Mkuju Corridor Uranium Project

The Mkuju Corridor Uranium Project is a 1,328 km² exploration portfolio comprising five prospecting licences in the Block A uranium corridor of the Ruvuma Karoo Basin, southern Tanzania. The licences sit immediately adjacent to the Nyota uranium deposit — hosting 156.6 Mlbs of adjusted U₃O₈ — and the Likuyu North deposit, both controlled by established international uranium developers.

The flagship prospect within the corridor is SWC-Mtonya, where a 12-kilometre radiometric anomaly has been delineated from regional airborne coverage. Historical auger results returned up to 3,825 ppm U₃O₈, and AURX's recent trench programme returned peak assays of 7,139 ppm U₃O₈ — grades that place SWC-Mtonya among the highest-grade surface uranium intercepts reported anywhere in the Karoo uranium province.

The Mkuju uranium province is a classic Karoo-age sedimentary roll-front system. Host stratigraphy comprises fluvio-lacustrine sandstones, siltstones and carbonaceous mudstones of the Karoo Supergroup, deposited in intracontinental rift basins during the Permo-Triassic. Uranium was mobilised from overlying granitoid source terrains by meteoric groundwater, transported in oxidised form, and precipitated at redox fronts where reducing conditions — typically organic carbon or sulphide — arrested the flow.

Mineralisation at Nyota and Likuyu North occurs as tabular, flat-lying bodies in palaeochannel sandstones. The same redox-front architecture extends across AURX's licence package, with the SWC-Mtonya anomaly interpreted as a continuation of the principal mineralised trend. The roll-front style is amenable to in-situ recovery (ISR) extraction, the lowest-cost and lowest-footprint uranium mining method currently deployed globally.

The project benefits from three reinforcing technical pillars. First, a proven regional endowment — Nyota's 156.6 Mlbs of contained uranium demonstrates that the Mkuju corridor hosts economically significant deposits. Second, a delineated 12-kilometre radiometric anomaly with peak trench assays to 7,139 ppm U₃O₈, comparable to or exceeding grades reported from the adjacent producing deposits. Third, a mineralisation style well-suited to modern low-cost ISR extraction.

Into this technical thesis, macroeconomic tailwinds — nuclear's re-emergence as the only baseload carbon-free source at scale, combined with record AI infrastructure power demand — have produced a structural uranium supply gap. The Mkuju Corridor is positioned at the intersection of all of these forces.

• Regional airborne radiometric and magnetic interpretation across all five licences
• 12-kilometre anomaly delineation at SWC-Mtonya from radiometric data
• Trench programme returning peak assays to 7,139 ppm U₃O₈ at surface
• Integration of historical auger geochemistry (peak 3,825 ppm U₃O₈) into a single structured database
• Baseline environmental and social scoping across the priority tenements

The next programme phase comprises detailed ground-radiometric follow-up across the remaining 9 km of the SWC-Mtonya anomaly not yet trenched; a maiden RC drill campaign of approximately 3,000 metres, targeting the trench intersections at depth to confirm roll-front geometry; auger and infill soil geochemistry on secondary targets across the broader 1,328 km² package; and initial scoping of ISR amenability (hydrogeology, aquifer characterisation, leachability testing) to support eventual development-track decisions.
