Corvus Gold Drills Continues to Expand the Limits of Vein/Stockwork System in the Yellowjacket Deposit, North Bullfrog Project, Nevada
November 20, 2014
New Upper Stockwork Zone: 1.7 metres @ 145 g/t Gold and 22 g/t Silver
Josh Vein + Stockwork: 8 metres @ 3.8 g/t Gold and 14 g/t Silver
Josh Vein + Stockwork: 18 metres @ 2.3 g/t Gold and 25 g/t Silver
Vancouver, B.C. Corvus Gold Inc. (“Corvus” or the “Company”) - (TSX: KOR, OTCQX: CORVF) announces results from holes NB-14-403 through NB-14-406 which continue the down-dip exploration of the main Josh Vein system of the Yellowjacket Deposit (Figure 1). Hole NB-14-403, returned 1.7 metres @ 145 g/t gold in a new stockwork zone above the Josh Vein system, testing the new zone approximately 175 metres down-dip from the surface (Figure 2) and 50 metres down dip from hole NB-14-377 (17m @ 2 g/t gold and 8.2 g/t silver, April 3, 2014 news release). This new zone marginal to the main Josh vein/stockwork system is another example of high-grade splay veins that are regularly being encountered as the system is being infill drilled.
Hole NB-14-405, which returned 18 metres of 2.3 g/t gold and 25 g/t silver, tested the structure at the same elevation as holes 403 and 406 but 250 metres to the north (Figure 1 & 2). In addition hole NB-14-405 tested the NE30 Fault Zone which occurs in the hangingwall of the Josh Vein and it returned a substantial intercept of 8.7 metres of 2.4 g/t gold and 12 g/t silver opening up a new vein system target for follow-up in 2015.
NB-14-406, which encountered 9.7 metres of solid vein material with 1.8g/t gold and 5g/t silver, tested the structure at the same elevation as NB-14-403 but 50 metres to the south. Hole NB-14-404, with 7.9 metres of 3.8 g/t gold and 14 g/t silver infills the same zone in between holes NB-14-377 and NB-14-378 (9.2m @18 g/t gold and 260 g/t silver, April 3, 2014 news release).
These results show that at 175 metres down-dip the vein/stockwork shoots are still well developed in both the north (NB-14-405) and south (NB-14-406) opening up future expansion potential. Future holes will continue to test the down-dip extensions and a series of holes are currently in progress to continue to test this elevation in the vicinity of discovery hole NB-12-138 (72m @ 1.7 g/t gold and 99 g/t silver including 4.3m @ 20 g/t gold and 1,519 g/t silver, January 22, 2013 news release) and farther south (Figure 1).
Jeff Pontius, CEO of Corvus Gold Inc. states “The overall continuity of the Josh Vein structure both along strike and down dip is remarkable and bodes well for further expansion. In addition the continued discovery of high grade splay veins like the one found in NB-14-403 with ongoing drilling of the margin and strike extent of the system is very encouraging for the possible discovery of other Josh Vein type systems within the overall Yellowjacket structural zone. The continued success of the Yellowjacket exploration program will likely make a significant impact on the deposit's size and quality and should have a positive impact on overall shareholder value in the coming year.”

(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 0.3 g/t gold equivalent has been used assuming a 59:1 price ratio of gold to silver.

Corvus Gold is currently utilizing two core drills focusing on expanding the Yellowjacket resource along strike, internally and at depth. Phase II drilling will include approximately 30 core holes with only 8 reported to date designed to expand the Yellowjacket deposit, define bonanza grade ore shoot within the deposit and provide material for continuing advanced metallurgical testing. The Phase II program will continue through November and following the return of all results the Company plans on calculating a new resource estimate in the first quarter of 2015. The new resource estimate 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 very 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 permitting.
About the North Bullfrog Project, Nevada
Corvus controls 100% of its North Bullfrog Project, which covers approximately 68 km² in southern Nevada. The property package is made up of a number of private mineral leases of patented federal mining claims and 758 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.
