An area centred 40 km west of Kimba has been explored initially for basement gold and nickel mineralisation, and following a joint venture, for possible IOCG and palaeochannel uranium mineralisation. During the first year of tenure, reconnaissance calcrete (34 samples) and rock chip (10 samples) sampling of four areas with underlying major structural features in the basement was undertaken during October 2007 on the recommendation of a geological consultant. Slightly elevated gold values, to a maximum of 5 ppb Au, were obtained near Kyimba [correct spelling] along a north-south trending linear magnetic trend. After Southern Uranium farmed into the subject EL 3644 in early 2008 and became exploration operator, its subsidiary Investigator Resources carried out a programme of regional and infill soil geochemical sampling (Euro Exploration Services, November-December 2008, with follow-up in 2009 and 2010) and regional gravity data acquisition on a 1 km x 1 km grid spacing (Daishsat Geodetic Surveyors, August-September 2008). [Because this work was jointly reported with that similar being carried out on EL 3645 Kimba, a tenement which is still being held at the date of the subject data release, only the basic data relating to those activities is being released to the public herein. Therefore, the assay results for 1142 soil samples, and the gravity data for 565 stations read on EL 3644, are included in the subject Envelope. In addition, a small subset of the gravity survey data relating to EL 3645 was previously released in January 2014, upon a partial relinquishment of the Kimba tenement acreage, and is stored separately in Env 12512]. Apart from the acquisition of 9410 ground magnetic readings (AsIs International, September 2009) along traverses made in the western part of the licence area across the Kyimba trend, which is one of Stockdale Exploration's historically reported aeromagnetic anomalies that may have potential to denote discrete small igneous intrusions (e.g. kimberlite/carbonatite, or more probably, small basic/ultramafic plugs and dykes), no further field work was undertaken on EL 3644/4937 Caralue before the decision was taken late in 2013 to allow tenure to lapse because of perceived diminished prospectivity and competing exploration priorities, plus the ongoing difficulties of having timely or indeed any consentual access allowed by landowners onto many plots of freehold agricultural farmland.
