Corvus Gold Extends Main Josh Vein of the Yellowjacket Deposit at North Bullfrog Project, Nevada
TSX: KOR OTCQX: CORVF
VANCOUVER, April 3, 2014 /PRNewswire/ - Corvus Gold Inc. ("Corvus" or the "Company") - (TSX: KOR, OTCQX: CORVF) announces new results from the 2014 Phase One drill campaign at the North Bullfrog Project in Nevada. Assay results include the full intercept of the previously reported hole NB-14-378 as well as two recently drilled holes (Table 1). Hole NB-14-377, in the Yellowjacket deposit, intersected the Josh Vein 150 metres down dip from the surface a returning 17 metres @ 2 g/t gold and 8 g/t silver establishing the down dip continuity (Figure 1). In addition, hole NB-14-379 tested the top of the new West Vein zone 20 meters below the surface, and returned typical high level mineralization with a 1.1 metre wide vein @ 2.4 g/t gold and 7.8 g/t silver within a broader zone of low-grade mineralization.
Full assay results have now been received from hole NB-14-378 (initially reported in NR-14-08, March 3, 2014) which intersects the West Vein about 65 metres down dip from hole NB-14-379. The hole returned a vein intersection of 9.2 metres @ 18 g/t gold and 260 g/t silver, thereby establishing the elevation control on the top of the high grade veins in the greater Yellowjacket - West Vein area (Figure 2). This same elevation control may be reflected in hole NB-14-380 (initially reported in NR-14-09, March 13, 2014) with an upper zone, at 50 metres down-hole depth, of 3.6 metres of 4.19 g/t gold and 150 g/t silver and a lower zone, about 40 metres down-hole deeper, of 4.8 metres @ 13.8 g/t gold and 243 g/t silver. The assays from the remainder of this hole, which include the areas between and surrounding the veins, are pending. As the Phase One program continues, drilling is intended to outline the expansion potential of the new West Vein discovery and conduct initial testing of the northern and southern extension potential, as well as test the depth extent, of the Yellowjacket deposit.
An additional five holes have now been completed in the West Vein target area and visible gold and silver (acanthite) associated with quartz veining has been observed in a number of intervals. The most productive zone for thick quartz vein development in the West Vein target currently appears to start below 40 metres down-hole in depth and has only been tested to 100 metres down-hole depth at this time (Figure 2). Continuity of this new vein system has now been established for over 100 metres in strike length and remains open (Figure 1). The Company believes that the West Vein will ultimately intersect the Main Josh Vein towards the North and South at different depths.
Jeff Pontius, Corvus CEO, stated "The extension of the main Josh Vein to the south and the development of a large new high-grade quartz vein system in the West Vein target bode well for the potential expansion of the Yellowjacket high-grade resource. As we drill these priority high-grade targets we continue to find new and exciting potential for an expanding system. Of particular interest is following the Yellowjacket system at depth and exploring for other parallel systems to the west like the new West Vein discovery. The robust nature of the current estimated resource in a low gold price environment and its leverage to higher prices has defined North Bullfrog as a significant new Nevada gold discovery with attractive exploration potential."

Yellowjacket Vein Zone Exploration
The Yellowjacket Vein Zone at North Bullfrog is currently defined by the Josh Vein on the west and the Liberator Fault on the east (Figure 1). The interaction of these two faults has created a large broken zone which contains major veins, such as the Josh Vein, and broad zones of stockwork mineralization. The West Vein strand delineated by 2014 drilling represents a new hangingwall splay off the main Josh Vein Fault and also carries substantial high-grade gold and silver mineralization with similar resource potential as it extends to the south.
Drilling now indicates that large northeast faults such as the NE30 and NE50 faults (Figure 1) do not cut off the Josh Vein Fault system but enhance it as a host for high-grade gold and silver veins. This new information indicates that there is significant potential for mineralization along the northeast structures themselves as they go across the main low-grade deposit to the west. In addition the wedge-shaped zone between the Josh Vein and the Liberator Fault has proven to have many more mineralized structures than previously thought, thereby enhancing the overall potential for additional high-grade mineralization (Figure 2).
The 5,000 metre Phase One drilling program at North Bullfrog will continue to focus on delineating the limits of the Yellowjacket system. In the planned 15,000 metre Phase Two program, additional core rigs will be added to conduct resource definition drilling and continue with the District-wide exploration for other high-grade vein systems.
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 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 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 develop multiple Yellowjacket style high-grade zones, the Company's belief that the the West Vein will ultimately intersect the Main Josh Vein towards the North and South at different depths, the Company's belief for there to be significant potential for mineralization along the northeast structures themselves as they go across the main low-grade deposit to the west; the potential to discover additional high grade veins or additional deposits, the potential to expand the existing estimated resource at the North Bullfrog project, the potential for any mining or production 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 be deemed to be forward-looking statements in that it reflects a prediction of the mineralization that would be encountered 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 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.
