Western Star Resources Inc. (CSE: WSR) (OTC: WSRIF) (FRA: 4K2) has released results from a high-resolution UAV magnetic geophysical survey completed at its Rowland Tungsten Property in Elko County, Nevada. The survey represents the first modern, high-resolution geophysical dataset acquired at the property, aimed at improving understanding of structural controls on mineralization and refining geological interpretation.
Processed data products include Total Magnetic Intensity (TMI), First Vertical Derivative (1VD), Second Vertical Derivative (2VD), and Analytical Signal (AS). Preliminary interpretation 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 interpreted 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 will be evaluated in Phase 2 exploration, along with integration of pending Phase 1 soil geochemistry results to define priority drill targets for a maiden drilling campaign.
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 UAV magnetic survey provides a cost-effective dataset that significantly improves interpretation of the structural and geological setting. The survey suggests the mapped intrusive system may be more extensive than previously recognized, potentially extending the prospective intrusive-carbonate contact zone beyond historically worked areas.

Comprehensive QA/QC protocols were applied during data collection. Data processing and gridding were performed using Geosoft Oasis Montaj by Warren Hughes at East Coast Consulting. Diurnal corrections, lag and heading bias corrections were applied, and derivative products were computed from corrected TMI data. Grids were generated using the minimum curvature method with cell size approximately one-third of flight line spacing, presented in NAD 1984 UTM Zone 11N coordinate system.
Jasper Mowatt, MIMMM and MAusIMM, a Qualified Person under NI 43-101, has reviewed and approved the scientific and technical information in this release.
Western Star Resources is an emerging junior mineral exploration company focused on revitalizing North America's tungsten supply, advancing its entry into the U.S. market through acquisition of a past-producing tungsten mine in Nevada.
