Corvus Gold Returns 185m @ 0.82 g/t Gold incl. 14.6m @ 3.4 g/t Gold from the Lynnda Strip and 14.5m @ 6.48 g/t Gold & 25.9 g/t Silver from Mother Lode in the Eastern Bullfrog Gold District, Nevada

Rhea-AI Summary

Corvus Gold Inc. (TSX: KOR, NASDAQ: KOR) announced significant drill results from its Mother Lode and Lynnda Strip gold discoveries. Drill holes ML20-183CT and ML20-185CT at Lynnda Strip revealed gold grades of 0.79 g/t and 0.82 g/t over substantial intervals, indicating a robust mineralization potential. In the Mother Lode, holes ML20-174CT and ML20-175CT showed high-grade intervals of 2.57 g/t and 6.48 g/t gold. These results support upcoming mineral resource estimates and highlight the eastern Bullfrog District's potential for large-scale gold production as Corvus maintains strong financial health.

Positive

• Drill holes at Lynnda Strip showed consistent high gold grades (up to 3.32 g/t) and substantial intervals (up to 185.4m) indicating a strong oxide deposit.
• High-grade intervals reported from Mother Lode drill holes suggest increased gold concentration near the property boundary, enhancing resource potential.
• Corvus maintains a strong financial position and nears production at the North Bullfrog project, positioning the company for significant growth in the Bullfrog Mining District.

Negative

• The northern extension of the Mother Lode system may be thinning, which could pose challenges for future resource estimates.

VANCOUVER, British Columbia, May 18, 2021 (GLOBE NEWSWIRE) -- Corvus Gold Inc. (“Corvus” or the “Company”) - (TSX: KOR, NASDAQ: KOR) announces it has received additional drill holes results from the Mother Lode and Lynnda Strip oxide gold discoveries (Table 1, Figure 1). Corvus believes that these results will be an important addition to a maiden mineral resource estimate for Lynnda Strip and an updated Mother Lode mineral resource estimate scheduled for later in the year. The mineralization defined in these drill holes continues to support the large potential in the eastern Bullfrog District along the Mother Lode to Silicon belt. Corvus remains focused on assessing its strategic property package along this belt by expanding its currently defined deposits as well as new target opportunities.

Lynnda Strip
Drill holes ML20-183CT (180m @ 0.79 g/t Au) and ML20-185CT (185.4m @ 0.82 g/t Au) continue to demonstrate the thick and consistent nature of the large oxide, Lynnda Strip deposit. In addition, these holes have continued to expand the broad, higher grade internal vein systems within the bulk tonnage deposit (ML20-183CT: 21.5m @ 3.32 g/t Au & 17m @ 1.1 g/t Au and ML20-185CT: 14.6m @ 3.4 g/t Au & 6.4m @ 1.41 g/t Au). The currently defined vein systems that Corvus has identified at Lynnda Strip appear to be coalescing toward a large new structure target at depth, which is feeding the overall Lynnda Strip deposit. One key element of this new high-grade target is the structural system between the Lynnda Strip and South Merlin deposits (Wizard Fault), immediately west of hole ML20-185CT which is currently being tested.

Mother Lode
Drill holes ML20-174CT (26.7m @ 2.57 g/t Au & 6.08 g/t Ag including 7.3m @ 4.70 g/t Au & 9.87 g/t Ag), and ML20-175CT (14.5m @ 6.48 g/t Au & 25.9 g/t Ag), continues to expand the North Feeder Zone and are approximately 200 metres north of drill holes ML20-160CT (30.2m @ 1.42 g/t Au & 86.9m @ 1.65 g/t Au) and ML20-176CT (110.8m @ 1.68 g/t Au, including 58.7m @ 2.47 g/t Au) from NR21-04, February 9, 2021. The new holes are suggesting the northern extension of the Northern Feeder Zone may be thinning but increasing in grade as we approach the Corvus property boundary, which is about 250 metres north of hole ML20-174CT. At this point it appears that the northern extension of the Mother Lode system could be transitioning into an underground target that could potentially be accessed out the bottom of an open pit.

Jeffrey Pontius, President and CEO of Corvus, said, “With Corvus’ latest drill hole results we continue to add to the potential of the Eastern Bullfrog District along the productive Mother Lode to Silicon Belt. With the numerous discoveries and positive drill results that have been returned from the Eastern Bullfrog District, it appears this area is shaping up to host a large production center that could involve all major land owners in the area. With Corvus’ strong financial position and near-term production asset at North Bullfrog, the Company is well positioned to play a key role in the re-development of the Bullfrog Mining District.”

All statements, other than statements of historical fact, included herein including, without limitation, statements regarding the possible events, conditions or financial performance that is based on assumptions about future economic conditions and courses of action; timing for an updated mineral resource estimate; potential expansion of the deposit; the rapid and effective capture of the potential of our projects; the potential for new deposits and expected increases in the system’s potential; anticipated content, commencement and cost of exploration 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 projects; and the potential for any mining or production at the 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 2020 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.

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.

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.

The United States Securities and Exchange Commission (“SEC”) limits disclosure for U.S. reporting purposes to mineral deposits that a company can economically and legally extract or produce. Resource estimates contained in this press release are made pursuant to NI 43-101 standards in Canada and do not represent reserves under the standards of the SEC’s Industry Guide 7. Under the currently applicable SEC Industry Guide 7 standards, a “final” or “bankable” feasibility study is required to report reserves, the three-year historical average price is used in any reserve or cash flow analysis to designate reserves and all necessary permits and government approvals must be filed with the appropriate governmental authority. This press release uses the terms “Measured Resources”, “Indicated Resources”, and “Inferred Resources”. We advise U.S. investors that while these terms are Canadian mining terms as defined in accordance with NI 43-101, such terms are not recognized under SEC Industry Guide 7 and normally are not permitted to be used in reports and registration statements filed with the SEC. Mineral resources described in this press release have a great amount of uncertainty as to their economic and legal feasibility. 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 measures. “Inferred Resources” have a great amount of uncertainty as to their existence, and great uncertainty as to their economic and legal feasibility. It cannot be assumed that any or all part of an Inferred Resource will ever be upgraded to a higher category. U.S. Investors are cautioned not to assume that any part or all of mineral deposits in these categories will ever be converted into SEC Industry Guide 7 reserves.
