Western Star Resources Inc. (CSE: WSR) (OTC: WSRIF) (FRA: 4K2) has released the results of a district-scale three-dimensional geophysical inversion across its Rowland and White Star tungsten properties in Elko County, Nevada. The modeling, conducted by Warren Hughes, P.Geo., of East Coast Consulting, defines buried and partially exposed intrusive bodies and refines the fault network believed to channel mineralizing fluids into the tungsten skarn system. The company's highest-grade rock chips—4.02% WO3 at Rowland and 3.00% WO3 at White Star—correspond spatially with the contact between modeled intrusive rocks and the carbonate host, and adjacent to interpreted structures. This relationship validates the exploration model and opens substantial new search space, as the modeled intrusive framework extends well beyond the limits of mapped outcrop.
The tungsten skarn model requires three elements: an intrusion to drive the system, reactive carbonate rock to host replacement, and structures to focus fluid flow. The inversion has mapped these components in three dimensions across the district, providing a comprehensive framework for future exploration. Approximately 25 kilometers of structure have been interpreted in two dominant orientations—northeast-southwest and northwest-southeast—which are interpreted as the fluid conduits that fed the skarn. This represents the first structural framework mapped at property scale in the district, offering a clear vector for drilling.
The modeled magnetic domains closely correspond with the geological mapping by Coats (1964), adding depth and continuity to that work. Importantly, the inversion resolves geology beneath the extensive Quaternary cover on the eastern flank of the district, providing an exploration vector into ground that cannot be mapped or sampled at surface. This is a significant advantage, as it allows the company to identify targets in areas previously inaccessible to traditional surface exploration.
Blake Morgan, CEO and President of Western Star, 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.”
The company also announced that it has satisfied the first performance milestone under the option agreement for the Rowland tungsten project. The milestone required increasing the total project claim area by at least 30% and identifying at least three rock-chip samples grading above 2.0% WO3. Both conditions were met: the claim package was expanded from approximately 84 hectares to 221 hectares, an increase of about 165%, and four samples returned grades above 2.0% WO3, including 4.02%, 2.69%, 2.56%, and 2.11%. As a result, the company will issue 500,000 common shares to the vendors, valued at the 10-day volume-weighted average price preceding the verification date, subject to CSE policies.
The results of the inversion will be integrated with soil geochemistry from the Phase 2 program, which is expected shortly. This integration will build a single targeting model for the district, followed by field mapping and sampling to refine the geological model. The resulting targets will be ranked to support the drill program and the permitting process now underway.
The scientific and technical information in this release has been reviewed and approved by Jasper Mowatt, MIMMM, MAusIMM, a consultant to the company and a Qualified Person under NI 43-101. The UAV magnetic survey was conducted by AJ Mining LLC using a DJI Matrice M300 platform carrying a GSMP-35U v8.0 potassium vapour magnetometer. Data processing and inversion were completed by Warren Hughes using Geosoft Oasis Montaj and the MAG3D algorithm.
These developments position Western Star to advance its tungsten assets with a clear, data-driven exploration strategy. The identification of extensive buried intrusives and structural conduits enhances the potential for discovering economic tungsten mineralization, aligning with the growing demand for critical minerals in the United States.
