Central Australia Minerals Project GR610 EL 31378 Surrender Report and Annual Report for the Period 11 November 2024 to 03 October 2025

Abstract

EL 31378 is part of the GR 610 Central Australia Minerals Project that comprises 13 contiguous Exploration Licences of 2,432 sub-blocks, located over the Eastern Musgraves Province - Pedirka Basin on the Northern Territory - South Australia border. This Final Surrender Report summarises all the work completed by Tri-Star over the tenure and the rationale under the surrender of the exploration license. The Project incorporates licences from three separate groups: Western Leases (ELs 32716, 32717, 32718 and 32719, granted 11 November 2021), Central Leases (ELs 32644, 32645, 32646 and 32647, granted 21st September 2021) and Eastern Leases (ELs 31358, 31371, 31375, 31376 and 31378, granted 1st November 2017). Coal in the Pedirka Basin was the previous focus of work on the older Eastern Leases, however, Tri-Star Group explored the continuation of the Eastern Musgraves Province beneath the Pedirka Basin for orthomagmatic Ni-Cu-PGEs, alkali/ carbonatite-hosted REEs, diamond-bearing kimberlites, IOCG style Cu-Au, and intrusion related gold systems. This report outlines the work carried out over EL 31378 and the Central Australia GR 610, as well as the reasons for its surrender.
