Lahontan Drills High Grade Oxide Gold From The Surface At West Santa Fe: 37m Grading 3.11 G/T Au Eq Including 11m Grading 5.75 G/T Au Eq

Toronto Ontario, February 24, 2026 – Lahontan Gold Corp. (TSXV:LG, OTCQB:LGCXF, FSE:Y2F) (the "Company" or "Lahontan") is pleased to announce the final analytical results from our 2025 maiden drilling program at the Company’s satellite West Santa Fe project, located only 13 km from Lahontan’s flagship asset, the Santa Fe Mine project, in Nevada’s prolific Walker Lane. The assay results are from the final reverse-circulation rotary (“RC”) drill are summarized below:

WSF25-04R: 36.6 metres (0.0 – 36.6m) grading 3.11 g/t Au Eq including 10.7 metres (1.5 – 12.2m) grading 5.75 g/t Au Eq from the surface, all oxide. The drill hole emphasizes the high gold and silver grades associated with the South Zone at West Santa Fe.
Also included in the intercept is a second high grade zone: 12.2m (22.9 – 35.1m) grading 3.67 g/t Au Eq.
Individual intercepts range up to 12.04 g/t Au Eq (1.52m, 27.43 – 28.96m, 4.48 g/t Au, 648 g/t Ag).
The grade and geometry of these intercepts correlate well with adjacent historic drill holes, further validating the historic drill hole database (please see cross section below).

Notes: Au Eq equals Au (g/t) + ((Ag g/t/60)*0.70). Silver grade for calculating Au Eq is adjusted to consider estimated metallurgical recovery reported by Kappes Cassiday (1982). True thickness of the intercepts is estimated to be 75-90% of the drilled interval. Numbers may not total precisely due to rounding.

Historic drilling, coupled with the 2025 Lahontan RC drilling, defines a gold and silver mineralized zone with a surface expression of 500 by 350 metres with a true thickness from 35 to over 60 metres. With oxide mineralization starting at the surface, there is good potential to exploit this system utilizing low-cost open pit mining and heap-leach processing.

Kimberly Ann, Lahontan Executive Chair, President, CEO, and Founder commented: “The robust assay results from WSF25-04R confirm the high-grade core of the South Zone as defined by historic drilling and underground mine workings. We are continuing to model the West Santa Fe system to better understand the geology and geometry of gold and silver mineralization.

The geologic team is also fine-tuning a follow-up RC drilling campaign to commence in Spring. Previous field work, including geologic mapping, rock-chip sampling, and airborne magnetic surveys, confirms that the hydrothermal system at West Santa Fe extends at least 1,000 metres east of the main zone of gold and silver mineralization defined by Lahontan and historic drilling (please Lahontan Gold press release dated June 18, 2024). This possible extension of the main mineralized zone, plus untested down-dip extensions of gold and silver mineralization, will be the key targets of the Spring drilling campaign. West Santa Fe continues to be an exciting new exploration target for the Company, one with excellent potential to add important shallow, oxide gold and silver resource ounces to Lahontan’s mineral resource ledger.”

Cross section through drill hole WSF25-04R, West Santa Fe project, Nevada. The results from this drill hole are very similar to historic drilling, in both the grade of gold mineralization and the geometry of the system. Mineralization remains open down-dip to the north-northwest. Note the outcropping nature of the oxidized gold and silver mineralization.

Photo of RC drill cutting from drill hole WSF25-04R, West Santa Fe project, Nevada. The high-grade gold and silver mineralized zones are characterized by thoroughly oxidized limestone. Silicification accompanied by quartz veining is seen in the highest-grade areas (see inset photo above).

Gold and silver mineralization at West Santa Fe is hosted by Triassic age limestone of the Pamlico Formation. The balance of this rock unit is siliceous volcanic and volcaniclastic rock, a strong chemical contrast to the highly reactive carbonate rock, thus mineralization is strongly controlled by stratigraphy. On a detailed scale, higher gold and silver grades are associated with abundant goethite, hematite, and silver halides such as cerargyrite and embolite. While silicification and quartz veining are important hydrothermal alteration features, abundant calcite veining usually accompanies the mineralized intervals.

Brian J. Maher, Lahontan Vice President – Exploration and Founder commented: “The maiden RC drilling campaign at West Santa Fe has been very successful. The geologic setting and mineralogy observed in outcrop and drill holes help explain the good gold and silver recoveries reported previously (Kappes Cassiday, 1982): Thoroughly oxidized horizons accompanied by silver halides. The next phase of exploration at West Santa Fe will focus on testing the eastern extension of the main mineralized zone and exploring down-dip from the main mineralized zone where folding may duplicate the hydrothermal system to the north. Exciting early success with opportunities to significantly expand the size and volume of the gold and silver mineralized system.”

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 MEG, LLC of Lamoille, Nevada (formerly Shea Clark Smith Laboratories of Reno, Nevada). Expected gold values are 0.188 g/t, 1.107 g/t, 10.188 g/t, and -0.005 g/t, respectively. CRM’s with similar grades are inserted as the initial CRM’s run out. The coarse blank material comprised of commercially available landscape gravel with an expected gold value of -0.005 g/t.

As part of the RC drilling QA/QC process, duplicate samples were collected of every 20th 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 or 50-element 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 (g/t).

LAHONTAN DRILLS MORE SHALLOW OXIDE GOLD AT SLAB: 69m GRADING 0.45 g/t Au Eq INCLUDING 17m GRADING 0.81 g/t Au Eq

Toronto Ontario, January 27, 2026 – Lahontan Gold Corp. (TSXV:LG, OTCQB:LGCXF, FSE:Y2F) (the "Company" or "Lahontan") is pleased to announce new assay results from our 2025 Phase Two drilling program at the Company’s flagship Santa Fe Mine Project located in Nevada’s prolific Walker Lane. Lahontan has received analytical results for two additional reverse-circulation rotary (“RC”) drill holes in the south Slab pit area totaling 396 metres (please see table below). Significant results include:

CAL25-011R: 68.6 metres (45.7 – 114.3m) grading 0.45 g/t Au Eq including 16.8 metres (65.5 – 82.3m) grading 0.81 g/t Au Eq: A shallow, thick, intercept of oxide gold mineralization below the current mineral resource pit shell*, expanding the footprint of oxide gold mineralization, especially when coupled with the results from CAL25-012R (please see plan map of drilling and cross section below).

When the entire drill hole is composited without regard to cutoff grade, it averages 0.23 g/t Au Eq over 213.4 metres (0.21 g/t Au, 1.4 g/t Ag).

CAL25-012R: 41.2 metres (32.0 – 73.2m) grading 0.32 g/t Au Eq correlating with the structurally controlled gold mineralization seen in hole CAL25-011R (above) and extending shallow oxide gold mineralization to the southwest and below of the Mineral Resource Estimate (“MRE”) pit shell*.

Notes: Au Eq equals Au (g/t) + ((Ag g/t/60)*0.70). Silver grade for calculating Au Eq is adjusted to consider historic metallurgical recovery as described in the Santa Fe Project Technical Report*. True thickness of the intercepts is estimated to be 80-100% of the drilled interval. Numbers may not total precisely due to rounding.

Kimberly Ann, Lahontan Executive Chair, President, CEO, and Founder commented: “The assay results from the final two 2025 RC drill holes at Slab continue to extend gold mineralization to the south, west, and at depth from the current MRE pit shell*, enhancing the potential mining economics of the Slab gold and silver resource. Lahontan will integrate these new drill holes into an updated MRE for Slab as well as the entire Santa Fe project. The MRE is expected to be completed in the coming months. With a new MRE, combined with updated metallurgy and escalating metal prices, the Company will also complete an updated Preliminary Economic Assessment (“PEA”) as well. More 2025 drill results will be forthcoming as the analytical lab catches up on a busy 2025 exploration season.”

CAL25-011R and -012R are particularly important as they establish large volumes of gold and silver mineralization below and adjacent to the conceptual pit shell used in the current MRE. When modeled using updated metal prices and this additional drilling, these drill holes have the potential to significantly expand the Slab area MRE and contribute to a positive update to the current PEA. Of equal importance, these new pit shells will be used in our Nevada State and Federal mine permit applications, to be submitted later this year.

The current conceptual MRE pit shell is shown in black, an example of a potential new pit outline is shown in red. Deeper gold mineralization in CAL25-011R associated with the Calvada Fault zone is unconstrained by drilling.

These two RC drill holes also confirm the strong structural control of gold mineralization in this portion of the Slab deposit and emphasize the importance of the east-west striking Calvada fault as a major control of gold mineralization on a district scale. The extensive gold mineralization seen in CAL25-011R demonstrates the strength of the hydrothermal system with large volumes of disseminated gold mineralization adjacent to the controlling fault structures. With the Company’s recently approved Exploration Plan of Operations (“EPOO”), Lahontan can now explore the Calvada Fault between the Slab deposit and the main Santa Fe deposit, an area that has seen virtually no exploration drilling over the last 35 years.

In the plan view map of the south Slab pit area below, the key intercepts in drill holes CAL25-011R and -012R can be seen to extend into areas west of the current MRE conceptual pit shell. Previously reported RC drill hole CAL25-010R, a vertical hole, also intercepted significant gold mineralization (please see Lahontan Gold press release dated January 13, 2026). Similar to the cross section above, the plan map highlights the potential to increase gold and silver resources in the Slab pit area of the Santa Fe Mine project.
