NYSE-A: CTGO BUILDING ALASKA’S NEXT GOLD MINES June 2023 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). Contango Ore, Inc. (“CORE” or “Contango”) 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. In the United States, mining disclosure is reported under sub-part 1300 of Regulation S-K (“S-K 1300”). Under S-K 1300, the U.S. Securities and Exchange Commission (“SEC”) recognizes estimates of “Measured Mineral Resources”, “Indicated Mineral Resources” and “Inferred Mineral Resources”. In addition, the definitions of “Proven Mineral Reserves” and “Probable Mineral Reserves” are substantially similar to international standards. Under 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 prepared an S-K 1300 Report, dated May 12, 2023, based on the FS, that presented mineral resource estimates and mineral reserve estimates for the Manh Choh project as of December 31, 2022 (the "Manh Choh S-K 1300 Report"). CORE prepared an additional S-K 1300 Report, dated May 26, 2023, based on historical and recent drill hole assay information, that presented mineral resource estimates for the Lucky Shot project as of May 26, 2023 (the "Lucky Shot S-K 1300 Report"). Investors are cautioned that while the 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 Peak Gold 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 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 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. For more detail regarding the FS, please see CORE's press release dated May 26, 2023: 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 Kinross' second quarter 2022 earnings release: 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 and EBITDA 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 and 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 that the Company does not have 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. 31 NON-GAAP RECONCILIATION DISCLAIMER

Lucky Shot Property Historic Resources1 Historic M&I Reserve on Adjacent Coleman Segment of LS Vein: 206k Tonnes @ 18.3 g/t Gold for 121,500 Ounces of Contained Gold2 1 The historical production information presented is based upon reports file by the US Geological Survey from information provided by prior owners and operators of the mines. The Company has not undertaken any independent work to verify or confirm the previously reported information ( see Harlan, et al., 2017 and Stoll, 1997). The historical information may not be representative of future results of the Company’s activities 2 Based on a 2018 pre-feasibility study by Hard Rock Consulting. A qualified person (as defined by Securities and Exchange Commission rules) has not done sufficient work to classify the estimate as a current estimate of mineral resources, mineral reserves or exploration results. The Company is not treating these estimates as current estimates of mineral resources, mineral reserves or exploration results. The historical information may not be representative of future results of the Company’s activities Willow Creek district historically produced 19 metric tonnes or approximately 610,874 troy ounces from ore ranging between 30 and 60g/t making it the third largest historic lode gold producing district in Alaska (Harlan, et al., 2017). Lucky Shot Mine reported 252,000 ozs from 169,000 tons of free-milling ore indicating an average head grade of 40 g/t (1.6 oz/tonne) (Stoll, 1997), with additional production from the Coleman and War Baby mines. 36

Contango Exploration Strategy Plan for Lucky Shot Project Rehab and extend existing Enserch tunnel to explore the Lucky Shot vein down-dip - prep for exploration drilling in three stages: Stage 1a Drift 500 meters along footwall and parallel to vein for detailed in-fill drilling; Stage 1b Continue Enserch tunnel as a ramp into hanging wall side of vein and drill a second panel down dip on Lucky Shot vein Stage 2: Connect Enserch and Lucky Shot tunnels Stage 3: Access historic M&I Resources 1 at Coleman zone by building a ramp from the Enserch level to the Coleman level in an effort to add ounces to the mine plan Evaluate District Scale potential Objective: Define 500,000 ounces of gold resource by drilling Lucky Shot vein down dip and along strike of historically produced 250,000 ounces averaging 40g/t 1 37 1 The historical production information presented is based upon reports filed by the prior owners and operators of the mines. The Company has not undertaken any independent work to verify or confirm the previously reported information.
