Metso Outotec to deliver large energy-efficient grinding mills to West African Resources gold mine

Metso Outotec Corporation’s press release on December 16, 2022, at 11:00 a.m. EET

Australian-based West African Resources has awarded Metso Outotec an order for state-of-the-art comminution equipment to be delivered to their greenfield Kiaka gold project in Burkina Faso. The order value is approximately EUR 30 million and it is booked in Minerals’ fourth-quarter orders received.

Metso Outotec’s delivery includes two Planet Positive PremierTM  grinding mills with a total installed power of 27 MW, as well as Metso Outotec’s proprietary metal and rubber mill linings and spare parts.

“We are pleased to again team up with Metso Outotec for this project. West African is in an exciting growth phase, as we aim to be a multi-project, producing more than 400,000 oz/y of gold in 2025,” says Matt Scully, Project Director, West African.

“The PremierTM semi-autogenous (SAG) mill to be delivered to the Kiaka project is one of the largest gear-driven grinding mills in the world with its 18 MW of installed power. The PremierTM ball mill has been designed to pair smoothly with the SAG mill. Both mills are equipped with fail-safe Metso Outotec Polymer Hydrostatic Shoe Bearing (HSB) systems, significantly increasing reliability and reducing maintenance costs. We are delighted to work with West African Resources on this project,” says Oskar Gustavson, Technology Director, Grinding at Metso Outotec.
