Western Star Models Buried Intrusive Bodies Across Nevada Tungsten District

Western Star Resources Inc. (CSE: WSR) (OTC: WSRIF) (FRA: 4K2) has announced the results of a district-scale three-dimensional geophysical inversion across its Rowland and White Star tungsten properties in Elko County, Nevada. The modelling has defined buried and partially exposed intrusive bodies and refined the fault network interpreted to channel mineralising fluid into the tungsten skarn system. Notably, the Company's highest-grade rock chips (4.02% WO3 at Rowland and 3.00% WO3 at White Star) both correspond spatially with the contact between these modelled intrusive rocks and the carbonate host, as previously reported in their July 28, 2026 news release. The modelled intrusive framework extends well beyond the limits of mapped outcrop, opening substantial new search space across both properties.

Blake Morgan, CEO and President, stated, 'This is the result we were hoping for. The inversion has modelled intrusive bodies spatially associated with areas where we sampled high grade tungsten values, and it has mapped the faults that we believe carried the fluid there. That is the tungsten skarn recipe, and we can now see it in three dimensions across the whole district. Better still, the modelled intrusives are more extensive than has been previously mapped, which means the ground that has produced our best rock chips continues into untested areas. Soil geochemistry from Phase 2 is due back shortly and we can use these in our drill hole planning.' The inversion was conducted by Warren Hughes, P.Geo., of East Coast Consulting, and identified approximately 25 kilometres of structure in two dominant orientations, which are interpreted as fluid conduits. The model also resolves geology beneath Quaternary cover, providing exploration vectors into previously hidden ground. Soil geochemistry results are expected shortly and will be integrated to define drill targets.

Additionally, Western Star has satisfied the first performance milestone under the option agreement for the Rowland project, having increased the claim area by approximately 165% and identified four rock-chip samples grading above 2.0% WO3, exceeding the requirements. The Company will issue 500,000 common shares to the vendors. The scientific and technical information has been reviewed by Jasper Mowatt, a Qualified Person. The Company continues to advance its portfolio of past-producing tungsten assets in Nevada and New Mexico, with a focus on critical minerals.
