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, refine geological interpretation, and assist with prioritizing exploration targets.
The survey processed Total Magnetic Intensity (TMI), First Vertical Derivative (1VD), Second Vertical Derivative (2VD), and Analytical Signal (AS) products. Several existing target zones correspond to northeast-southwest trending magnetic lineaments, interpreted as possible fault structures and fluid pathways. Historical workings and Phase 1 target areas are spatially associated with refined interpretations of intrusive-carbonate contacts and prospective skarn horizons.
Importantly, 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 areas will be evaluated as part of the company's Phase 2 exploration program.
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 broad in scale and provide limited detail on structural architecture. This survey significantly improves the company's ability to interpret the structural and geological setting of the property.
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 coincide with interpreted intrusive-carbonate contacts and magnetic lineaments, which is 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 beyond historically worked areas.
The results will be integrated with pending Phase 1 soil geochemistry to support the design of a Phase 2 exploration program and refine potential drill targets. The company expects Phase 1 assay results in the coming weeks.
Comprehensive QA/QC protocols were applied during data collection. All magnetic data were quality-checked in the field, and final data processing and gridding were performed using Geosoft Oasis Montaj by Warren Hughes at East Coast Consulting. Diurnal corrections were applied using filtered base station readings, and additional corrections for lag and heading bias were applied. Filtered derivative products were computed from corrected TMI data. Grids were generated using the minimum curvature method with a cell size of approximately one-third of the flight line spacing. Maps are presented in the NAD 1984 UTM Zone 11N coordinate system.
