Two small adjacent licence areas on the plains near the south-eastern corner of Lake Frome, which were centred ~150 km north-northwest of Olary, have been explored for possible buried Tertiary palaeochannel or sheet sandstone-hosted, roll-front style sedimentary uranium mineralisation. Originally both areas, which also lie over the western edge of the Benagerie Ridge uplifted Proterozoic basement block, were acquired following a regional scale generative exercise that had sought vacant areas with potential for hosting buried Cu-Au-U-REE mineralisation. The Coombs Spring area was taken up first, in late 2006, when all public domain and previous explorers’ geophysical data were reviewed, reprocessed, assessed and interpreted by Southern Geoscience Consultants of Perth, and a compilation of available open-file geological reports was carried out by B. Tavcar of Carbon Energy. From this work it was determined that the source depths of IOCG - prospective magnetic/gravity anomalies had been estimated by several of the previous explorers to be from several hundreds of metres to >1500 m below the surface, a factor that obviously made them less attractive for the company to contemplate for drill testing. Attention then became switched towards the more accessible and inferred uranium prospective Cainozoic palaeodrainage known to be present in this area, that might connect to a known occurrence of sedimentary uranium mineralisation at Gould’s Dam located ~45 km to the south. During the first year of project licences' joint reporting, no field work was done. The licensee undertook desktop review of past exploration data, including re-interpreting available gravity data, to try to discern any northwards extension of the Billeroo Palaeochannel. It was interpreted that such an extension does exist, based on inferences drawn from open file geology, geophysics and satellite images. A partial relinquishment of 31.6% of the grant area of EL 3651 was made on 22/11/2008. During the second year of the project, because of budgetary constraints, and pending the divestment of the tenements to new company Energia, no field work was undertaken. Following the conduct of a review of previous geophysical surveys by Southern Geoscience Consultants, acquisition of a detailed ground gravity survey on both licences was planned. Its aim was to locate palaeochannels for drill testing, and to assess whether any coincident magnetic-gravity anomalies lay at economically feasible depths. During the third year of the project, a ground gravity survey totalling 735 stations was read during July-August 2010 along four east-west lines spaced 2 km apart using 100 m station intervals. 208 stations were read on EL 3651, and 527 stations on EL 4035. The new gravity data were interpreted by Southern Geoscience Consultants to have defined two main buried channel features running down the eastern side of the surveyed area, plus sections of subordinate channels heading in from its western side. The trends of these features coincide with known palaeo- and modern drainage directions. Early in the year, new project owner Energia Minerals retained consultant David Tonkin to review all open file geological data and earlier licence exploration activity as part of the tenement transfer. He confirmed the prospectivity of both ELs for roll-front-type uranium mineralisation, given the interpreted continuation onto the tenements of the Billeroo Palaeochannel which some 35 km to the south hosts the Gould’s Dam deposit. The potential for basement-hosted Cu-Au deposits was also identified, because the Portia and White Dam prospects are located respectively 45 km and 115 km to the south-east. The nearest hole to the project licences that had reached prospective basement was believed to be LNM10_1, drilled by Mines Administration in 1982 and located about 6 km to the east, which had encountered Benagerie Volcanics at 231 m depth. During the fourth year of the project, Southern Geoscience Consultants performed geophysical modelling of a coincident gravity anomaly/magnetic high located near the centre of EL 4035. But the results were ambiguous, mainly owing to minimal geological information. Drill testing or the acquisition of additional gravity data was recommended. An Information Memorandum for all of Energia's SA mineral exploration projects was completed, and parties likely to be interested in entering into a joint venture agreement were approached. Late in 2011, Energia became aware that the large regional dataset from Geoscience Australia's 2010 Frome Embayment Aerial EM (TEMPEST) Survey had been processed and was publically available, so the company acquired and evaluated that data which had been derived over its project ground in order to further plot palaeochannel distribution. The data came from seven flight lines spaced 2.5 km apart. During the fifth year of the project, no field work as done. Energia was unable to attract any JV interest in its Information Memorandum, and its further examination of all available geophysical data did not reveal high priority targets for drilling. During the sixth year of the project, no field work was done. Energia commissioned geophysicist Anne Tomlinson of Southern Geoscience Consultants to review and interpret the Frome Embayment AEM Survey data, and she found that the northern extension of the Billeroo Palaeochannel definitely exists within the eastern part of the project area, as a wide main channel with a lesser channel running sub-parallel to it further west. Several target zones along it with sedimentary uranium potential were identified. It was recommended to conduct another, higher resolution infill AEM survey over them using a higher powered acquisition system such as SkyTEM, and to fly much closer-spaced lines, of at least ~400 m apart, firstly to allow for better signal penetration beneath conductive near-surface sediment layers, and secondly to much improve the definition of channel tributary responses and perhaps pinpoint their prospective junctions. However, due to continuing fiscal constraints, and the perceived excessive risk still attached to drilling either uranium or IOCG targets identified there, Energia made the decision to focus its efforts elsewhere within its then current tenure than the Coombs Springs Project, and both licences were fully surrendered at year end.
