MYRIAD URANIUM COMPLETES HIGH-RESOLUTION GROUND GEOPHYSICS AT RED BASIN, SECURES 100% OWNERSHIP, AND LAUNCHES MARKET AWARENESS PROGRAM

Myriad Uranium Corp. has completed ground radiometric and magnetic surveys over the original claim areas that were the subject of the 100-per-cent earn-in to the Red Basin project, New Mexico. The area comprises 86 lode claims in the Red Basin area of the Datil Mountains-Pietown uranium district, Catron county, New Mexico, United States, covering approximately 1,776 acres (approximately 719 hectares). The completion of this phase of work fulfills Myriad's earn-in requirements under the option agreement dated Jan. 30, 2025, with First American Uranium Inc. and its 60-per-cent-owned subsidiary, First American Energy Fuels Ltd., respecting the claims, and Myriad has now earned a 100-per-cent interest in and to the claims.

Myriad also announces the engagement of Machai Capital to enhance investor awareness. Further details are provided below.

Thomas Lamb, Myriad's chief executive officer, commented: "We are delighted to complete this earn-in to 100-per-cent ownership of Red Basin. The entire basin is estimated to contain up to 45 Mlb of uranium and our acreage within it is excellent, comprising the vast majority of historical drilling and known resources. Mineralization is hosted in thick sections of channelized roll-front deposits hosted in permeable sandstones from surface to depths of less than 450 feet. The setting and nature of the mineralization suggests there may be numerous extraction options that could be considered, including in-situ recovery. We are currently advancing a large-scale exploration permit for the project and this high-resolution ground survey will help us optimize it.

"We are also pleased to announce a significant new investment in investor awareness with the engagement of Machai Capital. With recent milestones achieved and additional developments on the horizon, this is the right moment to expand our international visibility as we advance our projects."

Ground geophysical survey parameters and results

The ground magnetic and radiometric surveys were conducted at 50-metre-line spacing along a north-south orientation.

• The magnetic survey was completed with 160 line kilometres of total data collected. Crews operated a Geometrics MagEx portable cesium-vapor magnetometer paired with a Geometrics MagStation base station for diurnal corrections. Both the rover and base sampled at five hertz. With an average walking speed of approximately four kilometres/hour, the resulting station spacing was roughly 0.2 m.
• Gamma mapping covered 142 line km over the same grid area. The crew used an ERG RadScout mapping system consisting of RadScout software on a Juniper handheld, receiving counts from a Ludlum Model 3,000 metre connected to a Ludlum 44-10 scintillation detector. The 44-10 uses a two-inch-by-two-inch NaI (Tl) crystal, which provides high sensitivity for total-count gamma surveys. Sampling was at one Hz, giving an average station spacing of approximately one m.

Final data and outputs are expected in the coming weeks. The magnetic image shows channel-like features that appear to correlate with existing drainage patterns for the most part but may also give indication of subsurface channels. Further interpretation and ground-truthing of the data and its determination of its utility for exploration targeting is still planned.

Geology and mineralization at Red Basin

Exploration and minor production in the Red Basin district dates back to the 1950s with approximately 1,194 pounds of U3O8 (triuranium octoxide) produced from ore with an average grade of 0.17 per cent U3O8 (McLemore & Chenoweth, 2017). No formal production is known to have occurred within the project area itself. Gulf Oil and Occidental Petroleum drilled more than 1,050 holes in the Red Basin project area in the late 1960s through the early 1980s, most of which are located within Myriad's current claim areas.

Mineralization is hosted in channelized roll-front deposits within permeable sandstones of the Crevasse Canyon formation and pre-Baca formation paleosols. Historical drilling on the project has delineated a thick section of roll-front type uranium-vanadium mineralization cropping out on the surface to approximately 450 feet down dip. The meandering uranium-vanadium bearing sandstones can be more than a mile in length and 600 or more feet wide. The host formations are amenable to open pit or underground mining and possibly in-situ leaching.

A 1980 assessment of uranium resources in the Colorado Plateau physiographic province (U.S. Department of Energy, 1980) estimated that Myriad's Red Basin project contains approximately 1.6 million pounds U3O8 at an average grade of 0.31 per cent U3O8. In 2012, Rio Grande Resources commenced a geologic evaluation of the drill hole gamma ray electric logs. Stratigraphic cross-sections were constructed, two separate roll fronts were mapped and additional resources were estimated. Readers are cautioned that historical resource estimates should not be relied upon to judge the quality of exploration potential of the Red Basin project (see note on historical estimates).

An open-file report (No. 138) produced by the New Mexico Bureau of Mines and Minerals (Chamberlin, 1981) indicates that the Red Basin area could contain as much as 30 million to 45 million pounds of U3O8. In addition, the deposits could contain significant amounts of associated vanadium, up to 1.64 per cent V2O5, as reported by Bachman et al. (1957).

Historical estimates

While Myriad Uranium has determined that the historical estimates described in this news release are relevant to the Red Basin project area and are reasonably reliable given the authors and circumstances of their preparation, and are suitable for public disclosure, readers are cautioned not to place undue reliance on these historical estimates as an indicator of current mineral resources or mineral reserves at the project area. A qualified person (as defined under National Instrument 43-101) has not done sufficient work to classify any of the historical estimates as current mineral resources or mineral reserves, and Myriad Uranium is not treating the historical estimates as a current mineral resource or mineral reserve. Also, while the Red Basin claims contain all or most of each deposit referred to, some of the resources may be located outside the current Red Basin project area. Furthermore, the estimates are decades old and based on drilling data for which the logs are not available to Myriad.

From Myriad Uranium's viewpoint, limitations include that the company has not been able to verify or validate historical data. To verify the historical estimates and potentially restate them as current resources, a program of digitization of available data would be required. This must be followed by relogging and/or redrilling to generate new data to the extent necessary that it is comparable with the original data, or new data that can be used to establish the correlation and continuity of geology and grades between boreholes with sufficient confidence to estimate mineral resources.

Qualified person

About Myriad Uranium Corp.

Myriad Uranium is a uranium exploration company with an earnable 75-per-cent interest in the Copper Mountain uranium project in Wyoming, United States. Copper Mountain hosts several known uranium deposits and historic uranium mines, including the Arrowhead mine which produced 500,000 pounds U3O8 (triuranium octoxide). Copper Mountain saw extensive drilling and development by Union Pacific during the late 1970s including the development of a mine plan to fuel a planned fleet of California Edison reactors. Operations ceased in 1980 before mining could commence due to falling uranium prices. Approximately 2,000 boreholes have been drilled at Copper Mountain and the project area has significant exploration upside. Union Pacific is estimated to have spent $117-million (2024 dollars) exploring and developing Copper Mountain, generating significant historical resource estimates. The company also holds a 100-per-cent interest in the Red Basin uranium project in New Mexico, which has a near-surface mineralization, with significant upside potential.
