TORONTO, July 22, 2026 (GLOBE NEWSWIRE) -- Lahontan Gold Corp. (TSXV:LG, OTCQB:LGCXF, FSE:Y2F) (the "Company" or "Lahontan") is pleased to announce additional drill results from its 2026 drilling program at the Santa Fe Mine Project. The drill results reported herein include 188 metres of diamond drilling at Calvada Central that was originally designed to collect geotechnical data related to mine permitting but also intercepted significant gold mineralization. Two additional reverse-circulation (“RC”) drill holes, totalling 636 metres, were drilled at the south end of the Slab open pit in order to constrain mineralization against the Calvada Fault. Significant results are summarized below:
- Calvada: Drill hole CAL26-03C, a diamond drill hole originally designed to gather geotechnical data for mine permitting, intersected 30.8 metres (94.8 – 125.6m) grading 0.93 g/t Au Eq oxidenear the base of the current resource pit shell*. This includes a 10.7 metre interval (114.0 -124.7 m) of high-grade material: 2.18 g/t Au Eq. Please see the map, table, and section below.
- South Slab Open Pit: Two RC drill holes, designed to constrain gold mineralization against the Calvada Fault, intersected outcropping oxide gold mineralization: 15.2 metres grading 0.40 g/t Au Eq (CAL26-06R; 0 – 15.2m) and 9.1 metres grading 0.22 g/t Au Eq (0 – 9.1m). Please see the map and table below.
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.
High grade gold mineralization grading 3.25 g/t Au (116.7 – 118.1m) in CAL26-03C: Weakly-moderately silicified and bleached FeOx-rich limestone from the Central portion of the Calvada Deposit, Santa Fe Mine project.
Kimberly Ann, Founder, Chair, CEO and President of Lahontan Gold Corp., commented: “This outstanding drill intercept, which includes some of the highest gold grades drilled to date within the Central Calvada deposit, reinforces the importance of the Calvada resource to the Santa Fe Mine project. Once again, a drill hole originally planned to collect geotechnical data, in support of mine permitting, was carefully designed by our team to also intersect the core of the Central Calvada gold deposit, delivering excellent gold grades. This high-grade oxide gold intercept further strengthens our confidence as we continue advancing the Santa Fe Mine project toward anticipated mine construction in 2027. Additional drill results from both the ongoing RC drilling program and the Sonic drilling program targeting stockpiles and historic heap leach pads are expected shortly.”

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. 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 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).
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.
