Western Star Resources Reports High-Resolution UAV Magnetic Survey Results from Rowland Tungsten Property

Vancouver, British Columbia — June 17, 2026 — Leads & Copy — Western Star Resources Inc. (CSE: WSR) (OTC: WSRIF) (FRA : 4K2) has announced preliminary results from a high-resolution UAV magnetic geophysical survey conducted across its Rowland Tungsten Property in Elko County, Nevada. The survey aimed to enhance the understanding of structural controls on mineralization, refine geological interpretations, and prioritize future exploration targets on the property.

The acquired dataset is the first modern, high-resolution geophysical survey completed on the Rowland Tungsten Property. Processed and interpreted data products include Total Magnetic Intensity (TMI), First Vertical Derivative (1VD), Second Vertical Derivative (2VD), and Analytical Signal (AS).

Key findings indicate that several existing target zones align with northeast-southwest trending magnetic lineaments, which are interpreted as potential fault structures and fluid pathways. Historical workings and Phase 1 target areas appear to be spatially associated with a refined interpretation of intrusive-carbonate contacts and prospective skarn horizons. Additionally, a magnetic-high domain and an adjacent magnetic-low domain situated south of the historical Rowland zone present as untested features that may signify extensions of the prospective skarn horizon.

These results are set to be integrated with pending Phase 1 soil geochemistry data to inform the design of a Phase 2 exploration program and refine potential drill targets.

Blake Morgan, CEO and President of Western Star, stated, “The results of the high-resolution magnetic survey represent an important step in building the first modern exploration dataset at Rowland. The survey has highlighted multiple structural features and magnetic domains that appear to be associated with historical workings and interpreted skarn horizons. We look forward to integrating these results with the Phase 1 soil geochemistry, which is expected imminently, as we advance toward Phase 2 exploration and the definition of priority targets for a maiden drilling campaign.”

The Rowland area has historically had limited high-resolution public geophysical coverage. The Company believes this is the first modern UAV magnetic survey completed across the property, which allows for a more detailed interpretation of the structural architecture of the mineralized system compared to existing broad-scale geological maps. The drone magnetic survey provided a cost-effective dataset for improved structural and geological setting interpretation.

Preliminary interpretation of the magnetic data has identified multiple northeast-southwest trending linear features, interpreted as potential fault or fracture zones that may have served as hydrothermal fluid pathways for tungsten-bearing skarn mineralization. Areas of historical activity appear to coincide with interpreted intrusive-carbonate contacts and magnetic lineaments, a relationship considered encouraging for tungsten skarn systems. The survey also suggests the intrusive system might be more extensive than previously recognized, potentially extending the prospective intrusive-carbonate contact zone beyond historical workings.

Furthermore, the magnetic-high and adjacent magnetic-low domains south of the historical Rowland zone are untested geophysical features that will be evaluated in Phase 2 exploration, potentially indicating extensions of the Rowland Main zone or additional prospective skarn horizons.

The next steps involve integrating the geophysics data with Phase 1 assay results, expected in the coming weeks, to define priority drill targets and inform the Phase 2 exploration program.

Comprehensive QA/QC protocols were applied to the magnetic survey data. Data processing and gridding were performed by Warren Hughes at East Coast Consulting using Geosoft Oasis Montaj, with diurnal, lag, and heading bias corrections applied. Filtered derivative products were computed from the corrected TMI data. Maps are presented in the NAD 1984 UTM Zone 11N coordinate system.
