Lahontan Acquires Strategic Claims South of The York Pit, Expanding The Santa Fe Mine Project

Lahontan Gold Corp. (TSXV:LG)(OTCQB:LGCXF)(FSE:Y2F) (the "Company" or "Lahontan") is pleased to announce that the Company signed a binding term sheet (the "Term Sheet") on August 18, 2025 to acquire 27 unpatented lode mineral claims (the "YorkClaims") from Emergent Metals Corp. ("Emergent"),adding approximately 2.1 km² of strategic mineral rights to the Santa Fe Mine Project. The claims adjoin the Santa Fe Mine Project immediately south and southeast of the York open pit and gold mineral resource* (please see map below). Resource modeling completed as part of the recent Preliminary Economic Assessment ("PEA") of the Santa Fe Mine Project* demonstrated that gold-silver mineral resources extended in the direction of the York Claims. The acquisition of the York claims will allow the expansion of the York open pit and potentially, a substantial increase of mineral resources in the York area.

Modeled gold and silver mineral resource blocks are shown in yellow, red and orange; the conceptual pit shells used to constrain the mineral resource estimate* are shown in red. An approximate outline of the newly acquired York Claims is shown in bold red.

Kimberly Ann, Lahontan Gold Corp CEO, Executive Chair, and Founder commented: "Lahontan is very excited to acquire the York Claims that are directly adjacent to the York gold mineral resource*. The newly acquired claims will allow a considerable layback of the York pit during mine planning and in mineral resource estimation. Modeling of gold and silver mineralization at York in the Santa Fe Mine Project PEA was constrained by a pit shell that must honor the property boundary*. With the addition of the York Claims, that pit can be greatly expanded, potentially adding resource ounces plus opening up compelling targets for further gold and silver mineral resource expansion. Coupled with recently completed exploration drilling, the Company continues its path of growing size and scale of the Santa Fe Mine Project and enhancing shareholder value".

Emergent and Lahontan contemplate completing a Definitive Agreement (the "Agreement") within 30 days of signing the Term Sheet. The transaction (the "Transaction") is subject to all necessary approvals, including regulatory approval. Terms of the Transaction include:

• On signing the Term Sheet, Lahontan will pay Emergent's U.S. subsidiary, Golden Arrow Mining Corporation ("GAMC"), a sum of US$10,000.
• On signing the Agreement, Lahontan will issue GAMC a US$50,000 promissory note, with a 1% per month interest rate, and payable within six months of signing the Agreement.
• On signing the Agreement, Lahontan will issue 2,000,000 common shares of Lahontan Gold Corp. to GAMC or its designee.
• On signing of the Agreement, payment of the cash, issuance of the shares, and issuance of the promissory note outlined above, GAMC will facilitate the transfer of the York Claims to Lahontan or its designee, to be completed within 30 days.
• As part of the transfer, Lahontan will grant GAMC a 1% NSR royalty (the "Royalty") on the York Claims. At any time before the third anniversary of the Agreement, Lahontan may purchase the Royalty for US$500,000. After the third and before the seventh anniversary of the Agreement, Lahontan may purchase the Royalty for US$1,000,000. The terms and conditions of the Royalty will be defined in the Agreement.

Regarding scientific data on the York Claims by provided previous claimants, the QP has been unable to verify the information and that the information is not necessarily indicative to the mineralization on the York Claims property that is subject to the disclosure.
