PALTHRUBIE AND LAKE ACRAMAN- South Australia
The Palthrubie and Lake Acraman Projects are located in the prospective Gold Province of the Gawler Craton in South Australia (Figure 1). The primary target within the project has been high-grade “Tunkillia-style” gold mineralisation hosted within Hiltaba Suite granites which intrude the area.
Previous calcrete sampling has defined discrete gold anomalies at several prospects at Palthrubie including; Deep Well, Sisters East and Sisters West. Much of the project is covered by aeolian sands of the Moornaba Formation and soil sampling is thought to be largely ineffectual.
Limited aircore drilling at the Deep Well and Sisters West Prospects has returned shallow gold intersections up to 1g/t Au with a best result to date of 6m @ 1.002 g/t gold from 12m in drillhole JDAC035. Mineralisation is hosted by quartz veins within Hiltaba granite with associated strong sericite-pyrite alteration. Several gold-in-calcrete anomalies remain untested.
Recent work has also indicated the possibility of Uranium to be hosted in the palaeochannel which runs for 30km, east to west, through the middle of the project. The palaeochannel is flanked to the north and south by radiometric ‘hot’ granites (source rocks) and displays a number of subtle radiometric anomalies in association with salt lake development.
