Lahontan Gold Corp. (TSX.V:LG)(OTCQB:LGCXF) (the "Company" or "Lahontan") is pleased to announce the maiden Mineral Resource Estimate ("MRE") for its flagship Santa Fe Mine, a past-producing open pit, heap leach gold and silver mine located in Mineral County, Nevada. The MRE for Santa Fe is based upon 1,275 drill holes totaling 125,435 metres, including 50 drill holes totaling 13,118 metres drilled by Lahontan since 2021.
Highlights of the MRE include:
- Project-wide pit constrained Indicated Mineral Resources of 1,112,000 contained gold equivalent ("Au Eq") ounces and Inferred Mineral Resources of 544,000 contained Au Eq ounces (assumptions for Au Eq are described in the Notes to Tables 1 and 2).
- Project-wide average grade for the Indicated Mineral Resource is 1.14 g/t Au Eq; the average grade of the Project-wide Inferred Mineral Resource is 1.00 g/t Au Eq.
- Indicated Oxide Resources total 21.6 Mt grading 1.03 g/t Au Eq for 712,000 Au Eq ounces and Inferred Oxide Resources total 11.1 Mt grading 0.73 g/t Au Eq for 262,000 Au Eq ounces.
- The conceptual pit shells returned preliminary strip ratios (waste:ore) of 3.6:1 at the Santa Fe deposit and 2.3:1 at the Slab-Calvada-York Complex. Within both conceptual pits, gold and silver deposits crop out at the surface providing opportunities for rapid, low-cost mining operations.
- The MRE block model shows that gold and silver mineralization extends well beyond the conceptual pit shells, generating high-quality targets for additional drilling and resource growth.
Kimberly Ann, Founder, CEO, and President of Lahontan Gold Corp commented: "Lahontan is thrilled with the results of this MRE for the Santa Fe Mine, validating our business concept focusing on brownfield exploration and development opportunities. The MRE demonstrates the presence of a large, readily exploitable, oxide gold resource and importantly, higher-grade non-oxide gold resources. Shallow, good grade oxide gold mineralization in the high-wall of the Santa Fe pit and outcropping oxide resources in Slab-Calvada-York complex, give the Company a clear option for rapid mine development at a significant production rate. We intend to take advantage of the technical and metallurgical data generated over six years of historical mining and heap-leach processing to quickly evaluate the economic potential of the oxide portion of the mineral resource. All deposits comprising the Santa Fe Mine remain open for resource expansion and we look forward to continued drilling at Santa Fe as we grow and expand the size and scale of the project".

Notes to Tables 1 and 2:
- Mineral Resources have an effective date of December 7, 2022. The Mineral Resource Estimate for the Santa Fe Mine was prepared by Trevor Rabb, P.Geo., of Equity Exploration Consultants Ltd., an independent Qualified Person as defined by NI 43-101.
- Mineral Resources are not Mineral Reserves and do not have demonstrated economic viability. Inferred Resources are considered too speculative geologically to have economic considerations applied to them that would enable them to be classified as Mineral Reserves. An Inferred Mineral Resource has a lower level of confidence than that applying to an Indicated Mineral Resource and must not be converted to a Mineral Reserve. It is reasonably expected that most of the Inferred Mineral Resources could be upgraded to Indicated Mineral Resources with continued exploration.
- Resources are reported in accordance with NI43-101 Standards of Disclosure for Mineral Projects (BCSC, 2016) and the CIM Definition Standards for Mineral Resources and Mineral Reserves (CIM, 2014).
- Mineral Resources were estimated for gold, silver, and gold equivalent (Au Eq) using a combination of ordinary kriging and inverse distance cubed within grade shell domains.
- Mineral resources are reported using a cut-off grade of 0.25 g/t Au Eq for oxide resources and 0.60 g/t Au Eq for non-oxide resources. Au Eq for the purpose of cut-off grade and reporting the Mineral Resources is based on the following assumptions gold price of US$1,770/oz gold, silver price of US$22.00/oz silver, and oxide gold recoveries ranging from 60% to 77%, oxide silver recoveries ranging from 40% to 55%, and non-oxide gold and silver recoveries of 71%, mining costs for ore and waste of US$2.20/t, crushing cost of US$2.71/t, processing cost (oxide) US$6.80/t, processing cost (non-oxide) US$25/t.
- An optimized open-pit shell was used to constrain the Mineral Resource and was generated using Lerchs-Grossman algorithm utilizing the following parameters: gold price of US$1,770/oz gold, silver price of US$22/oz silver, gold selling costs of US$56/oz gold, and silver selling costs of US$3/oz silver. Mining costs for ore and waste of US$2.20/t, crushing cost of US$2.71/t, processing cost (oxide) US$6.80/t, processing cost (non-oxide) US$25/t, G&A cost US$3.99/t. Royalties for the Slab, York and Calvada deposits are 1.25%, and maximum pit slope angles of 50 degrees.
About the Santa Fe Mine:
The Santa Fe Mine is in the Walker Lane mineral belt of western Nevada approximately 50 km from the town of Hawthorne in Mineral County. Nearby operating gold and silver mines include Isabella Pearl (Fortitude Gold) and Borealis (Waterton). The Santa Fe Mine consists of four past-producing open-pits, including the Santa Fe, Slab, Calvada East, and York deposits, within a 19 km2 land package 100% controlled by Lahontan. Gold and silver production occurred between 1988 and 1995 utilizing heap-leach processing that produced a reported 345,000 oz of gold and 711,000 oz of silver (Nevada Bureau of Mines and Geology, 1995). Mineralization occurs as disseminated gold and silver hosted by Triassic age calcareous rocks. Strong stratigraphic and structural controls of mineralization is evident. Considerable exploration potential remains at Santa Fe and the Company intends to continue its aggressive exploration program during 2023.

Oxide Resources:
Oxide resources at the Santa Fe Mine occur at both the Santa Fe deposit and the Slab-Calvada Complex which includes the Slab, Calvada East, York, and Calvada Central deposits. The contained Au Eq oxide ounces for the Slab-Calvada Complex accounts for approximately 19% of the total Indicated Au Eq oxide ounces and 29% of the total Inferred Au Eq oxide ounces. Mineral Resources at the Slab-Calvada Complex are exposed at surface. Oxide resources are open to the north and east of the Slab open pit, along the Calvada Fault, and at the York open pit.
The Santa Fe deposit accounts for 81% of Indicated contained Au Eq oxide ounces, and 71% of Inferred contained AuEq oxide ounces. Oxide Mineral Resources within the Santa Fe deposit are primarily located in the high wall of the Santa Fe open pit. The average grade of the Santa Fe deposit Indicated oxide resource is 1.10 g/t Au Eq, and Inferred oxide resource is 0.77 g/t Au Eq. Oxide resources at the Santa Fe deposit are open to the northeast, south, and southeast.
Santa Fe Non-Oxide Resources:
Non-oxide resources at the Santa Fe Mine are principally located in the Santa Fe deposit below the oxide resources within the resource pit shell. The average grade of the Santa Fe deposit Indicated non-oxide resource is 1.41 g/t Au Eq and the Santa Fe deposit Inferred non-oxide mineral resource is 1.50 g/t Au Eq. Gold is very fine-grained and associated with pyrite. Within the southeastern portion of the Santa Fe deposit, higher-grade gold and silver resources may positively influence project economics. Higher grade gold and silver mineralization extends to the southeast of the Santa Fe deposit, along strike and down-rake, providing excellent exploration opportunities to grow the non-oxide resources at Santa Fe.
Estimation Approach:
Lithology and gold and silver bearing domains were modelled using Leapfrog Geo 2022. These domains are mainly defined by logged jasperoid and limestone-breccia lithologies and continuity of gold grades above 0.1 g/t gold. Ore type domains for oxide, transition and non-oxide were modelled based on ratio of cyanide leachable gold assay values to fire assay gold values in addition to drillhole logs recording abundance of pyrite and oxidation intensity. Transition material represents less than 5% of oxide tonnes and is included in the oxide resource. Domains representing lithology, weathering and mineralization models were assigned to a block model with a block size of 5 m x 5 m x 6 m. Average bulk densities representative of the mineralization and lithology models were assigned to the block model and vary from 2.4 t/m3 to 2.6 t/m3.
Grade capping and outlier restrictions were applied to gold and silver values and interpolation parameters respectively. Top cut values for gold and silver were evaluated for each domain independently prior to compositing to 1.52 m lengths that honor domain boundaries. Estimation was completed using Micromine Origin with Ordinary Kriging (OK) and Inverse Distance cubed (ID3) interpolants. Blocks were classified in accordance with the 2014 CIM Definition Standards. The nominal drillhole spacing for Indicated Mineral Resources is 50 m or less. The nominal drillhole spacing for Inferred Mineral Resources is 100 m or less.
Prospects for eventual economic extraction were evaluated by performing pit optimization using Lerchs-Grossman algorithm with the following parameters: gold price of US$1,770/oz gold, silver price of US$22/oz silver, gold selling costs of US$56/oz gold, and silver selling costs of US$3/oz silver. Mining costs for ore and waste of US$2.20/t, crushing cost of US$2.71/t, processing cost (oxide) US$6.80/t, processing cost (non-oxide) US$25/t, G&A cost US$3.99/t. Royalties for the Slab, York and Calvada deposits are 1.25%. Maximum pit slope of 50 degrees. Processing recoveries range from 60% to 77% for oxide, silver recoveries range from 40% to 55% for oxide and non-oxide gold and silver recoveries are 71%.
Filing of Report:
To support this Santa Fe MRE, a technical report prepared according to National Instrument 43-101 ("Report") will be filed on SEDAR within the next 45 days.

Fast-tracking a past-producing Nevada gold mine toward a 2027 production restart
Fast-tracking a past-producing Nevada gold mine toward a 2027 production restart Keep Reading...
Overview
Lahontan Gold (TSXV:LG,OTCQB LGCXF) is advancing a portfolio of 100 percent-owned gold and silver assets in Nevada’s Walker Lane, led by the Santa Fe Mine, a past-producing open-pit heap leach operation. The company has expanded the mineral resource, completed a NI 43-101 preliminary economic assessment (PEA) and is advancing permitting and technical studies to support the project’s development. Management is driving multiple technical workstreams simultaneously, spanning state and federal permitting, metallurgical optimizations via an on-site laboratory, and engineering studies to support its upcoming production restart.
The company is heading into a back-loaded sequence of significant corporate catalysts planned throughout 2026. Management is targeting an updated NI 43-101 Mineral Resource Estimate in Q2 2026, which will feed directly into an updated Preliminary Economic Assessment (PEA) in Q3 2026. This updated economic study will specifically outline a pathway to achieve an expanded production profile targeting an eventual 100,000 ounces of gold production per year.
Value creation is supported by aggressive, multi-rig exploration campaigns designed to scale the resource base rapidly. The 2026 campaign deploys a three-pronged approach: a 10,000-metre Reverse Circulation program chasing new exploration targets, a 2,023-metre core drilling program to finalize mine permitting data, and a 1,740-metre sonic program executing 96 drill holes into historic heap leach pads to add low-cost ounces directly to the mine life.
The execution of this corporate strategy is guided by a founder-led management team and an independent board with deep operational histories in the Great Basin. This leadership capability is validated by a corporate share structure that features 41 percent institutional ownership—including resource funds like MERK, EMA (Larry Lepard), APAC, and PALOS—alongside 4 percent insider ownership.
Company Highlights
- District-scale Nevada Portfolio: Lahontan Gold is advancing a portfolio of 100 percent-owned gold and silver projects in Nevada’s Walker Lane, anchored by the Santa Fe Mine and complemented by the West Santa Fe and Moho projects.

Key Projects
Santa Fe Mine (Flagship Brownfields Asset)
The Santa Fe Mine is Lahontan’s flagship, 100 percent-owned gold and silver project located in Nevada’s Walker Lane. Covering a district-scale land package of more than 28 square kilometres, the past-producing open-pit heap leach operation produced 359,202 ounces of gold and 702,067 ounces of silver between 1988 and 1994.
Current resource modeling shows substantial gold oxide mineralization remaining directly within the high-wall and pit bottoms, which feature highly competent wall rock and stable 50-degree pit slopes. With an overall Indicated oxide grade of 0.64 g/t gold, Santa Fe hosts one of the highest operating or development heap-leach oxide grades in the entire state of Nevada.
Recent drilling has successfully demonstrated that the resource base remains open for depth and strike expansion. Deep core drilling beneath the conceptual pit boundaries at the Calvada deposit intercepted 90.8 metres grading 0.44 g/t gold equivalent oxide, confirming significant down-dip expansion potential. Simultaneously, 2026 step-out exploration drilling discovered a brand-new gold zone called West Slab, yielding unconstrained structural intercepts of 35.0 metres grading 0.34 g/t gold equivalent and 61.0 metres grading 0.26 g/t gold equivalent. The mine plan features a conventional cyanide heap-leach setup processing 12,500 tons per day through a three-stage crush and conveyor loading sequence to produce gold-silver doré bars directly on site.
West Santa Fe (Satellite Oxide Asset)
West Santa Fe is a satellite project located just 13 kilometres west of the main Santa Fe Mine infrastructure, encompassing a 19 square kilometre land package. The asset outlines a shallow oxide gold and silver deposit starting directly at the surface, with a conceptual exploration target of 0.5 to 1.0 million ounces. Lahontan holds a 7-year option agreement to acquire 100 percent of the property for a total buyout price of US$1.8M, with total expenditures of US$1.4M over seven years structured to establish its maiden mineral resource estimate.
Recent twin-hole drilling has confirmed the validity of the historical database while delivering exceptional grades. Reverse Circulation hole WSF25-04R hit 36.6 metres grading 3.11 g/t gold equivalent from the surface, including a high-grade zone of 10.7 metres grading 5.75 g/t gold equivalent in completely oxidized material. Metallurgical testing highlights excellent processing characteristics; historic column leach tests showed 70 percent gold and 50 percent silver recoveries, while recent cyanide-extractable assay results outperformed expectations with an average gold recovery of 81 percent and silver recovery of 60 percent. Because the deposit aligns structurally as a look-alike to the main Santa Fe pit, it is being designed as a low-cost, open-pit satellite operation that can feed directly into the flagship processing hub.
Moho Mine (Satellite High-Grade Asset)
The Moho Mine represents a satellite high-grade gold and silver asset within Lahontan’s regional Walker Lane portfolio. Characterized by an extensive multiple-vein system, the historic underground asset features historic mining grades of 25 g/t gold and 300 g/t silver. It provides the company with localized, high-grade exploration targets that run parallel to its primary large-scale gold oxide heap-leach development projects.
