+Added: Uranium Ridge Project
+Added: The Uranium Ridge is located on Bureau of Land Management (BLM) land
+Added: in Montrose County, Colorado, situated approximately 10 road miles from Western’s Mustang Mineral Processing Plant.
+Added: combines the historically drilled Baboon Basin and Sawtooth claims with newly acquired adjacent lode claims and serves as a key satellite
+Added: deposit supplying feedstock for Western’s milling facilities.
+Added: The property contains high-grade uranium and vanadium in the Salt
+Added: Wash Member of the Morrison Formation and will present significant ore transportation cost savings.
+Added: In addition to the acquired mining
+Added: claims, Western staked an additional surrounding 38 mining claims, based upon the trend of the mineralization at the site.
+Added: Accessibility
+Added: The site is accessible by public roads year round,
+Added: however, a portion of these roads will require repair.
+Added: The property was acquired in 1996 by two private
+Added: partners (each owning 50% of the Property separately and not jointly) as an investment that leveraged their combined expertise as a geologist
+Added: and a surveyor.
+Added: The latter partner was notably from a prominent local uranium family.
+Added: Over the course of ownership, the partners periodically
+Added: made the Property available for sale during periods of strong uranium prices.
+Added: Following the passing of one of the original partners in
+Added: 2013, Western’s CEO George Glasier acquired that partner’s interest from his estate.
+Added: As a result, the property has since
+Added: been held by the remaining original partner and Mr.
+Added: Glasier, each owning the separate but contiguous mining claim packages.
+Added: Due to personal circumstances, the remaining
+Added: original partner recently offered his interest to Mr.
+Added: However, due to high potential for added value to the Company, Mr.
+Added: first presented this opportunity to Western.
+Added: The Company determined that acquiring the drilled-out Claims represented a compelling opportunity
+Added: when combined with the leveragability of the larger land package surrounding the property.
+Added: To consolidate ownership, Mr.
+Added: Glasier indicated
+Added: his willingness to make his personal interest available to the Company on appropriate terms if the Company deemed it to be desirable.
+Added: On October 14, 2025, Western acquired the package
+Added: of unpatented mineral lode claims and secured a 50% ownership in the Uranium Ridge.
+Added: In connection with Western’s purchase of its 50% interest in
+Added: the Baboon Basin and Sawtooth claims, Western staked its 100% interest in an additional surrounding 38 mining claims.
+Added: The original owners of the Property, Nuclear Dynamics
+Added: Inc., engaged Thamm, Mickel & Co.
+Added: to prepare an independent ore reserve calculation;
+Added: the report was issued August 14, 1980 (the “Thamm
+Added: Report” or “Report”).
+Added: The Report was compiled utilizing data from 175 drill holes drilled between 1977 and 1980, but
+Added: did not utilize a superior calculation method, such as the Kriging calculation or the polygonal method.
+Added: The Thamm Report was prepared
+Added: approximately 20 years before National Instrument 43-101 Standards of Disclosure for Mineral Projects was adopted by the Canadian Securities
+Added: Administrators.
+Added: Therefore, the Thamm Report is not current or public.
+Added: Accordingly, the Company is not presenting the findings of the Report.
+Added: The property encompasses the previously drilled-out
+Added: Baboon Basin/Sawtooth claims, as well as additional claims surrounding Baboon Basin/Sawtooth.
