Mt Isa/McArthur Basin mineralised sequence is one of the world’s major copper, lead, zinc and silver provinces hosting several deposits including the Mt Isa, George‐Fisher, Hilton, Gunpowder, Century, Valhalla (U), Westmoreland (U), Constance Range (Fe) deposits. The Western Succession copper‐zinc‐lead‐silver deposits make the region one of Australia’s most sought‐after target regions. The currently operating mines to the north and south of the project areas along the same structures confirms this part of the region’s potential to host large deposits. Within the Mt Isa Block, four Proterozoic tectono‐stratigraphic terrains are recognized which comprise an older basement core overlain by three younger Proterozoic sedimentary sequences referred to as Cover Sequences 1, 2 and 3. These cover sequences are related to major episodes of intra‐cratonic rift and sag phase sedimentation. The Middle Proterozoic rocks record a complex history of intra‐continental rifting and subsidence during the period 1,800 to 1,590 million years (Ma), followed by compression, basin inversion and regional wrenching during the Isan Orogeny (1,590 to 1,500 Ma). Within the Western Succession, Cover Sequence 3 east of the Mount Gordon Fault is assigned to the Mt Isa Group (maximum thickness of 4,500 m) within the Leichhardt River Fault Trough. The equivalent sequence to the west of the fault is assigned to the McNamara Group (maximum thickness of 8,500 m) deposited in the Lawn Hill Platform. In the far north of the Mt Isa Block, this rock sequence is termed the Fickling Group. Cover Sequence 3 hosts many of the significant base metal deposits within the Mount Isa Block, including the Mt Isa, Mount Gordon, Mount Oxide, Hilton and George Fisher base metal deposits within the Mt Isa Group, and the Lady Loretta, Century and Lady Annie deposits within the similar‐aged McNamara Group.
