Corvus Gold Inc. (“Corvus” or the “Company” – https://www.commodity-tv.com/ondemand/companies/profil/corvus-gold-inc/) – (TSX: KOR, NASDAQ: KOR) announces results for its Preliminary Economic Assessment (“PEA”) of the Company’s Mother Lode Project (MLP) in southwest Nevada (Figure 1).  Results outline a potential large Nevada, standalone, mining project with attractive preliminary production and financial performance statistics.  This project is expected to be the Company’s second and separate mine development target in a central location surrounded by other recent discoveries in the Bullfrog Mining District.

The initial PEA does not take into account any potential synergies and cost savings from having the North Bullfrog project approximately 10km’s away on the basis that the MLP is viewed as a 100% standalone property and development project, with its own timeline and infrastructure.  The results indicate robust economics at a gold price of $1,500/oz with pre-tax free cash flow of USD $564M and post-tax NPV5% of USD $303M with an IRR of 23% and strong leverage for higher gold prices with a USD $1.11B pre-tax cash flow at $1,900 gold price and post-tax NPV5% of USD $663M with an IRR of 42% (Table 1). The Mother Lode Project may provide Corvus with a future production growth option to increase its gold production profile in the Bullfrog Mining District beyond its initial mining project at North Bullfrog. MLP could position Corvus for expanding organic production growth and possible further District consolidation of other assets.   

The Mother Lode PEA is preliminary in nature, and includes inferred mineral resources that are considered too speculative geologically to have the economic considerations applied to them that would enable them to be categorized as mineral reserves, and there is no certainty that the PEA will be realized.  Mineral resources that are not mineral reserves do not have demonstrated economic viability.

Jeffrey Pontius, President and CEO of Corvus states, “The results from our initial PEA study of the Mother Lode standalone project are encouraging.  The potential projected annual gold production of over 200,000 ounces per year during the first 3 years is significant, especially as a new project, which could provide an increase to the Corvus Gold future production profile. The PEA demonstrates the preliminary potential for the project, on its own, to produce significant free cash flow and after tax NPV5%.  Corvus now has a number of strategic alternatives available to it to drive shareholder value.  Given the recent interest in the Bullfrog Gold District from multiple producing Companies with adjacent land packages, Corvus’ compelling and accretive projects and its commanding land position with what we believe is demonstrated high exploration potential, has positioned the Company to deliver increased shareholder value.”  

The Mother Lode Project is modeled as a large, open-pit, with a biological oxidation mill to treat the higher-grade sulphide mineralization and a heap leach pad for treatment of oxide mineralization.  The mining plan utilizes standard mining practices and has a production scale that is currently being used by many operating mines.  The updated Mother Lode mineral resource estimate is shown in Table 5.    

The new PEA study, which assumes a standalone project, also includes a number of other changes to the previously assumed concept for the combined Mother Lode-North Bullfrog project configuration which enhance the project that include:

  • Employing biological oxidation (BiOx) to treat the MLP sulphide mineralization would increase gold recovery by 11%. Metallurgical testing of a stirred BiOx process on the MLP whole sulphide mineralization from Mother Lode demonstrated gold recoveries of 91-92% as compared to the previous testing on MLP flotation concentrate.
  • Eliminating the need for the concentrator, oxygen plant and autoclave components of the previous plant concept simplified the plant conceptual design and would reduce the process plant capital cost.
  • Ongoing work expanding Mother Lode resources in the CIZ area and the main Zone with ongoing work at improving the open-pit mining and development plans will enhance project economics.
  • New experimental work on conducting the BiOx process in a heap is being tested as follow-up on past successful studies and could substantially cut operation and capital costs with the elimination of the mill circuit.

The PEA only includes drill results completed up until September 2020.  In addition, Corvus will continue follow-up mineral resource expansion work and new discovery drilling on priority targets at both the North Bullfrog and Mother Lode properties through 2021.

This news 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 economics and project parameters presented in the PEA, including, without limitation, IRR, all-in sustaining capital costs (AISC), NPV and other costs and economic information, possible events, conditions or financial performance that is based on assumptions about future economic conditions and courses of action; potential expansion of the deposit; the rapid and effective capture of the potential of our Mother Lode project; the potential for new deposits and expected increases in the system’s potential; anticipated content, commencement and cost of exploration programs; anticipated exploration program results and expansion of existing programs; the discovery and delineation of mineral deposits/resources/reserves; the potential to discover additional high grade veins or additional deposits; the growth potential of the Mother Lode and North Bullfrog projects; and the potential for any mining or production at the Mother Lode  and North Bullfrog projects, 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 2019 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”).  The Company does not undertake to update any forward-looking statements, except in accordance with applicable securities laws.  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.

Non-IFRS Measures

The Company has included certain non-IFRS performance measures as detailed below. In the gold mining industry, these are common performance measures but may not be comparable to similar measures presented by other issuers. The Company believes that, in addition to conventional measures prepared in accordance with IFRS, certain investors use this information to evaluate the Company’s performance and ability to generate cash flow. Accordingly, it is intended to provide additional information and should not be considered in isolation or as a substitute for measures of performance prepared in accordance with IFRS.

Cash Costs per Ounce of Gold – The Company calculates cash costs per ounce by dividing operating expenses per the consolidated statement of operations, net of silver sales by-product revenue, by the gold ounces sold during the applicable period. Operating expenses include mine site operating costs such as mining, processing and administration as well as royalties, however excludes depletion and depreciation and rehabilitation costs.

Sustaining Costs or AISC – The Company defines sustaining costs as the sum of operating cash costs (per above), sustaining capital (capital required to maintain current operations at existing levels), corporate administration costs, sustaining exploration, and rehabilitation accretion and amortization related to current operations. Sustaining costs excludes capital expenditures for significant improvements at existing operations deemed to be expansionary in nature, exploration and evaluation related to growth projects, financing costs, debt repayments, and taxes. 

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/…. 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.
