Corvus Gold Drills 17.9 g/t Gold and 260 g/t Silver over 9.2 metres Near Surface & Identifies New High-Grade Gold-Silver Vein Parallel to Yellowjacket Deposit, North Bullfrog Project, Nevada
March 3, 2014
Vancouver, B.C… Corvus Gold Inc. (“Corvus” or the “Company”) - (TSX: KOR, OTCQX: CORVF) announces the first drill results from its 2014 exploration program at the North Bullfrog Project, Nevada. Drill hole NB-14-378 intersected a newly identified vein system with massive quartz veining enriched in native gold and silver sulphide and located 50 metres to the west of the high-grade gold-silver Yellowjacket Deposit.
Results from a near surface 9.2 metre section of the main vein that were priority assayed yielded an intercept of 17.9 g/t gold and 260 g/t silver (Table 1, Figures 1 & 2). Assays for the remainder of the hole, which includes surrounding stockwork veining similar to the Yellowjacket Deposit to the east, are pending. This represents an important addition to the vein system at Yellowjacket and illustrates the new discovery potential for additional high-grade veins even in the immediate Yellowjacket Deposit area.

Jeff Pontius, Corvus CEO, stated “This new discovery of additional Yellowjacket type, shallow, high-grade, oxide, gold and silver veins continues to reinforce the scale and magnitude of this new Nevada high-grade discovery. The new West Vein offers potential to expand the existing high-grade resource of our already compelling Yellowjacket Deposit. With good initial cyanide recoveries from preliminary metallurgical work and an aggressive program to further optimize recovery and mining plans, we are excited about the impact that an expanded high-grade resource would have on our project. The first phase of our 2014 exploration program is focused on outlining large, potentially high-grade, resource expansion areas adjacent to the Yellowjacket Deposit, and will be followed up with a resource conversion drill program that will target a new resource update later this year. This new information, linked with our district wide exploration work, has identified a number of other Yellowjacket type targets which will be tested later this spring and punctuates the significant potential to outline a new, high-grade Nevada gold deposit.”

Yellowjacket – West Vein
Geological evaluation of the results from the Yellowjacket area after the close of the 2013 drill program indicated that the fault displacement mapped along the central part of the Josh Vein structure was not enough to account for the full stratigraphic offset indicated by other drilling to the west. On this basis, it was postulated that another strand of the fault should exist west of the known Josh Vein structure. Hole NB-14-377 (assays pending) confirmed the existence of the missing structure and hole NB-14-378 encountered a massive vein on the structure while hole NB-14-379 (assays pending) encountered the typical upper stockwork veining along the structure (Figures 1 & 2). The mineralization is rich in both gold and silver with abundant silver sulphide and resembles the discovery hole NB-12-138 (72.4m @ 1.74 g/t Au & 98.7 g/t Ag including the main vein interval of 4.3m @ 20.0 g/t gold & 1,519 g/t silver).
The fact that the vein transitions into near surface stockwork veining in NB-14-379 is a part of a pattern that has now been recognized along the full strike length of the vein explored to date. It is clear that the present topographic surface is just above the top of the high-grade veins. This realization means that the vein system remains open at depth and to the south of NB-12-138 where the structure has only been tested at shallow depths. Once the new West Vein strand has been explored, the Company plans to move the drill first to the north to define the northern strike extent of the Yellowjacket system and then again to continue exploration to the south and at depth.
About the North Bullfrog Project, Nevada
Corvus controls 100% of its North Bullfrog Project, which covers approximately 68 km2 in southern Nevada just north of the historic Bullfrog gold mine formerly operated by Barrick Gold Corp. 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.
The project currently includes numerous prospective gold targets, with the newly discovered Yellowjacket vein related deposit being the highest grade with an indicated resource at a 0.3 g/t gold cut-off of 4 Mt at an average grade of 0.97 g/t gold and 5.15 g/t silver for 125,000 ounces of gold and 662,000 ounces of silver and an inferred resource of 35.6 Mt with an average grade of 0.7 g/t gold and 3.86 g/t silver for 800,000 ounces of gold and 4.4M ounces of silver. At a cutoff grade of 1 g/t gold the Yellowjacket deposit contains an indicated resource of 0.9 Mt at 2.8 g/t gold and 16.5 g/t silver for 79,000 ounces of gold and 468,000 ounces of silver and an inferred resource of 4.5 Mt of 2.44 g/t gold and 17.5 g/t silver for 355,000 ounces of gold and 2.5M ounces of silver.
In addition to the Yellowjacket deposit, the property has a large low-grade oxide resource contained in five at surface deposits (Sierra Blanca, Air Track West, Jolly Jane, Mayflower and Connection) containing an estimated Oxidized Indicated Resource of 36.7 Mt at an average grade of 0.26 g/t gold for 307,860 ounces of gold and an Oxidized Inferred Resource of 242 Mt at 0.18 g/t gold for 1,366,000 ounces of gold (both at a 0.1 g/t gold cutoff), with appreciable silver credits. Unoxidized Inferred mineral resources are 213 Mt at 0.16 g/t for 1,117,000 ounces of gold (at a 0.1 g/t gold cutoff).

Cautionary Note Regarding Forward-Looking Statements
This press release contains forward-looking statements and forward-looking information (collectively, “forward-looking statements”) within the meaning of applicable Canadian and US securities legislation. All statements, other than statements of historical fact, included herein including, without limitation, statements regarding the anticipated content, commencement and cost of exploration programs, anticipated exploration program results, the discovery and delineation of mineral deposits/resources/reserves, the potential to expand the Yellowjacket deposit to the north, south and at depth, the potential for there to be additional veins outboard of the main Yellowjacket vein system and for any such veins to be high-grade, the potential to develop multiple Yellowjacket style high-grade zones, the potential for the North Bullfrog project to grow into a new Nevada high-grade gold discovery, the potential for any mining at or mineral production from North Bullfrog, the potential for the identification of multiple deposits at North Bullfrog, the potential for the Company to secure or receive any royalties in the future, business and financing plans and business trends, are forward-looking statements. Information concerning mineral resource estimates may also be deemed to be forward-looking statements in that it reflects a prediction of the mineralization that would be encountered, and the results of mining it, if a mineral deposit were developed and mined. Although the Company believes that such statements are reasonable, it can give no assurance that such expectations will prove to be correct. Forward-looking statements are typically identified by words such as: believe, expect, anticipate, intend, estimate, postulate, potential and similar expressions, or are those, which, by their nature, refer to future events. The Company cautions investors that any forward-looking statements by the Company are not guarantees of future results or performance, and that actual results may differ materially from those in forward looking statements as a result of various factors, including, but not limited to, variations in the nature, quality and quantity of any mineral deposits that may be located, variations in the market price of any mineral products the Company may produce or plan to produce, the Company's inability to obtain any necessary permits, consents or authorizations required for its activities, the Company's inability to produce minerals from its properties successfully or profitably, to continue its projected growth, to raise the necessary capital or to be fully able to implement its business strategies, and other risks and uncertainties disclosed in the Company’s 2013 Annual Information Form and latest interim Management Discussion and Analysis filed with certain securities commissions in Canada. All of the Company’s Canadian public disclosure filings may be accessed via www.sedar.com and readers are urged to review these materials, including the technical reports filed with respect to the Company’s mineral properties.
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 shareholders 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.
Caution Regarding Adjacent or Similar Mineral Properties
This news release contains information with respect to adjacent or similar mineral properties in respect of which the Company has no interest or rights to explore or mine. The Company advises US investors that the mining guidelines of the US Securities and Exchange Commission (the “SEC”) set forth in the SEC’s Industry Guide 7 (“SEC Industry Guide 7”) strictly prohibit information of this type in documents filed with the SEC. Readers are cautioned that the Company has no interest in or right to acquire any interest in any such properties, and that mineral deposits on adjacent or similar properties, and any production therefrom or economics with respect thereto, are not indicative of mineral deposits on the Company’s properties or the potential production from, or cost or economics of, any future mining of any of the Company’s mineral properties.
This press release is not, and is not to be construed in any way as, an offer to buy or sell securities in the United States.
