Western Star Resources Expands Its Past Producing Rowland Tungsten Property by 170%, Securing Mine Workings in Elko, Nevada, USA.

14:00 Uhr  |  The Newswire

New land position encompasses historical adits and expands district - Western Star Resources Inc. (CSE: WSR) (OTC: WSRIF) (the "Company" or "Western Star") is pleased to announce it has expanded the Rowland Tungsten Property in Elko County, Nevada, USA by 170% through physical claim staking. The expanded land package now encompasses historical mine workings, including a newly identified adit, and positions the Company to pursue district-scale tungsten exploration in one of Nevada's most established mining jurisdictions.

Key Highlights:

• LiDAR analysis identified previously unrecognized waste dumps and an adit located north of the original claim block, now secured within the expanded land position

• Historical production of over 1,000 tons of ore grading up to 3.38% WO was reported between 1943 and 1956¹ at workings along trend from the expanded claim bouary

• Newly identified adit is hosted within mapped intrusive units, suggesting current geological mapping of prospective horizons may require revision

• Skarn mineralization is hosted within contact metamorphic zones up to 100 feet wide, developed along intrusive contacts with Cretaceous quartz monzonite

• Field crews are expected on-site within weeks to sample, re-map, and better define the orientation of mineralized horizons

Blake Morgan, the CEO and President of Western Star, stated "Expanding the land package by over 170%, we are building a district scale land package in a highly prospective area for Tungsten."

Property Overview

The Rowland Tungsten Property is a road-accessible past-producing project located approximately six miles southwest of Jarbidge in northeastern Nevada, within the well-established Jarbidge mining district. The property geology is characterized by limestones, shales, and quartzites intruded by a Cretaceous-aged quartz monzonite stock. This intrusive event drove contact metamorphism, forming skarn and hornfels zones up to 100 feet wide, and is the primary prospective environment for tungsten mineralization.

Key Property Highlights:

• Historical production of over 1,000 tons of ore containing up to 3.38 percent WO between 1943 and 1956

• High-resolution LiDAR review has identified over 17 historical open pits, trenches, shafts and adits.

• Extensive historical workings are expected to classify the project as previously disturbed and are expected to streamline the permitting process.

• Tungsten mineralisation traced over 2km - the full length of the existing property package, indicating scale potential. Which as now been increased by 170%

• 2026 Spring Work program includes:

  • Sampling historical workings to verify high grade tungsten mineralisation and;

  • property wide UAV magnetometer survey

• Mineralization hosted in skarn zones up to 100 feet wide, developed along intrusive contacts

• Presence of scheelite (WO) with molybdenite, powellite, chalcopyrite, and pyrite within a garnet-epidote skarn system

• The work program is being designed to advance the project towards the drill targeting stage around the zones of high-grade tungsten.

Discovery of Historic Workings on New Ground

LiDAR data review identified several areas of ground disturbance north of the original claim boundary that were obscured beneath tree cover and invisible on standard satellite imagery. By penetrating the vegetation canopy, LiDAR revealed features consistent with waste dumps. Subsequent review of historical topographic maps confirmed the presence of an adit in this area. Notably, the adit is situated within a zone mapped as dominantly intrusive which in the Rowland setting not typically associated with contact skarn mineralization. The low cost of staking made securing the ground a straightforward and prudent decision adding to the company's exploration pipeline.

Field teams will visit the area in the coming weeks to collect samples and conduct remapping to better constrain the distribution and orientation of prospective mineralized horizons.

2026 work program overview

Since acquiring the Rowland property in Q4 2025, the company has compiled the available historical data, completed a LIDAR review to identify areas that indicate historic mining activity and undertaken a local and regional geological assessment.

Geology

The project is underlain by limestones, shales, and quartzites which have been intruded by a Cretaceous-aged quartz monzonite stock. This intrusive event drove contact metamorphism, forming skarn and hornfels zones up to 100 feet wide. Tungsten mineralization occurs primarily as scheelite, both as coarse crystals and fine disseminations, associated with molybdenite, powellite, pyrite, and chalcopyrite within a garnet-epidote-quartz-calcite skarn system.

The granite-carbonate contact represents the primary zone of prospectivity. Notably, the most intense historical mineralization occurs approximately 1 km from the mapped intrusive contact, suggesting potential structural or fluid pathway controls beyond simple contact geometry.

Structural Control and Geophysics

Historical mapping indicates southwest-northeast trending faults and a central thrust fault across the property. Existing workings appear spatially associated with these structures; however, the absence of modern, high-resolution geophysics has limited interpretation.

To address this, Western Star will conduct a high-resolution UAV magnetic survey (50 m line spacing), representing the first modern geophysical survey on the property. This survey is design to refine the company's structural interpretation, map intrusive contacts at high resolution and identify additional skarn targets.

Geochemical Sampling

The Company will undertake systematic rock sampling of all historically disturbed areas identified through LiDAR analysis. This work will focus on:

• Verifying historical grades

• Defining mineralized zones

• Establishing vectors toward higher-grade mineralization

In addition, orientation soil sampling will be conducted to evaluate the effectiveness of soil geochemistry ahead of a potential larger-scale survey.

Permitting and Future Plans

The company is initiating the necessary streams of work to submit Notice of Intent to the relevant permitting authority in Elko County. The Company aims to advance permitting in parallel with exploration to position the project for drill testing of high-priority targets.

Past Producing Rowland Property

The Rowland property only has the following option requirements remaining to fulfil the 100% ownership. The company plans to pay these over the coming weeks to complete the 100% full ownership. All other Option Requirements have been fulfilled.

Option to earn 100% interest in the Rowland Property

(a) Fifteen thousand dollars (US$15,000.00) on or before July 1, 2026;
(b) Fifteen thousand dollars (US$15,000.00) on or before July 1, 2027; and
(c) Twenty thousand dollars (US$20,000.00) on or before July 1, 2028.

Past Producing Rowland Property 170% Extension

The new 170% Extension of the past producing tungsten property, the Rowland, is now 100% owned by Western Star Resources!
