Item 1.01 Entry into a Material Definitive Agreement.

On May 4, 2026, Contango Lucky Shot Alaska, LLC (“LSA”), a wholly-owned subsidiary of Contango Silver & Gold Inc. (“Contango” or the “Company”), entered into a purchase and sale agreement (the “Purchase Agreement”) and executed a promissory note (the “Promissory Note”) with Alaska Hardrock Inc. (“AHI”) to acquire 100% ownership of the Company’s Lucky Shot project, located in the Willow Mining District about 75 miles north of Anchorage, Alaska (“Lucky Shot”). Pursuant to the Purchase Agreement, the Company purchased from AHI the underlying real property, mining claims and mining equipment. The consideration totaled $16,074,000, comprised of the following:

The Company is required to pay interest on the outstanding principal balance of the Promissory Note annually on the anniversary of the Closing Date at a rate of 5%, compounded monthly. Principal repayments of $2,000,000 are due on the second and third anniversaries of the Closing Date, with the remaining principal balance due on the fourth anniversary of the Closing Date, or May 4, 2030. The Promissory Note is secured by real property, mining claims, and other assets acquired by LSA from AHI.

As additional consideration of the Purchase Agreement, AHI assigned its rights as the lessor under the Lucky Shot lease agreement (the “Lease Agreement”), which includes a 2% net smelter returns royalty (the “NSR Royalty”) payable to AHI, to LSA. Post-assignment, LSA will be both the lessor and the lessee under the Lease Agreement. Thus, although the Lease Agreement was not terminated (due to remedies available to AHI in an event of default as defined in the Promissory Note), the 2% NSR Royalty contained in the Lease Agreement was effectively terminated from an economic perspective.

The foregoing description of the Purchase Agreement (which includes the Promissory Note as an exhibit) does not purport to be complete and is qualified in its entirety by reference to the terms of the Purchase Agreement, a copy of which is filed as Exhibit 10.1 hereto and is incorporated herein by reference.

Item 1.02 Termination of a Material Definitive Agreement.

Item 2.03 Creation of a Direct Financial Obligation or an Obligation under an Off-Balance Sheet Arrangement of a Registrant.

To the extent required by Item 2.03 of Form 8-K, the information contained in Item 1.01 of this Current Report on Form 8-K is incorporated by reference herein.

Item 7.01 Regulation FD Disclosure.

On May 5, 2026, the Company issued a press release announcing the completion of and results from the initial phase of the 2025/2026 underground diamond drilling program at the Lucky Shot project. A copy of the press release is furnished as Exhibit 99.1 to this Current Report on Form 8-K.

The information included herein and in Exhibit 99.1 shall not be deemed “filed” for purposes of Section 18 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), or otherwise subject to the liabilities of that section, nor shall it be deemed incorporated by reference in any filing under the Securities Act of 1933, as amended, or the Exchange Act.
