Western Star Resources Inc. (CSE: WSR) (OTC: WSRIF) (FRA: 4K2) has released the results of a high-resolution UAV magnetic geophysical survey conducted across its Rowland Tungsten Property in Elko County, Nevada. The survey, the first modern geophysical dataset acquired at the property, aims to improve understanding of structural controls on mineralization and refine exploration targets.
Processing and interpretation of Total Magnetic Intensity (TMI), First Vertical Derivative (1VD), Second Vertical Derivative (2VD), and Analytical Signal (AS) data have revealed multiple northeast-southwest trending magnetic lineaments. These are interpreted as possible fault structures and fluid pathways that may have controlled the emplacement of tungsten-bearing skarn mineralization. Historical workings and Phase 1 target areas appear spatially associated with refined intrusive-carbonate contacts and prospective skarn horizons, according to the company.
A magnetic-high domain and adjacent magnetic-low domain located immediately south of the historical Rowland zone represent untested geophysical features that could indicate extensions of the prospective skarn horizon. CEO Blake Morgan 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.”
The UAV magnetic data, acquired cost-effectively, significantly improves the company’s ability to interpret the structural and geological setting. Preliminary interpretation suggests that the mapped intrusive system may be more extensive than previously recognized, potentially extending the intrusive-carbonate contact zone beyond historically worked areas. This will be evaluated through geological mapping and geochemical follow-up.
Western Star plans to integrate the geophysical results with pending Phase 1 soil geochemistry results, expected imminently, to define priority drill targets and inform the Phase 2 exploration program. The company considers the Rowland property one of America’s most important historic tungsten districts and is positioning itself to re-establish a domestic source of this critical mineral.

Quality assurance and quality control protocols were applied during data collection, and processing was performed using Geosoft Oasis Montaj by Warren Hughes at East Coast Consulting. The qualified person for the technical information is Jasper Mowatt, MIMMM and MAusIMM, as defined by National Instrument 43-101.
