Western Star Resources Inc. (CSE: WSR) (OTC: WSRIF) has announced the results of a high-resolution UAV magnetic geophysical survey at its White Star Tungsten Project in Elko County, Nevada. This is the first modern geophysical dataset acquired over the property, which previously relied on 1960s data with one-mile line spacing. The survey aimed to refine structural controls on mineralization and identify new prospective targets.
The processed data, including Total Magnetic Intensity (TMI), First Vertical Derivative (1VD), Second Vertical Derivative (2VD), and Analytical Signal (AS), have revealed several key features. The historical Batholith mine sits along a northwest-southeast-trending magnetic lineament within a subtle magnetic low. Importantly, a broad magnetic high in the western part of the property is interpreted as a previously unmapped extension of the intrusive granite (quartz monzonite) believed to be associated with tungsten-bearing skarn mineralization. This intrusive body lies adjacent to mapped carbonate units, creating a newly defined area prospective for contact skarn-hosted tungsten.
Multiple magnetic lineaments cutting across the property are interpreted as fault and fracture zones that may have served as pathways for hydrothermal fluids. These findings, combined with pending rock-chip and soil geochemistry, will guide follow-up exploration and potential drill targeting. CEO Blake Morgan emphasized that the results complete the district-scale magnetic coverage for the consolidated Jarbidge-Charleston area, unlocking new areas of interest where granite-carbonate contacts may host tungsten skarn.
Four target zones have been defined for follow-up. The highest priority is the central Kqm–Pzt contact north of the Batholith Mine, a direct strike extension of known mineralization. A northern Pzt body within the northern Kqm mass, cut by a NW-trending magnetic lineament, represents a documented tungsten-bearing host rock with a fluid pathway structure. The southern limestone corridor hosts multiple small limestone bodies with magnetic features analogous to those at the Batholith Mine. The historical open pit area, though under cover, shows coherent magnetic character suggesting continued contact geology.
The White Star survey was flown to the same specifications as the recent Rowland survey, enabling integration into a single district-scale magnetic dataset. This combined dataset is undergoing inversion and will support integrated targeting across both properties. The geophysics will be integrated with geochemistry to define priority targets and inform future exploration phases.

The data were processed by Warren Hughes at East Coast Consulting using Geosoft Oasis Montaj, with grids generated at a cell size of approximately one-third the flight line spacing.
The scientific and technical information has been reviewed and approved by Jasper Mowatt, MIMMM and MAusIMM, a Qualified Person under NI 43-101. Western Star Resources is focused on revitalizing North America's tungsten supply through past-producing assets in historically important mining districts.
