Corporate Update and Plans for 2023-2024 June 2023 NYSE-A: CTGO Building Alaska’s Next Gold Mines Exhibit 99.1

FORWARD LOOKING STATEMENT The Feasibility Study (“FS”) referenced herein that relates to Peak Gold, LLC (“Peak Gold”), was prepared by Kinross Gold Corporation (“Kinross”), which controls the Manager of Peak Gold and holds 70% of its outstanding membership interests, in accordance with Canadian National Instrument 43-101 (NI 43-101). CORE owns the remaining 30% membership interest in Peak Gold, and must rely on Kinross and its affiliates for the FS and related information. Further, CORE is not subject to regulation by Canadian regulatory authorities and no Canadian regulatory authority has reviewed the FS or passed upon its accuracy or compliance with NI 43-101. The terms “mineral resource”, “measured mineral resource”, “indicated mineral resource” and “inferred mineral resource” as used in the resource estimate, the FS and this presentation are Canadian mining terms as defined in accordance with NI 43-101. Mining disclosure in the United States was previously required to comply with the U.S. Securities and Exchange Commission’s (the “SEC”) Industry Guide 7 (“SEC Industry Guide 7”) under the United States Securities Exchange Act of 1934, as amended. The SEC adopted final rules to replace SEC Industry Guide 7 with new mining disclosure rules under sub-part 1300 of Regulation S-K of the U.S. Securities Act (“Regulation S-K 1300”), which became mandatory for U.S. reporting companies beginning with the first fiscal year commencing on or after January 1, 2021. Under Regulation S-K 1300, the SEC now recognizes estimates of “Measured Mineral Resources”, “Indicated Mineral Resources” and “Inferred Mineral Resources”. In addition, the SEC has amended its definitions of “Proven Mineral Reserves” and “Probable Mineral Reserves” to be substantially similar to international standards. Under Regulation S-K 1300, an SEC registrant with material mining operations must disclose specified information in its SEC filings concerning mineral resources, in addition to mineral reserves, which have been determined on one or more of its properties. Such mineral resources and reserves are supported by a technical report summary (the “S-K 1300 Report”), which is dated and signed by a qualified person or persons, and identifies and summarizes the information reviewed and conclusions reached by each qualified person about the SEC registrant’s mineral resources or mineral reserves determined to be on each material property. CORE is in the process of preparing an S-K 1300 Report based on the FS. Investors are cautioned that while the Regulation S-K 1300 definitions are “substantially similar” to the NI 43-101 definitions, there are differences between the two. Accordingly, there is no assurance any mineral reserve or mineral resource estimates that CORE may report as “probable mineral reserves”, “measured mineral resources”, “indicated mineral resources” and “inferred mineral resources” under NI 43-101 would be the same had CORE prepared the mineral reserve or mineral resource estimates under the standards adopted under Regulation S-K 1300. Further, U.S. investors are also cautioned that while the SEC recognizes “measured mineral resources”, “indicated mineral resources” and “inferred mineral resources” under Regulation S-K 1300, investors should not assume that any part or all of the mineralization in these categories will ever be converted into a higher category of mineral resources or into mineral reserves. Mineralization that has been characterized as resources has a greater degree of uncertainty as to its existence and feasibility than mineralization that has been characterized as reserves. Accordingly, investors are cautioned not to assume that any measured mineral resources, indicated mineral resources or inferred mineral resources that CORE reports are or will be economically or legally mineable. Please see the CORE's press release dated May 26, 2023 for more detail regarding the FS; and Kinross' July 27, 2022 and second quarter results: 2 https://www.contangoore.com/press-release/contango-ore-announces-completion-of-s-k-1300-technical-report-summary-for-its-manh-choh-project-in-alaska and : https://www.kinross.com/news-and-investors/news-releases/press-release-details/2022/Kinross-reports-2022-second-quarter-results/default.aspx;

This presentation contains forward looking estimates of all-in sustaining cost (“AISC”), resources and EBITDA, which are a financial measure not determined in accordance with United States generally accepted accounting principles (“GAAP”). We cannot provide a reconciliation of estimated AISC, resources, EBITDA and cash flow to estimated costs of goods sold, assets and net income, which are the GAAP financial measures most directly comparable to such non-GAAP measures, without unreasonable efforts due to the inherent difficulty and impracticality of quantifying certain amounts that would be required to calculate projected AISC, resources, EBITDA. In addition, the estimates of AISC, resources and EBITDA have been prepared by Kinross and are based on IFRS accounting standards and detailed information to which the Company has not had access to at this time. These amounts that would require unreasonable effort to quantify could be significant, such that the amount of projected GAAP cost of goods sold, assets and net income would vary substantially from the amount of projected AISC, resources and EBITDA. 33 NON-GAAP RECONCILIATION DISCLAIMER APPENDIX
