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. A diamond drill hole into the Bellatrix EM anomaly intersected hybrid ISCG-IOCG styles of mineralisation and zones of strong graphite. ISCG style mineralisation occurs in pyrrhotite matrix breccia and as late pyrrhotite-chalcopyrite veins synchronous with brittle faults (proof-of-concept that ISCG style of mineralisation occurs in the project area). IOCG style mineralisation occurs as magnetite-pyritte with minor chalcopyirte in a skarn-like assemblage.
The work confirms Minotaur’s hypothesis that ISCG style mineralisation exists within the Mt Woods region. Its is evident as pyrrhotite-chalcopyrite vein sets synchronous with late stage, brittle faults and can be successfully detected through cover using appropriate geophysical techniques. A ground EM survey along sections of the Skylark Shear Zone will be carried out in Q3 of 2017.
