Arunta

The Arunta Project area is east of the Stuart Highway between Alice Springs and Tennant Creek near the township of Barrow Creek. The project comprises EL 23186 Barrow Creek covering ~90km2.

There are two key known prospects at Barrow Creek. These are the Home of Bullion mine and Prospect D. There are also other prospects within this project.

Home of Bullion

Base and precious metal prospects near Home of Bullion.

The Home of Bullion mine is a high-grade volcanogenic massive sulphide (VMS) style deposit developed in two main lodes. The Cu-Pb-Zn deposit includes:

– an Indicated Resource of 0.5 million tonnes averaging 2.8% Cu, 3.4% Zn, 56g/t Ag, 1.6% Pb, 0.30g/t Au; and
– an Inferred Resource of 2.0 million tonnes averaging 1.6% Cu, 1.7% Zn, 31g/t Ag, 1.0% Pb, and 0.11g/t Au.

The total Indicated and Inferred Mineral Resource estimate is 2.5 million tonnes averaging 1.8% Cu, 2.0% Zn, 36g/t Ag, 1.2% Pb and 0.14g/t Au.

Massive sulphide mineralisation at Home of Bullion is stratabound and hosted in the lower amphibolite facies Bullion Schist. The primary coarse-grained sulphide mineralisation is associated with magnetite and consists of pyrite, chalcopyrite, sphalerite, bornite, galena and minor chalcocite.

In addition to these two lodes, there is a series of prospects and anomalies along west north-westerly trending zones that can be recognised in the aeromagnetics and geochemical sampling data.

Prospect D

Geology of Prospect D

Prospect D contains copper-nickel mineralisation, which has been mapped over a length of 2km. A higher-grade zone has been traced for over 250 metres and remains largely untested at depth. The copper-nickel mineralisation has been described as a massive sulphide band with lower grade disseminated sulphide mineralisation in the footwall gabbroic rocks. The near surface oxide zone at Prospect D is known as Prospect DA may represent a potentially open pittable deposit.

Lithium Exploration

Pegmatite dykes have been mapped widely in the Arunta Complex and may occur in the Barrow Creek tenement. These pegmatites, which are related to granites, have potential for the discovery of lithium mineralisation associated with spodumene and other mineral species. No sampling and assaying nor any drilling activities have been carried out in the past for lithium.
