VANCOUVER, British Columbia, Sept. 18, 2018 (GLOBE NEWSWIRE) -- Corvus Gold Inc. (TSX: KOR, OTCQX: CORVF) (“Corvus” or the “Company”) announces the maiden Mineral Resource estimations incorporating all drill results from the Phase I & II drill programs at its 100% owned Mother Lode Project (“MLP”).  This initial Mineral Resource remains open in several directions and Corvus is currently engaged in its Phase III drill program that is targeting Mineral Resource growth beyond this initial estimate. The Mineral Resources estimations (Measured, Indicated and Inferred) were based on economic constraints using Whittle ^TM software and assuming open pit mining and USD $1,250 per ounce gold price (Table 1).  Figure 1 & 2 shows a plan view and a north-south long-section through the resource block model. 

Table 2 illustrates the robustness of the current project at lower gold prices with a Mineral Resource estimate using a USD $1,000 per ounce gold price which still captures a measured and indicated Mineral Resource of over one million ounces.

Jeff Pontius, the Company’s President & CEO states, “The Mother Lode Deposit has delivered a robust maiden Mineral Resource that exceeded our initial expectations and enlarges the overall Corvus Gold Nevada asset base.  The grade and low strip ratio of this deposit makes it an excellent addition to the North Bullfrog project (NBP) and will add to the combined NBP & MLP initial PEA study expected next month.  The Mother Lode deposit remains open and continues to grow with our ongoing Phase III drill campaign building toward the next multi-million-ounce Nevada discovery.  Additionally, the critical mass provided by the Mother Lode deposit for a sulfide circuit opens the door for the large, high-grade sulfide potential at the North Bullfrog project which has yet to be explored."

The Mineral Resource estimation is based on 267 drill holes with 8,296 gold composites. Geologic volumes were defined by geologic interpretations and used to define the estimation.

The resource was characterized by a high-grade core surrounded by lower grade mineralization. The high-grade core was estimated using Inverse Distance Squared. The surrounding mineralized portion of the deposit was estimated with Ordinary Kriging. To estimate the reasonable prospects of eventual economic extraction, Resource Development Associates Inc. confined the resources to mining volumes defined by Whittle ^TM analysis using the input parameters defined in Table 3. There are no known legal, political or environmental risks that could materially affect the potential development of the Mineral Resources.

New Resource Calculation

The Mineral Resource estimation is based on 189 validated historical drill holes combined with an additional 78 holes drilled by Corvus during the 2017 and 2018 drilling campaigns.  Assays were composited to 8,296 5-meter composites.  Gold assays were capped at 8 g/t Au prior to compositing.  Mineralization is bimodal with a clear high-grade corridor.  The high-grade corridor was constrained to control the impact of high grades on the Mineral Resource estimate.

This Mineral Resource has been estimated in accordance with the disclosure standards of National Instrument 43-101 – Standards of Disclosure for Mineral Projects (“NI 43-101”) using a gold price of USD $1,250 per ounce. Mineral Resources are pit constrained in order to demonstrate the reasonable prospects of eventual economic extraction. Mineralization has been classified according to NI 43-101 as Measured Mineral Resources, Indicated Mineral Resources and Inferred Mineral Resources.

A technical report with respect to the Mineral Resource estimate disclosed herein will be filed within 45 days in accordance with NI 43-101.

Cautionary Note to US Investors

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. The mine economics presented herein and derived from the PEA are preliminary in nature and may not be realized. The PEA is not a feasibility study. 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.
