VANCOUVER, Oct. 1, 2012 /CNW/ - Corvus Gold Inc. ("Corvus" or the "Company") - (TSX: KOR, OTCQX: CORVF) announces the start of its follow up drill program on the high-grade gold target at Yellow Jacket on its North Bullfrog project in Nevada. The program will target the down dip extension of core zone mineralization that was intersected in the Company's recent hole NB12-138 (4.3 metres at 20.0 g/t gold and 1,519 g/t silver).
Results from a recently completed 3D IP geophysical survey at North Bullfrog has provided important targeting information for follow up drilling. In addition to targets at Yellow Jacket, results have highlighted a number of other highly favourable structural zones with high-grade potential on the property (Figure 1). In addition, this survey has further defined favourable areas for the expansion of the bulk tonnage deposits in the North Area. The drilling program will begin with one diamond core rig and expand when new permits are received at the end of the year.
Jeff Pontius, Corvus Gold CEO states: "Follow-up drilling is opening up an exciting new value component for the project and our Company as a whole. The new high-grade targeting information has identified a number of highly encouraging targets that indicate expansion potential of both high-grade and bulk tonnage mineralization outside the current defined area."
Yellow Jacket Target
The Yellow Jacket target is associated with an intensely fractured, deep seated north-south trending fault zone. This zone hosts a variety of vein related high-grade gold and silver mineralization with a large surrounding, low-grade, disseminated zones. There are two important types of veins. Single stage quartz veins with pyrite have been encountered in holes NB-12-126 (5.7 metres of 6.56 g/t gold and 9.94 g/t silver) and NB-12-127 (7.7 metres of 2.43 g/t gold and 11.31 g/t silver) while more complex silicified hydrothermal breccias with fragments of banded colloform quartz were encountered in hole NB-12-138 (4.3 metres of 20.0 g/t gold and 1,519 g/t silver). Analysis of vein textural variations together with variations in clay mineralogy is helping to unravel the mechanics of this kilometer long structural zone that hosts significant high-grade mineralization. The follow up drill program will initially focus on expanding and defining the geometry of the core zone mineralization but will then begin to look at other high priority targets in the District.
District High-Grade Potential
Surface sampling, drilling and the new geophysical study have highlighted several high potential areas for both expansions of the current oxide heap leach resource and undiscovered high-grade systems. Historically several high-grade vein systems where mined at the turn of the century in the North Bullfrog District with similarities to the veins mine by Barrick Gold in the 1990's at the Bullfrog Mine 8 kilometres south. New priority high-grade targets have been identified at the Road Fault, West Sierra Blanca and West Savage Valley which will be tested following the next phase of Yellow Jacket drilling. In addition, targeting work is ongoing in the Mayflower area to follow up the new high-grade, banded adularia vein discovery (NB-12-141 with 1.1 metres of 6.85 g/t gold and 1.9 g/t silver).
New 3D Induced Polarization Geophysical Survey
The 3D induced polarization survey, conducted by SJ Geophysics, was designed to provide information about the structure and alteration around the North Area deposits. The survey consisted of 36 line kilometres which has provided 3D coverage over an area of 5.6km². The primary objective of the survey was to define the locations of key structures related to high-grade vein type mineralization, particularly in the Yellow Jacket area. In addition the survey has mapped key stratigraphic controls and alteration associated with the large bulk tonnage deposits in the area. The final 3D inversion was received in mid-September and the data has played an important role in the targeting of follow-up drilling programs for both the high-grade program and the extension of existing oxide heap leach resources
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.

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.
