Myriad acquires 23 breccia pipe uranium, REE targets in Arizona

All Targets Optioned to Wedgemount Resources Vancouver, British Columbia--(Newsfile Corp. - June 9, 2026) - Myriad Uranium Corp. (CSE: M) (OTCQB: MYRUF) (FSE: C3Q) ("Myriad" or the "Company") is pleased to announce the acquisition of 15 state mineral leases and 8 split-estate claims in Arizona, covering 5,600 acres, the former by way of award. Two additional state mineral awards are pending, which would bring the total to 6,080 acres. These leases and claims contain a total of 23 breccia pipe-hosted uranium targets with potential for associated rare earth elements (REEs).

The properties (together, the "Breccia Pipe Project" or the "Project") are located in the "Arizona Strip" of Northern Arizona, a historically significant uranium district. (See Figure 1 below). Among the 23 targets is the Wate Pipe, the subject of a historical resource estimate of 71,000 tons containing 1.12 million lbs eU₃O₈ at an average grade of 0.79% eU₃O₈ (historical, not current under NI 43-101 – see "About the Wate Breccia Pipe Historical Resource Estimate" for details). Myriad has granted Wedgemount Resources Corp. ("Wedgemount") a 3-year option as of June 8, 2026, to acquire up to 75% of the Breccia Pipe Project and an area of mutual interest, with Myriad retaining the right to subsequently earn back a 25% interest and establish a 50/50 joint venture ("the Option").

Under the Option, Wedgemount will acquire up to a 75% interest in the Project by (1) paying Myriad US$75,000 (approximately Cdn$104,500) within 30 days; (2) issuing common shares to Myriad over the Option period such that Myriad ultimately owns 9.9% of Wedgemount; and (3) incurring qualifying expenditures of Cdn$4,000,000 over the Option period. Myriad retains the right to earn back to a 50% interest in the Project by funding the next Cdn$5,000,000 of qualifying expenditures. See "Wedgemount Option Details" below for further details.

Myriad's Chairman Simon Clarke commented: " The acquisition of these mineral leases places us squarely in a historically significant uranium district with current uranium production nearby. Additionally, it is also a district which we believe is very underexplored and the targets that we have acquired have not had any modern exploration techniques applied to them. The opportunity was brought to us by the same source who was instrumental in putting together our Red Basin Project, and who was involved in drilling several of the key targets on this Project during the last uranium cycle pre-Fukushima.

"We have been steadily adding key targets and land over the last few months and are now in position to drive the Project forward and have once again determined that, while the Company focuses on our large-scale, flagship project at Copper Mountain, Wyoming, it makes sense to bring in the right partner to drive day to day operations while we retain significant ownership. We believe that Wedgemount is the right partner to do this and, with them bearing the costs of exploration and development over the next 3 years, our ability to keep up to 50% ownership represents good upside potential for Myriad and its shareholders with additional exposure to the Project coming from the share ownership we will also acquire in Wedgemount. This, and our recent sale of 90% of Red Basin to Subatomic, are examples of transactions that meet our strategy of looking to add projects that we deem highly prospective, based on a history of uranium exploration or production, but, without taking our focus or time away from our exploration and development of our Copper Mountain Project."
