Southern Cross Project


The Southern Cross project includes over 20 kilometres of prospective greenstone located at the northern end of the highly endowed Southern Cross Greenstone Belt. The belt is an Archean-aged and metamorphosed volcanic dominated package of mafic-ultramafic volcanic and sedimentary rocks. The belt is intruded by Achaean-aged granites, pegmatites and Proterozoic-aged dykes. Multiple deformation events have led to various shears, faults and folds through the belt, persisting into the project area.

The Southern Cross Greenstone Belt is considered highly prospective for gold mineralisation. There are numerous one million ounce plus gold deposits owned by third parties within the belt including Bounty, Yilgarn Star, Marvel Loch and Copper Head (Figure 7.0). The belt also contains the komatiite-hosted Forrestania Nickel deposits (owned by Western Areas Ltd) and the pegmatite hosted Mt Holland Lithium deposit (owned by Kidman Resources Ltd).


Gold prospectivity within the project is demonstrated by historical production at the historic Carterton gold mining centre (reported production of 8,552 oz at 30.5 g/t gold) in the southwest corner of the project area. The host structure of this mineralisation is present along the western boundary of the project. Historic soil and drilling programmes have been undertaken within the project. No exploration work has been undertaken for lithium mineralisation. Fractionated granitic intrusions as well as pegmatites have been noted in the project area but remain untested.


Due to the project being prospective for multiple commodities, it is proposed that baseline data sets be compiled and acquired including surface geochemistry and magnetic and radiometric geophysical imagery. An interpretation of the regolith and basement geology is planned to be produced with the assistance of historical drilling, outcrop mapping and various imagery sources. The interpretation would then allow a review of the effectiveness of the previous exploration through the project and a new exploration targeting exercise would be undertaken. Exploration targets would be reviewed and either geophysically tested or drill tested.
