The Babel deposit and Nebo deposit are hosted by a sub-horizontal, concentrically zoned, tube-shaped (chonolithic) gabbronorite intrusion. The east-west trending mafic intrusion has a known extent of 5 km, with a gentle 15-degree dip to the south, and in the case of Babel, a less than 10-degree plunge toward the south-west. Babel and Nebo are separated by the steeply-dipping, north-south trending Jameson Fault, with Babel to the west of the fault and Nebo to the east.

Babel consist of three main lithostratigraphic units, which are variably textured leucogabbronorite (VLGN) that forms the outer shell around mineralised gabbronorite (MGN), and barren gabbronorite (BGN) in the core of the intrusion. At Nebo, the main lithostratigraphic units are VLGN that forms an outer shell of the intrusion, around BGN and oxide-apatite gabbronorite (OAGN), which occur in the core of the intrusion at the eastern end (Seat et al. 2007). The Babel Nebo deposits contain two main styles of mineralisation: massive and breccia sulphides, which are a comparatively minor component of the overall sulphide inventory and disseminated gabbronorite-hosted sulphides that represent the bulk of the mineralisation. Massive and breccia sulphides at both deposits comprise, in decreasing abundance, pyrrhotite, pentlandite, chalcopyrite and trace pyrite. In most of the shallower intersections, supergene alteration has modified the primary sulphide assemblages to pyrite and violarite. The disseminated mi ........

The West Musgrave Project consists of the Nebo and Babe pits. The deposits are near-surface and easily accessible by open pit mining with a pre-strip and initial ore stockpile for processing plant commissioning of approximately 32 Mt, some of which will be free dig.

Mining is modelled as conventional drill, blast, load and haul and assumed to be contractor operated during the first five years of operation, transitioning to owner operate in year six. The haulage fleet will comprise up to 25, 220 t haul trucks and optionality is being maintained to allow for these trucks to be fully autonomous in the future.

Mining equipment would include excavators, haul trucks, drill rigs, dozers, water trucks, service trucks and graders. Ore from the pits would be transferred by truck to the run-ofmine (ROM) stockpile pad located adjacent to the ore processing plant. An explosives magazine, conforming to relevant Australian Standards, would store explosives for open pit blasting activities.

Babel will be mined for the first two years to access higher grade, near-surface mineralisation, with Nebo to begin mining in year three.
