Charley Creek South-East Project Partial Relinquishment Report EL 33006 09 August 2022 to 22 August 2024

Abstract

Exploration License (EL) 33006, located approximately 65 km northwest of Alice Springs, lies within the mineral-rich Arunta Region, extending across Amburla and Hamilton Downs Stations pastoral lands. The tenement features an extensive alluvial plain north of the MacDonnell Range foothills, characterised by coarse gravels, sand, silt, and clay, interspersed with aeolian quartz sand. Isolated outcrops and sub-crops of the Adla Granulite Formation, with localised ferricrete, calcrete, and lateritic gravels dot the landscape. The relinquished portion of EL 33006 is prospective for base metals, rare earth elements (REEs), uranium, and polymetallic deposits. Multiple deposit styles were considered, including sediment-hosted uranium, palaeochannel-related uranium, felsic intrusion-related REEs, mafic intrusion-related base and precious metals, and polymetallic metamorphic-related deposits. However, the area remains relatively untested due to logistical challenges, including dense vegetation. During its tenure, URO Corporation conducted desktop studies, field sampling, and data analysis to assess the region's mineral potential. A total of 98 surface samples, including soils and rocks, were collected and analysed using portable pXRF and scintillometers. Although no significant geochemical anomalies were identified, several isolated pXRF readings suggested elevated levels of rare earth elements such as Ce, La, and Nd, warranting further exploration in the surrounding areas. In response to rising costs and strategic prioritisation, URO has relinquished the western portion of EL 33006 to concentrate resources on more accessible and prospective areas. Nonetheless, the tenement remains highly prospective for sediment-hosted uranium and REEs, with deeper crystalline basement rocks beneath the regolith and sedimentary cover holding potential for polymetallic deposits. URO Corporation's exploration activities have provided valuable insights that will guide future exploration efforts in adjacent areas.
