(6 Tenements – 6 Granted)
Aurora’s Doolgunna Project consists of 6 granted exploration licences covering a 900km2 area along the northeastern edge of the Early Proterozoic Yerrida Basin where it is overlapped by younger sediments of the Earaheedy Basin of Early-Mid Proterozoic age. The edge is marked by a series of parallel NNW to NW trending structures, considered by Aurora to be a southeastrly continuation of the regional Mt Clere Fault, believed to have focussed gold and base metal mineralisation at the Peak Hill, Thaduna and Doolgunna Districts immediately to the north.
The Yerrida Basin hosts lead mineralisation at the Magellan Lead Mine to the south, and the Earaheedy Baisin contains stratabound zinc-lead mineralisation to the east of Doolgunna.
Previous explorers sought base metal mineralisation in the lower units of the Earaheedy sedimentary sequence and outlined several surface anomalies of up to 922ppm Cu and 400ppm Zn in rock-chips and 640ppm Cu and 1400ppm Zn in limited RAB drilling within Aurora’s Doolgunna project.
Aurora is planning a 5500 line km Mag-Rad survey to better understand the structural setting of these anomalies and identify targets for follow-up ground geochemical and prospecting activities.
