Copper and gold exploration has been conducted within an area centred about 80 km east of Hawker, which it was thought had potential for epigenetic vein style mineralisation within buried Adelaidean sandstone and shale strata, formed in a stratabound setting that is probably related to a blind igneous intrusion or to salt diapirism. Shows of structurally controlled secondary copper mineralisation are widespread, and have been mined historically in many small scale surface workings. The area lies on the northern margin of the Nackara Arc, a tectonic subdivision within the Adelaide Geosyncline which forms an arcuate fold belt, concave towards the south-east, and containing strata comprised mostly of deeper water facies sediments. Folds are broad and upright, with axial plane slatey cleavage. Burra Group rocks usually occupy the cores of anticlines and Wilpena Group rocks the cores of synclines. Arenaceous units of the intervening Umberatana Group commonly host auriferous quartz veins, which are typically associated with structures such as anticlinal hinges or major northwest trending lineaments. EL 3946 covers part of the Bibliando Dome, which forms a major ENE trending anticline of low grade greenschist facies sedimentary strata. Regional aeromagnetic data indicate that a ridge of relatively shallow basement underlays the dome, forming the south-western edge of the Curnamona Craton. This highly magnetic ridge has long been thought to either represent an intrusive mafic igneous sequence lying at the base of the Adelaidean, or else a younger similarly magnetic intrusion that has penetrated into the Adelaidean, or alternatively, it might denote a region of intense iron metasomatic alteration in the basement. The current phase of exploration was guided by the locations of interpreted geophysical anomalies which appeared likely to have sources lying at relatively shallow depths, with the main aim being to define possible extensions of the historically worked Baratta copper lodes. During the first licence year, Redmile Resources' field work consisted of doing reconnaissance geological mapping, especially of previously described diapiric breccia and fault breccia zones, as well as taking limited grab samples of mineralised veins (10 samples). Surface geochemical sampling of soils was undertaken using a handheld portable XRF spectrometer, with 515 spot analyses made at 100 m intervals along traverses crossing the Windowarta and Baratta Spring diapirs. The mapping indicated that the Baratta copper deposit is hosted by a 1 m wide, flat dipping quartz-haematite gossan which outcrops semi-continuously over ~1.5 km of strike. Earlier mining had used shallow shafts and drives to attempt to access high-grade zones of secondary copper mineralisation present in the gossan. During the second licence year, work entailed the acquisition and interpretation of remote sensing data commissioned from consultants Earthscan, the focus being to identify major structures and any associated rock alteration. Further portable XRF soil sampling was done in the northern part of the licence (1019 samples analysed). Elevated contents of copper and cobalt (to 1870 ppm Cu and 6565 ppm Co) were indicated within altered siltstones and sandstones of the Wilyerpa Formation. During licence Year 3, new licensee Panda Mining acquired detailed airborne magnetic and radiometric survey data across the Baratta region to try to better constrain a previous estimate of the average depth to pre-Adelaidean basement of around 1.5 km. In May 2010, this survey was flown by GPX along north-south flight lines spaced 100 m apart with a 45 m nominal terrain clearance, for a total coverage of 3384.5 line km which included both EL 3946 and the project's adjoining EL 4247. Interpretation of the new geophysical data by David Isles identified three possible targets situated in the southern part of EL 3946, where faulted Adelaidean strata coincide with remote infrared spectral anomalies suggesting local hydrothermal alteration along the contact margins of the attenuated northern part of the Bibliando Diapir. During licence Years 4 to 6, Panda Mining conducted geological mapping, and geochemical rock chip sampling for laboratory assay, of breccias and gossans that it encountered during traverses made at 200 m intervals across this domed southern part of the licence area. No significant copper or other metallic mineralisation was found (e.g. on average ~0.3% Cu and ~20 ppb Au), but in some places anomalous values of K, P, Ba, Mn and Rb were recorded. The company noted its impression that certain rock textures and mineralogical features that it examined there in the field could have valid genetic affinities with the passage of heated brines and gases emanating from a possible buried carbonatite intrusive body. During licence Year 7, three rock chip samples were collected to follow up previously obtained anomalous antimony results in the laboratory assaying. These anomalies were not confirmed, however, with <60 ppm Sb being returned. In April 2014, a gradient IP survey was run across the Baratta mining field, for a total coverage of ~ 33 square km employing arrays read on a 40 m x 200 m grid. The survey results were largely inconclusive. No work was performed during the last year of tenure, before a decision was made to surrender the tenement.
