Maslins IOCG Projects
Nankivel porphyry copper-gold target – a robust untested porphyry target
Investigator continues to utilise collaborative research to identify mineral deposits. Results from the 2015/16 government-funded national AusLamp magneto-telluric (“MT”) survey program in South Australia, showed a regional-scale MT geophysical corridor extending from under Olympic Dam, Carrapateena, and continuing through the centre of the Eyre Peninsula towards the Investigator’s Paris/Nankivel projects. The research suggested the existence of a major pathway for mineralisation to have reached the deposit-forming level from deeper within the earth during the Olympic Dam IOCG mega-event 1.5 billion years ago.
Following the release of survey results, Investigator acquired four 100%-held tenements 90km northwest of Port Augusta and about 50km south of OZ Mineral’s Carrapateena copper deposit. In early 2016, the Company identified a new large iron-oxide copper gold (IOCG or “Olympic Dam style”) gravity anomaly modelled as suitable IOCG-style target, “Maslins”, within tenement EL5705 “Whittata”.
Reviews and re-interpretation of regional drilling showed Maslins to be in optimum depth and position for IOCG formation. Investigator views Maslins be a major candidate for the next generation of IOCG targets within the Olympic Dam belt. Interest in the large target continues to build as a potential contender to fill the gap in deposit sizes between the super-giant Olympic Dam and smaller Carrapateena and Prominent Hill deposits.
