A north-south elongated, narrow licence area centred ~30 km north of Whyalla and covering ground inland adjacent to the Lincoln Highway, has been taken up to explore for possible economic buried stratiform/stratabound, Mississippi Valley type syngenetic base metal deposits that may have formed in receptive Neoproterozoic metasediments that were deposited in a deep, fault-bounded trough next to the western edge of the Mesoproterozoic Cultana Inlier. The licensees' attention has been directed towards assessing the known historic Myall Creek copper deposit (discovered by Australian Selection and Sims Metals in March 1975) which consists of disseminated low grade Cu–Zn–Pb-Ag sulphide mineralisation (typically 0.3–0.5% Cu) extending over a poorly defined area of ~3 km x 15 km as recorded by past broad-spaced drilling. A zone of ~3 square km extent containing higher grade copper, up to 2.2% Cu, lies within the low grade mineralised envelope. The known mineralisation occurs in a thin (0.5–2 m) sedimentary horizon at the base of the Late Proterozoic Tapley Hill Formation, at a variable and structurally controlled depth of 50–200 m. During licence Year 5 to 21st February 2006, Minotaur's technical re-assessment of the available Myall Creek data indicated that although the mineralisation tenor is variable, there might be potential to increase the deposit's overall grade and tonnage by undertaking exploration works targeting the high grade mineralised horizon. The acquisition of an orientation IP survey along two east-west lines each 2 km long was proposed, to try to delineate this horizon and to appraise its possible extension eastwards into formerly poorly explored country. During project Year 6 to 18th April 2007, and the first annual report for EL 3538, in the 2006-2007 period, the planned dipole-dipole IP survey program was undertaken for a total of 20.3 line km and 1671 data points, eventually comprising the aforesaid 1 km x 2 km test coverage at 400 m line spacing read during March 2006, plus 8 additional infill lines spaced 100 m apart that were read during August 2006. The initial test showed that although the mineralisation did not produce outstanding primary anomalies, inversion of the IP data gave results that seemed to have effectively mapped the depth to the top of the mineralisation. The more detailed IP infill coverage defined a number of semicontinuous highly chargeable bodies, some of which seemed to correspond with the known copper mineralisation found by historic drilling. Eleven prioritised targets were selected for test drilling. During project Year 7 to the 18th April 2008, between May-June 2007, as part of a PACE Initiative - subsidised drilling project, 4 vertical RC holes with a total penetration of 529.9 m (where 83.9 m of diamond tail coring was conducted in 2 holes) were drilled at ~200 m collar spacing along IP Line 6373150mN, but they showed that the chargeable IP anomalies detected there reflect the abundance of pyrite rather than copper-bearing sulphides such as bornite and chalcopyrite [see Env 11446 for the full final report on PACE collaborative drilling Year 4 partnership no. DPY4-47]. Due to this disappointing result, Minotaur Resources quickly decided to sell its interest in the tenement. A conditional Sale and Purchase Agreement which it subsequently made with U Energy Pty Ltd was executed in February 2008. No further work was performed during the period 2008 to 2011 (licence Years 8-10), while the new exploration operator and its JV partner reviewed the tenement data and resolved to change exploration focus to searching for possible buried IOCG type mineralisation that might be hosted by crystalline basement rocks. A study of recent seismic data for the Myall Creek area concluded that major normal faults which were active during the Mesoproterozoic and Neoproterozoic had reversed their movements during the Delamerian Orogeny, forming several horst structures. Interpretation of the structural fabric evident in the tenement area suggested that the overall rifting effect had been controlled by NW-trending reverse faults, which are cross-cut or displaced by minor WNW-trending faults. The abandoned Pandurra copper mine was noted as being located on a probable dilational site developed at one such intersection of components of the two fault systems. On continuing tenement EL 5011, issued on 13/09/2012, during year 11 of the project to 12th September 2013, in the annual report submitted by new Tregalana licence operator Strategic Energy Resources Limited, an exploration target lying in a structural setting similar to that of the Pandurra mine was chosen for testing by drilling, having the additional attractive aspect of its proximity to coinciding gravity and magnetic highs. The target, called the Honeymoon Dam prospect, also lies adjacent to a chargeable body identified in data from the 2007 IP survey. The prospect covers ~1.5 km x 3 km adjacent to and 2 km south of the existing Myall Creek deposit mineralised zone, where the nearest two previous drillholes encountered relatively high grade mineralisation (1.9% Cu in hole PUB6; 2.0% Cu in hole PUB22/SAU12). The Honeymoon Dam prospect was subsequently drilled [ during ?2012 ] via 3 ?vertical RC holes for 340.2 m, in which 45 m of HQ and 114.6 m of NQ diamond tail coring were conducted. The holes were collared at sites located in between PUB6 and PUB22. Sadly, due to the later sudden onset of terminal illness to the JV's consulting geologist Dr Wenlong Zang, and his resulting death in August 2014, the majority of data obtained by this drilling programme became lost to the licensees. The scant only drilling data to hand, which were subsequently submitted to DMITRE, consists of laboratory assay results derived from 6 near bottomhole samples of drill cores cut in holes MC002 and MC003 (giving a best result of 0.26% Cu over 1 m). But all of the physical samples, including the original in-field recovered drill cuttings and drill cores, were apparently no longer available to submit, as was reported by the licensees. During licence Year 12, no work was done. During project Year 13, EL 5011 licence Year 3, the new licence partners reviewed all available past drilling and geophysical data, aiming to identify areas where the depth to basement is shallower than 500 m and geophysical features of interest are discernable. The sedimentary copper potential of the basal Neoproterozoic Tapley Hill Formation also was subjected to preliminary scrutiny. Kingston Resources thought that the probably epigenetic Myall Creek mineralisation might have been emplaced by ingress of hydrothermal fluids caused by reverse faulting during a post-Neoproterozoic compressional tectonic event. Porous sandstone and conglomerate at the base of the Tapley Hill Formation acted as a 'trap', and an impermeable carbonaceous siltstone cap formed a 'seal', which in combination caused a local stagnation of fluid flow which led to precipitation of the Cu-Pb-Zn mineralisation. Strategic Energy Resources in conjunction with Kingston Resources (U Energy) continued to assess the large amount of existing drilling and geophysical data sets from within EL 5011 and the surrounds, to develop a further exploration program. The companies retained a belief that the area is highly prospective for IOCG mineralisation in the basement units. During project Years 14 and 15, no on ground work was completed on EL 5011, with work being primarily being desktop based studies including GIS data entry and the interpretation of the newly released solid geology maps produced by the GSSA, and target generation. During project Year 16 on renewed EL 6140, no fieldwork was undertaken. Ongoing access issues to the Cultana Training Area restricted the company to access negotiations and desktop studies.
