Granny Smith, Western Australia

The contract: Haulage

Bis provided the management and delivery of off-road load and haul, and other ancillary works, at Gold Fields’ Granny Smith mine site.

After securing the initial contract in 2007, the scope of works increased over time to include:

• labour and equipment for haulage of gold ore from the pit to run-of-mine
• site road maintenance
• civil construction and earthworks » tailings reclaim
• front end loaders for crusher feed
• mobile maintenance and fully equipped onsite workshop

The out-of-pit haulage of ore from the Wallaby Pit to the Granny Smith run of mine, covered a 15km distance and saw approximately 1.6 million tonnes of ore relocated each year using dual-powered road trains and associated front end loaders.

The critical site road maintenance for the haul road, site access road and the unsealed Goldfields airstrip included grading, rolling and water cart operations.

Bis also supplied and maintained a screening plant which was used in the reclamation of tailings being utilised for paste fill in the underground operations.

Key project achievements

Bis secured the scope of work to build approximately six kilometres of causeways across Lake Carey for Gold Field’s exploration purposes.

Bis completed multiple forward earthworks and civil projects for Gold Fields, including pre-plant construction earthworks, land clearing projects, and the construction of the tailings pad and water catchment dam.

Granny Smith was one of the first trial locations for Rexx, Bis’ proprietary 160-tonne dump truck. The trial helped to confirm Rexx’s design expectations including the capability to haul fully loaded on steep inclines.
