A small licence area located ~30 km north of Cockburn has been being explored for possible economic shallowly buried sedimentary roll front style uranium mineralisation that may have formed within inferred Tertiary fluvial channel sands of the Yarramba Palaeochannel system. The thin cover sediments in this area are underlain by undifferentiated Palaeoproterozoic granites and metamorphic schists which are exposed at surface nearby to the west. The large Honeymoon roll front sedimentary uranium deposit, hosted by Eocene Eyre Formation sands, is located further downstream in the Yarramba Palaeochannel system, ~20 km north-west of EL 3910. During licence Year 1, exploration operator Marmota Energy performed this work: 1) acquired a ground gravity survey of 445 stations, completed in early May 2008 by contractor Atlas Geophysics using quad bikes as transport. The gravity stations were read over a 200 m x 200 m regular grid which covered the entire tenement. 2) made a data compilation of historical exploration within the region of the tenement. The detailed gravity data from the survey clearly delineated an extension of previous interpretations of an upstream channel section within the Yarramba Palaeochannel system. Work conducted during licence Year 2 included: • Soil geochemical sampling survey on a 500 m x 500 m regular grid over a proposed drilling area on part of the tenement (27 samples) • Vegetation biogeochemical survey over a proposed drilling area on part of the tenement (30 samples of Casuarina bushes) • Geochemical analyses of soil and plant samples for uranium and pathfinder trace elements plus rare earth elements • An aboriginal heritage clearance survey made with a member of the Kuyani people • A 24 hole exploratory rotary mud drilling campaign with a total penetration of 2539 m, testing parts of the Yarramba Palaeochannel system • Geochemical analysis of selected samples of interest recovered from the drilling campaign • Rehabilitation of all drill sites and access tracks. No anomalous uranium was detected by the surface sampling methods. The drilling of interpreted geologically prospective parts of the palaeochannel encountered minor uranium mineralisation as indicated by readings on downhole wireline geophysical logs (gamma ray-SP-resistivity). Calibrated gamma ray logs from 12 of the 24 logged drillholes showed above background readings of between 50 and 100 ppm eU3O8, and another 6 holes had peak logged grades of over 100 ppm eU3O8. A composite 2-metre drill cuttings sand sample recovered from the log anomalous depth interval 88-90 m in hole MURM0110, which was analysed twice for a check of results, gave the highest laboratory assay uranium values of 46.9 and 43.3 ppm U. During licence Year 3, another 2 vertical rotary mud exploratory holes were completed for 215 m to test the better mineralised parts of the Yarramba channel on EL 3910. Again only minor anomalous gamma ray log readings were obtained, the highest being 142.2 ppm eU3O8 from a depth of 95.6 m in hole MURM0201. No assaying was done on any of the returned 2-metre drill cuttings samples due to the log-indicated low tenor of mineralisation. No more field work took place on the subject tenement during any of licence Years 4 through 10, and tenure was allowed to lapse in August 2017.
