An area located immediately south-west and south of Lake Blanche has been explored for possible economic sedimentary roll front style or calcrete-hosted uranium deposits, that may have formed within Quaternary fluvial channel fill sediments in proximity to some exposed radiogenic portions of the Proterozoic Curnamona Craton basement. The nearest eroding potential uranium source rocks lie ~40 km away to the south. During the first licence year, Red Metal's activities comprised: • compiling historic uranium exploration data and regional airborne radiometric survey data; • conducting a field reconnaissance to assist with planning the logistics of drill traverses; • obtaining work area clearances through negotiation with Native Title claimants; and • scout drilling of 37 shallow vertical aircore exploratory holes in May-June 2006 for a total penetration of 1115 m, to assess the potential for Quaternary calcrete-hosted uranium to occur in fluvial palaeodrainage channels underlying contemporary stream systems. The recovered drill cuttings were scanned at surface with a scintillometer, but no anomalous radioactivity was detected. 164 selected cuttings samples were submitted for laboratory assaying of selected trace elements, but no significant results were returned. During licence Year 2, Red Metal acquired part of a multi-licence airborne EM survey over EL 3471 in November 2007, when 450 line km were flown along eight NW-SE orientated flight lines spaced 2 km apart, using a 30 m mean terrain clearance. During licence Year 3, Red Metal processed and interpreted the new AEM data to aid in selection of locations for test drilling of the Tertiary sedimentary sequence. During licence Year 4, Red Metal drilled and geophysically logged 15 widely spaced vertical rotary mud holes for 2536 m in August-September 2009, targeting the Eyre Formation for its uranium potential and sediment redox state. No radiometric anomalies were detected on the gamma ray logs, and observations of the drill cuttings indicated that the Eyre Formation is predominantly reduced in the places tested, which were chosen to be proximal to inferred basement-penetrating faults. Following the entry of Cameco Australia to the exploration programme in June 2010, that company reviewed the available geological data and made a field reconnaissance trip to plan further drilling activity which would be directed in part at evaluating Namba Formation units which could possibly be equivalent to the Beverley deposit host strata. Ensuing wet ground conditions caused a postponement of the start of the planned drilling campaign. Later on, Cameco decided to withdraw from the Lake North JV midway through licence Year 7, after having drilled 43 exploratory vertical rotary mud holes on renewed EL 4621 without finding economic uranium mineralisation [see related Env 12230 for a final report prepared by Cameco describing these drilling results]. Licence management reverted to Red Metal, who reviewed Cameco's drilling results to try to better interpret the distribution of the Tertiary sediments' redox transition zone, whilst also beginning a search for a new exploration JV partner. No field work was conducted during licence Year 8, before a decision was made to allow tenure to lapse.
