The Kangaroo Dam exploration licence 3445 covers the western portion of the Palaeoproterozoic Mount Woods Inlier, a large block of variable magnetic intensity lying to the east and south-east of the Coober Pedy Ridge and the Mabel Creek Inlier. These three terranes abut an interpreted Archaean age cratonic area to their south and west. The area contains major regional structures (including the Karari Fault Zone) and is traversed by several prominent north-westwards trending structures along which significant thicknesses of Permian sediments have been deposited. Basement outcrop in the region is generally restricted to a quarry outcrop in the south-west of the tenement, and there are limited exposures of Gawler Range Volcanics and Archaean gneisses further away to the south and south-west of the EL 3445 area. From 2001 to 2003 the precursor licence, EL 2760, was part of the Mount Woods Joint Venture formed between the tenement holder, Goldstream Mining NL (now IMX Resources Ltd), and project operator, Anglo American Exploration (Australia) Pty Ltd (Anglo). Fieldwork under the joint venture commenced in late 2001. Initial exploration by Anglo involved a comprehensive review and compilation of previous work which identified the potential of the area for hosting craton-margin magmatic nickel deposits, besides recognising the presence of a number of aeromagnetic and gravity targets having potential for IOCG style mineralisation. Aboriginal cultural heritage clearance surveys were completed to allow the conduct of a ground gravity survey (at 200 m x 800 m and 200 m x 1600 m station spacing) and soil sampling (on 400 m x 400 m and 400 m x 1600 m grids). However, the results of its geophysical and geochemical surveys were considered by Anglo to downgrade the potential for finding an economic IOCG deposit, and the company subsequently withdrew from the joint venture. Management of the licence was returned to Goldstream. In 2004, Ian Garsed of Garsed & Associates was contracted by Goldstream to conduct a detailed assessment of exploration conducted over the entire Mt Woods Project licences which included the Kangaroo Dam area. Five geophysical targets were identified here using gravity grids and interpreted geology. The licence subarea now being relinquished has been covered by part of the October 2002 gravity survey, which had stations spaced at 400 m intervals on N-S lines spaced 1600 m apart. Locally there are some intermediate lines. Data is presented with the subject report for these 61 gravity stations. Presently, in the remainder of EL 3445, modelling of gravity and magnetic data and re-interpretation of the existing exploration data is ongoing, in order to determine depths and geometry of possible IOCG mineralised targets. Several targets have lately been drilled.
