Lahontan Drills Thick Continuous Gold at Santa Fe: 226M Grading 1.22 Gpt Au and New High-Grade Zone

Lahontan Gold Corp. (TSX.V:LG) (formerly, 1246765 B.C. Ltd.) (the "Company" or "Lahontan") is pleased to announce drill results from four additional core drill holes exploring the Santa Fe pit area of the Company's 19 km2 Santa Fe Project in Nevada's Walker Lane. The four drill holes, totaling 1,549 metres, were completed in late 2021. These drill holes targeted down-dip step outs from known gold and silver mineralization along the Santa Fe fault, extensions of oxide and transition mineralization southeast of the Santa Fe pit, and an easterly trending structure that may tie Slab pit mineralization to the Santa Fe pit area. Highlights include

SF21-006c: This core drill hole intercepted continuous gold and silver mineralization over 226 metres (1.22 gpt Au) and the drill hole bottoms in mineralized rock. Within this intercept, Lahontan has discovered a new high-grade zone (the "Bighorn Zone") with the highest Au assays in project history: up to 26.2 gpt Au and 61.0 gpt Ag (27.01 gpt Au Eq, 245.5 - 246.6m; please see table below). This high-grade zone is separate from the BH Zone and suggests that multiple high-grade feeder zones are present at the Santa Fe Project.
SF21-008c: A step-out drill hole southeast of the Santa Fe pit, has successfully intercepted shallow oxidized gold and silver mineralization (75 metres south of previously reported drill hole SF21-004c). This drill hole demonstrates that additional oxide and transition mineralization is extensive south and southeast of the Santa Fe pit, and underscores the resource potential of this area.
SF21-007c and -009c: These two core drill holes targeted the projected extension of the Calvada fault, an east-west trending structure that may tie together mineralization seen at the Slab-Calvada area with the intensely gold and silver mineralized Santa Fe pit area. SF21-007c intercepted 64 metres grading 0.74 gpt Au Eq (please see table below) including up to 2.24 gpt Au Eq in transitional rocks (360.6 - 362.1m, 1.97 gpt Au and 19.7 gpt Ag). Although -009c appears to have drilled over the main structure, the two holes confirm the potential of the Calvada fault zone between the Santa Fe and Slab pits opening up over 1000 metres of potentially mineralized structure.

Kimberly Ann, CEO, President, Director, and Founder of Lahontan Gold Corp commented: "The discovery of a new high-grade zone northwest of the BH Zone suggests that there are multiple "feeder" structures at the Santa Fe Project, opening up additional high-grade targets along the entire strike length of the Santa Fe fault for hundreds of metres. The ubiquitous gold and silver mineralization seen in drill hole SF21-006c extends well below any previous drilling and is a testament to the strength of the Santa Fe hydrothermal system. Drilling results to date are validating our dual path exploration model at Santa Fe: Identify and expand shallow oxide gold and silver mineralization while simultaneously building the scope and scale of deeper, high-grade potential resources."

The latest drill results emphasize the importance of both structural and stratigraphic controls to precious metal mineralization at Santa Fe. It is now apparent that structural intersections, e.g. the Santa Fe fault and easterly-tending faults and splays like the Calvada fault, help localize high grades along their raking intersections. Lahontan will apply this interpretation to further drilling northwest of SF21-006c (please see map above). The entire drilled interval of Triassic Luning Formation limestone was mineralized in SF21-006c and the hole bottomed in mineralized rock. Gold and silver mineralization occurs over tens of square kilometres at Santa Fe. The combined areal and vertical distribution of mineralization points to a very large system with multiple targets, both under cover and on the surface that remain to be tested.

The grade shell adjacent to the Bighorn high-grade zone is based upon modeling historic drilling. Drill hole SF21-006c has intercepted new gold and silver mineralization in both the hanging-wall (above) and the footwall (below) the grade shell, greatly expanding the resource potential of this part of the Santa Fe Project.

QA/QC Protocols:

Lahontan conducts an industry standard QA/QC program for its core and RC drilling programs. The QA/QC program consisted of the insertion of coarse blanks and Certified Reference Materials (CRM) into the sample stream at random intervals. The targeted rate of insertion was one QA/QC sample for every 16 to 20 samples. Coarse blanks were inserted at a rate of one coarse blank for every 65 samples or approximately 1.5% of the total samples. CRM's were inserted at a rate of one CRM for every 20 samples or approximately 5% of the total samples.

The standards utilized include three gold CRM's and one blank CRM that were purchased from Shea Clark Smith Laboratories (MEG) of Reno, Nevada. Expected gold values are 0.188 gpt, 1.107 gpt, 10.188 gpt, and -0.005 gpt, respectively. The coarse blank material comprised of commercially available landscape gravel with an expected gold value of -0.005 gpt.

As part of the RC drilling QA/QC process, duplicate samples were collected of every 20^th sample interval at the drill rig to evaluate sampling methodology. Samples were collected from the reject splitter on the drill rig cyclone splitter. Samples were collected at each 95- to 100-foot (28.96 - 30.48m) mark and labeled with a "D" suffix on the sample bag. No duplicates were submitted for core.

All drill samples were sent to American Assay Laboratories (AAL) in Sparks, Nevada, USA for analyses. Delivery to the lab was either by a Lahontan Gold employee or by an AAL driver. Analyses for all RC and core samples consisted of Au analysis using 30-gram fire assay with ICP finish, along with a 36-element geochemistry analysis performed on each sample utilizing two acid digestion ICP-AES method. Tellurium analyses were performed on select drill holes utilizing ICP-MS method. Cyanide leach analyses, using a tumble time of 2 hours and analyzed with ICP-AES method, were performed on select drill holes for Au and Ag recovery. AAL inserts their own blanks, standards and conducts duplicate analyses to ensure proper sample preparation and equipment calibration. We have all results reported in grams per tonne (gpt).

Overview

Lahontan Gold (TSXV:LG,OTCQB LGCXF) is advancing a portfolio of 100 percent-controlled 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 and is now 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.

Lahontan Gold drilling exploration rig set up

An updated NI 43-101 Mineral Resource Estimate has been completed, showing an overall 22 percent increase from the 2024 MRE. The project now hosts indicated mineral resources of 31.15 Mt grading 0.99 g/t gold equivalent, totaling 993,000 gold equivalent ounces and inferred mineral resources of 41.60 Mt grading 0.71 g/t gold equivalent, totaling 954,000 gold equivalent ounces. That estimate fed directly into the updated PEA announced in October, which outlines an 11-year mine life and average annual production of about 91,900 gold-equivalent ounces.

The company is now focused on filing the supporting technical report and submitting the final Mine Plan of Operations to the U.S. Bureau of Land Management. Construction permits are expected in 2027.

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 6 percent insider ownership.

Note: Mineral resources are not mineral reserves and do not demonstrate economic viability.

Company Highlights

District-scale Nevada Portfolio: Lahontan Gold is advancing a portfolio of 100 percent-controlled 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.
Flagship Brownfields Development: The Santa Fe Mine is a past-producing open-pit heap leach gold and silver operation that produced approximately 359,202 ounces of gold and 702,067 ounces of silver between 1988 and 1994.

Key Projects

Santa Fe Mine (Flagship Brownfields Asset)

Map of Lahontan Gold project location with neighboring projects and owners

The Santa Fe Mine is Lahontan’s flagship, 100 percent-controlled 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. The company completed an updated Mineral Resource Estimate for the project in August 2026, showing an overall 22 percent increase from the 2024 MRE. The project now hosts indicated mineral resources of 31.15 Mt grading 0.99 g/t gold equivalent totaling 993,000 gold equivalent ounces and inferred mineral resources of 41.60 Mt grading 0.71 g/t gold equivalent totaling 954,000 gold equivalent ounces.

The updated resource estimate also includes an indicated oxide and transitional resource of 15.9 million tonnes grading 0.57 g/t gold, alongside 15.2 million tonnes of indicated sulfide grading 1.24 g/t gold.

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.

An updated PEA for Santa Fe outlined an 11-year mine life and a post-tax NPV of US$820 million at base-case prices of US$3,600/oz gold and US$49/oz silver. The study estimates a 40.1 percent IRR and US$1.32 billion in after-tax life-of-mine net cash flow.

Average annual production is projected at about 91,900 gold-equivalent ounces, increasing to about 112,500 in years four to eleven. Estimated gold cash costs are US$1,909/oz and AISC is US$2,250/oz. Pre-production capital is US$172 million, with a projected payback of 3.7 years. The capital cost estimate in the PEA update includes a 20 percent contingency.

Note: Mineral resources are not mineral reserves and do not demonstrate economic viability.

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 features gold and silver mineralization starting directly at surface and has the potential to host a significant shallow oxide gold and silver resource.

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.
