WALKER BEGINS DRILL PROGRAM AT THE LAPON CANYON GOLD PROJECT

Walker River Resources Corp. has commenced its 2026 reverse circulation (RC) drill program at the Lapon Canyon gold project, located within Nevada's prolific Walker Lane gold trend, approximately 60 kilometres southeast of Yerington, Nev.

The 2026 drill program is designed to advance both resource expansion and exploration objectives through a combination of infill and stepout drilling. A primary focus of the campaign will be testing deeper intrusive-related targets, including prospective monzonitic and porphyritic intrusive phases and associated gold-bearing feeder structures identified during the company's 2025 drill program. An initial 10,000 metres of RC drilling is planned, with the potential to expand the program, subject to drilling progress, permitting and access conditions.

As previously announced on May 27, 2026, the company recently completed a property-wide airborne magnetic and radiometric survey covering the Lapon Canyon project. Interpretation of the geophysical data set is continuing and is expected to enhance the company's understanding of the project's geological and structural framework. The results may assist in refining drill targeting and evaluating the potential for additional mineralized systems at depth. Preliminary observations indicate several geophysical features spatially associated with known zones of gold mineralization and previous positive drill results.

Historically, gold mineralization at Lapon Canyon was interpreted to be largely confined to a broad, shallow, iron oxide-altered horizon. Results from the 2025 drilling program, however, identified intrusion-related gold mineralization associated with monzonitic intrusive rocks, significantly expanding the project's exploration model and highlighting the potential for previously unrecognized mineralized source zones at depth.

The recognition of monzonite-hosted gold mineralization may indicate the presence of a broader intrusive-related mineralizing system, a style of mineralization commonly associated with significant gold deposits in Nevada. This interpretation is further supported by elevated copper values observed in multielement geochemical analyses and by the identification of interpreted structural controls that may represent mineralized feeder zones, including those associated with higher-grade intervals intersected in drill hole LC-25-170.

The company looks forward to providing updates as drilling progresses and as interpretation of the recently completed geophysical survey advances.

Michel David, Walker River's president and chief executive officer, states, "We are very excited to start this year's drill campaign at Lapon, after the outstanding drill results from our 2025 drilling, now along with results from the recently completed geophysical survey."

Other continuing work at Lapon Canyon consists of data compilation, resource modelling, a follow-up geological mapping and sampling program, in conjunction with the recent geophysical survey's identified targets. Results from the previous and 2026 drill programs, including the subsequent data compilation will be the basis for the completion of an initial National Instrument 43-101-compliant mineral resource on the project which is expected to be completed in 2026. In addition, using the above exploration work to identify future drill targets in the deeper-seated intrusive bodies and new resource expansion in the relatively unexplored areas of the property.

About the Lapon gold project

The Lapon gold project consists of 147 unpatented mining claims totaling approximately 2,940 acres, located in the Wassuk Range within Nevada's Walker Lane structural corridor, a regionally significant northwest-trending deformation zone that hosts numerous gold and precious metal deposits. The project comprises the Lapon Canyon claim block, the Pikes Peak claims located approximately four kilometres to the north, and the Rattlesnake and Range Front claims located approximately three kilometres to the west and at approximately 600 metres lower elevation relative to current drilling at Lapon Canyon. The Lapon Canyon portion of the project, consisting of 96 claims, is subject to a $5-million (U.S.) exploration stream earn-in agreement with Nevada Canyon Gold Corp., as announced on Feb. 3, 2025. The Rattlesnake, Range Front and Pikes Peak claim groups cover approximately eight kilometres of prospective range-front structural trends interpreted to represent extensions of the mineralized system identified at Lapon Canyon and define several additional exploration targets. The Rattlesnake and Pikes Peak areas host historical workings, including adits, shafts and underground development, as well as road access throughout portions of the claim blocks. Limited modern exploration has been conducted on these claim groups prior to Walker River's acquisition.

We seek Safe Harbor.
