RC Drill Program On The Tomasina Vein Zone Target

VANCOUVER – Western Exploration Inc. reported on Phase 1 reverse circulation (RC) drill program on the Tomasina Vein Zone target. The drill area is approximately 1.0 km west of the Gravel Creek resource and down dip from the Saddle and Wood Gulch resource areas, at the Company’s wholly owned Aura gold-silver project. The Tomasina target is a 2.5 km long structural zone down dip of the Saddle and Wood Gulch NI 43-101 resources and the Hammer Head mineralization. It is projected to intersect the highly favorable Eocene Frost Creek tuff (main host rock at Gravel Creek) at the faulted unconformity with the basement Permian-Mississippian Schoonover Formation.
Western completed nine RC drill holes totaling 3,239 meters across the corridor, confirming widespread alteration and veining – strong indicators of a robust hydrothermal system. These results highlight resource expansion potential for the Aura Project, particularly down dip and along strike from existing NI 43-101 resources.
CEO, Darcy Marud, said, “Western Exploration is encouraged by initial visual results of the 2025 RC program, which tested only about 20% of the total strike length of the Tomasina target. Key areas below Saddle, Wood Gulch and Gravel Creek remaining to be drill tested.
Drilling was paused to allow for assay analysis and to extend permitting to next phase targets in this highly prospective target zone. As the drilling has confirmed the presence of widespread alteration and local quartz and sulphide mineralization, additional drilling will be conducted with core drilling or RC drilling with core tails.
The 2025 drill results support Western’s confidence that the Tomasina target holds resource expansion potential that will complement the growing resource base at Gravel Creek and the Jarbidge discovery 1.0 km to the east.”
