Highlights: 108m @ 0.57 g/t Gold, Including: 20m @ 0.99 g/t Gold
VANCOUVER, BRITISH COLUMBIA--(Marketwired - Feb 7, 2017) - Corvus Gold Inc. ("Corvus" or the "Company") - (TSX:KOR) (OTCQX:CORVF) announces the initial results from the first five holes in the new Liberator Zone immediately east of the Company's Sierra Blanca-YellowJacket resource (Figure 1). Results continue to outline a broad zone of gold mineralization as four of the five holes returned wide mineralized intercepts. Drill Hole NB16-320 intercepted broad gold mineralization starting at a shallow depth below surface returning 108 metres @ 0.57 g/t gold including higher grade vein intercepts of 1.52 metres @ 8.3 g/t Gold & 1.52 metres @ 4.96 g/t gold (Table 1) and ending in mineralization.

Jeff Pontius, President and CEO of Corvus said, "The initial results from drilling on the Liberator Zone has opened up a large new area of gold-silver mineralization at the North Bullfrog project. These results have led to a reinterpretation of numerous high and low grade intercepts immediately east of our current resource, now defining a sizable new structural zone stretching for over 800 metres in length. We believe that this new zone holds potential for another high-grade body like that at YellowJacket and its proximity to the current designed pit could make it an important resource expansion target. We believe the ongoing drill program is progressing toward its goal of expanding the existing resource and testing other new gold discoveries on this new Nevada, district scale, gold deposit."
Liberator Zone
The Liberator Zone is parallel to the YellowJacket deposit and has about the same strike length at nearly one kilometre. Although the Liberator and YellowJacket structural zones are parallel they dip in opposite directions with the YellowJacket dipping to the west and the Liberator dipping to the east, which led to the Liberator not being effectively tested in the past during the east directed YellowJacket drilling programs. The new Liberator discovery like the YellowJacket has returned drill intersections of shallow, higher grade gold mineralization (NB-15-267, 11m @ 3.5 g/t Au, NR15-14, Oct. 15, 2015; NB-13-350, 6m @ 2.4 g/t Au, NR13-25, Oct. 10, 2013; NB-12-126, 5.7m @ 6 g/t Au, NR12-10, Mar. 22, 2012; NB-10-63, 14m @ 6 g/t Au, NR11-03, Feb. 1, 2011). In addition, the Liberator also hosts broad zones of lower grade mineralization highlighting the extensive fluid flow of gold and silver rich solutions in this large structural zone (NB-16-320, 108m @ 0.57 g/t Au; NB-16-303, 154m @ 0.54 g/t Au, NR16-11, Aug. 2, 2016; NB-15-267, 210m @ 0.47 g/t Au, NR15-14, Oct. 15, 2016; low grade halo around high-grade zone).
The holes reported in this news release are infill holes that have added continuity to the overall Liberator mineralized zone and importantly have now defined its northern extension (NB-16-315 6.1m @ 1.06 g/t Au and 6.1m @ 1.14 g/t Au) below the intercept in hole NB-16-300 with 18m @ 1.8 g/t Au. These results from the northern Swale Zone now shows a direct connection to the main east dipping Liberator zone to the south. This work also highlights a 250 metre section of the structure that is essentially untested down to the Rhyolite Zone, which hosts high-grade gold and silver mineralization. The higher-grade parts of the Liberator system are related to quartz stockwork and sulfidized zones at intersections with northeast structures, forming shoots within the very broad and extensive structurally controlled low-grade system. Follow-up drilling on the zone is being planned.
Deep High-Grade Target
The refinement of the strike and dip of the new Liberator Zone along with deep drilling success announced late last year at YellowJacket (NB-16-314, 10.7m @ 2.41 g/t Au & 9.7 g/t Ag, NR16-14, Nov. 29, 2016) has now outlined new deep target potential for the Sierra Blanca/YellowJacket deposit. The deep targets are located where the large YellowJacket and Liberator structural zones intersect the underlying low angle, West Jolly Jane Fault at depths of 400-500 metres (Figure 2). This geologic target is analogous to the Hishikari deposit in Japan which hosts large high-grade, gold-silver deposits along major structural zones at the contact between underlying basement sediments and overlying volcanic units. Follow-up core drilling of this target is planned for the next phase of North Bullfrog exploration later this year.

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 potential for new deposits and expected increases in a systems potential; anticipated content, commencement and cost of exploration programs, anticipated exploration program results, the discovery and delineation of mineral deposits/resources/reserves, the potential to develop multiple YellowJacket style high-grade zones, the Company's belief that the parameters used in the Whittle™ pit optimization process are realistic and reasonable, the potential to discover additional high grade veins or additional deposits, the potential to expand the existing estimated resource at the North Bullfrog project, the potential for any mining or production at North Bullfrog, are forward-looking statements. Information concerning mineral resource estimates may be deemed to be forward-looking statements in that it reflects a prediction of the mineralization that would be encountered if a mineral deposit were developed and mined. 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 2014 Annual Information Form and latest interim Management Discussion and Analysis filed with certain securities commissions in Canada and the Company's most recent filings with the United States Securities and Exchange Commission (the "SEC"). All of the Company's Canadian public disclosure filings in Canada may be accessed via www.sedar.com and filings with the SEC may be accessed via www.sec.gov 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 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.
