Western Star Resources Reports UAV Geophysics Results at the Rowland Tungsten Property

Executive Summary

• Western Star Resources completed the first modern, high-resolution UAV magnetic geophysical survey across its Rowland Tungsten Property in Elko County, Nevada, to better understand structural controls on mineralization and refine exploration targets.
• The survey identified multiple northeast-southwest trending magnetic lineaments interpreted as fault/fracture zones and hydrothermal fluid pathways, which spatially align with historical workings and prospective intrusive-carbonate contacts and skarn horizons.
• Results will be integrated with pending Phase 1 soil geochemistry to prioritize targets for a Phase 2 exploration program and define a maiden drilling campaign.

Key Details

• Survey Scope & Technology: High-resolution UAV magnetic geophysical survey conducted across the Rowland Tungsten Property, Nevada. First modern dataset acquired for the property.
• Processed Products: Total Magnetic Intensity (TMI), First Vertical Derivative (1VD), Second Vertical Derivative (2VD), and Analytical Signal (AS).
• Structural Interpretations: Multiple NE-SW trending linear features identified, interpreted as possible fault or fracture zones that may have served as pathways for hydrothermal fluids associated with tungsten-bearing skarn mineralization.
• Historical & Geological Alignment: Historical workings and Phase 1 target areas coincide with interpreted intrusive-carbonate contacts and prospective skarn horizons, supporting the model that tungsten skarn systems develop where mineralizing fluids interact with reactive carbonate host rocks adjacent to intrusive bodies.
• Untested Features: A magnetic-high domain and adjacent magnetic-low domain immediately south of the historical Rowland zone identified as untested geophysical features that may represent extensions of the prospective skarn horizon or the Rowland Main zone.
• Next Steps & Integration: Magnetic data will be integrated with Phase 1 soil geochemistry assay results (expected imminently) to define the priority drill target inventory and inform the Phase 2 exploration program.
• QA/QC & Data Processing: Data processed using Geosoft Oasis Montaj by Warren Hughes at East Coast Consulting. Diurnal corrections applied via filtered base station readings. Lag and heading bias corrections applied. Derivative products computed from corrected TMI. Grids generated using minimum curvature method with a cell size of approximately one-third of the flight line spacing. All maps presented in NAD 1984 UTM Zone 11N coordinate system.
• Qualified Person: Technical information reviewed and approved by Jasper Mowatt, MIMMM (Membership No. 0486653) and MAusIMM (Membership No. 3178851), per National Instrument 43-101.

Notable Quotes

• Blake Morgan, CEO and President: “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.”
