viability, and US investors are cautioned not to assume that all or any part of a mineral resource will ever be converted into reserves.  Further, inferred resources have a great amount of uncertainty as to their existence and as to whether they can be mined legally or economically.  It cannot be assumed that all or any part of the inferred resources will ever be upgraded to a higher resource category.  Under Canadian rules, estimates of inferred mineral resources may not form the basis of a feasibility study or prefeasibility study, except in rare cases.  The SEC normally only permits issuers to report mineralization that does not constitute SEC Industry Guide 7 compliant “reserves” as in-place tonnage and grade without reference to unit amounts.  The term “contained ounces” is not permitted under the rules of SEC Industry Guide 7.  In addition, the NI 43-101 and CIM Standards definition of a “reserve” differs from the definition in SEC Industry Guide 7.  In SEC Industry Guide 7, a mineral reserve is defined as a part of a mineral deposit which could be economically and legally extracted or produced at the time the mineral reserve determination is made, and a “final” or “bankable” feasibility study is required to report reserves, the three-year historical price is used in any reserve or cash flow analysis of designated reserves and the primary environmental analysis or report must be filed with the appropriate governmental authority. U.S. investors are urged to consider closely the disclosure in our latest reports and registration statements filed with the SEC. You can review and obtain copies of these filings at http://www.sec.gov/edgar.shtml. U.S. Investors are cautioned not to assume that any defined resource will ever be converted into SEC Industry Guide 7 compliant reserves.
