Name of the Project
Central Eyre iron project (CEIP).

Location
South Australia.

Client
Iron Road.

Project Description
The CEIP includes a proposed long-life mine and processing plant, as well as regionally supportive rail and port infrastructure.

The mine has been designed for in-pit crushing and conveying, with fully mobile and semimobile crushers, as the characteristics and size of the orebody are ideally suited to this mining method.

Mobile in-pit crushers will be connected to the main pit conveying system through smaller dedicated fully mobile conveyors. Each component is relocatable using transport crawlers, allowing for components to be easily moved during pit advance.

The optimisation programme proposes the construction of a modularised ore-processing facility on the south-east perimeter of the proposed pit.

The facility has three discreet processing trains to provide a high level of plant availability and minimise operational downtime.

The processing trains will incorporate seven main modules – a semiautogenous grinding mill, a rougher magnetic separator, a gravity beneficiation circuit, a regrind mill, a ball mill, a cleaner magnetic separator and a tailings filter building.

The facility will process up to 175-million tonnes (dry) a year of feed material at an overall average head grade of about 16% iron, producing 21.5-million tonnes a year of iron concentrate (dry basis) at an estimated 67% iron.

Dewatered coarse tailings from each process train will be discharged onto the tailings transfer conveyor. The filtered moist fine tailings will be transferred to the waste rock conveyor originating from the mine. The combined tailings and waste rock will be stacked on the integrated waste landform by a mobile spreader. This method minimises water use and reduces the waste storage footprint.

Iron concentrate will be transported from the mine site by a standard-gauge, heavy-haul rail system along the infrastructure corridor to a new port facility at Cape Hardy, when the bulk commodities port facilities are located 7 km south-west of Port Neill. The port is planned to have an initial capacity of 70-million tonnes, with the main export wharf capable of handling Panamax and Capesize vessels. Two shipping berths for bulk iron-ore carriers will be serviced by a slewing, luffing and travelling shiploader.

Jobs to be Created
The CEIP will employ about 1 950 people during construction and 700 during operations on the Eyre Peninsula, in addition to the workforce required in the Adelaide head office. 

Net Present Value/Internal Rate of Return
A geared, post-tax net present value, at a 10% discount rate, of $1.4-billion and and internal rate of return of 15% is the minimum targeted outcome for the  project commercialisation phase.

Value
$3.7-billion.

Duration
Not stated.

Latest Developments
Capital costs for the CEIP have been reduced by about $295-million, from $4-billion to $3.7-billion.

Iron Road’s partner China Railway Group Limited (CREC) has delivered the capital savings as part of the joint project commercialisation programme, with further savings expected from a final mine plan and schedule review.

CREC’s cost reductions have been primarily driven by the Chinese company’s in-house procurement systems and leverage associated with key capital items and equipment required, Iron Road has said.

Key Contracts and Suppliers
None stated.
