Minotaur and OZ Minerals are collaborating in exploration around the Prominent Hill mine, through an exploration alliance.

Minotaur’s target generation model uses ground EM to source iron sulphide copper-gold (ISCG) conductors; potential hosts for copper mineralisation. ISCG style mineralisation occurs in pyrrhotite matrix breccia and as late pyrrhotite-chalcopyrite veins synchronous with brittle faults. IOCG style mineralisation occurs as magnetite-pyritte with minor chalcopyirte in a skarn-like assemblage.

Late in 2017 a single diamond hole into the Maverick EM anomaly revealed chalcopyrite mineralisation of about 1% over a 35m interval, requiring further investigation.
