Western Star Resources Inc. (CSE: WSR) (OTC: WSRIF) (FRA: 4K2) has mobilized its technical team to the Rowland Tungsten Property in Elko County, Nevada, to begin the first phase of its 2026 field exploration program, the company announced on May 21, 2026.
The initial program includes a high-resolution drone magnetic survey, systematic prospecting, sampling of historical waste dumps and workings, and a property-wide soil geochemistry campaign. The objective is to refine the company's understanding of the prospective tungsten-bearing skarn horizons and generate drill-ready targets during the 2026 field season.
Blake Morgan, CEO and President of Western Star Resources, stated, "Our team is now on the ground at Rowland and beginning the first modern exploration program on this past-producing tungsten system. The property has documented historical production, visible historical workings, and a compelling skarn geological setting, but it has never been evaluated using modern drone geophysics and systematic property-wide geochemistry."
The Rowland property has historical tungsten production, including reported high-grade tungsten ore shipments during the 1940s and additional production in the 1950s. Historical production figures are based on previous records and have not yet been independently verified by the company.
The 2026 program focuses on three immediate objectives: mapping the prospective skarn horizon more accurately, evaluating historical workings and waste dumps, and defining property-wide geochemical trends. The drone magnetic survey will help map intrusive geometry and structural trends, while the soil sampling campaign aims to identify tungsten-bearing geochemical trends that may not be obvious from historical mapping alone.
Field crews will use portable XRF screening as a field-screening tool to rapidly identify anomalous tungsten and associated elements. The company cautions that XRF readings are preliminary and not a substitute for certified laboratory assays. Selected samples will be submitted for laboratory analysis.
The geological setting at Rowland is interpreted to host tungsten mineralization associated with skarn/tactite development along contacts between evolved intrusive rocks and carbonate-bearing sedimentary units. Previous disclosure describes scheelite occurring with molybdenite, powellite, pyrite, chalcopyrite, and limonite in a garnet-epidote-quartz-calcite skarn assemblage, with skarn and hornfels zones up to 100 feet wide developed along the intrusive contact.
Western Star expects to receive preliminary processed geophysical products in the coming weeks. The results will be integrated with field mapping, LiDAR interpretation, historical workings, and geochemical data to prioritize targets for follow-up work. The goal is to define priority drill targets during the 2026 field season.
