Western Star Resources Inc. (CSE: WSR) (OTC: WSRIF) (FRA: 4K2) has announced results from the first-ever systematic soil sampling at its White Star Tungsten Project in Elko County, Nevada, USA. The survey defined two discrete tungsten-in-soil anomalies and elevated tungsten values in areas where the contact between intrusive and carbonate units is under cover. These results complete a 568-sample program across both the Rowland and White Star properties.
Blake Morgan, CEO and President of Western Star, stated, "Deploying the same systematic approach to exploration at White Star as we did at Rowland has defined two excellent anomalous zones. The northern anomaly is particularly exciting as it's in an area where there has been no recorded historical activity. This geochemistry points to tungsten-bearing rock sitting at or very near surface. That is exactly the kind of target our sequential approach is built to find, and it takes both Nevada properties into drill planning together."
The White Star survey comprised 253 soil samples collected on a nominal 50-metre station spacing. The highest value returned was 2,230 ppm W (0.28% WO3) at sample B206. Two anomalies were defined: the North Zone and the South Zone. The North Zone includes 15 anomalous samples across approximately 215 by 240 metres, peaking at 156 ppm W, developed over the quartz monzonite-tactite contact. The South Zone includes 5 anomalous samples across approximately 135 by 95 metres, peaking at 2,230 ppm W, on ground south of the historical Mission Cross mine.
The North Zone is near a modelled intrusive body resolved by a three-dimensional magnetic inversion completed by East Coast Consulting, and an interpreted magnetic-high lineament. The South Zone lies approximately 800 metres outside the modelled intrusive footprint and within an interpreted magnetic-low lineament. Unlike the Northern Zone B at Rowland, neither zone at White Star sits within the modelled intrusive. The soil results also provide strong support that in areas local to outcropping mineralisation, the soil geochemistry is elevated in tungsten.
Across the district, the soil program comprises 568 soil samples across the two Nevada tungsten properties and has 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.

Next steps include infilling the key target zones at 25-metre spacing, extending to the east where the anomaly is open, completing additional soil sampling along the prospective horizon, and selecting drill pad locations to test the four anomalous zones at depth.

All samples were analysed by ALS Global by lithium borate fusion and inductively coupled plasma mass spectrometry for 32 elements including tungsten. Lithium borate fusion was selected because tungsten is refractory and partial digestions under-report tungsten hosted in scheelite and wolframite. WO3 values are calculated from elemental tungsten (W) results using a conversion factor of 1.2611. Chain-of-custody protocols were maintained throughout, with quality control comprising field duplicates, certified reference materials, blanks and duplicates.

This news matters because it confirms that both of Western Star's Nevada tungsten properties now host defined soil anomalies and will be advanced together into drill target generation. For investors, the identification of a high-grade soil value of 0.28% WO3 and two new anomalies suggests potential for a significant tungsten discovery in a region with past-producing mines. Tungsten is a critical mineral, and domestic U.S. supply is a strategic priority, making these results particularly relevant to the broader critical minerals sector.
