Gawler Craton and Curnamona Province SA
Pernatty Lagoon Project: Copper-Gold
This project is located 30 kilometres south of BHP’s large Carrapateena copper-gold deposit in the Gawler Craton and targets giant skarn style deposits where the regional IOCG mineral systems invade carbonate host rock types.
Recent three dimensional magnetic and gravity modelling has successfully imaged a previously unrecognised granite intrusion thought to be the local heat and potential metal source driving strong skarn alteration and copper mineralisation in this area. Integration of this deep modelling with the existing drill data has prioritised separate, previously untested, magnetic and gravity targets for drilling. Heritage surveying in preparation for drilling is planned.
Callabonna Project: Copper-Gold
Located along the northern margin of the Curnamona Province this frontier project targets several large magnetic and gravity targets for large IOCG breccia deposits.
Limited historic drill tests in the region have shown the existence of large IOCG breccia systems underlining the high potential of geophysical targets in this region. Three- dimensional modelling of magnetic and gravity data sets and passive seismic surveying has been utilised to prioritise key targets for drilling. Heritage surveying in preparation for potential drilling is planned.

Note the large low magnetic granite intrusion and the large untested magnetic target and gravity target near the wide zones of copper mineralisation in historic hole DD18PTH001 (refer Red Metal ASX announcement dated 11 April 2019). Historic hole PN-07-08 terminated above the magnetic target in strongly altered Gawler Range Volcanic (GRV) rocks (refer Red Metal ASX announcement dated 8 May 2007).
