This report documents the construction for MESA of a technical database on the potential for undiscovered Triassic coal within small intermontane basins of the north-central Flinders Ranges region, addressing all alluvium-covered areas that lie within a corridor extending for 50 km either side of the railway line from Marree to Port Augusta. Any target(s) to be selected for later testing by gravity surveys and/or drilling had to meet MESA's economic constraints on size of deposit and thickness of overburden: the minimum size prospective area was to be equal to that of the Leigh Creek Lobe 'D' deposit (i.e. approximately 2x3 km), and the maximum overburden thickness (to allow dragline mining) was estimated at 30 metres (based on the Lobe 'D' model). The project Phase 1 brief was for a contractor to review existing geological, geophysical (gravity) and drilling data for the area, and extract and summarise any information considered relevant to such aims. A total of 220 company Exploration Licence histories and 1550 water bore records were reviewed, and the resulting information is presented as a series of tables and plans organised around a Sheet 1/Sheet 2 split of the region of investigation, to areas north and south of Parachilna. From study of both areas, the preliminary conclusions are that previous exploration has been insufficient to eliminate the possibility of existence of additional concealed Triassic coal basins.
