Annual and Final Report EL 32839 06 April 2024 to 09 May 2025

Abstract

Exploration Licence (EL) 32839 is located approximately 150 km to the north of Tennant Creek and approximately 15 km to the east of the Stuart Highway. The EL was granted on 6 April 2022 for a period of 6 years expiring 5 April 2028. EL 32839 was originally obtained to explore for manganese due to prior exploration and geological similarities to the Bootu Creek Mine. Literature research however, revealed that adequate drilling had been carried out and the potential for economic deposits of manganese mineralisation was low. Consequently, the potential for non-manganese mineralisation within the EL was investigated. Mining at the Bootu Creek Mine exposed oxide copper mineralisation within the upper Attack Creek Formation. Other zones of copper mineralisation are reported in the region including a hypogene copper occurrence in an area southwest of Banka Banka Station, possibly related to splay faults (Simpson 2000). Together, these copper occurrences indicate that the general region may be prospective for copper mineralisation, especially in the upper parts of the Attack Creek Formation. Areas within the EL were identified which should have Attack Creek Formation at or the near surface. The current 1:250 000 Helen Springs Geological Map depicts a small outcrop of Attack Creek Formation in the core of a shallow anticline in the centre of the EL. If confirmed, this would indicate a large extent of prospective Attack Creek Formation at shallow depths. A review of existing data was carried out in year 1 and soil sampling of selected geophysical anomalies was undertaken in year 2. It was decided at the end of year 3 that results obtained to date did not warrant follow up, and the EL was relinquished on 9 May 2025. There is no data to submit with this report.
