STRATHMORE EXPANDS AGATE PROJECT AREA AS DRILLING PROGRAM EXCEEDS EXPECTATIONS

Strathmore Plus Uranium Corp. has staked strategic mineral claims at the company's flagship Agate exploration project in Wyoming's prolific Shirley basin uranium mining district. This spring's drill program continued to expand the Agate mineralization, which appears open in all directions. Strathmore's Agate property benefits from roll-front deposits that extend from adjacent lands formerly operated by major historic producers such as Kerr McGee, Getty and Utah International/Pathfinder Mines (now UR Energy). Agate flanks projects held by Cameco and UEC and lies near UR-Energy's satellite in-situ recovery (ISR) mine, which has now been in production since April, 2026. The Shirley basin is an area of significant potential discovery and an ever expanding operational district for the development of uranium assets.

The nine lode mineral claims (186 acres) were staked to the east of one the company's most northeasterly drill holes completed on the project, AG-292-26, which encountered 14.5 feet of 0.063 per cent eU3O8 (radiometric equivalent triuranium octoxide) from 81.5 to 96 feet deep (see release dated May 5, 2026). This drill hole was positioned along the eastern extent of the project boundary, confirming discovery of a new uranium trend in the middle sand, extending over 2,500 feet in length. The continuing success at the Agate project is very encouraging with continuing review of available lands for acquisition and future exploration and discovery of uranium in the Shirley basin.

John DeJoia, PGeo, a Strathmore director who has mined nearly 20 million pounds of uranium and has drilled thousands of holes in the Shirley basin, said: "With the latest development of significant mineralization in the Middle Sand of our Agate property, our position takes on a very serious look. As has been stated in past news releases, the largest historical production in SB has been in the Middle Sand. With this recent Middle Sand exploration success, Strathmore's Agate property takes on a potential mineralization multiplier. I look forward to acquiring more land and hopefully finding the mineralization channel that connects to the major mining district to the east."

About the Agate property

The Agate property consists of 124 wholly owned lode mining claims covering approximately 2,560 acres. Uranium mineralization is contained in classic Wyoming-type roll fronts within the Eocene wind river formation, an arkosic-rich sandstone. Historically, 53 million pounds of uranium were mined in Shirley basin, including from open-pit, underground and the first commercial in-situ recovery operation in the United States during the 1960s. At the property, the uranium mineralization is shallow, from 20 to approximately 150 feet deep, much of which appears below the water table and likely amenable to in-situ recovery. Kerr McGee Corp., the largest U.S. uranium mining company at the time, completed extensive drilling across the greater project area in the 1970s, delineating areas of historical resources and potential mineralization. Strathmore has completed 294 holes during the 2023 to 2026 drilling programs, including installation of five monitor wells for groundwater studies and recovery of core for chemical assays and XRF analysis at the University of Wyoming.

About Strathmore Plus Uranium Corp.

Strathmore is focused on discovering uranium deposits in Wyoming, and has three permitted uranium projects including Agate, Beaver Rim and Night Owl. The Agate and Beaver Rim properties contain uranium in typical Wyoming-type roll-front deposits based on historical drilling data. The Night Owl property is a former producing surface mine that was in production in the early 1960s.
