Continued exploration by Minotaur and its current joint venture partner Sumitomo Metal Mining Oceania, searching for possible economic buried silver-lead-zinc, copper-gold or gold only mineralisation which might have formed as primary epithermal/hydrothermal deposits hosted by Palaeoproterozoic basement, is primarily targeting interpreted prospective strata seen on regional aeromagnetic images. EL 4844 Mingary covers part of the south-eastern corner of the Palaeoproterozoic Olary Domain of the Curnamona Province and the western portion of the Broken Hill Domain, with the two domains separated by a domain boundary which is expressed in the landscape as the Mundi Mundi Fault scarp. Rare, scattered outcrop and subcrop consists of quartz veining with gossanous iron oxide, albitised rock, psammites, pelites and psammopelites. These outcrops are the medium to high grade regionally metamorphosed and strongly deformed sedimentary, volcanic and intrusive rocks of the Palaeoproterozoic Willyama Supergroup (Conor and Preiss, 2008). In the Olary Domain, west of the Mundi Mundi Fault, the Willyama Supergroup has been intruded by extensive volumes of Mesoproterozoic granitoids and scattered mafic dykes which are genetically and temporally related to the c.1580 Ma Olympic Dam mineralising granites of the Gawler Craton. 26 square km or ~7% of the former area of the subject EL 4844 Mingary, comprising all of its former Sub-block C, has recently been relinquished in accordance with the conditions of the Border Joint Venture Project tenements' Amalgamated Expenditure Agreement (AEA) that was made with DSD in April 2015. These conditions required a 10% overall reduction of the total area of the JV tenements to be effected during mid-2016. Exploration activities undertaken on the now relinquished ground portion have comprised: - during the period June to October 2006, ground EM, ground gravity and ground magnetic survey coverages were acquired at the Trinity prospect on EL 3596 Mingary to follow up an aeromagnetic anomaly of interest. 108 of a total 670 gravity stations were read by way of infill to a September 2002 BHEI gravity survey, to help define a minor gravity anomaly recognised near the historic Trinity copper mine. 695 moving loop EM stations were read, which revealed a coherent EM conductor at shallow depth (Anomaly 1). 2206 ground magnetic stations were also read across the mine prospect to better define the curvilinear aeromagnetic anomalism. - at the end of January 2007, one angled RC exploratory hole, 07RCMIN011, was drilled at the Trinity prospect on a 60 degrees southwards declination, to a hole total depth of 180 m. This hole encountered a sequence of quartz-feldspar-muscovite±magnetite schist to mafic gneiss carrying trace pyrite-pyrrhotite-chalcopyrite. A sulphide-bearing interval intersected at 136 m downhole returned 4 m @ 0.128% Cu and 1.1 g/t Ag. No other significant drill sample assay results were returned. - during January 2009, a very small part of a helicopter-borne VTEM survey was flown there along east-west flight lines 250 m apart, using a 30 m EM sensor mean elevation above the ground surface. The resulting AEM data delineated one late-time conductive anomaly, designated as EmV006. This anomaly was subsequently followed up in 2012, now on renewed EL 4844 Mingary, by acquiring three lines of ground-based moving loop EM coverage. No significant bedrock conductors were detected in the MLEM data. The relevant raw data subsets generated by all of these activities are included herein.
