High-grade Tungsten Results Nevada Tungsten Portfolio: Rock-Chip Assays up to 4.02% WO₃ at the Rowland Property and 3.00% WO₃ at the White Star Project

Vancouver, British Columbia – TheNewswire - 28th July 2026 - Western Star Resources Inc. (CSE: WSR) (OTC: WSRIF) (FRA; 42K) (the “Company” or “Western Star”) is pleased to announce certified laboratory assay results from the Company’s inaugural programs at its Rowland Tungsten Property and adjoining White Star Tungsten Project, both located in Elko County, Nevada, USA.

Blake Morgan, the CEO and President of Western Star, stated “Receiving results of this tenor, that exceed twice the reported historical grades mark an exciting development at the Rowland and White Star Properties, and demonstrate the high-grade nature of the system in the district. With the geophysics complete across both properties and the assays now in hand, we are building the integrated Jarbidge–Charleston dataset we need to move confidently into drill target generation.”

Key Highlights:

Peak rock-chip assay of 4.02% WO₃ returned from the Rowland Main workings (sample RO-16-01), with additional standout results of 3.00% WO₃ from the White Star Batholith Mine (WS-16-02), and 3 further samples above 2% WO₃ from Rowland Main Zone (RO-19-15, RO-19-10 and RO-16-02).

Outcrop, float and channel sampling at the Rowland Tungsten Property confirms high-grade tungsten mineralisation across all three previously identified zones of historical workings (Northern Zone A, Northern Zone B, and Rowland Main).

Rowland Main: 18 rock-chip, float and channel samples returned samples including 4.02%, 2.69%, 2.56%, 2.11% and 1.25% WO₃, including reporting up to 110.5 ppm Mo, 6.82g/t Ag, 0.4% Cu, and 2.57% Mn

Northern Zone A: 1 rock-chip sample (RO-15-01) returned 0.23% WO₃, 3.06 g/t Ag and 0.31% Mn, and 41.1 ppm Mo.

Northern Zone B: 3 rock-chip samples in the vicinity of the historical processing infrastructure and shaft returned 0.35% to 1.22% WO₃ (peak sample RO-18-02) with a coincident silver and copper value of up to 10.85 g/t Ag and 0.8% Cu (RO-18-03) and molybdenum up to 119.5 ppm Mo.

Initial rock-chip sampling from the White Star Tungsten Property returned 2 samples grading 0.13% and 3.00% WO₃ (WS-16-02), consistent with the recorded historical production grades from the Batholith/Mission Cross Mine, with a strongly anomalous coincident molybdenum credit of 711 ppm Mo at WS-16-02.

Results will be integrated with the completed UAV magnetic geophysical survey and the pending soil geochemistry to support the Company’s ongoing drill target generation across the consolidated Jarbidge–Charleston tungsten footprint.

The Rowland rock-chip and channel sampling program was designed to test the three zones of extensive historical workings visited during the Company’s Phase 1 field program: Northern Zone A, Northern Zone B, and the Rowland Main workings. Samples were collected across open pits, adits, and outcrops.

Northern Zone A One rock-chip sample was collected from Northern Zone A during the Phase 1 field program (RO-15-01) and returned 0.23% WO₃, 3.06 g/t Ag and 41.1 ppm Mo. The sample confirms tungsten mineralisation in the northernmost of the three zones of historical workings and provides a first-pass geochemical anchor for the follow-up program planned in this area.

Northern Zone B Three rock-chip samples were collected across Northern Zone B, in the vicinity of the historical processing infrastructure and shafts. Results range from 0.35% to 1.22% WO₃...
