Western Star Announces 0.53% Wo3 In Soil At The Rowland Tungsten Property As Phase 2 Refines Drill Target Zones
VANCOUVER, BRITISH COLUMBIA - September 18, 2026 (NEWMEDIAWIRE) - Western Star Resources Inc. (CSE: WSR) (OTC: WSRIF) (FRA: 4K2) (the “Company” or “Western Star”) is pleased to announce results from the Phase 2 soil geochemical survey at its Rowland Tungsten Property in Elko County, Nevada, USA. The survey has defined two discrete, spatially coherent tungsten-in-soil anomalies, each expanding the zones around historical workings.
Blake Morgan, the CEO and President of Western Star, stated, “These results show the methodical exploration approach is paying off. We have defined two significant soil anomalies over the historical workings and extended the recognised footprint well beyond them. Northern Zone B is the tighter of the two, a compact cluster elongate to the northeast, sitting within the modelled intrusive. Rowland Main is the larger footprint, and its best sample, 0.53% WO3, lies 250 metres from the nearest historical working on ground with no recorded past activity. That is the part that interests us most: the strongest result came from ground nobody has tested.”
Key Highlights:
-
315 soil samples collected across the Rowland Tungsten Property including a highly anomalous value of 4,240 ppm W (0.53% WO3) at sample R079.
-
Two discrete tungsten-in-soil anomalies defined: the Rowland Main anomaly and the Northern Zone B anomaly.
-
Rowland Main anomaly: 18 samples with anomalous values across a footprint of approximately 190 by 630 metres. The highest-grade sample also carries 66.9 ppm Sn, the highest tin value in the survey.
-
Northern Zone B anomaly: 13 anomalous samples across 190 by 190 metres, peaking at 228 ppm W - located close to rock-chip samples RO-18-01 to RO-18-03, which returned 0.35% to 1.22% WO3 as announced in July 2026.
-
The Northern Zone B anomaly lies within the modelled intrusive body resolved by the Company’s three-dimensional magnetic inversion, while the Rowland Main anomaly is associated with an interpreted magnetic-high lineament.
-
Soil geochemistry from the nearby White Star Tungsten Project (253 samples) remains pending and will be reported when received.
Phase 2 Soil Geochemical Survey Results
The Phase 2 soil survey comprises 315 samples, collected across the Rowland Tungsten Property on lines spaced approximately 100 metres apart with a sample spacing of 25 to 50 metres. The programme was designed to provide continuous geochemical coverage across the property to refine the targets as we progress to drilling.
Rowland Main Anomaly
The larger of the two anomalies lies around the historical Rowland Main workings from which the Company reported a high-grade rock-chip assay of 4.02% WO3 in July 2026. Eighteen samples define a footprint of approximately 190 metres east-west by 630 metres north-south, elongate north-northeast. Six samples exceed 100 ppm W, headlined by R079 at 4,240 ppm W and supported by R082 (422 ppm W), R119 (373 ppm W), R116 (215 ppm W), R078 (176 ppm W) and R120 (110 ppm W). Sample R079 also returned 66.9 ppm Sn against a survey median of 2.8 ppm, the highest tin value recorded in the survey, and a tungsten-tin association consistent with a greisen-modified skarn system.
Northern Zone B Anomaly
The second anomaly covers an area of 200m x 200m. The peak value is 228 ppm W at sample R188, supported by R155 (174.5 ppm W), R217 (136.5 ppm W), R156 (110.0 ppm W) and R218 (105.5 ppm W). The anomaly is centered on the rock-chip samples RO-18-01, RO-18-02 and RO-18-03, which returned 0.35%, 1.22% and 0.54% WO₃ respectively, as announced by the Company in July 2026. The anomaly is developed over tactite and calc-silicate hornfels and Prospect Mountain quartzite.
Relationship to Geophysics and Historical Workings
The two anomalies occupy different geophysical settings. Most of the strongest soil samples in the Northern Zone B area lie within the modelled intrusive body resolved at a susceptibility threshold of 0.010 SI by the three-dimensional magnetic inversion completed by East Coast Consulting, and the anomaly centre lies close to an interpreted magnetic-low lineament. The Rowland Main anomaly lies outside the modelled intrusive footprint and is associated with an interpreted magnetic-high lineament.
Next Steps
The soil geochemical results will be integrated with the completed UAV magnetic survey, the three-dimensional magnetic inversion and the rock-chip and channel assay results announced in July 2026 to advance drill target generation across the consolidated Jarbidge-Charleston tungsten footprint. Soil geochemistry from the nearby White Star Tungsten Project remains at the laboratory, and the Company will provide further updates as those results are received and interpreted.
Sample Assay Results
Quality Assurance and Quality Control (QA/QC):
Soil samples were collected and submitted to a certified independent laboratory, ALS Global, for preparation and analysis. Samples were dried at a maximum of 60 degrees C and screened to minus 180 microns (preparation code PREP-41), and analysed for 32 elements including tungsten by lithium borate fusion and inductively coupled plasma mass spectrometry (method ME-MS81). Lithium borate fusion was selected because tungsten is refractory and partial digestions under-report tungsten hosted in scheelite and wolframite. WO3 values presented in this news release are calculated from elemental tungsten (W) results using a conversion factor of 1.2611. Chain-of-custody protocols were maintained throughout. Quality control comprised field duplicates inserted at a rate of approximately one in 32 samples, together with the certified reference materials, blanks and duplicates inserted by the laboratory in each analytical batch. Soil geochemical values represent surficial dispersion and are not, and should not be interpreted as, indicative of grade or of any mineral resource.
