Final Report 'Mt Riddock' 20 August 2013 to 14 August 2020 EL 29689

Abstract

This report details exploration activities completed within tenement EL 29689 'Mt Riddock' by Core Lithium Ltd (CXO) from 2013 to 2020. EL 29689 is comprised of 47 blocks located 110km northeast of Alice Springs. The area is dominated by parts of the Aileron and Irindina Provinces and their contact in the Central Arunta Region. The basement in the area consists of sedimentary and igneous rocks of the Aileron Province of Palaeo-Proterozoic age (1865-1500 Ma). The Aileron Province rocks mostly comprise of variably metamorphosed sediments, volcanics, calc-silicates, amphibolites and granite. The Proterozoic Aileron Province is recognised to be prospective for Cu-Au mineralization, possibly with iron oxide copper gold (IOCG) affinities, whilst the Neoproterozoic to Cambrian aged Irindina Province is a highly deformed and amphibolite to granulite grade metamorphosed province which has recently been found to be prospective for copper-nickel-cobalt. During the first years of this tenure CXO collected surface geochemistry, IP and VTEM datasets over Mt Riddock and completed RC drilling at Copper Royals and Virginia targeting copper mineralisation. In recent years of reporting, exploration activities in EL 29689 have been limited to office-based studies due to a substantial commitment of resources and funds by CXO to the Finniss Lithium Project area, proximal to Darwin. Following a review of CXO's exploration tenure holding in the NT the company has decided to relinquish this license so it can focus on progressing the Finnis Lithium Project.
