                   TORONTO, ON /  ACCESS Newswire / September 2, 2025 / Lahontan Gold Corp. (TSXV:LG)(OTCQB:LGCXF)(FSE:Y2F) (the "Company" or "Lahontan")   is pleased to announce the results from our 2025 Phase One drilling   program at the Company's flagship Santa Fe Mine Project located in   Nevada's prolific Walker Lane. Lahontan completed seven   reverse-circulation rotary ("RC") drill holes totaling 1,210 metres (please see table below). Significant results include:
 
 - York: 89.9 metres (45.7 - 135.6m) grading 0.23 g/t Au (YOR25-001R): A very shallow, thick, intercept of oxide gold mineralization   that greatly expands the footprint of the York gold zone and confirms   the potential to expand the York gold resource along strike and   down-dip, leveraging the upside value of the recently announced York   claim acquisition (please see cross section below).
 
  - York: A second higher grade zone at York:   18.3 metres (141.7 - 160.0m) grading 0.73 g/t Au including 12.2m   grading 1.00 g/t Au (YOR25-002R). This drill hole bottomed in oxidized   gold mineralized rock and is open up and down-dip, and along strike,   defining a second gold trend at York.
 
  - Slab: 39.6 metres (67.1 - 106.7m) grading 0.30 g/t Au immediately below the south end of the Slab open pit   (CAL25-004R). This drill hole defines a second, strataform, oxide gold   horizon that mimics the geometry of the Slab mineral resource defined  by  prior drilling* and confirms a new target for gold resource  expansion.
 
  
         Cross   section through drill hole YOR25-001R. The thick oxide gold intercept   correlates with adjacent drill holes demonstrating excellent continuity   to gold mineralization and the potential to greatly expand the   conceptual pit shell used to constrain the gold mineral resource   estimate at York. Note that the true thickness of the gold intercept is   approximately equal to the drilled interval.
  The 2025 Phase One  RC  drilling program was intended to confirm multiple target concepts in   the York and Slab gold resource areas at the Santa Fe Mine Project.   Based on the very positive results described in more detail below, the   Company is in the process of planning additional drilling at both York   and Slab for later this year.
  York Drilling:  Both RC drill  holes completed at York successfully defined new  extensions to known  oxide gold mineral resources*. As shown above,  YOR25-001R confirmed the  down-dip continuity of shallow oxide gold  mineralization east of the  York open pit along the Columbia Fault. Gold  mineralization in the drill  hole shows excellent correlation with  previous drilling, in both  thickness and gold grade. As noted above,  oxide gold mineralization is  open to the north where the gold zone  appears to become shallower, and  to the south, where mineralization is  unconstrained by drilling.  Importantly, the newly acquired York claims  (please see Lahontan press  release dated August 19, 2025) provide ample  room for further oxide gold  resource expansion, without the constraint  of a claim boundary.
  YOR25-002R  is particularly interesting as  it validates the geologic model for the  York Fault, an important  north-south striking fault that is a key  control for gold  mineralization in the York area (please see map and  section below).  YOR25-002R bottomed in good grade oxide gold  mineralization (1.0 g/t  Au) that may be corelate to the gold zone  defined in YOR25-001R, and is  likely the upper portion of a much thicker  gold zone: another target  for resource expansion drilling in the Fall  (please see section below).  The York Fault gold system remains open  up-dip, down-dip, and along  strike.
  These two drill holes at York  underscore the potential  to greatly expand the York gold resource and  demonstrate the  considerable upside of the York area at Santa Fe,  amplified by the  recently acquired new claims at York.

         Cross   section through drill hole YOR25-002R (see location map for line of   section). Combined with the results from YOR25-001R, the drilling   confirms the potential to expand the York conceptual pit shell as shown   in red. YOR25-002R bottomed in oxide gold mineralization grading 1.0  g/t  Au Eq. This intercept may correlate with the thick zone defined by   YOR25-002R and therefore defines an excellent target for future  resource  expansion drilling (black dashed line).
  Slab Drilling:   Lahontan completed five RC drill holes in the Slab gold resource area   (see map below). All the drill holes cut oxide gold mineralization   (please table below), however the results for drill holes CAL25-003R and   -004R are very encouraging, defining a new, stacked zone of oxide gold   mineralization below the resource defined by previous drilling and the   Slab open pit*.

  CAL25-004R   cut 39.6 metres grading 0.30 g/t Au and 1.2 g/t Ag (0.31 g/t Au Eq,  see  table below), all oxide, and directly below gold mineralization  seen in  the Slab open pit and defined by historic drilling (see section  below),  providing an excellent opportunity to expand the conceptual  pit shell  at Slab. Additional drilling along strike and northwest of  CAL25-004R  (left in section) can add to potential gold resources at  Slab and  improve future project economics.

  The other drill   holes at Slab, CAL25-001R through -003R all hit zones of gold   mineralization and will require additional drilling to refine drill   targets for future resource expansion.
  Kimberly Ann, Lahontan  Gold  Corp CEO, Executive Chair, and Founder commented: "Lahontan is  excited  with the results from Phase One drilling at Santa Fe. In  particular, the  results from the York area, thick, shallow intercepts  of oxide gold  mineralization, highlight the tremendous upside potential  of York,  amplified by the recent expansion of our land package at  York. We are in  the process of designing a Phase Two drilling program  for York and  Slab, to take place in the Fall".
 
         Notes:   Au Eq equals Au (g/t) + ((Ag g/t/83)*0.60). 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.
  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).
