TORONTO, ON / ACCESSWIRE / August 27, 2024 / Lahontan Gold Corp (TSXV:LG)(OTCQB:LGCXF) (the "Company" or "Lahontan") is pleased to announce results from five reverse-circulation rotary ("RC") drill holes from the Company's 2024 Phase One drilling campaign at the Company's 26 km 2 Santa Fe Mine project located in Nevada's prolific Walker Lane gold and silver belt. These drill holes were completed in the Slab and Santa Fe pit areas at the Santa Fe Mine where previous Lahontan drilling had outlined significant shallow oxide domain gold and silver resources (Canadian NI 43-101 compliant) that remained open along strike and down-dip*. The five drill holes reported herein, totaling 1,053 metres, targeted potential extensions to these gold and silver resources and were also designed to confirm and limit pit boundaries for the upcoming updated Mineral Resource Estimate ("MRE") and Preliminary Economic Assessment ("PEA") for the Santa Fe Mine project. Highlights include:
48.8 metres grading 0.44 g/t Au and 7.4 g/t Ag (0.51 g/t Au Eq)of shallow oxide mineralization in drill hole CAL24-007R including 7.6 metres grading 1.08 g/t Au and 8.3 g/t Ag (1.16 g/t Au Eq). This drill hole, and CAL24-009R reported below, intercepted significant widths of oxide gold and silver mineralization approximately 350 metres north of the Slab open pit and almost 100 metres north of the MRE conceptual pit shell, greatly expanding the footprint of gold and silver mineralization at the Slab open pit (please see location map, long section, and table below). These drill holes will be used to update the 2023 MRE, expected in September 2024.
7.6 metres grading 2.06 g/t Au and 18.2 g/t Ag (2.22 g/t Au Eq) in drill hole CAL24-009R including 3.1 metres grading 4.26 g/t Au and 18.2 g/t Ag (4.41 g/t Au Eq) within a 50.4 metre total thickness of gold and silver mineralized rock. This drill hole contains some of the highest gold and silver grades seen at the Slab deposit: 5.22 g/t Au (77.7 -79.2m) and 151 g/t Ag (112.8 - 114.3m). This drill hole, coupled with CAL24-007R, open a large area for resource expansion north and northeast of the Slab Pit (please see map, long section, and Grade Thickness map below).
Kimberly Ann, Lahontan Founder, CEO, President, and Director commented: "These final drill results from the Phase One drill program have produced excellent results, expanding Slab oxide gold and silver mineralization hundreds of metres north of the 2023 MRE* conceptual pit shell. We see a definite trend toward thicker zones of mineralization with up to 50 metre down-hole intercepts. Also, silver grades seem to be increasing along this north-northeast trend. These exciting results point to the tremendous potential of the Santa Fe Mine project; the technical team will continue to define areas for future resource expansion drilling throughout the project area. All the results reported herein, as well as the results from the 2023 drilling campaign, are being integrated into a new MRE block model which will form the basis for mining planning and scheduling in the upcoming PEA."
It should be noted that all the drill holes were drilled at an angle with inclinations ranging from -60 to -80 degrees. Therefore, the depth from the surface to any given intercept is less than the down-hole distance of the intercept, the approximate true thickness of each intercept varies from 80 - 90% of the drilled interval.

Plan view of the Slab pit area, Santa Fe Mine, Nevada. The outline of the MRE conceptual pit is shown in red, which encompass the current Slab pit shown in dashed black. All seven 2024 RC drill holes are shown with heavy black drill hole traces, the line of the long section (in yellow and below) is also shown.
The long section above shows all Au Eq blocks modeled from historic drilling, both within and outside of the current MRE pit shell*. The drill hole coloration in the cross section uses the same grades as the resource blocks, but the value only includes g/t Au rather than Au Eq. For the updated MRE, reinterpretation of the block model will increase grade between the current pit shell (black) and the potential new pit shell (dashed). Mineralization remains open to the north with an apparent trend towards higher gold and silver grades (see Grade X Thickness ("GT") interpretation below).
Plan view of the Slab pit area, Santa Fe Mine, Nevada. Contoured silver grade times interval thickness (Ag g/t * interval thickness in metres) is overlain on Lahontan drill holes. The Lahontan drill hole data base was used for contouring purposes. Grade X Thickness plots for gold and Au Eq display a very similar pattern. Of great importance is the northern extension to Slab gold and silver mineralization: the extension remains open and contains some of the best grades in the Slab resource. Another area of open mineralization lies on the eastern edge of the Slab resource where structures may be hinting at new drill targets. The high-grade silver contours continue under the current Slab pit where, due to limited access, Lahontan has not conducted new drilling. The outline of the MRE conceptual pit is shown in red, which encompass the current Slab pit shown in dashed black. All seven 2024 RC drill holes are shown with heavy black drill hole traces, the line of the long section (in yellow) is also shown.
Notes: Au Eq equals Au (g/t) + ((Ag g/t/75)*0.66). 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 80-90% of the drilled interval. Numbers may not total precisely due to rounding. NSA = No Significant Assays.
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 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).
