Lahontan Gold Advances Nevada Exploration with Dual Drilling Programs

Lahontan Gold Corp. has launched its first drilling program at the West Santa Fe project in Nevada's Walker Lane, employing a reverse-circulation drill rig to twin historic holes and validate a legacy database. This database comprises 171 drill holes totaling more than 13,000 metres completed between 1980 and 1995, which could support future mineral resource estimates. The company simultaneously completed its 2025 Phase Two drilling program at the nearby Santa Fe Mine project, where twenty reverse-circulation drill holes targeted gold and silver resource expansion at depth and in step-out areas.

This year's campaign represents the largest annual drilling effort at Santa Fe since drilling began in 2021, supporting plans to update the mineral resource estimate and advance a preliminary economic assessment in 2026. The Santa Fe Mine project, covering 26.4 square kilometers, has a history of past production totaling 359,202 ounces of gold and 702,067 ounces of silver between 1988 and 1995 from open pit mines using heap-leach processing. Current resources include a Canadian National Instrument 43-101 compliant Indicated Mineral Resource of 1,539,000 ounces of gold equivalent and an Inferred Mineral Resource of 411,000 ounces of gold equivalent, all pit constrained.

The technical content of the company's disclosure has been reviewed and approved by Michael Lindholm, CPG, Independent Consulting Geologist to Lahontan Gold Corp., who is a Qualified Person as defined in National Instrument 43-101. The company's technical report, titled "Preliminary Economic Assessment, NI 43-101 Technical Report, Santa Fe Project," is available on the company's website and SEDAR+. Mineral resources are reported using specific cut-off grades and assumptions including a gold price of US$1,950 per ounce and silver price of US$23.50 per ounce.

These developments occur within Nevada's mining-friendly jurisdiction, where Lahontan holds four top-tier gold and silver exploration properties through its US subsidiaries.

The dual drilling initiatives represent significant steps toward validating historical data and expanding known resources, which could ultimately support future production decisions. The validation of West Santa Fe's legacy database through modern drilling techniques provides crucial data verification that could transform historical information into compliant resource estimates. Meanwhile, the expanded drilling at Santa Fe Mine aims to increase resource confidence and support economic assessments that could advance the project toward development.

These activities occur against a backdrop of ongoing mineral exploration in Nevada's Walker Lane region, known for its mineral endowment. The company's systematic approach to resource validation and expansion follows established industry standards, with technical oversight ensuring compliance with disclosure requirements. The planned 2026 preliminary economic assessment will provide important insights into the potential economic viability of the Santa Fe Mine project, while West Santa Fe drilling results will determine the project's resource potential.
