Demetallica Limited, formerly Minotaur Exploration, explored EPM 18624 for copper-gold iron oxide-rich (IOCG) or sulphide-rich (ISCG) systems and for silver-lead-zinc mineralisation. Proterozoic basement within EPM 18624 is masked by Mesozoic cover sediments and is interpreted to be underlain by Soldiers Cap Group rocks including Mount Norna Quartzite, host stratigraphy to the Cannington silver-lead-zinc deposit and the Eloise, Jericho and Osborne copper-gold deposits.
Exploration undertaken by Demetallica (formerly Minotaur) on EPM 18624 sub-blocks retained during Years 1-12 of tenure included ground magnetic surveys by Quantec Geoscience and Terra Search, ground electromagnetic (EM) surveying by GEM Geophysics (2012 and 2018), drilling of one diamond drillhole OR12D01 at Oorindi prospect for 311.2m (QEX Drilling) and office-based studies.
No field work was undertaken in the final year of tenure. Desktop studies during Year 12 included basement interpretation, target review and ranking against targets in the broader Chimera Project area.
As drilling at Oorindi prospect intersected graphitic sediments, interpreted to be the likely source of the modelled EM conductor, and no targets within EPM 18624 were compelling enough to warrant drill testing when compared to other targets in the Chimera project area, EPM 18624 was allowed to expire.
