Charley Creek South Project Partial Relinquishment Report EL 33054 05 August 2022 to 22 August 2024

Abstract

Exploration License EL 33054, located approximately 125 km west-northwest of Alice Springs, spans Narwietooma Station and portions of Amburla and Hamilton Downs Stations. Access to the project area is facilitated by the Alice Springs airport, railway, and key transport routes such as the Stuart Highway, Tanami Road, and Kintore Road, with additional entry points via Narwietooma Homestead. Secondary roads and station tracks provide further access to various exploration zones within the tenement. The tenement is characterized by diverse terrain, including rugged hills and foothills-such as Mount Chapple and Redbank Hill-and alluvial plains covered with mulga, gum trees, spinifex, and termite mounds. Geologically, the area features Paleoproterozoic metamorphic rocks, notably the Narwietooma Metamorphic Complex, which includes mafic-felsic granulites and gneisses, along with outcrops of the Mount Zeil Granite and Forty-Five Augen Gneiss. Thick Tertiary sediments and Quaternary alluvium overlie portions of the tenement, concealing prospective basement geology. EL 33054 sits within the Aileron and Warumpi Provinces of the Arunta Region, with sections extending into the Ngalia and Amadeus Basins. This complex geological setting supports potential mineral systems for base metals, precious metals, rare earth elements (REEs), and uranium. Multiple deposit styles were considered, including IOCG-U, felsic intrusion-related uranium and REEs, palaeochannel uranium, mafic intrusion-related nickel and copper, and polymetallic metamorphic deposits. Exploration efforts by URO Corporation included desktop studies, field sampling, and data analysis. Initial campaigns were hindered by terrain challenges, such as dense vegetation and mountainous areas, leading to adjustments in field methodologies. Despite the collection and analysis of 95 surface samples - comprising soils and rocks analysed with portable XRF and scintillometers, and laboratory assays for select samples - no significant geochemical anomalies were detected for the target commodities. Large portions of the tenement overlap Northern Territory Aboriginal Sacred Sites, designated by the Aboriginal Areas Protection Authority (AAPA) as Restricted Work Areas or Recorded Sacred Sites. These restrictions rendered further exploration impractical in the relinquished areas. Consequently, these sections were surrendered, while URO continues to recognize the region's potential for REEs, uranium, and polymetallic deposits. The relinquishment decision reflects a strategic focus on more accessible and higher-priority exploration targets. Future work in retained areas will aim to build on regional datasets and refine exploration models for discovery.
