Western Star Resources Defines Tungsten Anomalies at White Star Project Following Soil Sampling Program

October 1, 2026 — Leads & Copy — Western Star Resources Inc. has announced results from its first systematic soil sampling program at its White Star Tungsten Project in Elko County, Nevada, USA. The survey identified two distinct tungsten-in-soil anomalies and elevated tungsten values in areas where the contact between intrusive and carbonate units is covered.

The program, which included 568 samples across both the Rowland and White Star projects, has now been completed. At the White Star project, 253 soil samples were collected, with the highest value reaching 2,230 parts per million (ppm) of tungsten (W), equivalent to 0.28% tungsten trioxide (WO₃), at sample B206.

Two specific tungsten-in-soil anomalies have been defined: the North Zone and the South Zone. The North Zone features 15 anomalous samples spanning approximately 215 by 240 metres, with a peak value of 156 ppm W at sample B048, developed over the quartz monzonite – tactite contact. The South Zone comprises 5 anomalous samples across approximately 135 by 95 metres, peaking at 2,230 ppm W at sample B206, located south of the historical Mission Cross mine.

Blake Morgan, CEO and President of Western Star, stated that the systematic exploration approach used at White Star, similar to that at Rowland, has successfully identified two significant anomalous zones. Morgan highlighted the northern anomaly as particularly noteworthy due to the absence of recorded historical activity in the area, suggesting the presence of tungsten-bearing rock at or near the surface. This finding aligns with the company's exploration strategy for identifying such targets.

Both of Western Star's Nevada properties now have defined soil anomalies and will proceed together into drill target generation. The soil survey at White Star involved sampling at nominal 50-meter intervals, with all samples analyzed by ALS Global using lithium borate fusion and inductively coupled plasma mass spectrometry for 32 elements, including tungsten.

The North Zone, the larger of the two anomalies, is centered around coordinates 625,178 mE / 4,627,244 mN. Fifteen samples define its footprint, which is elongated west-northwest. The peak value of 156 ppm W was recorded at sample B048. This zone is situated across the contact between Cretaceous quartz monzonite and tactite and calc-silicate hornfels. A rock-chip sample from this area, WS-16-01, previously returned 0.126% WO₃.

The South Zone, centered around 625,482 mE / 4,626,626 mN, is approximately 700 meters south of the North Zone. Five samples define its footprint, elongated east-northeast. The highest value of 2,230 ppm W was found at sample B206. This zone is developed over tactite and calc-silicate hornfels, units known to contain coarse garnet and diopside tactite with local scheelite, and lies along the same geological horizon as the past-producing Mission Cross mine.

Geophysical data indicates the North Zone is near a modeled intrusive body and an interpreted magnetic-high lineament. The South Zone, however, is located outside the modeled intrusive footprint and within an interpreted magnetic-low lineament. Neither White Star zone is situated within the modeled intrusive, unlike zone B at Rowland.

The soil results corroborate that soil geochemistry is elevated in tungsten in areas proximal to known mineralization. Western Star plans to continue using soil geochemistry to identify potential mineralized zones and may conduct infill soil surveys in areas with lower-level anomalies.

The district-wide soil program, encompassing 568 samples across both Nevada properties, has now defined four tungsten-in-soil anomalies: the Rowland Main and Northern Zone B anomalies at Rowland, announced in September 2026, and the North and South Zones at White Star. These results will be compiled with magnetic inversion data and outcrop sampling from the 2026 exploration program.

Future steps include infill sampling at a 25-meter spacing in key target zones, extending sampling to the east where the anomaly remains open, and completing additional soil sampling along the prospective horizon. Drill pad locations will be selected to test the four anomalous zones at depth.

Western Star Resources is a mineral exploration company focused on acquiring, exploring, and advancing mineral properties, with a strategic emphasis on tungsten and critical minerals in the United States. The company is currently advancing a portfolio of past-producing tungsten assets in Nevada and New Mexico, alongside exploration exposure at its Western Star property in British Columbia.
