Corvus Gold Begins Phase II Exploration Drill Program, North Bullfrog Project, Nevada

TSX: KOR  OTCQX: CORVF

VANCOUVER, Aug. 11, 2015 /CNW/ - Corvus Gold Inc. ("Corvus" or the "Company") - (TSX: KOR, OTCQX: CORVF) announces the start of its Phase II 2015 drill program at the North Bullfrog Project, Nevada on August 11th. The 8,000 metre reverse circulation (RC) drill program will focus on two main areas 1) Testing new high-grade discovery targets in the large unexplored Eastern Steam-heated Zone; 2) Defining new high-grade systems similar to the recent YellowJacket discovery in and around the large resource areas in the NW part of the property (Figure 1).  The program will follow-up on new geologic, structural and mineralization results from the initial spring 2015 phase I drilling program.

Jeff Pontius, President and CEO of Corvus Gold Inc. said "The positive results from Corvus Gold's preliminary economic assessment which incorporates the new high-grade YellowJacket discovery have demonstrated the high potential of the North Bullfrog District. New surface and drill hole exploration data linked to the gold depositional controls defined at YellowJacket has now outlined a number of prospective new discovery and potential resource expansion targets across the District.  The two pronged phase II drill program will focus on the evaluation of near-term high-grade resource expansion in the west and new large deposit discovery potential in the east.  We believe that the large new Eastern Steam-heated target area which covers some fourteen square kilometres has the potential to host additional YellowJacket or Bullfrog-type deposits.  This next round of exploration at North Bullfrog holds the potential to expand an existing, highly prospective, high margin deposit."

Western Target Areas 

The phase II drill program will test a number of priority new discovery and resource expansion targets in and around the existing North Bullfrog deposits (Figure 2).  Two of these targets were tested in the early 2015 phase I, "proof of concept" drilling program, the results of which have confirmed the key structural and mineralization controls.  At the North Sierra Blanca target a northeast trending high level stockwork vein system returned +1 g/t gold intercepts from high level stockwork veining over several meters.  This new vein system appears to mirror the YellowJacket zone some 400 metres to the west (NR15-08: July 9, 2015).  At the Liberty target which is 500 metres south of the YellowJacket deposit, drilling has intersected a high level quartz stockwork vein system with high mercury values and low grade gold and silver which is characteristic of the tops of the YellowJacket system.  Follow up drilling will be conducted at both targets to evaluate these new stockwork systems at depth in the projected productive zones.

In addition, a number of other structural/high-grade targets will be tested in the greater Sierra Blanca and Jolly Jane areas including the Air Track/366 target (following up hole NB-13-366 with 20m of 1.03 g/t Au & 17.5m @ 1.26 g/t Au under shallow pediment cover, NR14-01, January 9, 2014) and North YellowJacket (Rhyolite Vein 11.3m @ 3.3 g/t Au, NR14-17: September 4, 2014).  The setting of the Jolly Jane is similar to the Sierra Blanca/YellowJacket deposits with two major bounding structural zones on the east and west sides of a large low-grade deposit.  It is believed that these structural zones could host similar high-grade mineralization to that at YellowJacket and will be initially tested in the phase II program.

Eastern Steam-heated Zone

Ongoing mapping and surface exploration has now expanded the Eastern Steam-heated alteration zone to 7 km along strike and approximately 2 km in width.  The core of this expanding target area has now been covered with a detailed soil survey with initial results indicating new areas of anomalous gold-silver mineralization linked to the major through going structures (Figure 3).  These new soil results will be an important addition to defining the location, scale and priority of phase II drill targets in the Eastern Zone as they link the large highly altered structural zones with potentially productive gold-silver mineralization.

Drilling at the Eastern Zone will start with the initial testing of the first group of target areas including: Alunite Hill, Spicerite Graben, Vinegaroon and Cat Hill.  These areas each include several individual targets each with potential to host significant deposits.  The Eastern Zone is an exploration opportunity over a District scale system that remains essentially unexplored.  Recent exploration work and analysis of the Eastern Steam-heated Zone by Dr. Richard Sillitoe, has refined and enhanced the targeting process and highlighted the potential of the belt in the context of other large productive epithermal belts in the world.  Dr. Sillitoe has been an important contributor to discoveries like the Fruta del Norte deposit in Equator, El Pinion deposits in Chile and Cerro Vangardia deposits in Argentina as well as many more.

About the North Bullfrog Project, Nevada

Corvus controls 100% of its North Bullfrog Project, which covers approximately 72 km² in southern Nevada.  The property package is made up of a number of private mineral leases of patented federal mining claims and 865 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.

The North Bullfrog project includes numerous prospective gold targets at various stages of exploration with four having NI 43-101 compliant mineral resources (Sierra Blanca, Jolly Jane, Mayflower and YellowJacket).   The project contains a measured mineral resource of 3.86 Mt at an average grade of 2.55 g/t gold and 19.70 g/t silver, containing 316.5k ounces of gold and 2,445k ounces of silver, an indicated mineral resource of 1.81 Mt at an average grade of 1.53 g/t gold, and 10.20 g/t silver, containing 89.1k ounces of gold and 593.6k ounces of silver and an inferred resource of 1.48 Mt at an average grade of 0.83 g/t gold and 4.26 g/t silver, containing 39.5k ounces of gold and 202.7k ounces of silver for oxide mill processing.  The mineral resource for the mill process was defined by WhittleTM optimization using all cost and recovery data and a breakeven cut-off grade of 0.52 g/t gold. In addition, the project contains a measured mineral resource of  0.3 Mt at an average grade of 0.25 g/t gold and 2.76 g/t silver, containing 2.4k ounces of gold and 26.6k ounces of silver, an indicated mineral resource of 22.86 Mt at an average grade of 0.30 g/t gold and 0.43 g/t silver, containing 220.5k ounces of gold and 316.1k ounces of silver and an inferred mineral resource of 176.3 Mt at an average grade of 0.19 g/t gold and 0.67 g/t silver, containing 1,077.4k ounces of gold and 3,799.2k ounces of silver for oxide, heap leach processing. The mineral resource for heap leach processing was defined by WhittleTM optimization using all cost and recovery data and a breakeven cut-off grade of 0.15 g/t.  Mineral resources that are not mineral reserves do not have demonstrated economic viability.

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 investors 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. U.S. investors are urged to consider closely the disclosure in our latest reports and registration statements filed with the SEC. You can review and obtain copies of these filings at http://www.sec.gov/edgar.shtml. U.S. Investors are cautioned not to assume that any defined resource will ever be converted into SEC Industry Guide 7 compliant reserves.

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.
