Fluor booked the undisclosed contract value in the June 2019 quarter.

"We worked closely with Cupric Canyon in the project's front-end engineering and design phase to establish a capital-efficient design and execution plan for the project," said Tony Morgan, president of Fluor's mining & metals business. "Fluor was also involved in construction management of the early works for the camp upgrade, bush clearing, transport corridor and surface infrastructure terrace preparation."

Fluor's scope includes upgrading the existing copper concentrator plant and new mine surface infrastructure. The project is expected to produce an average of 62,000t/y of copper and 1.9Moz/y of silver with a life of mine in excess of 20 years.

Morgan added: "We will leverage our local capabilities and extensive copper experience to execute the Khoemacau project with excellence - safely, on time, on budget and with quality."

Fluor has worked in Botswana since the early 2000s and opened an office in Gaborone in 2015.
