Western Star Resources Inc. (CSE: WSR) (OTC: WSRIF) (FRA: 4K2) has released results from the first-ever systematic soil sampling program at its White Star Tungsten Project in Elko County, Nevada, USA. The survey defined two discrete tungsten-in-soil anomalies and identified elevated tungsten values in areas where the contact between intrusive and carbonate units is under cover, according to the company's October 1, 2026 announcement.
The 253-sample survey at White Star, part of a larger 568-sample program across both the Rowland and White Star properties, returned a peak value of 2,230 ppm tungsten (0.28% WO3) at sample B206. The two anomalies, designated the North Zone and South Zone, represent new targets for the company as it advances both Nevada properties into drill planning together.
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 North Zone, the larger and better-defined anomaly, spans approximately 215 by 240 metres and peaks at 156 ppm tungsten at sample B048. It is developed over the contact between Cretaceous quartz monzonite and tactite and calc-silicate hornfels. The zone contains rock-chip sample WS-16-01, which previously returned 0.126% WO3. The South Zone covers approximately 135 by 95 metres and peaks at 2,230 ppm tungsten at sample B206. It lies over tactite and calc-silicate hornfels, the same geological horizon that hosts the past-producing Mission Cross mine just to the north.
The soil results also provide strong support that in areas local to outcropping mineralisation, soil geochemistry is elevated in tungsten. The North Zone is near a modelled intrusive body from a three-dimensional magnetic inversion and an interpreted magnetic-high lineament, while the South Zone lies approximately 800 metres outside the modelled intrusive footprint within an interpreted magnetic-low lineament. Neither zone sits within the modelled intrusive, unlike the Northern Zone B at Rowland.
Detailed visual representations of the results are available, including Figure 1: Tungsten-in-soil results across the White Star Tungsten Project, which shows the soil values over geological mapping. Additionally, Figure 2: Rowland-White Star District data compilation presents the four distinct targets identified across the district, combining soil geochemistry, magnetic inversion, and rock chip data.
All soil samples were analysed by ALS Global using lithium borate fusion and inductively coupled plasma mass spectrometry for 32 elements including tungsten. The company maintained rigorous quality assurance and quality control protocols, including field duplicates and certified reference materials.
The identification of these anomalies is significant for Western Star as it advances its tungsten exploration strategy in the United States. Tungsten is a critical mineral used in high-strength alloys, electronics, and defense applications, and domestic sources are increasingly important. The company plans to infill the key target zones at 25-metre spacing, extend sampling to the east where the anomaly is open, complete additional soil sampling along the prospective horizon, and select drill pad locations to test the four anomalous zones at depth. These steps could lead to the definition of drill-ready targets and potentially new tungsten resources in Nevada.
Western Star Resources is a mineral exploration company focused on the acquisition, exploration and advancement of mineral properties, with a growing strategic emphasis on tungsten and critical minerals in the United States. The company is advancing a portfolio of past-producing tungsten assets in Nevada and New Mexico while maintaining additional exploration exposure through its Western Star property in British Columbia.
