Vancouver, British Columbia — March 3, 2026 — Leads & Copy — Atomic Minerals Corporation (TSXV: ATOM) (OTCQB: ATMMF) (FSE: DO8) has announced the submission of drill permits for its South Lisbon Valley East property (SLVE) in Utah.
The SLVE property, spanning 1,516.5 acres (614 hectares), is situated approximately 35 kilometers NE of Monticello, Utah, within the Colorado Plateau. The property is positioned along the southern portion of a suspected belt of penecordant uranium mineralization hosted in the Moss Back member of the Triassic Chinle formation, associated with the northeastern side of the downfaulted Lisbon Valley anticline.
According to Atomic Minerals, evaluation of oil and gas drill holes in the Lisbon Valley area revealed gamma ray anomalies within the base of the Chinle Formation in several drill holes. This potentially outlines a uranium mineralization belt similar to the one found on the southwest side of the Lisbon Valley anticline.
Atomic Minerals plans to conduct an initial drilling program involving 18-20 drill holes across the property. The aim is to test for uranium mineralization and determine the full width of the suspected arcuate belt, according to CEO Clive Massey. Massey stated the company believes significant uranium mineralization is present within the target belt, analogous to the previously producing uranium belt on the southwest side of the Lisbon Valley Fault.
The company intends to drill a series of 4 to 5 fences across the property, utilizing existing road and trail infrastructure from historic oil and gas drilling. These fences will be placed near historic oil and gas holes that exhibited significant gamma ray spikes at the base of the Chinle formation.
The Colorado Plateau, covering roughly 130,000 square miles (336,700 square kilometres), is identified as the largest uranium province in the USA and one of the largest globally, having produced 597 million pounds to date. Uranium deposits in the Colorado Plateau are primarily found in the Triassic Chinle and Jurassic Morrison Formations, formed in arid environments. These deposits are exposed along cliffs and drainages and have been mined for vanadium since 1909 and uranium since 1946.
The Chinle Formation deposits are located in arcuate belts associated with a series of NW-SE trending anticlines developed as a result of salt movement in the underlying strata within the Paradox Basin. Paleo rivers flowed along each side of these anticlines with uranium mineralization found within these paleo-channels along the lengths of the anticlines. Lisbon Valley is the type location for Chinle deposits.
Lisbon Valley produced approximately 78 million pounds of U3O8 between 1952 and 1982 from an arcuate belt approximately 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 cut-off and displaced the uranium mineralization associated with the northeast flank, speculatively dropping it + 2500 feet on the northeast side of the fault.
Historical oil and gas drilling on the northeast down-faulted side of the Lisbon Valley anticline, largely between 2006 and 2014, located anomalous to extremely anomalous gamma ray readings in the suspected Moss Back Member in 28 of 51 holes drilled throughout a northwest trending belt 20 kilometres in length by + 750 metres in width, outlining the suspected eastern arcuate belt.
Within Atomic’s SLVE property nine widely-spaced historic oil and gas wells appear to define the southern end of this 20km by +750m belt as ‘off-scale’ radioactivity was recorded within the favorable Chinle Formation host rock over widths of 1.8 to 4.5 m (6 to 15 feet) from depths of 760 to 880 m (2,495 to 2,890 feet).
Atomic Minerals Corporation is an exploration company focused on uranium projects. Its property portfolio includes projects on the Colorado Plateau, in the Athabasca region of Saskatchewan, Canada, and at Mount Laurier in Quebec, Canada.
