A small licence area centred ~70 km east of Marla has been taken up to explore for possible economic buried sedex style base metal deposits or IOCG style mineralisation which may exist there, hosted by largely unknown Proterozoic basement rocks, including probable granitic plutons, which it is thought have evolved in a complex cratonic margin setting which was subject to a long history of crustal attenuation and fault movements / hydrothermal system activity. The rationale behind initial exploration conducted on EL 5459 by the JV partners has been to investigate a conductive structure revealed in its north-western portion by a previously attempted, prematurely discontinued moving loop ground EM survey carried out by EL 3566/4761 licensee Raisama in 2011. Follow-up moving loop and fixed loop ground EM surveys carried out over this geophysical feature by Sandrib in December 2014 successfully identified a large, strongly conductive structure subcropping between 100 and 200 m below ground level, and persisting to at least 500 m below ground level, with a strike length of >1800 m and dipping at about 45° towards WSW. It was decided to test this anomaly with a small drilling program, in the hope that the conductive response in the ground was the result of the presence of sedex style sulphide mineralisation. The actual depth of drill penetration required to reach the inferred Proterozoic basement in the subject licence area was, until the completion of the subject 2015 PACE-assisted drilling program, unknown. The expectation of solving this knowledge gap was an important factor in the licensees' success in having their PACE Initiative Year 8 collaborative drilling subsidy proposal accepted by DSD, as approved drilling project DPY8-11. During July 2015 the Macallum Group, under an earn-in option with Sandrib, drilled a total of 4 vertical or steeply inclined rotary mud precollared, HQ/NQ2 diamond cored holes for 926 m into the Lambina EM anomaly, at three sites spaced approximately 600 m apart along a NNW-SSE aligned traverse. Beneath a Cenozoic and Mesozoic sedimentary cover sequence, Proterozoic basement rocks consisting of black graphitic shales intercalated with other fine grained siliciclastic marine sediments were encountered in each of the four holes at depths ranging between 96 and 116 m, much shallower than prognosed, and the holes remained in these sediments until total depth. The structural orientation of the shales was inferred from bedding angles measured in abandoned drillhole LMD001 (TD 198.3 m) and the adjacent daughter hole (LMD001A, TD 305.1 m) that was wedged off it through casing at a higher level after the former began to track along bedding. The strike of the beds appears to be approximately towards the NNW, and their dip is about 50°. These bedding angles, measured with an electronic survey instrument within the drillholes, closely match the dip of the modelled EM conductor. Field measurements done on the cored graphitic shales using conductivity meters showed a strong conductive response, and it was therefore concluded that the targeted large conductive EM anomaly is caused by the lithological properties of these beds. Strong deformation, and associated weak to moderate chlorite-biotite-carbonate-pyrite alteration, were observed in the cored Proterozoic sediments in LMD001A, the first hole to reach basement. Sulphides are present throughout all the basement lithologies, particularly in the black graphitic shales. Pyrite is the dominant sulphide, with only very rare chalcopyrite and sphalerite. Following first pass geochemical scanning of the drill cores in the field using a Niton portable XRF spectrometer, when 517 semi-quantitative analytical readings were taken, 98 selected one metre interval split drill core samples from the three holes which had reached basement were sent for assaying for gold as well as a suite of base metals and other elements. A maximum value of 1 m @ 0.65% Zn was returned from hole LMD001A over the depth interval 241-242 m. This core sample contains black, graphitic fault gouge and a small layer of strongly altered (chlorite-biotite-pyrite-carbonate) shale. Otherwise, no assay results of economic significance were returned. 12 core samples of black graphitic shale taken from holes LMD002 and 003 were analysed for their carbon content. Values ranged from 3 to 7.5% C, denoting an abnormally high content. Despite the lack of encouragement provided by this PACE drilling project's outcome, the licence JV partners remain optimistic that the wider area of EL 5459 is still prospective for sedex or IOCG style base metal mineralisation.
