Corvus Gold Receives Encouraging Gold-Silver Leach Recovery Results from Yellow Jacket High-Grade Zone, North Bullfrog Project, Nevada

Gold Recoveries Average 86% & Silver Recoveries Average 77%

TSX: KOR  OTCQX: CORVF

VANCOUVER, June 5, 2013 /CNW/ - Corvus Gold Inc. ("Corvus" or the "Company") - (TSX: KOR, OTCQX: CORVF) announces the results of a series of cyanide bottle roll tests on sample composites from the Yellow Jacket high-grade gold-silver zone, North Bullfrog, Nevada (Table 1).  The results from 22 composites throughout the currently defined high-grade area averaged recoveries of 86% for gold and 77% for silver with very low cyanide and lime consumption for material averaging 3.0 g/t gold and 29.0 g/t silver (Table 2). The drill results to date from the Yellow Jacket Zone have yet to be incorporated into the current resource estimate and preliminary economic assessment (NR13-13, June 4, 2013) and include: NB 12-138, 72.4m of 1.74 g/t gold & 98.7 g/t silver, including 4.3m of 20.0 g/t gold & 1,519 g/t silver (see NR12-20). The Company is planning to complete an updated resource estimate and preliminary economic assessment in late 2013 incorporating the results from the current drill program, new metallurgical data and past results from the Yellow Jacket zone.

The bottle roll tests were run for 96 hours and displayed characteristics of continuing metal recovery suggesting that ultimate recoveries had not been reached. Subsequent longer term tests on coarser fractions are in progress. Initial data indicates mineralization starts at 40m depth and extends to at least 130m, which suggests that this high-grade zone might be amenable to standard low cost open pit mining and heap leach gold-silver recovery, and could form the nucleus of a large starter pit phase that has yet to be included in the mining project model.

The silver recoveries from the Yellow Jacket zone are significantly higher than the 8% average recovery found at the other zones of the North Bullfrog project as described in the Company's latest preliminary economic study (NR13-13, June 4, 2013).  The new recovery data is relatively uniform across oxidation, veining and wall rock types, suggesting that the observed hotter system temperatures have eliminated the effect of sulfide on recovery.  This is encouraging, as recent exploration work is defining a much hotter system to the north.

The Yellow Jacket Zone is a large emerging high-grade target discovered in 2012 and is the focus of the Company's 2013 diamond drilling program.  Current work has been directed at extending the Yellow Jacket system to the north by approximately 1 kilometre. The currently defined 700 metre long zone at Yellow Jacket is approximately 100 metres wide, has been tested to a depth of 130 metres and remains open in all directions.  To date, four step-out holes covering a 100 metre northern extension have been completed, and these have continued to intersect favourable veining and alteration (assays pending).  In addition, ongoing reverse circulation drilling half a kilometre north of the currently defined Sierra Blanca deposit is focused on expanding higher grade mineralization discovered in the 2012 scout drilling program.

Carl Brechtel, COO of Corvus, stated: "The new Yellow Jacket heap leach results are very encouraging and suggest the potential to add a large high-grade starter pit component to our existing North Bullfrog deposit.  The effect of the higher grade, early mining phase could be significant, as it will benefit from the low open pit mining and heap leach production costs. These results continue to enhance the North Bullfrog project and support the significant potential for developing Nevada's next new gold mine."

About the North Bullfrog Project, Nevada

Corvus controls 100% of its North Bullfrog Project, which covers approximately 70 square kilometres 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.

The project currently includes numerous prospective gold targets with four (Mayflower, Sierra Blanca, Jolly Jane and Connection) containing an estimated Oxidized Indicated Resource of 36.7 Mt at an average grade of 0.26 g/t gold for 307,860 ounces of gold and an Oxidized Inferred Resource of 220.7 Mt at 0.18 g/t gold for 1,288,970 ounces of gold (both at a 0.1 g/t gold cutoff), with appreciable silver credits.  Unoxidized Inferred mineral resources are 221.6 Mt at 0.19 g/t for 1,361,000 ounces of gold (at a 0.1 g/t gold cutoff).

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 by structural 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.

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.

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.
