LAHONTAN CLOSES STRATEGIC YORK CLAIMS PURCHASE AT SANTA FE

Lahontan Gold Corp. has completed the purchase of 27 unpatented lode mining claims (the York claims) from Emergent Metals Corp. The York claims are contiguous with the southeast corner of the Santa Fe mine project and provide a compelling opportunity to significantly expand oxide gold and silver mineral resources previously defined at the York deposit. Modelling of drill data during the mineral resource estimation process suggests that gold and silver mineralization likely extends onto the York claims. This targeting concept was in part validated by Lahontan's recent drilling campaign where reverse circulation drill hole YOR25-001R cut 89.9 metres (45.7 to 135.6 m) grading 0.23 gram per tonne gold (please see Lahontan Gold news release dated Sept. 2, 2025). The company is currently planning additional drilling at the York target area for this fall. With the addition of the York claims, the company now owns or controls 415 unpatented lode mining claims, 67 unpatented mill site claims and 24 patented lode mining claims encompassing over 2,832 hectares or 28.3 square kilometres of mineral rights in one of the world's premier gold belts: Nevada's Walker Lane.

Kimberly Ann, Lahontan founder, chair, chief executive officer and president, commented: "Lahontan is excited to have completed the purchase of the York claims. The gold and silver resource expansion potential, combined with the ability to further layback the York pit in potential future mining operations, makes the purchase a strategic acquisition for the company. Lahontan now controls a district-scale land package that, despite prolific past production and the completion of over 1,200 drill holes, remains largely unexplored with multiple targets for resource expansion and new discoveries."

Terms of the purchase include:

• Lahontan has paid Emergent's United States subsidiary, Golden Arrow Mining Corp. (GAMC), a sum of $10,000 (U.S.).
• Lahontan has issued GAMC a $50,000 (U.S.) promissory note, with a 1-per-cent-per-month interest rate, and payable within six months of signing this announcement.
• Lahontan has issued two million common shares of Lahontan Gold to Emergent.
• GAMC will facilitate the transfer of the York claims to Lahontan or its designee, to be completed within 30 days of today's date.
• As part of the transfer, Lahontan has granted GAMC a 1-per-cent NSR royalty on the York claims. At any time before the third anniversary of the agreement, Lahontan may purchase the royalty for $500,000 (U.S.). After the third and before the seventh anniversary of the agreement, Lahontan may purchase the royalty for $1-million (U.S.).
