Western Star Resources Inc. (CSE: WSR) (OTC: WSRIF) (FRA: 4K2) has released results from a high-resolution UAV magnetic geophysical survey at its Rowland Tungsten Property in Elko County, Nevada. The survey, designed to improve understanding of structural controls on mineralization and refine geological interpretation, marks the first modern, high-resolution geophysical dataset acquired across the property.
Processed products including Total Magnetic Intensity (TMI), First Vertical Derivative (1VD), Second Vertical Derivative (2VD), and Analytical Signal (AS) revealed several northeast-southwest trending magnetic lineaments, interpreted as possible fault structures and fluid pathways. Historical workings and Phase 1 target areas align with refined interpretations of intrusive-carbonate contacts and prospective skarn horizons. Notably, a magnetic-high domain and adjacent magnetic-low domain south of the historical Rowland zone represent untested features that may indicate extensions of the prospective skarn horizon.
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 had limited high-resolution public geophysical coverage, and no previous operator had completed a modern UAV magnetic survey. Existing geological maps provided limited detail on structural architecture. The drone survey has significantly improved the Company’s ability to interpret the structural and geological setting. Preliminary interpretation identified multiple northeast-southwest trending linear features, likely fault or fracture zones that may have acted as pathways for hydrothermal fluids associated with tungsten-bearing skarn mineralization.
Several areas of historical activity coincide with interpreted intrusive-carbonate contacts and magnetic lineaments, considered encouraging as tungsten skarn systems commonly develop where mineralizing fluids interact with reactive carbonate host rocks adjacent to intrusive bodies. The survey also suggests the mapped intrusive system may be more extensive than previously recognized, potentially extending the prospective intrusive-carbonate contact zone beyond historically worked areas.
Magnetic-high and adjacent magnetic-low domains south of the historical Rowland zone represent two untested geophysical features. These will be evaluated as part of Phase 2 exploration and may represent potential extensions of the Rowland Main zone or additional prospective skarn horizons.

Next steps involve integrating geophysics with Phase 1 assay results, due in the coming weeks, to define priority drill targets and inform the Phase 2 exploration program. QA/QC protocols were applied during data collection, and processing was performed using Geosoft Oasis Montaj by Warren Hughes at East Coast Consulting. Diurnal corrections, lag and heading bias corrections were applied, and filtered derivative products were computed from corrected TMI data. Grids were generated using minimum curvature with a cell size of one-third flight line spacing, presented in NAD 1984 UTM Zone 11N.
