An area centred ~80 km east-northeast of Hawker, in the vicinity of the Martins Well Diapir, has been explored for possible economic buried epigenetic occurrences within Adelaidean metasediments of gold, silver, cobalt, copper and manganese mineralisation, since all of these metals had lately been attaining record or very high market prices. Initially, the licensees' prime intent was to define the extent at Mount Josephine of the high grade cobalt mineralisation that had been identified by previous explorers. However, an abrupt crash in the cobalt price in July 2019 caused attention to be diverted towards seeking manganese oxides with cobalt credits. The exploration model used involved the weathering, leaching, scavenging and concentration of the high value elements cobalt and nickel into manganese deposits which had developed primarily above the Etina Limestone and Skillogalee Dolomite. This situation can occur because manganese sols are unusual among oxide sols in that their particles carry a negative charge, and therefore preferentially adsorb cations out of solution, especially divalent elements like cobalt, nickel, copper and silver. During the first licence year, solely office-based activities consisted of compiling and analysing historic data. Extensive research into records of previous exploration was undertaken, and the surface geochemical sampling data were imported into a Mapinfo GIS dataset. Ternary radiometric images of airborne survey data were examined to find thorium anomalies which could denote the upper, iron rich ferricrete capping to preserved manganese-rich laterite profiles which have formed on limestone and dolomite bedrock buried under shallow alluvial/colluvial cover. During licence Year 2, no work was done, due to the travel and social lockdown complications arising from the COVID-19 disease outbreak in Australia. As the outlook for resumption of normal business did not improve by the end of the year, it was decided to allow tenure to lapse at expiry then.
