Moodong Well


The Moodong Well prospect is located within the Ashburton Mineral Field near Nanutarra and is about 1,250 kilometres north of Perth. The tenement covers an area of mineral claims once held by Afmeco Pty Ltd, who carried out a uranium exploration program in 1974-75. Afmeco reported a suite of pelitic sediments with some calcareous units, metamorphosed to upper greenschist to granulite facies. This sequence is intruded by granitoids and unconformably overlain by Middle Proterozoic sandstones of the Bangemall Group.


Several anomalous environments were identified by past work.


  • Hematite, magnetite and gossanous veins containing minor barite and malachite had best assays of 1300 ppm uranium, 1.5% copper and 800 ppm lead;
  • Silicified shear zones had a best assay of 880 ppm uranium;
  • Sheared, weathered ferruginised rocks with up to 140 ppm uranium;
  • Mineralized mafic rocks in pegmatite gave 470 ppm uranium and 240 ppm copper.

Exploration investigation and field work in 2007 included a regional geological review and reconnaissance survey targeting Uranium and Copper mineralisation within the prospect plus interpretation of existing regional mapping, highlighted structural trends and wide spaced radiometric imagery. In total, 60 rock chip samples were collected and assayed for Barium (Ba), Uranium (U), Thorium (Th), Potassium (K), Copper (Cu), Lead (Pb) and Zinc (Zn) with no significant or anomalous results being returned from the surface exposures. As previously reported, the tenement has significant areas of colluvial cover which may mask obvious signs of mineralisation.


As geological mapping indicates that the tenement displays significant areas of colluvial cover, the Company has acquired and reprocessed aeromagnetic and additional radiometric data as the next step in its exploration program for the Moodong Well Prospect. Interpretation of this data is under way.
