Drilling conditions affected the completion of several holes during this program.

Hole LC-26-174 was lost before reaching its intended target depth. The hole intersected 0.39 g/t Au over 15.24 m above the intended target zone. Hole LC-26-186 was terminated at a depth of 64.01 m due to ground conditions while drilling through the reported mineralized interval of 1.29 g/t Au over 38.10 m. Other results included 0.40 g/t Au over 44.20 m in LC-26-176, 0.35 g/t Au over 10.67 m in LC-26-177, and 0.66 g/t Au over 28.96 m in LC-26-181. Hole LC-26-178 was abandoned, while LC-26-184 did not return significant gold values.

Geological Interpretation and Exploration
Historical drilling at Lapon Canyon has identified gold mineralization associated with a broad, shallow, iron oxide-altered horizon. The 2026 drilling program has also intersected gold mineralization hosted by intrusive rocks, including monzonite, providing additional information for evaluating the distribution and controls of gold mineralization at the project.

The intrusive-hosted mineralization raises the possibility that parts of the system may be related to a broader intrusive-related gold system, potentially including a monzonite porphyry-style setting. Elevated copper values identified through multi-element geochemical sampling provide an additional exploration vector for evaluating this interpretation. Further geological mapping, geochemical work and drilling will be required to assess the nature, extent and significance of the intrusive-hosted mineralization.

The Company is also evaluating whether higher-grade gold intervals, including those previously reported in hole LC-25-170, are associated with structurally controlled zones within the broader mineralized system. The relationship between these intervals and the surrounding mineralization remains an exploration target.

Drilling at Lapon Canyon has generally been conducted from drill pads spaced approximately 30 to 60 m apart, with individual pads accommodating multiple holes oriented at different azimuths. Historical and recent drilling have been used to interpret the mineralized system as predominantly sub-horizontal to moderately south-dipping, with the potential for more steeply dipping higher-grade zones. The geometry and continuity of these zones remain subject to further drilling and interpretation.

The 2026 program has included infill drilling, testing of potential extensions along strike and down dip, and exploration of deeper geological units. The new results will be incorporated into the ongoing compilation, interpretation and modelling of the project.

Geochemical and Geophysical Exploration
The Company is conducting a preliminary soil geochemical survey at Lapon Canyon. Initial results are reported to show a spatial correlation with gold mineralization intersected by drilling. The results remain preliminary and will be evaluated as additional sampling and analytical data become available.

The Company is also reviewing results from its 2026 airborne geophysical survey at Lapon Canyon, Pikes Peak and Rattlesnake. The integration of geochemical data, geophysical interpretations, geological mapping and drilling results is intended to help identify and prioritize additional exploration targets across the Lapon Gold Project.

Michel David, Walker River's President & CEO states: "We are encouraged by the broad gold-bearing intervals returned from the latest drilling at Lapon Canyon. We are continuing to integrate the drilling results with our geological interpretation, soil geochemistry and airborne geophysical data to refine our understanding of the mineralized system and identify additional exploration targets across the project."

Ongoing Work and Next Steps
Ongoing work at Lapon Canyon includes data compilation, geological interpretation, mineralization modelling, detailed geochemical surveys and follow-up field reconnaissance of targets identified from the airborne geophysical survey.

Drilling during 2026 has focused on infill and exploration objectives, including evaluating potential feeder structures and testing deeper intrusive bodies. Results from previous and the 2026 drill programs, including the subsequent data compilation will be the basis for the completion of an initial NI 43-101 compliant mineral resource on the Project. Further assay results will be released as they become available.

Sampling Methodology, Chain of Custody, Quality Control and Quality Assurance
Reverse-circulation drill samples were collected at the drill rig at 1.5-metre intervals. A representative portion of each sample was collected for geological logging, and samples were submitted to American Assay Laboratories in Sparks, Nevada, for preparation and analysis. The Company's quality control program included the insertion of blanks, certified reference material (CRM) standards and duplicate samples at a combined rate of approximately 12%, comprising four of each control type per 100 samples. All sampling was completed under the supervision of a professional geologist (P.Geo.). One CRM failure was identified in the samples from drill hole LC-26-183. The laboratory reanalysed the failed sample and ten samples on either side of it. The repeat results were reported as satisfactory, and the accepted result was incorporated into the project database. Samples were prepared by crushing to greater than 70% passing 2 mm, splitting a 1,000-g subsample, and pulverizing to greater than 85% passing 75 microns (lab code P-c7J10). Gold was analysed by 50-g fire assay with ICP-OES finish (lab code IO-FAAu50). Samples exceeding the 10-ppm gold overlimit threshold were subject to gravimetric determination using a 30 g sample (lab code G-FAAu).

About the Lapon Gold Project
The Lapon Gold Project comprises 147 unpatented mining claims covering approximately 2,940 acres in the Wassuk Range within Nevada's Walker Lane structural corridor, approximately 60 km southeast of Yerington, Nevada. The project includes the Lapon Canyon claim block, Pikes Peak approximately 4 km to the north, and the Rattlesnake and Range Front claims approximately 3 km to the west and at a lower elevation relative to current drilling at Lapon Canyon. The Lapon Canyon claim block comprises 96 claims and is subject to a US$5 million exploration stream earn-in agreement with Nevada Canyon Gold Corp., as announced on February 3, 2025. The project is accessible by secondary state roads located approximately 25 km from the nearest highway. Electrical transmission infrastructure passes within approximately 3 km of the project area.

The Rattlesnake, Range Front and Pikes Peak claim groups cover approximately 8 km of prospective range-front structural trends interpreted by the Company as potential extensions of the mineralized system identified at Lapon Canyon. These claim groups also contain additional exploration targets and historical workings, including adits, shafts and underground development. Limited modern exploration had been conducted on these claim groups prior to Walker River's acquisition. Historical underground workings at Lapon Canyon comprise approximately 2,000 feet (610 m) developed through three adits. Historical sampling reported in the NI 43-101 technical report by Montgomery and Barr (2004) included high-grade gold assays, including a reported sample grading 20.6 ounces per ton Au from the end of the A Adit. These historical results are not necessarily indicative of mineralization throughout the project and have not been presented as current mineral resource estimates.
