Corvus Gold Intersects Higher Grade Gold Zones During Resource Definition Drilling at Mayflower Deposit, North Bullfrog, Nevada

Highlights include: NB-12-147: 25.9 metres of 1.13 g/t gold 
  NB-12-160: 13.7 metres of 1.28 g/t gold 

 

VANCOUVER, Sept. 13, 2012 /PRNewswire/ - Corvus Gold Inc. ("Corvus" or the "Company") - (TSX: KOR) (OTCQX: CORVF) announces initial results from the first 16 holes (Figure 1) of the phase II, 23 hole resource expansion and conversion program at Mayflower Deposit, North Bullfrog Project, Nevada. This program is part of the ongoing Mayflower mine development study that is intended to be the cornerstone of a two stage mine development plan that might potentially see gold production commence in late 2014.

These most recent Mayflower results include high-grade vein related mineralization (NB-12-147 with 3.24 g/t gold over 6.1 metres) indicating the deposit may have additional higher-grade potential at depth (Table 1). Results from drill intersections through historic mine waste rock deposits, such as hole NB-12-150 with 4.6 metres of 4.17 g/t gold, further demonstrate the width potential of the vein related systems in the Mayflower deposit.

The results from the Phase II Mayflower program will be incorporated in an updated resource estimate scheduled for Q4 2012 and will also be used in the planned Mayflower feasibility study proposed to be completed in Q1 2013.

Jeff Pontius, Corvus CEO stated: "Corvus has made significant advancements on the development of the Mayflower deposit and, with the continued excellent results from the ongoing drilling, metallurgical and mine design work, Mayflower is emerging as an exceptional potential mining project.  In addition, Corvus has continued with its targeting work on the Yellow Jacket high-grade gold system and will start follow up drilling on this exciting new, Nevada high-grade vein system within the month."

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 current resource in February 2012.

The project currently includes numerous prospective gold targets with four (Mayflower, Sierra Blanca, Jolly Jane and Connection) collectively 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 Yellowjacket targets.  The Company is actively pursuing both types of mineralization.

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 for a production decision to be made in respect of any of the deposits located at the North Bullfrog project, the potential for any mining of or production from any deposit at the North Bullfrog project following any production decision, the planned completion of and timing for an updated resource estimate and/or feasibility study, whether with respect to the Mayflower Deposit or any other deposit at the North Bullfrog project, the potential for the existence or location of additional high-grade veins, 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 Annual Information Form filed with certain securities commissions in Canada.  All of the Company's 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.
