Western Star Resources mobilizes field team at Rowland Tungsten, launches drone geophysics

  Vancouver, British Columbia, May 21st, 2026 - TheNewswire – Western Star Resources Inc. (CSE: WSR) (OTC: WSRIF) (FRA: 4K2) (the “Company” or “Western Star”) is pleased to announce that its technical team has mobilized and are on the ground at the Company’s Rowland Tungsten Property, located in Elko County, Nevada, USA, to commence the first phase of its 2026 field exploration program. The initial program will include a high-resolution drone magnetic survey, systematic prospecting, sampling of historical waste dumps and workings, and the launch of a property-wide soil geochemistry campaign designed to refine the Company’s understanding of the prospective tungsten-bearing skarn horizons. Western Star’s objective is to use modern geophysics and geochemistry to better define the structural and geological controls on mineralization at Rowland, with the goal of generating drill-ready targets during the course of the 2026 field season.

Key Highlights: Field crews have mobilized to the Rowland Tungsten Property in Elko County, Nevada, to commence the first modern exploration program on the past-producing tungsten system.  Commencement of a high-resolution drone magnetic survey designed to map intrusive contacts, structural corridors, and potential skarn/tactite zones across the property.  Systematic prospecting of historical workings, waste dumps, pits, trenches, and adits previously identified through LiDAR review and field compilation.  Portable XRF screening to rapidly assess tungsten and associated pathfinder elements in waste dumps and altered material.  Launch of a property-wide soil sampling campaign to define tungsten geochemical trends across the broader land package.  Drone geophysical results expected in the coming weeks, subject to contractor processing and interpretation timelines.  Soil samples to be submitted for certified laboratory analysis, with assay results to be released following review and interpretation.  Program designed to refine the prospective horizon and generate drill targets by the end of the 2026 field season.  Blake Morgan, the CEO and President of Western Star, 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. This program is designed to move Rowland from a historical tungsten occurrence toward a modern, drill-targeted exploration project.his key data will give what we need to generste high priority drill targets really for our maiden 2026 drill program.We will have some news regarding drill permits soon” Click Image To View Full Size Figure 1: Field photograph of drone and magnetometer equipment being deployed at the Rowland Tungsten Property.

Exploration Program The 2026 field program is designed to test and refine Western Star’s geological model for the Rowland Tungsten Property. The property has seen historical tungsten production, including reported high-grade tungsten ore shipments during the 1940s and additional production during the 1950s. Historical production figures are based on previous records and have not yet been independently verified by the Company.

The Company’s current work program will focus on three immediate objectives: Map the prospective skarn horizon more accurately. Existing geological mapping indicates that the property is underlain by limestones, shales, and quartzites intruded by a Cretaceous-aged quartz monzonite stock. Contact metamorphism associated with this intrusive event is interpreted to have formed skarn and hornfels zones, which represent the primary prospective environment for tungsten mineralization.  Evaluate historical workings and waste dumps.

Field crews will inspect, map, photograph, and sample historical workings, including open cuts, pits, trenches, shafts, adits, and waste dumps. Portable XRF will be used as a field-screening tool to rapidly identify anomalous tungsten and associated elements. The Company cautions that portable XRF readings are preliminary in nature and are not a substitute for certified laboratory assays.  Define property-wide geochemical trends.

The planned soil sampling campaign is intended to identify tungsten-bearing geochemical trends that may not be obvious from historical mapping alone. Soil geochemistry can help detect dispersion patterns from mineralized skarn zones, especially where bedrock exposure is limited or where mineralized horizons are obscured by cover.  Click Image To View Full Size Figure 2: Map showing the proposed drone magnetic survey coverage, historical workings at the Rowland Tungsten Property. Geological Setting The Rowland Tungsten Property is located in the Jarbidge mining district of northeastern Nevada.

The project is interpreted to host tungsten mineralization associated with skarn/tactite development along contacts between evolved intrusive rocks and carbonate-bearing sedimentary units. Tungsten skarns are commonly associated with granitic intrusions reacting with carbonate rocks, and scheelite is the dominant tungsten mineral in many tungsten skarn deposits. In this geological setting, hot mineralizing fluids related to the intrusive system can react with limestone and other reactive host rocks, producing calc-silicate skarn minerals and potentially concentrating tungsten as scheelite.

Previous disclosure for the Rowland Property 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 believes the key exploration opportunity at Rowland is that the historical workings demonstrate tungsten mineralization is present, but the broader system has not been systematically evaluated using modern exploration tools. Historical mapping has defined prospective geology, but the orientation, continuity, and extent of the mineralized skarn horizons remain insufficiently understood.

The combination of drone magnetics, prospecting, XRF screening, and soil geochemistry is intended to help the Company identify structural corridors, intrusive contacts, concealed skarn zones, and geochemical anomalies that may represent previously unrecognized zones of prospectivity. Drone Magnetic Survey The drone magnetic survey is designed to provide high-resolution geophysical coverage across the property. The survey will help Western Star refine its understanding of intrusive geometry, structural trends, and potential contacts between intrusive and carbonate-bearing units.

These contacts are important because tungsten skarn systems commonly form where mineralizing fluids associated with granitic intrusions interact with carbonate-rich rocks. The resulting magnetic patterns may help identify concealed structural trends, intrusive apophyses, or altered zones that are not clearly visible at surface. Western Star expects to receive preliminary processed geophysical products in the coming weeks.

Once received, the Company will integrate the results with field mapping, LiDAR interpretation, historical workings, and geochemical data to prioritize targets for follow-up work. Soil Geochemistry and XRF Screening The soil sampling program is intended to test the broader geochemical footprint of the Rowland system. The Company will collect soil samples across the property to evaluate tungsten and associated pathfinder elements that may help define mineralized trends.

In addition, field crews will use portable XRF screening on historical waste dumps and altered rock material to rapidly identify areas of elevated tungsten or associated metals. Material of interest will be prioritized for certified laboratory analysis. The Company expects that soil geochemistry will be particularly useful at Rowland because the prospective skarn horizons may extend beyond the known workings and may not be fully reflected in historical surface mapping.

A property-wide geochemical dataset may help identify blind or underexplored zones for future trenching, mapping, or drilling. Path to Drill Target Generation The results of the drone magnetic survey, field prospecting, XRF screening, and soil sampling program will be integrated into a revised geological model for the Rowland Tungsten Property. Western Star’s goal is to define priority drill targets during the 2026 field season.

The Company will provide further updates as geophysical interpretations and laboratory assay results become available.
