LAHONTAN COMMENCES DRILLING AT WEST SANTA FE

Toronto Ontario, December 16, 2025 – Lahontan Gold Corp. (TSXV:LG, OTCQB:LGCXF) (the

"Company" or "Lahontan") is pleased to announce that it has commenced drilling at its West Santa Fe

project, located only 13 km from the Company’s Flagship Santa Fe Mine project in Nevada’s prolific

Walker Lane. A Foremost MPD-1500 track-mounted reverse-circulation drill rig and support equipment

has begun Lahontan’s maiden drill campaign at West Santa Fe. The initial focus of the West Santa Fe

drilling program will be “twining” multiple historic drill holes from the 1980’s and in order to validate the

historic drill hole database. Prior operators completed 171 drill holes totaling 13,107 metres at West Santa

Fe between 1980 and 1995. Confirming the validity of this robust database may enable the Company to use

this drill hole data in any future Mineral Resource Estimate (“MRE”) for the project.

Lahontan is also pleased to announce that it has completed its 2025 Phase Two drilling program at the Santa

Fe Mine project. During 2025, the Company completed a total of twenty reverse-circulation drill holes in

the Slab and York Resource areas. The objective of the drilling program was to expand gold and silver

resources at depth below the south end of the Slab pit and to step-out and grow mineral resources in the

York area. All Slab area drill holes, which were up to 194 metres deep, remained in oxidized and

hydrothermally altered rock to their final depth.

Kimberly Ann, Lahontan Executive Chair, President, CEO, and Founder commented: “Lahontan is excited

to begin our maiden drill campaign at West Santa Fe. The historic drill hole data are very encouraging, and

we look forward to drill testing this important gold and silver resource exploration target. At the Santa Fe

Mine project, the twenty drill holes completed this year represent the largest number of drill holes

completed in a single year since the Company began drilling the project in 2021. Since that time, Lahontan

has completed 99 diamond and reverse-circulation drill holes totaling 22,431 metres at Santa Fe. We plan

on updating the Santa Fe Mine MRE in early 2026 utilizing the new drill hole data and then incorporating

the MRE into a Preliminary Economic Assessment of the project in H1 2026.”
