Three areas centred ~120 km west south-west of Coober Pedy and lying in the northern part of the Gawler Craton, one located within the Mabel Creek Domain and the other two being adjacent and further to the south, within the Christie Domain next to a section of the roughly east-west trending Karari Fault Zone, are being explored for possible economic buried epithermal/hydrothermal IOCG mineralisation. At the start of field work, during October 2012, licensee Teck acquired a 415 line km airborne magnetic/radiometric/digital terrain model survey over the Cyclops magnetic anomaly, along north-south flight lines spaced 100 m apart, using a 40 m mean sensor height above the ground surface. This subsequently much better defined magnetic anomaly, now seen as a 2600 nT intensity, complex and internally fault offset 2 km long oval-shaped anomaly, lies on the boundary between EL 4891 and EL 4892. Locally on its southern side, the clear magnetic signatures of three impinging Neoproterozoic Gairdner Dolerite dykes appear to terminate at, or within, the anomaly. On its northern side, a narrow Permian sediment-filled basin has been interpreted to abut the Karari Shear Zone hanging wall composed of high grade gneiss metasediments. During February 2013, to augment 600 m spaced regional gravity data, Teck acquired a semi-detailed ground gravity survey over Cyclops on a regular 250 m x 250 m grid, with 198 stations read on EL 4891 and 92 on EL 4892, including some local infill coverage and two detailed north-south traverses. The new gravity data disclosed a discrete, 1.5 mGal magnitude residual gravity anomaly, ~ 1.2 km x 700 m, which is partly coincident with the magnetic anomaly. Unconstrained, first-pass 3D inversion modelling of the geophysical data was undertaken, and it showed Teck that the combined magnetic-gravity anomaly has geophysical source characteristics permissive of a magnetite alteration system. While the ground gravity survey was in progress, 82 soil samples were collected along the more detailed north-south gravity lines. Samples were sieved to minus 250 microns and analysed for a multi-element suite by aqua regia/ICP-MS and a proprietary enzyme leach method (the latter was not considered effective due to a wide range of pH values in the soils that have developed atop transported cover materials). Results of the aqua regia-ICP-MS method highlighted three consecutive samples forming a weak gold (1.5-4.5 ppb Au) and silver (22-26 ppb Ag) geochemical anomaly directly over the Cyclops magnetic anomaly. However, elsewhere near the prospect there are lesser, more difficult to explain weak and diffuse gold geochemical responses. During the second year of the licences' tenure, a total of 25 pulps from the 2013 soil sampling programme were re-analysed using a low-level detection leach method provided by Intertek Genalysis’ Perth laboratory. The samples had been collected along two lines that crossed over the Cyclops magnetic anomaly, and their previous analysis results had indicated weak gold and silver anomalism. But the results of the re-analysis exercise were disappointing, and there were no obvious trends in the values obtained that corresponded to the location of the magnetic anomaly. Nevertheless, the lack of a firm surface geochemical footprint at Cyclops was regarded by Teck as not serving to downgrade its prospectivity. Also during this reporting period, considerable time and effort was invested by the licensee in preparing a detailed Declaration of Environmental Factors (DEF) to support an application that it made to DSD for approval to drill test the Cyclops target. The proposed diamond drilling campaign was subsequently approved under E-PEPR 2013-136. During the third year of tenure, no field work was done. In August 2014, Teck optioned both licences to MinQuest Ltd, who had identified the Cyclops target as having a similar geophysical signature to the world class Prominent Hill IOCG deposit, being a magnetic anomaly offset from a large gravity anomaly sitting on a deep, sub-crustal lithosphere - tapping, long-lived major structure (the Karari Shear Zone) that formed on a continental palaeomargin. Only the relative geometry of the magnetic and gravity anomalies is reversed as compared to Prominent Hill. Minquest commenced managing the exploration programme, as part of the process for earning an interest in the project. Early in 2015, MinQuest applied to the SA Government through DSD to be granted PACE Initiative Year 8 collaborative drilling project funding to complete four diamond drillholes in order to test their exploration model, and to determine the sources of both the gravity and the magnetic anomalies. The application was successful and the proposed work was given the PACE Discovery Drilling project designation DPY8-34 [for obtaining the separately held open file final report on this project, see Env 12977]. During the fourth year of tenure, in May-June 2015, MinQuest completed drilling 3 rotary mud precollared inclined diamond cored holes at Cyclops, for a total penetration of 1181.7 m. The last two holes, the deepest of which was CY15-002 at 600.6 m, adequately tested the causative sources of both the gravity and magnetic anomalies, by penetrating basement rocks hidden under between 130 m and 150 m true vertical depth of cover that are comprised mainly of haematite and sericite - altered BIF plus lesser greywacke, gneissic and calcsilicate metasediments, which have been intruded by a heavily haematite and potassic - altered felsic schist. Minor amounts of copper, lead and zinc were identified therein, in part corresponding to visible trace to minor amounts of chalcopyrite, galena and sphalerite. The BIF has an average density of 3.16 g/cm3, with a peak value of 3.46 g/cm3. It is also highly magnetic, with drill core measured susceptibilities being up to 1000 x higher than those of the cover sediments and the underlying felsic schist. Numerous tectonic structures were intersected in the drilling, some of which appeared to have been reactivated several times during the geologic evolution of the region, which should indicate that there is significant potential for a structurally controlled mineralised body to be present. But disappointingly, no evidence of epithermal brecciation was encountered. After logging and assaying the drill cores, Minquest concluded that its two PACE drillholes at the Cyclops prospect had revealed that several of the key mineral systems mapping criteria for IOCG deposits, as were outlined by Groves et al. (2010), are present in the project area. It said that effective further exploration would rely on determining the extent and age of the felsic schist and its potential link to mineralisation, as well as looking for dilational areas along the identified basement structures which could represent former structural traps which acted to halt the passage of mineralising fluids. In its opinion there are several other, more discrete gravity anomalies to the south-east of the drilled area that may represent additional targets. No other field work was done on the subject licences over the following three years, until a decision was made to allow their tenure to lapse. The JV earn-in agreement with Minquest was terminated early in 2017. After Pursuit Minerals purchased the licences from Teck later on in 2017, it conducted an exploration data review and carefully checked the report documentation for all previous companies' learnings about the known and probable settings for mineralisation that is related to the Karari Shear Zone. By April 2019 it had reached the conclusion that all plausible geophysical targets in the Tallaringa area were already sufficiently tested, and also thought that no other IOCG-prone geophysical targets except for Cyclops were apparent there.
