Updated presentation highlights three past-producing U.S. tungsten assets, high-grade exploration results, advancing drill targets and Western Star’s strategy to progress projects toward potential NI 43-101 mineral resource definition

Vancouver, British Columbia – TheNewswire - August 19th, 2026 – Western Star Resources Inc. (CSE: WSR) (OTC: WSRIF) (FRA: 4K2) (“Western Star” or the “Company”) is pleased to announce the release of its newly updated investor presentation, providing shareholders and prospective investors with a comprehensive overview of the Company’s rapidly advancing North American critical-minerals portfolio and its strategy to build a significant U.S.-focused tungsten exploration platform.

The updated presentation brings together, for the first time in a single corporate document, the historical production record, modern exploration results, geophysical interpretation, surface sampling, emerging drill targets and planned advancement strategy across Western Star’s Eagle Point, Rowland and White Star tungsten projects in the United States, together with the Company’s drill-permitted polymetallic Western Star Project in British Columbia.

The presentation is available through the Company’s website at www.westernstarresources.com .

Western Star believes the updated presentation demonstrates the significant transformation undertaken by the Company over the past year — from acquiring historically productive mineral assets to actively generating modern exploration data and advancing priority targets toward drill testing.

The Company's U.S. tungsten strategy is now centred around three past-producing projects in two established U.S. mining jurisdictions , each offering a different stage of exploration opportunity and together providing Western Star with a growing pipeline of potential drill targets.

A U.S. TUNGSTEN PORTFOLIO MOVING FROM HISTORY TO MODERN EXPLORATION

The updated presentation highlights:

Eagle Point, New Mexico: a 100%-interest, past-producing tungsten project hosting eight historically mapped skarn bodies along approximately 1,500–2,000 feet of prospective granite-limestone contact [3]. Historical production totalled approximately 1,800 tons of scheelite-bearing material shipped to the U.S. Government stockpile at Deming during 1943–44, settled on a basis of 0.48% WO [1][2]. Surface sampling by the U.S. Geological Survey and the New Mexico Bureau of Geology and Mineral Resources (USGS/NMBGMR) includes sample LH705, a scheelite-rich outcrop sample, returning 27.6% WO₃ and 0.98% Mo [4]. In 1955 the U.S. Government prepared and recommended a Defense Minerals Exploration Administration exploration contract (Idm-E783, Docket DMEA-3701) under which it would have funded 75% of an exploration program involving shaft sinking and diamond drilling [3]. Historical estimates associated with Eagle Point are historical in nature, are not NI 43-101 compliant and are not being treated by the Company as current mineral resources or mineral reserves - see “Historical Estimates” below.

Rowland, Nevada: a past-producing tungsten project where Western Star’s 2026 exploration program returned selected rock, float and channel results of up to 4.02% WO , (sample RO-16-01, Rowland Main), as disclosed in the Company’s news release dated July 28, 2026. Soil geochemistry (news release dated July 10, 2026), UAV magnetics (news release dated June 17, 2026) and geological mapping have identified Central and Rowland Main as principal exploration target areas within an approximately one-kilometre geochemical corridor.

White Star, Nevada: a 100%-owned project adjacent to Rowland, where a 2026 selective rock sample (WS-16-02) returned 3.00% WO₃ and 711 ppm Mo as disclosed in the Company’s news release dated July 28, 2026. The Company’s first modern high-resolution UAV magnetic dataset, reported on July 15, 2026, has identified multiple interpreted target zones beyond the known historical workings.

Together, Rowland and White Star form the Company’s consolidated Jarbidge–Charleston tungsten footprint, an exploration concept covering more than six kilometres of prospective tungsten-bearing horizons. The Company has initiated drill-permitting activities with a USFS Plan of Operations due to be submitted shortly to cover the consolidated Jarbidge–Charleston district.

The updated presentation also provides investors with detailed project maps, historical workings, geological interpretations, sampling locations and geophysical datasets that illustrate how Western Star is progressively moving its U.S. portfolio from historical information toward modern target definition.

EAGLE POINT: POTENTIAL PATHWAY TOWARD RESOURCE DEFINITION

A central element of Western Star's forward strategy is the systematic advancement of the Eagle Point Tungsten Project .

The Company intends to use modern mapping, geochemistry, geophysics and, subject to permitting, financing, final drill design, contractor availability and other customary considerations, drilling to test historically identified tungsten mineralization and selected extensions.

Western Star's objective is to generate sufficient modern geological, analytical and QA/QC information to determine whether Eagle Point may ultimately support the preparation of a maiden mineral resource estimate in accordance with National Instrument 43-101 – Standards of Disclosure for Mineral Projects .

As previously disclosed by the Company in its news release dated August 4, 2026, Western Star is targeting a maiden Eagle Point drilling program during 2026, subject to the foregoing conditions. The proposed program is intended to investigate the geometry, grade and continuity of historically identified tungsten-bearing skarn mineralization while also testing selected opportunities along strike and at depth.

There can be no assurance that future drilling or exploration will result in the definition of a mineral resource , nor that any mineralization identified will ultimately be demonstrated to be economically recoverable.

ROWLAND AND WHITE STAR: BUILDING A NEVADA DISTRICT-SCALE TARGET PIPELINE

In Nevada, the updated presentation illustrates the progression of Western Star's exploration strategy from acquisition and land expansion through geophysics, geochemistry, sampling and now drill-target definition.

At Rowland, 93 soil samples collected during the Company's 2026 program produced a coherent tungsten-copper-molybdenum-bismuth geochemical signature extending across an approximately one-kilometre structural corridor. The strongest soil anomalies coincide with UAV magnetic gradients and with interpreted intrusive-carbonate contacts, after the regional mapping of Coats (1964) [6], with Central and Rowland Main emerging as the principal current exploration target areas .

At adjoining White Star, Western Star is integrating magnetic interpretation, surface geochemistry, mapping and its 3.00% WO₃ selective rock result as it works to rank additional targets across the broader Nevada exploration position. Three-dimensional inversion of the geophysical dataset is being completed as part of this process; the results of that work will be disclosed by news release when received.

The Company believes this systematic approach provides a disciplined pathway for determining which targets warrant future drill testing.

U.S. CRITICAL-MINERAL POLICY AND POTENTIAL GOVERNMENT SUPPORT

Tungsten's importance to defence, aerospace, advanced manufacturing and technology has placed secure critical-mineral supply chains firmly within U.S. strategic policy discussions.

Western Star intends to continue assessing available U.S. federal programs that may support domestic critical-mineral exploration, development and supply-chain security, including potential grant, cost-sharing and other non-dilutive funding opportunities where the Company's projects satisfy applicable eligibility criteria.

As previously disclosed on August 4, 2026, the Company has submitted an application in response to a U.S. Defense Industrial Base Consortium solicitation relating to reliable supplies of strategic critical minerals .

There is no assurance that the Company will qualify for, be awarded or receive funding under that solicitation or any other government program.

The historical precedent at Eagle Point is notable: in 1955 the U.S. Government prepared and recommended a Defense Minerals Exploration Administration exploration contract (Idm-E783, Docket DMEA-3701) under which it would have funded 75% of a proposed exploration program involving shaft sinking and diamond drilling. That contract never became effective, and the program was never carried out [3].

CEO COMMENTARY

Blake Morgan, President and Chief Executive Officer of Western Star Resources, commented:

“The purpose of this new presentation is to show investors exactly what Western Star has built and, more importantly, where we intend to take it next.

“We have assembled three past-producing tungsten projects in the United States and we are no longer simply talking about historical potential. At Rowland and White Star we have generated modern geophysics, geochemistry and certified laboratory results. At Rowland, drill permitting has commenced. At Eagle Point, we are working toward systematically testing a tungsten system that attracted significant U.S. Government attention historically, but where the principal government-backed drilling program was never completed.

“What excites us about Eagle Point is the combination of historical production, eight mapped skarn bodies, exceptional reported surface results and a system that remains largely untested using modern exploration techniques. Our objective is to generate the modern drilling and geological data necessary to determine whether Eagle Point can support a maiden NI 43-101 mineral resource estimate, while at the same time testing the broader exploration potential of the system.

“Nevada gives us a second major exploration front. Rowland and White Star now provide us with a substantial district-scale target pipeline, and the integration of modern geophysics, geochemistry and mapping is allowing us to increasingly focus our exploration dollars on the highest-priority areas.

“The strategy from here is disciplined: define the targets, obtain the necessary approvals, drill the best opportunities and, where the results and data support it, advance our projects toward compliant mineral resources.

“At a time when the United States is placing increasing strategic emphasis on secure supplies of critical minerals, we believe Western Star has assembled a highly relevant portfolio. We intend to aggressively pursue the geological opportunity while remaining disciplined on capital and focused on creating long-term value for shareholders.”

ADDITIONAL CANADIAN EXPLORATION OPTIONALITY

The updated investor presentation also highlights Western Star's 100%-owned Western Star Property in the Revelstoke Mining District of British Columbia .

The 4,740-hectare (46.4 km²) project is permitted for a multi-pad drill program with the associated government bond paid, as disclosed by the Company on September 18, 2025, and hosts twelve documented MINFILE mineral occurrences on the Western Star Property together with three further occurrences on the adjoining Discovery Property, across a mineralized trend reported to extend for more than 6.2 kilometres [7]. This mineral-occurrence information is drawn from third-party government records and has not been verified by the Qualified Person. The property provides Western Star with additional exposure to gold, silver, copper, lead and zinc mineralization while the Company's principal corporate focus remains the advancement of its U.S. tungsten portfolio.

Historical Estimates

The historical estimates referred to in this news release are those disclosed in the Company’s news release dated August 11, 2026, being the estimate of J. N. Faick, Geologist, U.S. Geological Survey, and Harrison Schmitt, Consulting Geologist to the then applicant, of a historical mineralized system on the order of approximately 170,000 tons of mineralised tactite exposed at surface, comprising approximately 70,000 tons grading 0.40% WO₃ and approximately 100,000 tons grading 0.25% WO₃ [3]. These historical estimates are historical in nature and were prepared prior to the implementation of National Instrument 43-101 – Standards of Disclosure for Mineral Projects (“NI 43-101”). A Qualified Person has not completed sufficient work to classify the historical estimates as current mineral resources or mineral reserves, and the Company is not treating the historical estimates as current mineral resources or mineral reserves. The estimates rest on surface trenching, ultraviolet-lamp observation and sparse grab and chip sampling, without drill support or documented quality control, and separate estimates diverge by a factor of three to four; the Company therefore regards their reliability as low and their relevance as limited to context on historical exploration. Verification as current mineral resources would require detailed mapping, systematic channel sampling under a documented QA/QC protocol, and drilling of sufficient density to establish grade and geometric continuity, followed by independent data verification and estimation by a Qualified Person. The historical estimates are presented solely to provide context regarding the historical exploration of the Eagle Point Property and should not be relied upon as current mineral resources or reserves.

Quality Assurance and Quality Control

Rock-chip, float and channel samples referred to in this news release were collected by the Company’s field crew under the supervision of a Qualified Person and submitted to ALS Global (Reno, Nevada), an accredited laboratory independent of the Company, for preparation and analysis. Samples were analysed for tungsten and 47 additional elements by method ME-MS61, with over-limit tungsten determinations by fusion XRF. Soil samples were collected at a nominal 25-metre spacing and analysed by the same laboratory. Full details of the Company’s sampling methodology, analytical procedures and quality-control protocols are set out in the Company’s news releases dated July 10, 2026 and July 28, 2026. Selected rock, float and channel samples are selective in nature and are not necessarily representative of the mineralization hosted on the Company’s properties.
