American Atomics Completes And Files NI 43-101 Technical Report On Its Lisbon Valley East
American Atomics Inc. has completed and filed a National Instrument 43-101 compliant Technical Report for its Lisbon Valley East project located in San Juan County, in the State of Utah. The Company holds the rights to acquire up to an 80% interest in the Property through an option assignment agreement with Big Indian Prospectors LLC, as optionor, signed and previously announced on March 11, 2026. The Report has been prepared in accordance with the guidelines set out in the Canadian Securities Administrators' National Instrument 43-101 Standards of Disclosure for Mineral Projects. The Report titled 'Technical Report Lisbon Valley East Property' with an effective date of March 27, 2026, has been filed under the Company's profile on SEDAR+ and is also available on the Company's website. Lisbon Valley East lies approximately 35 miles (56 kilometres) southeast of Moab, Utah and consists of 217 Bureau of Land Management lode claims. Lisbon Valley produced approximately 80 million pounds of U3O8 between 1950 and 1990 from an arcuate belt some 16 miles long by 1 mile wide with approximately 1/3 of the belt eroded away post mineral. Individual ore bodies ranged from a few hundred pounds to 20,000,000 pounds of U3O8, hosted in the basal Moss Back Member of the Triassic Chinle Formation along the southwest flank of the Lisbon Valley anticline. A northwest trending, post-mineral normal fault, the Lisbon Valley Fault, abruptly cutoff and displaced the uranium mineralization associated with the northeast flank, speculatively dropping it + 2,500 feet on the northeast side of the fault. The Lisbon Valley East property was staked targeting the suspected arcuate uranium belt on the downfaulted northeastern side of the Lisbon valley anticline, which the author of the Report believes lies at 2,500 to 2,800 feet below surface based on the following factors: The North Alice ore body at the north end of the southwestern arcuate uranium belt ends abruptly at the Lisbon Valley fault, not due to a drop in grade or mineralization, but due to fault displacement, strongly suggesting uranium mineralization continued pre-fault. The Rio Algom mine was subsequently discovered on the down-dropped footwall side of the fault, which Lahusen (1977) speculated was the actual continuation of the North Alice ore body. The North Alice Orebody produced 6,000,000 pounds of U3O8 at a grade of 0.25% U3O8 (Lahusen,1977), while the Lisbon Valley mine produced 13,000,000 pounds of U3O8 at the same 0.25% U3O8 grade (Chenoweth, 1990). Drilling by Mesa Uranium Corp. and Universal Uranium Ltd. in the 2006 and 2007 period located anomalous uranium mineralization at the base of Chinle Formation in the Moss Back Member, with one highlight 3.5-foot intersection of 0.28% U3O8, further proving the Moss Back Member is uranium-bearing on the down faulted side on the anticline. Oil and gas drilling in the 2000's and early 2010's on the northeast down-faulted side of the Lisbon Valley anticline located anomalous to extremely anomalous gamma ray readings in the suspected Moss Back Member in 28 of 51 hole drilled throughout a northwest trending belt 20 kilometers in length by + 750 meters in width, outlining the suspected eastern arcuate belt.
