An irregular area covering pastoral land ~15 km to the immediate west and north-west of Port Augusta has been explored for possible economic buried IOCG and other significant metallic mineralisation, which could have formed in the vicinity of the inferred subsurface continuation of the northern Roopena Shear Zone, a possible splay off the Kalinjala Mylonite Zone, where it is concealed by younger Proterozoic rocks of the south-eastern Gawler Ranges district, such as the Gawler Range Volcanics, Pandurra Formation, Umberatana Group sediments and Beda Volcanics. After the Kimban Orogeny ceased, a probable lengthy continuation of activity of this major crustal penetrative tectonic feature, which represents the domain boundary between the Olympic Domain and the Spencer Domain in this part of the eastern Gawler Craton, was seen as being critical for focussing fluid flows into dilational structures spatially associated with this part of the shear zone. However, all of the exploratory drilling which had been done in the area previously had not gone beneath the Gawler Range Volcanics (GRV) stratigraphic section, so the nature of the geology which is present beneath this unit remained unknown. Within parts of the Olympic Domain, notably at Prominent Hill, the base of the GRV acts as a trap concentrating dense IOCG-related mineralising fluids which were introduced along splays to the domain bounding Karari Shear Zone during the Hiltaba magmatic event, and therefore it was expected that a similar situation could apply at Mount Arden. There, gravity highs with inferred sources lying at ~250 m depth, close to the predicted base of the GRV, were targeted as representing possible dense haematite-rich mineralised bodies. The targeted emplacement zone of interpreted structural disruption runs north-south along the common boundary shared by Kingston's Six Mile Hill and Mount Arden tenements. Within and adjacent to it, there appeared to be much geological variation in the depth to the top of the GRV. Existing drillholes in the Spencer Domain to the west of EL 5498 had encountered the GRV near the surface, whereas others in the Olympic Domain portion on EL 5498 had found it lying at ~300 m depth. The few past holes located within the structural contact zone did not intersect the top of the GRV, but only penetrated cover to ~100 m depth. At the outset of the first licence year, in October 2014, following Kingston's recent corporate takeover of Westernx, Daishsat were contracted to read a total of 1400 new gravity stations across parts of the adjoining licences, on initial 500 m x 500 m regular grids that were later infilled in part to 250 m centres. 673 of the new gravity stations were located on EL 5498. 3D inversion modelling of the new detailed gravity data performed by Kingston further defined a number of regional gravity high features in the central-southern part of the licence. In recognition of its attractive exploration model, and as an approved part of the SA Government's PACE Frontiers collaborative drilling with industry initiative, Kingston was successful in being granted $2 million of exploratory drilling subsidy funds by DSD for carrying out up to 2400 m of fully cored stratigraphic diamond drilling in a 5-hole programme that would be undertaken within the two licences comprising its Six Mile Hill Project. The high level of outside-derived drill funding was because of Kingston's participation in this Stage 1 of the Mineral Systems Drilling Program (MSDP) that involved the Deep Exploration Technologies Cooperative Research Centre (DET CRC) as well as the Geological Survey of South Australia, CSIRO, Olympus-Zeiss and Boart Longyear, plus other research participants and service company affiliates. This program had been set up with an initial aim of unravelling mineral systems associated with newly discovered mineralisation developed along the southern outcrop margin of the GRV sequence, and also involved Minotaur Exploration in other planned drilling work on that company's Peltabinna and Mount Double project areas. Besides obtaining new stratigraphic and other regional geological information, an important aspect of the MSDP was to map any alteration sequences that occur within the GRV and underlying rocks, and incorporate this knowledge into regional geochemical databases that will enable better recognition of subtle and distal alteration haloes related to known IOCG deposits. The MSDP also provided an early opportunity to field test DET CRC's revolutionary new technologies such as the Wireless Sub, Fluid Management System, AutoSonde, AutoShuttle and especially, Lab-at-Rig, in a conventional 24/7 soft and hard rock diamond drilling situation. Early in 2015, a set of pre-drilling orientation data was collected by both Kingston and its MSDP partners from previous holes drilled within EL 5498 and the surrounding region, for which the partners geologically relogged and hyperspectrally logged the holes. One hole, TR3, that was drilled by Dampier Mining in 1981 and is located within the Olympic Domain within EL 5498 on the edge of the shear structure projection, yielded some interesting information. It had reached the top of the GRV at ~350 m depth, having intersected ~60 m of Pandurra Formation overlying the GRV, and ~40 m of Beda Volcanics with Backy Point Formation overlying the Pandurra. Weakly elevated copper was identified, persisting from the Beda Volcanics beds through to the bottom of the hole at 400.4 m depth, with a peak content of 1150 ppm Cu evident within the Backy Point Formation. The interval of GRV that was penetrated had weak copper anomalism, up to 500 ppm Cu. Kingston thought that the overall sediment package which had been encountered within TR3 would be present within its Olympic Domain planned holes, and it interpreted the weakly anomalous copper in the overburden to be an indication of copper mineralisation at depth, awaiting discovery. The MSDP drilling campaign commenced on 1/8/2015, with the first hole located on EL 5626 Six Mile Hill. Another three holes were completed before the Kingston - supported part of the campaign ended on 22/10/2015. Only one fully cored vertical hole, MSDP02, was drilled on the subject EL 5498 Mount Arden, into the 15DDSM003 gravity target, attaining a total depth of 564.5 m and being terminated within interpreted Beda Volcanics basalt. This basalt underlies the base of Tapley Hill Formation sediments at 398 m. Drill core assay results are pending, but minor copper mineralisation (disseminated chalcopyrite) was observed at the basal contact of the Tapley Hill Formation (final 1-2 m). The MSDP02 hole location had been chosen in the hope of encounteringing fertile pre-GRV rocks at relatively shallow depths due to an uplifted basement fault block, However, the hole instead found a volumetrically significant thickness of relatively dense (2.8-2.9 SG) younger Beda basalt, which probably is the source of the modelled gravity anomaly which was targeted. The option of continuing the drilling from this point downward into the Pandurra Formation and then the GRV was deemed to be a step beyond the scope of the campaign. The correctness of this decision was later borne out when trial downhole seismic and surface seismic surveys were conducted at the MSDP02 site, with the interpreted results suggesting that the depth to pre-GRV basement there might be as deep as 2.2 km. In view of this outcome, Kingston downgraded the perceived prospectivity of the Mount Arden tenement with regard to economically accessible IOCG mineralisation, and allowed its tenure to lapse at the end of licence Year 2 without doing any further exploration.
