Western Star Resources Inc. (CSE: WSR) (OTC: WSRIF) (FRA: 4K2) has announced results from a high-resolution UAV magnetic geophysical survey at its Rowland Tungsten Property in Elko County, Nevada. The survey, the first modern high-resolution geophysical dataset acquired across the property, was designed to improve understanding of structural controls on mineralization and refine geological interpretation to prioritize follow-up exploration targets.
Processed and interpreted products include Total Magnetic Intensity (TMI), First Vertical Derivative (1VD), Second Vertical Derivative (2VD), and Analytical Signal (AS). The survey identified multiple northeast-southwest trending magnetic lineaments, interpreted as possible fault structures and fluid pathways. Historical workings and Phase 1 target areas appear spatially associated with refined interpretations of intrusive-carbonate contacts and prospective skarn horizons.
A magnetic-high domain and adjacent magnetic-low domain immediately south of the historical Rowland zone represent untested features that may indicate extensions of the prospective skarn horizon. These results will be integrated with pending Phase 1 soil geochemistry to support 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 limited high-resolution public geophysical coverage, and no previous operator is known to have completed a modern UAV magnetic survey. As a result, existing geological maps are relatively broad in scale. By completing this drone magnetic survey, Western Star has acquired a cost-effective dataset that significantly improves the ability to interpret the structural and geological setting.
Preliminary interpretation identified multiple northeast-southwest trending linear features across the property, interpreted as possible fault or fracture zones that may have acted as pathways for hydrothermal fluids associated with tungsten-bearing skarn mineralization. Several areas of historical activity appear to coincide with interpreted intrusive-carbonate contacts and magnetic lineaments, which is encouraging because tungsten skarn systems commonly develop where mineralizing fluids interact with reactive carbonate host rocks adjacent to intrusive bodies.
The survey also suggests that the mapped intrusive system may be more extensive than previously recognized. If confirmed, this could indicate that the prospective intrusive-carbonate contact zone extends beyond historically worked areas. The magnetic-high and adjacent magnetic-low domains south of the historical Rowland zone are untested geophysical features that 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 include integrating geophysics with Phase 1 assay results, due in the coming weeks, to define the priority drill target inventory and inform the Phase 2 exploration program.
