An area located approximately 65 km south of Oodnadatta, on the Boorthanna Plain near Peake Creek, was taken up to explore for iron oxide copper gold (IOCG) or similar style mineralisation which might be hosted by basement Proterozoic rocks on the margin of an interpreted granite intrusion. This inferred igneous body was thought to be concealed beneath approximately 100 m thickness of Mesozoic and younger sedimentary cover sequences. Basement geology in the area was not well understood owing to the complete lack of outcrop there and scant drillhole data. Matthew Hutchens recognised the untested potential of the area through his analysis of public domain regional gravity data produced by the 2008 PACE Northern Olympic Domain Gravity Survey. During licence Year 1, work completed included a desktop review of all available previous exploration data, plus the acquisition of a new detailed infill ground gravity survey over the Nilpinna anomaly, and the collection of new petrophysical data for limited bottomhole drill core competent rock samples, as measured from three existing historic BHP drillholes located in the vicinity of the prospect. The gravity survey was read by contractor Daishsat during February 2014 over a 50 m x 200 m grid, for a total of 990 stations. Data processing disclosed a 2 mGal central gravity high superimposed on a wider, U-shaped ~4 mGal gravity high, the overall anomaly being positioned close to the interpreted position of the G2 crustal lineament. Inspection of the best quality regional aeromagnetic data (BHP's 83SA05 survey dataset) revealed a generally subtle magnetic signature in the prospect area, with one small, ~500 nT discrete circular anomaly present on the NW edge of the main gravity anomaly. Alteration of the downhole basement rock mineral assemblages seen in historic drillholes NC1 and NC3 was regarded as possibly being the product of hydrothermal alteration caused by the inferred granite pluton, as well as having resulted from retrograde metamorphism. During licence Year 2, Hutchens performed desktop studies and additional geophysical data processing and modelling to refine the definition of the exploration target at Barney Bore and to establish the best locations for drill testing. Meetings were held with prospective joint venture partners during the year, which culminated in the signing of a JV agreement with Kingston Resources Limited on 12/7/2015. During licence Year 3, Kingston Resources contracted an independent consultant to prepare a geophysical data modelling report and geological data summary for the Barney Bore prospect, as part of a project-wide, four licence IOCG prospectivity assessment. Terra Resources found that the Barney Bore target has the largest amplitude gravity anomaly of any prospect within Kingston Resources' entire Cootanarina Project, and ranked it the primary target for IOCG exploration. Their 3D inversion geophysical modelling results agreed with Hutchen's earlier work, predicting a vertical pipe-like body as a source of the gravity anomaly. Preparations were made to conduct drilling on EL 5309, with a PEPR written and submitted to DSD for approval, and a field undertaken trip to visit landholders and to peg the proposed drillhole location. Late in 2016, Kingston Resources underwent a corporate restructure, which saw the company move away from copper as a focus of exploration, making the task of identification of the Barney Bore drilling target surplus to requirements. After management of the licence reverted to Matthew Hutchens, he continued to study all of the geophysical data relating to the Barney Bore prospect. Late in 2016, he undertook some inversion modelling of Red Metal's 2007 airborne EM (RepTEM) survey data, 73.5 line km of which had been flown over what is now EL 5309. Line 1455 of that survey had crossed the centre of the Barney Bore gravity anomaly. However, a CDI image which he created for the AEM data recorded on that line did not show that an obvious conductor is present there. During 2017, Matthew analysed the gridded 1983 BHP Minerals aeromagnetic data for Barney Bore prospect for the magnetism's principal component, using a data visualisation method called the Normalised Source Strength (nss), to serve as a comparison with the standard reduced to pole (rtp) image. There seemed to be a large difference between the rtp and nss images, suggesting that there is likely to be strong magnetic remanence associated with the local magnetic sources. In March 2018, a decision was made to surrender the licence.
