Corvus Gold Hits 5.4m of 16.2 g/t Gold and 1,218 g/t Silver in Yellow Jacket Feeder Zone, North Bullfrog Project, Nevada
VANCOUVER, BRITISH COLUMBIA -- (Marketwire) -- 05/23/12 -- Corvus Gold Inc. ("Corvus" or the "Company") - (TSX: KOR)(OTCQX: CORVF) is pleased to announce the latest results from diamond drilling in the Yellow Jacket Zone at the Company's 100%, North Bullfrog Project near Beatty, Nevada. Hole NB-12-138, which is outside the current in-pit resource as reported in the Preliminary Economic Assessment (NR 12-07, Feb.28, 2012) is the fifth core hole to be drilled in the Yellow Jacket Zone that encountered high-grade gold mineralization (Table 1). This latest intersection returned three separate high-grade intervals with the best being 16.2 g/t (0.47 ozs/t) gold and 1,218 g/t (35.5 ozs/t) silver over 5.4 metres including 2.1 metres of 33.0 g/t (0.96 ozs/t) gold and 2,870 g/t (83.7 ozs/t) silver within quartz veined hydrothermal breccia. These high-grade intervals have elevated selenium and tellurium values similar to those reported in the silver-rich gold mineralization found at the historic Bullfrog Mine approximately 10 km's to the south of North Bullfrog. High selenium values are an important characteristic at the Ken Snyder deposit in northern Nevada. The results continue to confirm the continuity of the structurally controlled, high-grade gold mineralization previously reported from this area (NR12-10, Mar. 22, 2012) and open up an attractive new high-grade gold and silver target at depth.
Jeff Pontius, Corvus Gold CEO states: "The high-grade gold and silver mineralization encountered in NB-12-138 continues to confirm our covered, feeder zone target concept, opening up significant potential for expanding this very attractive zone of mineralization. This style of high-grade mineralization has produced exceptional deposits throughout Nevada and we are excited about further defining its potential on the North Bullfrog project."

Yellow Jacket High-Grade System Analysis
The Yellow Jacket target is in the northern part of the district currently outside existing pit perimeters (To view Figure 1, please visit the following link: http://media3.marketwire.com/docs/cor523i.pdf). Five diamond drill holes along the Yellow Jacket structural corridor have intersected an extensive structural zone with multiple styles of gold mineralization including both quartz veining and pyrite replacement of iron-rich lithologies. The style of quartz veining found in NB-12-138, which includes colloform and crustiform quartz, is different from that found in the other holes and represents a more dynamic and productive part of the Yellow Jacket feeder zone system. These new veins are associated with multistage hydrothermal breccias with the highest grades associated with visible gold and acanthite, a high-grade silver mineral. Prior to this intersection, most of the observed quartz veining hosting high-grade gold has been relatively uniform textured milky grey quartz with pyrite which may have been distal to the more dynamic hydrothermal zone intercepted in hole NB-12-138. This current high-grade zone displays evidence of very active boiling at depth and bodes well for discovery of more elevation controlled high-grade mineralization at depth along this broad, +2 kilometre long structural target.
The current North Bullfrog program drilling is focussing on infill drilling, advanced metallurgical work and environmental baseline characterization studies in conjunction with a completion of a feasibility study by early 2013 on the Mayflower deposit. The recently completed financing has now provided the Company with the financial resources needed to rapidly advance the mine development assessment of the North Bullfrog area as well as continued exploration of this major new high-grade Nevada gold discovery.
About the North Bullfrog Project, Nevada
Corvus controls 100% of its North Bullfrog Project, which covers approximately 43 km2 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 completed a robust positive Preliminary Economic Assessment on the existing resource in February 2012.
The 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.

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 for any mining or production at North Bullfrog, the potential for the identification of multiple deposits at North Bullfrog, the potential for a low-cost run-of-mine heap leach operation at North Bullfrog, the potential for there to be a low strip ratio in connection with any mine at North Bullfrog, the potential for the existence or location of additional high-grade veins, the proposed completion of a PEA for the North Bullfrog project, the potential for additional resources to be located between certain of the existing deposits, 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. 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 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 latest interim Management Discussion and Analysis and 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 are not indicative of mineral deposits on the Company's 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.
