Lahontan Gold Corp. (TSX-V:LG) (OTCQB:LGCXF) is s pleased to announce plans to drill test the historic Santa Fe East Waste Rock Storage Facility at its flagship Santa Fe Mine Project in Nevada’s Walker Lane. The planned program will consist of up to 100 reverse-circulation drill holes averaging approximately 35 metres in depth. The Santa Fe East WRSF contains approximately 9.0 million tonnes of waste rock removed from the Santa Fe open pit during historic mining operations between 1988 and 1992.

During historic mining operations, the open-pit mining cut-off grade was approximately 0.55 g/t gold. Consequently, material classified as waste at the time may contain gold and silver mineralization that could potentially be economically recovered through heap leach processing. The planned drill program is designed to evaluate the distribution, tonnage, and precious metal grades of material within the Santa Fe East WRSF and assess its potential suitability for heap leach processing.

Kimberly Ann, Founder, Chair, CEO and President of Lahontan Gold Corp., commented: “Lahontan’s exploration team has completed the design of an RC drill program to evaluate the gold and silver potential of the Santa Fe East WRSF. Similar to the historic heap leach pads at Santa Fe, this material has the potential to provide an additional source of low-cost gold production early in the Santa Fe mine life and enhance the gold and silver production profile outlined in our recently announced Preliminary Economic Assessment *.

“Importantly, the PEA mine production schedule already contemplates moving the Santa Fe East WRSF as part of the stripping required to access the underlying Santa Fe gold and silver resources. Since this material is scheduled to be moved as part of the mining operation, evaluating its potential for heap leach processing represents an opportunity to potentially generate additional value from material that would otherwise be handled as waste. We believe this is an important opportunity to further optimize the Santa Fe Mine development plan and potentially enhance the project’s overall economics.”

About Lahontan Gold Corp.

Lahontan Gold Corp. is a Nevada-focused mine development company advancing a portfolio of four gold and silver projects in mining-friendly Nevada’s prolific Walker Lane. The Company’s primary focus is the restart of its flagship, the 28.3 km² Santa Fe Mine project, with a targeted return to production in 2027.

• Santa Fe Mine historic production: 359,202 ounces of gold and 702,067 ounces of silver, open pit mining with heap-leach processing (1988-1995; Nevada Bureau of Mines).
• Current Resources: The Santa Fe Mine has a NI 43-101 compliant Indicated Mineral Resource of 1,195,000 oz Au Eq (47,532,000 tonnes grading 0.72 g/t Au and 5.55 g/t Ag, together grading 0.78 g/t Au Eq) and an Inferred Mineral Resource of 1,190,000 oz Au Eq (60,605,000 tonnes grading 0.59 g/t Au and 2.40 g/t Ag, together grading 0.61 g/t Au Eq), all pit constrained (Au Eq is inclusive of recovery, please see Santa Fe Project Technical Report and note below*).
• October 2026 PEA Highlights: 11 year mine life averaging 91,900 gold-equivalent ounces (“Au Eq”), increasing to approximately 112,500 Au Eq ounces during Years 4 through 11 of the mine life utilizing open-pit mining and heap leach processing. Post-tax net present value at a 5% discount rate (“NPV⁵”) of US$820.0 million and an internal rate of return (“IRR”) of 40.1%, based on the PEA base-case metal prices of US$3,600/oz gold and US$49/oz silver*. Estimated pre-production capital costs of US$172.0 million, including a US$22.2 million contingency with estimated gold cash costs of US$1,909/oz and all-in sustaining costs (“AISC”) of US$2,250/oz*.
• Objectives 2026:
  • Advancing mine permitting activities with the objective of commencing construction in 2027,
  • Continue drill testing the satellite West Santa Fe project, with a maiden resource estimate targeted in early 2027,
  • Continued exploration drilling at Santa Fe focused on expanding known gold and silver mineralization,
  • Drill test historic heap-leach pads to evaluate residual gold and silver mineralization for potential future reprocessing opportunities.

* Please see the Santa Fe Project Technical Report, Authors: Michael Lindholm C.P.G. and Caleb Cook, P. Eng., Effective Date: October 1, 2026, Report Date: October 4, 2026 and Lahontan Gold press release dated October 14, 2026. The Technical Report is available on the Company’s website and SEDAR+. Mineral resources are reported using a cut-off grade of 0.10 g/t AuEq for oxide and transition resources and 0.30 g/t AuEq for non-oxide resources. AuEq for the purpose of cut-off grade and reporting the Mineral Resources is based on the following assumptions gold price of US$3,250/oz, silver price of US$40.00/oz, and oxide gold recoveries ranging from 60% to 79%, oxide silver recoveries ranging from 0% to 30%, transitional gold recoveries ranging from 28% to 45%, transitional silver recoveries ranging from 0 to 13%, and non-oxide gold and silver recoveries of 68% except for the York deposit where non-oxide recoveries are estimated to be 0%.
