VANCOUVER, Jan. 22, 2013 /CNW/ - Corvus Gold Inc. ("Corvus" or the "Company") - (TSX: KOR, OTCQX: CORVF) announces the latest assays from the final drill holes of the Phase II, 2012 Yellow Jacket drill program at the North Bullfrog Project, Nevada. The four hole program has now extended and further delineated the trend of the bonanza grade feeder system identified earlier in 2012. Best result to date was NB-12-138 which returned 72.4 metres @ 1.74 g/t gold and 98.7 g/t silver including 4.3 metres @ 20.0 g/t gold and 1,519 g/t silver (Table 1).
The Yellow Jacket high-grade target area is located directly north of the currently delineated Sierra Blanca deposit. Results to date have not been incorporated in the current North Bullfrog estimated resource and updated preliminary economic assessment. Subsequent drilling is expected to add to the overall gold resource at North Bullfrog, and a global resource update, incorporating the Yellow Jacket target results, is planned for late 2013.
The most recent result, Hole NB-12-184, intersected 58 metres @ 1.7 g/t gold and 33 g/t silver including 3.8 metres @ 4.1 g/t gold and 151 g/t silver, 4.4 metres @ 6.9 g/t gold and 50.4 g/t silver and 4.1 metres @ 4.3 g/t gold and 25 g/t silver (Table 1).
The Yellow Jacket high-grade, fault controlled, gold and silver mineralization has been encountered over a strike length of approximately 700 metres and remains open on strike and at depth. 3D IP imaging has now linked the Yellow Jacket discovery to a large master fault system which extends for over 2 kilometres in length and could have significant potential for additional high-grade mineralization. In addition, recent detailed mapping, which utilized the new geophysical data, has now highlighted a number of other structural zones with similar signatures to the Yellow Jacket discovery and possible high-grade potential. Aggressive follow-up drilling of the Yellow Jacket system and several other targets is expected to commence early 2013.
The most recent program, which commenced in October 2012, hit significant vein mineralization with broad zones of gold and silver mineralization hosting within it bonanza grade ore shoots which remain open on strike and at depth (Table 1). All vein intersections to date are within 150 metres of the surface (representing potential open pit mining depths) with quartz veins widening at depth (Figure 2), and none of these have been included in the current North Area estimated resource. The silver to gold ratio of mineralization in these veins is distinctly higher than the overall North Bullfrog resource estimate and could represent a major new silver discovery in the district which could significantly benefit the overall project. The Yellow Jacket target area is emerging as a significant new high-grade zone adjacent to the North Area deposit which could have a major impact on mining economics as a starter pit zone within the overall deposit, operating at a much higher grade with significant silver credits.
Jeff Pontius, Corvus CEO, stated: "The near surface, high-grade Yellow Jacket zone not only offers an immediate positive impact on the North Area mine plan as a potential higher value starter phase, but also potential to evolve into a major new high-grade deposit in its own right. We believe the exploration potential for expanding the Yellow Jacket system and discovering new yet to be tested systems is high with our new understanding of the District. We at Corvus are very excited as we kick off our aggressive 2013 exploration and mine development program which will focus on expanding the high-grade and heap leach potential of the North Area as well as moving our Mayflower project through permitting and into planned development."
Evolution of the Yellow Jacket Vein System Discovery
The Yellow Jacket vein system represents a completely blind discovery of a large, previously unrecognized, high-grade gold and silver system in the North Bullfrog District (Figure 1). Prior drilling in this area was focussed to the east in an area of historic prospect pits along the Liberator and Yellow Jacket Faults, with RC hole NB-10-63 intersecting 10.7 metres @ 7.5 g/t gold and 6.5 g/t silver and core hole NB-12-126 intersecting 11.4 metres @ 4.9 g/t gold and 7.0 g/t silver. Core hole NB-12-127 (7.7 metres @ 2.4 g/t gold and 11.31 g/t silver) was designed to follow up on an interesting intersection in RC hole NB-11-91 (9.1 metres @ 2.07 g/t gold and 2.32 g/t silver) which was the first time quartz vein related mineralization was encountered.
These results were used to target the hotter boiling zone part of the quartz vein system which lead to the Yellow Jacket discovery in hole NB-12-138 (72.4 metres @ 1.74 g/t gold and 98.7 g/t silver including 4.3 metres @ 20 g/t gold and 1,519 g/t silver).
In the just completed 4 hole program, Hole NB-12-181 targeted the down dip projection of the veins in NB-12-138. However, structural displacements related to a NE-trending fault (now known as the Mai Fault) made it difficult to correlate the geology of the two holes (Figure 1, Table 1). Hole NB-12-182 was drilled approximately 50 metres south of NB-12-138/181 with the objective of better defining the location and nature of the NE-trending structure encountered in NB-12-181. This hole encountered stockwork veining with low-grade gold over significant intervals (Table 1) and succeeded in defining the Mai fault (Figure 1). Delineation of the Mai Fault allowed the plunge of the intersection of the Mai and Blind faults to be calculated and holes NB-12-183 and NB-12-184 were designed to drill perpendicular to the plunge of that intersection and successfully hit the target which appears to have an expanding vein system at depth that could hold the real potential of the system intersected to date (Figure 2).

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 Corporation. The property package is made up of a number of leased 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 Company's independent consultants completed a robust positive Preliminary Economic Assessment on the existing resource in December 2012.
The project currently includes numerous prospective gold targets, with four (Mayflower, Sierra Blanca, Jolly Jane and Connection) containing an 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 Yellow Jacket targets. The Company is actively pursuing both types of mineralization.

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.
