Western Star Resources Inc. (CSE: WSR) (OTC: WSRIF) has completed Phase 1 exploration at its 100% owned, past-producing Rowland Tungsten Property in Elko County, Nevada, revealing four discrete zones of extensive historical tungsten-bearing workings, according to a company press release dated May 28, 2026. The findings materially increase the property's known potential, as the company had initially anticipated only a single past-producing zone.
The Phase 1 program included a high-resolution UAV magnetic geophysical survey, focused soil geochemistry, rock-chip sampling, and field checking of historical workings. Samples have been rush-submitted to the laboratory, with assay results expected in the coming weeks. The company confirmed zones designated as Northern Zone A, Northern Zone B, Central Zone, and the original Rowland Zone, all hosted within the same skarn-style geological setting.
Blake Morgan, CEO and President of Western Star, noted that the field crew discovered a previously undocumented central area with processing infrastructure, shafts, and 600 to 700 metres of trenching. "Rowland has come out of Phase 1 looking considerably more prospective than the historical record suggested," Morgan said. "We adjusted the program in real time to focus on what was actually on the ground, and have rush-submitted the first round of rock and soil samples."
Northern Zone B emerged as the most significant historical development identified on the property. Field crews confirmed dilapidated wooden infrastructure consistent with a historical ore chute, along with several decommissioned shafts. The zone was first flagged during a pre-mobilization LiDAR review, which identified surface features consistent with historical workings. The surrounding waste dumps and surface piles at Northern Zone A were substantially larger than historical records indicated, suggesting a meaningful volume of material was mined and processed.
At the Rowland Main zone, field work confirmed multiple additional workings, trenches, and surface disturbances. Material from this zone displayed extensive UV fluorescence consistent with scheelite mineralization, with tungsten content further confirmed by portable XRF (pXRF) screening. The company took channel samples across various lithologies and contacts to characterize distribution and grade.
The UAV magnetic survey, the first modern high-resolution geophysical dataset acquired across the property, is currently being processed, with preliminary results expected imminently. The company's near-term priorities include integrating assay results, finalizing the Phase 2 program, and advancing toward drill targeting and drill permitting.
Jasper Mowatt, a Qualified Person as defined by National Instrument 43-101, has reviewed and approved the scientific and technical information in the release. Western Star Resources continues to focus on cost-effective exploration and property development to increase shareholder value. The company also plans to move on to the White Star property, hoping to replicate the success at Rowland. For more information, refer to the original press release at www.newmediawire.com.
