12. Commitments and Contingencies

Tetlin Lease. The Tetlin Lease had an initial ten-year term beginning July 2008 which was extended for an additional ten years to July 15, 2028, and for so long thereafter as the Peak Gold JV initiates and continues to conduct mining operations on the Tetlin Lease.

Pursuant to the terms of the Tetlin Lease, the Peak Gold JV is required to spend $350,000 per year until July 15, 2028 in exploration costs. The Company’s exploration expenditures through the 2023 exploration program have satisfied this requirement because exploration funds spent in any year in excess of $350,000 are credited toward future years’ exploration cost requirements. Additionally, should the Peak Gold JV derive revenues from the properties covered under the Tetlin Lease, the Peak Gold JV is required to pay the Tetlin Tribal Council a production royalty ranging from 3% to 5%, depending on the type of metal produced and the year of production. In lieu of a $450,000 cash payment to the Peak Gold JV from the Tetlin Tribal Council to increase its production royalty by 0.75%, the Peak Gold JV agreed to credit the $450,000 against future production royalty and advance minimum royalty payments due to the Tetlin Tribal Council under the lease once production begins. Until such time as production royalties begin, the Peak Gold JV must pay the Tetlin Tribal Council an advance minimum royalty of approximately $75,000 per year, and subsequent years are escalated by an inflation adjustment. Production commenced in July 2024 and the Peak Gold JV has started to satisfy the production royalty obligations pursuant to the terms of the Tetlin Lease.

Gold Exploration. The Company’s Triple Z, Eagle/Hona, Shamrock, Willow, Golden Zone, Amanita, Amanita NE and Lucky Shot claims are all located on State of Alaska lands. The annual claim rentals on these projects vary based on the age of the claims, and are due and payable in full by November 30 of each year. Annual claims rentals for the 2024-2025 assessment year totaled $436,258. The Company paid the current year claim rentals in November 2025. The associated rental expense is amortized over the rental claim period, September 1st - August 31st of each year.

Lucky Shot Property. With regard to the Lucky Shot Property, the Company will be obligated to pay CRH Funding II PTE. LTD, a Singapore private limited corporation (“CRH”), additional consideration if production on the Lucky Shot Property meets two separate milestone payment thresholds. If the first threshold of (1) an aggregate “mineral resource” equal to 500,000 ounces of gold or (2) production and receipt by the Company of an aggregate of 30,000 ounces of gold (including any silver

based on a 1:65 gold to silver ratio) is met, then the Company will pay CRH $5 million in cash and $3.75 million in newly issued shares of Contango common stock. If the second threshold of (1) an aggregate “mineral resource” equal to 1,000,000 ounces of gold or (2) production and receipt by the Company of an aggregate of 60,000 ounces of gold (including any silver based on a 1:65 gold to silver ratio) is met, then the Company will pay CRH $5 million in cash and $5 million in newly issued shares of Contango common stock. If payable, the additional share consideration will be issued based on the 30-day trading price. As of December 31, 2025 and 2024, the Company has recognized contingent consideration payable of $2,757,952 and $1,100,480, respectively, associated with the additional share consideration.

Royal Gold Royalties. Royal Gold currently holds a 3% overriding royalty on the Tetlin Lease and certain state mining claims. Royal Gold also holds a 28% net smelter returns silver royalty on all silver produced from a defined area within the Tetlin Lease. Pursuant to the CORE Purchase Agreement, the Company received a prepayment of $1,200,000 for its direct share of silver royalty payments from KG Mining. If the aggregate amount of silver royalty payments exceeds $1,200,000, then beginning with the following calendar quarter such point, the Company shall receive within 45 days after the last day of each such calendar quarter, an amount equal to the product of (i) the amount of the silver royalty earned by the Company pursuant to the Omnibus Royalty Agreement from and after the point at which the silver royalty became greater than $1,200,000 and (ii) CORE Alaska's weighted average interest in the Company during such calendar quarter. The Peak Gold JV commenced production in July 2024 and therefore the Company has started to drawdown the $1,200,000 prepayment into income. The Company has recognized $584,589 in interest and other income for the fiscal year ended December 31, 2025.

CIRI Lease Agreement. JT Mining Inc. entered into a lease agreement effective May 17, 2019 with CIRI and shall pay the sum of $150,000 on the fifth through ninth anniversaries of the effective date, provided that JT Mining Inc.'s obligations to make such payments shall terminate on the commencement of Commercial Production as defined under the agreement. A Commercial Production decision has not been made to date.

CIRI Exploration Agreement. JT Mining Inc. entered into an exploration agreement effective July 1, 2023 with CIRI and on each anniversary of the effective date thereafter during the 4 year term shall pay to CIRI an amount equal to $25,000 as consideration for grant of the rights under the agreement and for the purpose of covering CIRI's administrative costs associated with exploration activities.

Mining Lease and Option to Purchase Agreement Amanita Project. Avidian Alaska entered into a 15 year lease agreement with an effective date of July 18, 2015 with Tanya Stolz. Avidian Alaska shall pay minimum annual lease payments as outlined under the schedule in section 4.1 of the agreement. Avidian Alaska's obligation for July 18, 2025 is $100,000 and will increase by $10,000 per year, with a final payment on July 18, 2030 for $130,000. The minimum payments will be credited against Avidian Alaska's royalty payment obligations under the agreement and the Company is currently in good standing.

Employment Agreements. Mike Clark serves as the Company’s Chief Financial Officer and Secretary and is responsible for performing the functions of the Company’s principal financial officer. Pursuant to his employment agreement (the "CFO Employment Agreement"), Mr. Clark receives a base salary of $400,000 per annum and is entitled to receive short-term incentive plan and long-term incentive plan bonuses and awards that can be paid in the form of a combination of cash, restricted stock and options, which will be set forth in plans and agreements adopted, or to be adopted, by the Board.

He is also entitled to enhanced severance benefits if he terminates his employment within 30 days following a change of control (24 months of base salary and bonus amounts). Any payment of severance benefits to him under the CFO Employment Agreement is conditioned on his timely agreement to, and non-revocation of, a full and final release of legal claims in favor of the Company.

Pursuant to his employment agreement (the “CEO Employment Agreement”), Mr. Van Nieuwenhuyse receives a base salary of $600,000 per annum and is entitled to receive short-term incentive plan and long-term incentive plan bonuses and awards that can be paid in the form of a combination of cash, restricted stock and options, which will be set forth in plans and agreements adopted, or to be adopted, by the Board.

Any payment of severance benefits to him under the CEO Employment Agreement is conditioned on his timely agreement to, and non-revocation of, a full and final release of legal claims in favor of the Company.

Short Term Incentive Plan. The Compensation Committee of the Company's board of directors (the “Compensation Committee”) adopted a Short-Term Incentive Plan (the “STIP”) for the benefit of its executive officers. Pursuant to the terms of the STIP, the Compensation Committee establishes performance goals at the beginning of each year and then at the end of the year will evaluate the extent to which, if any, the officers meet such goals. The STIP provides for a payout ranging between 0% and 150% of an officer’s annual base salary, depending on what performance rating is achieved. Amounts due under the STIP can be partially settled in the form of restricted stock, subject to the terms of the 2023 Plan and discretion of the Compensation Committee.

Committee for Safe Communities Complaint. On October 20, 2023, the Committee for Safe Communities ("CSC"), an Alaskan non-profit corporation inclusive of certain vacation home owners along the Manh Choh ore haul route, formed for the purpose of opposing the Manh Choh project, filed suit in the Superior Court in Fairbanks, Alaska against the State of Alaska Department of Transportation and Public Facilities ("DOT"). The Complaint sought injunctive relief against the DOT with respect to its oversight of the Peak Gold JV's ore haul plan. On May 9, 2025, and at CSC’s request, the Court entered an Order of Dismissal Without Prejudice as to CSC’s one remaining claim, vacated the trial date and closed the case.

Village of Dot Lake Complaint. On July 1, 2024, the Village of Dot Lake, a federally recognized Indian Tribe, located approximately 50 miles from the Manh Choh mine on the ore haul route along the Alaska Highway (“Dot Lake”), filed a Complaint in the U.S. District Court for the District of Alaska against U.S. Army Corps of Engineers (the “Corps”) and Lt. General Scott A. Spellmon, in his official capacity as Chief of Engineers and Commanding General of the Corps. The Complaint sought declaratory and injunctive relief based on the Corps’ alleged failure to consult with Dot Lake and to undertake an adequate environmental review with respect to the Corps’ issuance in September 2022 of a wetlands disturbance permit in connection with the overall permitting of the Manh Choh mine as to approximately five acres of wetlands located on Tetlin Village land. The Peak Gold JV was not named as a defendant in the Complaint, but sought and was granted the right to intervene in the action, and joined the partial motion to dismiss the lawsuit that the Corps filed on August 23, 2024. On September 29, 2025, the Court entered an Order dismissing the action with prejudice based on the Stipulated Dismissal of Action filed by the parties and the Court closed the case.

Cook Inletkeeper, Chickaloon Village Traditional Counsel, Center for Biological Diversity. On September 10, 2024, the Corps issued to Johnson Tract Mining Inc, (a wholly owned subsidiary of the Company) a permit under Section 404 of the Clean Water Act to construct an access road and improve an existing air strip on the south parcel of the Johnson Tract project. On May 20, 2025, Cook Inletkeeper, Chickaloon Village Traditional Council, Center for Biological Diversity, and an individual plaintiff filed suit in the United States District Court for the District of Alaska against the Corps and related officials, challenging the Corps’ issuance of the Section 404 permit. The plaintiffs seek to vacate the section 404 permit issued and halt mineral exploration on the lands. The complaint alleges that the Corps Environmental Assessment for the Section 404 permit failed to adequately analyze the potential for acid rock drainage and contaminants leaching into the Johnson River and Cook Inlet and the harmful effects of the project on beluga whales at the Cook Inlet. In July 2025, the Company filed a motion to intervene as a defendant in the lawsuit to protect its legal rights under the Section 404 permit, its significant investment in the Johnson Tract, and its mineral exploration lease with CIRI. The Alaska District Court has not issued any rulings or relief and the permit in question is still active and in good standing. We believe unfavorable outcome to us is not probable.

Dolly Varden acquisition. Dolly Varden Silver Corporation (“Dolly Varden”) was amalgamated under the Business Corporations Act (British Columbia) on January 30, 2012. Dolly Varden’s primary activity is the acquisition and exploration of mineral properties in Canada.

Dolly Varden is a mineral exploration company focused on exploration and advancing its 100% owned Kitsault Valley project (the “Kitsault Valley Project”), which includes the Dolly Varden property and the Homestake Ridge property located in the Golden Triangle of British Columbia, Canada, 25 kilometers (“km”) by road to tide water. The 163-square km Kitsault Valley Project hosts the high-grade silver and gold resources of Dolly Varden and Homestake Ridge along with the past-producing Dolly Varden and Torbrit silver mines.

In addition to the Kitsault Valley Project, Dolly Varden has consolidated a land package of six other properties in the same region as the Kitsault Valley Project. These six properties have historically been explored for gold, copper, silver, lead and zinc. Including the Kitsault Valley Project and the recent acquisitions, Dolly Varden now holds a combined area of 100,000 hectares within the region.

On December 8, 2025, Contango and Dolly Varden entered into the Arrangement Agreement in respect of the Arrangement. Under the terms of the Arrangement Agreement, Contango will acquire all of the issued and outstanding Dolly Varden Shares at the Exchange Ratio. The estimated fair value of the shares to be issued based on information available as of December 8, 2025 is $397.5 million.

Immediately prior to Closing, all Dolly Varden RSUs will vest and be settled for Dolly Varden Shares. Pursuant to the Arrangement, all outstanding Dolly Varden Options will be exchanged for stock options to acquire Contango Shares, adjusted to reflect the Exchange Ratio. Eligible Canadian stockholders of Dolly Varden will be able to elect to receive exchangeable

shares in a Canadian subsidiary of Contango, which will be exchangeable into Contango Shares, instead of the Contango Shares to which they would otherwise be entitled.

Upon completion of the Arrangement, existing Contango Stockholders and former Dolly Varden Shareholders will own approximately 50.001% and 49.999% each of the combined company, respectively, using the fully diluted in-the-money treasury-stock-method (based on the number of Dolly Varden and Contango securities outstanding as of the date of the Arrangement Agreement).

The Arrangement will be effected pursuant to a court-approved plan of arrangement under the BCBCA and will require approval by (i) the Court, (ii) 66 2/3% of the votes cast by Dolly Varden Shareholders at a special meeting of Dolly Varden Shareholders expected to be held in the first quarter of 2026, and (iii) the affirmative vote of a majority of the Contango Shares present in person or by proxy at the special meeting of Contango Stockholders, expected to be held in the first quarter of 2026, and entitled to vote thereon.

In addition to the approval of the Court and the Dolly Varden and Contango stockholders, the Arrangement is subject to the receipt of applicable regulatory and exchange approvals (including approval of the NYSE American and TSXV), and the satisfaction of certain other closing conditions customary for a transaction of this nature. Subject to the satisfaction of such conditions, the Arrangement is expected to close in the first quarter of 2026. The Arrangement Agreement includes customary deal protections, including reciprocal fiduciary-out provisions, non-solicitation covenants and the right to match any superior proposals. A reciprocal Termination Fee in the amount of $15 million is payable by either party in certain circumstances as set out in the Arrangement Agreement.

As of December 31, 2025, the Company has accrued and capitalized $2.2 million in connection to transaction costs that are direct and incremental costs to the Arrangement.
