The 34-month contract is for a further cutback at the Rocky's Reward pit and work at a satellite pit.

The scope included mine planning and engineering, drill and blast, mining of overburden and ore, and rehandling services to the Leinster processing facility.

CIMIC CEO Michael Wright said the award continued Thiess' strong working relationship with Nickel West.

"We're pleased to continue our support at Rocky's Reward, delivering value through our mining expertise and our experience in planning and scheduling mining around existing underground workings," he said.

Thiess managing director Douglas Thompson said the contract recognised the company's ability to bring the right equipment, people and expertise to projects.

"We look forward to building on our experience at Rocky's Reward where we delivered strongly in production and safety," he said.

"We also look forward to continuing to provide opportunities for local jobs and suppliers."

Thiess recently won $845 million of coal contracts in just one week of March with clients including BHP and Glencore.

CIMIC shares were 2c lower at $42.08 this morning, valuing the company at A$13.6 billion.
