Caltex has begun supplying on site diesel as part of its $200 million contract wit the Roy Hill iron ore mine.
The two year contract will see "Caltex supplying about 120 million litres of diesel to Roy Hill over the course of the contract to meet all the mine's fuel needs during this important start-up phase and as production is expanded," Caltex's national manager business to business sales, Phil Amos, said.
"We recently commissioned on site fuel storage infrastructure at Roy Hill as part of our commitment to manage all of the mine's diesel requirements," he said.
"Deploying a fleet of four dedicated road trains, we will transport diesel about 400 kilometres by road from Caltex's 40 million litre storage terminal at Port Hedland to facilities at the Roy Hill mine."
The terminal is one of 12 operated by Caltex nationally.
The fuel will be used for trucks and power generation on site.
Caltex will also supply the diesel powered locomotives that will haul the iron ore from Roy Hill to Port Hedland.
