Western Star Resources Outlines 2026 Exploration Program for White Star Tungsten Project, Elko County, Nevada

  Vancouver, British Columbia - 26 th May, 2026 – TheNewswire - Western Star Resources Inc. (CSE: WSR) (OTC: WSRIF) (FRA: 4K2) (the “Company” or “Western Star”) is excited to release the plan for the first phase of exploration at the Company’s 100% owned and recently acquired White Star Tungsten Project, still pending final approval from the Canadian Securities Exchange (the “CSE”), a past-producing tungsten-molybdenum skarn property in Elko County, Nevada, USA. The White Star Tungsten Project is a road-accessible project located approximately nine miles by road southwest of Jarbidge, in the Charleston Mining District, adjacent to the Company’s Rowland Tungsten Project in the Jarbidge Mining District. The Company has acted rapidly since acquiring the property to plan and prepare to launch the maiden exploration campaign at the project.

The program is designed to deliver the geophysical and geochemical datasets required to define and rank drill targets across the property and to support the Notice of Intent and drill-permitting process with the relevant authorities in Elko County. Key Highlights: First modern exploration program planned for the White Star Tungsten Project since the Mission Cross Mine was shut down in the 1950s  Property wide surveys to be completed to define signature of the past-producing Mission Cross workings to aid exploration, including;  a property-wide high-resolution UAV magnetometer survey;  a property-wide soil geochemistry campaign;  Historical tungsten production recorded at the Mission Cross Mine of approximately 1,000 tons of ore assaying up to 1.0% WO₃ (USGS Bulletin 105), is believed to be part of a larger system which this exploration program is designed to map out.  White Star sits within the same contact metamorphic tungsten-molybdenum skarn setting as the Company’s adjoining Rowland Tungsten Project, with the two properties together covering more than six kilometres of prospective tungsten-bearing horizons.  Blake Morgan, the CEO and President of Western Star, stated “White Star Property surrounds a documented past producer in a tungsten district that has never been evaluated using modern geophysics or systematic geochemistry. Our plan is straightforward: fly the property with a high-resolution drone magnetic survey and use soil geochemistry to define the true scale of the tungsten system at the property.

This is expected to generate datasets leading to drillable targets. Running this in parallel with Rowland gives shareholders a single, integrated district story across the Jarbidge and Charleston mining districts.” Click Image To View Full Size [ Figure 1: White Star Tungsten Project showing proposed UAV magnetometer survey area, planned soil sampling grid, and historical workings. Property Location and Overview The White Star Tungsten Project is located approximately nine miles by road southwest of the town of Jarbidge, in Elko County, Nevada.

The Project lies within the Charleston Mining District, immediately adjacent to the Jarbidge Mining District which hosts Western Star’s Rowland Tungsten Project. The proximity of the two properties affords the Company significant strategic advantages, including shared road access, consolidated logistics, and the ability to advance both projects under a single district-scale exploration program. This area has been known to have high tungsten potential and the Company believes both properties could belong to a contiguous tungsten-molybdenum skarn complex. 2026 Work Program Overview Since acquiring the White Star Project, the Company has compiled the available historical data from USGS Mineral Resources Data System (MRDS ID 10197459), NBMG Bulletin 65 (1968), NBMG Bulletin 105 (1988), and NBMG Mineral Resources of Elko County, Nevada (1976), and is integrating that compilation with the regional geological framework already developed for the adjoining Rowland Tungsten Project.

The planned 2026 White Star field program is built around generating high-resolution data in order to understand how large the system is that was historically exploited at the Mission Cross Mine. There is strong potential that multiple Mission Cross type tungsten opportunities exist within the claim package. The use of property-wide UAV magnetic survey, a property-wide soil geochemistry campaign, provides a mechanism to rapidly advance our understanding of the property, and produce the structural, geophysical, geochemical, and lithological vectors required to define drill targets across the property.

Geology The White Star Tungsten Project is hosted within a contact metamorphic tungsten-molybdenum skarn system, the same deposit style that hosts mineralization at the Company’s adjoining Rowland Tungsten Project. Regional geology consists of sedimentary rocks of Paleozoic age, intruded by a quartz monzonite stock of Cretaceous age and overlain in places by Tertiary rhyolite flows. Adjacent to the intrusive contact, the Paleozoic limestones have been recrystallized and locally contain tremolite and other skarn minerals, including scheelite, powellite, and molybdenite.

USGS Bulletin 105 reports that, at the Mission Cross Mine, scheelite occurs with molybdenite and powellite in a skarn contained within a large granite outcrop. Historical operators developed open-pit and underground workings on this zone during 1954, with additional underground work reported in 1956. The granite-carbonate contact is interpreted as the primary zone of prospectivity, in the same manner as at Rowland, and Western Star believes that additional skarn-hosted mineralization may exist along strike from, and at depth below, the documented historical workings.   Structural Control and Geophysics Historical mapping across the broader Jarbidge-Charleston area indicates a system of intrusive contacts, faults, and structural corridors that are interpreted to have controlled the distribution of mineralizing fluids during skarn development.

The historical Mission Cross Mine workings appear spatially associated with the margin of the Cretaceous quartz monzonite stock; however, the absence of any modern, high-resolution geophysics has limited interpretation of intrusive geometry, structural trends, and concealed contacts at White Star. To address this, Western Star plans to conduct a high-resolution UAV magnetic survey across the full White Star property, representing the first modern geophysical survey on the project. The survey is designed to refine the Company’s structural interpretation, map intrusive contacts at high resolution, identify additional skarn targets along strike from the historical workings, and test whether the White Star and Rowland workings are connected at depth along a common intrusive contact.

Geochemical Sampling The Company will undertake a systematic property-wide soil sampling campaign across the White Star claim package. 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, and is expected to be particularly useful at White Star because the prospective skarn horizons may extend well beyond the known workings. Permitting and Future Plans The Company is initiating the necessary streams of work to submit a Notice of Intent to the U.S. Forest Service authority in Elko County for the White Star Tungsten Project.

The Company intends to advance permitting in parallel with the 2026 exploration program, with the explicit objective of positioning the project for drill testing of high-priority targets once the geophysical, geochemical, and field datasets have been received, reviewed, and integrated. The Company will provide further updates as field mobilization, geophysical interpretations, and laboratory assay results become available.   Approvals The acquisition of the White Star Tungsten Project remains subject to final approval by the CSE.
