Lahontan Drills 9.9m Grading 2.40 g/t Au and 50.7 g/t Ag in Santa Fe Mine Stockpile

TORONTO, July 23, 2026 (GLOBE NEWSWIRE) -- Lahontan Gold Corp. (TSXV:LG, OTCQB:LGCXF, FSE:Y2F) (the " Company " or " Lahontan ") is pleased to announce the first drill results from its 2026 Sonic core drilling program at the Santa Fe Mine Project. The Sonic drilling campaign is evaluating historic heap leach pads and stockpiles to define gold and silver resources that may be suitable for future reprocessing at substantially lower cost than mining and processing fresh rock. The initial results below are from a historic "low-grade" stockpile located adjacent to Heap Leach Pad two at Santa Fe (see map below). The drilling confirms significant gold and silver mineralization within the stockpile and indicates grades substantially higher than anticipated based on the historic stockpile classification.

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*. All drill holes are vertical, true thickness of the intercepts are approximately 100% of the drilled interval. Numbers may not total precisely due to rounding.

The stockpiled material was mined from the Santa Fe open pit by the previous mine operator, Corona Gold, and was set aside for potential future processing. The stockpile abuts Heap Leach Pad two and is readily accessible. CN-extractable gold assays range from 5% to 87% of the corresponding fire assay values, averaging more than 30%. These results suggest the stockpiled material is readily amenable to conventional heap leach processing. Results from six additional Sonic drill holes completed on the "low-grade" stockpile are expected shortly.

Kimberly Ann, Founder, Chair, CEO, and President of Lahontan Gold Corp commented: “The Sonic drilling campaign at Santa Fe is designed to define and verify the tonnage and grade of material remaining in the four historic heap pads at the mine. Approximately 16 million tonnes of material were processed on the heap leach pads, residual gold and silver contained within these historic heap leach pads represent a potentially valuable source of low-cost future feed. The "low-grade" stockpile adjacent to Heap Leach Pad two has long intrigued our team because it consists of readily accessible mined material that could be potentially crushed and heap leached at relatively low cost. The results from these first drill holes not only confirm the presence of gold and silver but also show that the grade of the stockpile is considerably higher than anticipated. The Sonic drilling program has now concluded, with nearly 100 drill holes completed across the four historic heap leach pads. We look forward to reporting additional results as they become available.”

QA/QC Protocols

Lahontan conducts an industry standard QA/QC program for its core, Sonic, 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. CRMs 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 CRMs 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. CRMs with similar grades are inserted as the initial CRM’s run out. The coarse blank material comprised of commercially available landscape gravel and unaltered Tertiary volcanic rock have an expected gold value of -0.005 g/t.

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 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).
