Mine Life2026
The Nova Operation comprises an underground mine consisting of two orebodies, Nova and Bollinger. In addition, the Nova Operation consists of a processing facility with nameplate production capacity of 1.5 million tonnes per annum that produces both nickel and copper concentrates, and associated non-processing infrastructure.

Summary:

The Nova Operation comprises an underground mine consisting of two orebodies, Nova and Bollinger.

Nova-Bollinger lies within the 425km by 50km wide, Mesoproterozoic-age Fraser Zone of the Albany-Fraser Orogen. The Fraser Zone is fault bounded by the Biranup Zone to the northeast, and the Nornalup Zone to the southeast. The Arid Basin forms the basement to the Fraser Zone and the Snowys Dam formation of the Arid Basin is the basement package in the Nova-Bollinger area.

Mafic, ultramafic and granitic intrusions were emplaced in the region during the first phase of the Albany-Fraser Orogeny (~1.30Ga). Later, intense tectonic events (1.12-1.14Ga), metamorphosed the Fraser Zone rocks to granulite facies grade, and the zone is now characterised by gneissic fabrics, complex refolding and major mylonitic zones.

The rocks within the Nova-Bollinger region are consistent with the regional descriptions of the Snowys Dam formation and include pelitic to psammitic gneisses, a local carbonate unit, along with metamorphosed mafic/ultramafic and volcanoclastic rocks. The Nova-Bollinger mafic-ultramafic sill complex that hosts the Nova-Bollinger deposit, is a doubly plunging synform, where a magnetite-bearing footwall gneiss has been identified as the cause of ‘The Eye’ magnetic feature.

The mafic/ultramafic sill complex is a dishshaped package ~ 2.4km by ~1.2km in plan and ~450m in thickness. The rocks of the complex range from peridotite to pyro ........

Mining Methods

  • Sub-level open stoping (SLOS)
  • Longhole open stoping
  • Paste backfill

Summary:

The Nova Operation is based on a designed 1.5Mtpa underground operation with decline access, 1.5Mtpa processing plant and associated infrastructure and services.

Mining of the Nova-Bollinger Deposit is, and will be, by underground mining methods including mechanised mining, open stoping and/or paste backfill stoping.

The mining methods assumed for the Ore Reserve are long-hole sub-level open stoping and sub level open stoping, which is considered appropriate for the for the style of mineralisation under consideration.

A minimum mining width of 3.0m was used for all stoping.

Crushing and Grinding

Processing

  • Flotation

Source: Subscription required

Summary:

the Nova Operation consists of a processing facility with nameplate production capacity of 1.5 million tonnes per annum that produces both nickel and copper concentrates.

The plant included single stage crushing, with conveyors that deliver the ore to a coarse ore bin. Coarse ore is ground in a two stage grinding circuit that comprises a SAG and ball mill. The ore/slurry from the grinding circuit is classified via the mill cyclones and the cyclone overflow undergoes differential flotation. The nickel and copper flotation circuits have dedicated regrind, cleaning and re-cleaning processes to optimise metal recovery in each circuit.

Plant tailings are pumped to a cemented paste back-fill plant with the paste product delivered underground via a borehole and underground distribution system, or plant tailings can be pumped to a tailing storage facility when paste fill is not required in the mine.
