Lahontan Closes Strategic York Claims Purchase at Santa Fe

Thursday, 23 October 2025 – 07:30 AM

TORONTO, ON / ACCESS Newswire / October 23, 2025 / Lahontan Gold Corp. (TSXV:LG) (OTCQB:LGCXF) (FSE:Y2F) (the “Company” or “Lahontan”) is pleased to announce that the Company has completed the purchase (the “Purchase”) of 27 unpatented lode mining claims (the “York claims”) from Emergent Metals Corp (“Emergent”).

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*. Modeling 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 (45.7–135.6 m) grading 0.23 g/t gold (please see Lahontan Gold news release dated September 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 millsite claims, and 24 patented lode mining claims encompassing over 2,832 ha (28.3 km²) of mineral rights in Nevada’s Walker Lane.

“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.”
