Vancouver, B.C. - Corvus Gold Inc. (“Corvus” or the “Company”) - (TSX: KOR, OTCQX: CORVF) announces results from holes NB-14-400 and NB-14-401 which have respectively returned broad intercepts of 36 metres @ 17 g/t gold and 32 metres of 5 g/t gold (Table 1).Â These new results continue to fill a gap in the previous drilling in an area targeted for high-grade mineralization related to shoot development (Figure 1). Â This release represents the first three of 18 completed holes with another 10-12 planned holes in the phase two 2014 drill program.
Mineralization in this target area occurs in the form of native gold in quartz veins primarily within the stockwork zone around the main Josh Vein. Â This new high-grade zone, originally hit in hole NB-14-399, is expanding at depth with grades that are 5 to 15 times the average of the system overall and higher than the main Josh Vein. Â These results indicate that the most productive part of the system is not exclusively the main Josh Vein and opens up the possibility of further broad above Josh Vein grade zones within Yellowjacket’s stockwork.

(Reported drill intercepts are not true widths.Â 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.
Jeff Pontius, CEO of Corvus, stated “These new results from what appears to be a key shoot in the Yellowjacket vein system have significantly expanded the potential of the deposit.Â Hole NB-14-400 is the best high-grade broad intercept drilled to date on the North Bullfrog Project and has now clearly outlined our large Gap Area “Shoot Target”. Â With only 3 of 18 completed holes reported in the ongoing Phase 2 drill program, the initial results are encouraging and continue to showcase the expansion potential as we unlock the high-grade shoot zones of the Yellowjacket Deposit.”

Geology of Holes NB-14-400 and NB-14-401
Holes NB-14-400 and NB-14-401 confirm the down dip continuity of the Josh vein system and suggest that the interaction of two faults may be responsible for the broad zones of stockwork and bonanza grades found in these holes (Figure 2). Â The consistency of the mineralization in NB-14-400 is remarkable, with 40% of the samples having more than 10 g/t gold (Table 2). Â Within the stockwork, native gold occurs in millimeter wide veinlets where they interact with pre-existing veins forming spectacular dendritic textures (Figure 3). Â The style of mineralization is similar to that observed in hole NB-13-347 (14m @ 7 g/t gold and 21 g/t silver, NR13-20, September 5, 2013) and NB-14-399 (9.4 m @ 2.5g/t gold and 14g/t silver; NR14-18, October 1, 2014) which are approximately 50 metres up plunge from NB-14-400. Â Work is currently underway to determine the specific controls on this bonanza grade mineralization.Â The gap target zone is currently about 200 metres long and has been tested to a depth of about 175 metres down dip.
Corvus is currently utilizing two core drills focusing on expanding the Yellowjacket resource along strike, internally and at depth. Â Phase II drilling will include approximately 30 core holes designed to expand the Yellowjacket deposit, define bonanza grade shoots within the deposit and provide material for continuing advanced metallurgical testing.Â The Phase II program will continue through November and, following the return of all results, the Company plans on calculating a new estimated resource in the first quarter of 2015.Â This resource will form the basis of an initial Preliminary Economic Assessment (PEA) that will incorporate the Yellowjacket discovery.Â The PEA is scheduled to be completed in Q2 of 2015.Â In addition, Corvus is engaged in detailed metallurgical studies of the new high-grade mineralization which have provided very encouraging initial results.Â The North Bullfrog Project is also being advanced on a number of development fronts as well as project characterization work ahead of permitting.

Â Traces are coloured by gold grade with red meaning 1-4g/t gold and fuchsia indicating greater than 4g/t gold. Â This is the first time the Josh Footwall Fault has been identified but it appears to be an important control on mineralization.

About the North Bullfrog Project, Nevada
Corvus controls 100% of its North Bullfrog Project, which covers approximately 68 kmÂ≤ in southern Nevada.Â The property package is made up of a number of private mineral leases of patented federal mining claims and 758 federal unpatented mining claims.Â 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.Â 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.Â 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”).Â Accordingly, the Company’s disclosures regarding mineralization may not be comparable to similar information disclosed by companies subject to SEC Industry Guide 7.Â 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.Â 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.Â Further, inferred resources have a great amount of uncertainty as to their existence and as to whether they can be mined legally or economically.Â It cannot be assumed that all or any part of the inferred resources will ever be upgraded to a higher resource category.Â Under Canadian rules, estimates of inferred mineral resources may not form the basis of a feasibility study or prefeasibility study, except in rare cases.Â 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.Â The term “contained ounces” is not permitted under the rules of SEC Industry Guide 7.Â In addition, the NI 43-101 and CIM Standards definition of a “reserve” differs from the definition in SEC Industry Guide 7.Â 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.
