Annual Technical Report GR632/23 Mt Hardy Project EL 33368 and EL 33369 Group Annual Report for the period 21 June 2023 to 20 June 2024

Abstract

UROs Mt Hardy Project Area is situated ~300 km to the northwest of Alice Springs. The project area (located on Mount Doreen Pastoral Station) is located within the Aileron Provence which has extensive histories of uranium, vanadium, base-metal and more recently REE exploration. The Mount Hardy copper field lies within the Lander Group, where psammite and pelite have been metamorphosed into amphibolite-facies mica schist and andalusite porphyroblastic schist, exhibiting complex folding. Copper mineralisation is structurally controlled within quartz-veined shear zones, with surface mineralisation consisting of copper carbonates and gossans within sheared schists and brecciated quartz veins. The quartz veins range from tabular structures striking over tens to hundreds of meters to complexly fractured and folded stacks. The Mt Hardy copper field comprises a series of Cu-Au-Ag occurrences over a span of 25km2. Mineralisation comprises primary pyrite and chalcopyrite, with minor galena associated with quartz veins and pegmatite, within folded amphibolite-facies schist of the Lander Rock Formation. Geologically, the Mt Hardy Project area is characterised by a complex history spanning over 1.8 billion years. This region has been shaped by multiple geological events, including magmatism and orogenic processes, contributing to its mineral endowment which includes gold, copper, lead, zinc, tungsten, and uranium. The project area itself encompasses metasedimentary formations such as the Lander Rock Formation, intruded by significant granite bodies such as the Southwark Granite Suite. These granites are known for hosting minerals rich in tungsten, copper and rare earth elements (REEs), both within the granite itself and in the surrounding regolith. Initial exploration efforts by URO have focused on reconnaissance and data compilation, leveraging historic reports and geological data to identify prospective targets. Surface sampling and geological mapping have been conducted to assess mineralisation potential, particularly focusing on areas where previous exploration indicated anomalous copper and other base metal values. Anomalous Cu readings of up to 365ppm and 339ppm were analysed in surface samples of the Reynolds Range group metamorphosed sandstone, which both contained elevated Ni readings of 181ppm and 142ppm respectively. Future exploration plans include detailed geophysical surveys and further surface sampling to refine targets for drilling. The strategic approach aims to uncover the full potential of EL 33368 and EL 33369's mineral resources, particularly base metals and REE, supported by modern geological and geophysical techniques. This report outlines the groundwork completed in the initial phases of exploration, laying the foundation for subsequent detailed investigations and potential resource delineation in future phases of the Mt Hardy Exploration Project.
