Metso has been awarded orders by GR Engineering Services (GRES) to provide minerals processing technology for Develop Global’s Yitirrti, formerly Sulphur Springs, copper-zinc-silver project in Western Australia
The value of the order, which is not disclosed, has been booked in the Minerals segment’s 2026 second-quarter orders received.
The Yitirrti project is a high-grade copper-zinc-silver deposit in Western Australia’s Pilbara region. The processing plant has a capacity of 1.5 million tonnes per annum and is progressing toward pre-production.
Kurt Tiedemann, group principal metallurgist at Develop Global, said, “Yitirrti is a key copper-zinc-silver development for us, and getting the process plant right is critical as we move through construction. Metso’s proven technology, process expertise and local support gave us confidence in their equipment package as we bring this exciting project into production in Western Australia.”
Metso’s scope of delivery includes the design, manufacture, testing, and delivery of process technology for the concentrator supporting copper and zinc processing. The equipment package contains Metso’s Nordberg C Series jaw crusher and Nordberg HP450e cone crushers, an apron feeder, and TankCell flotation cells, thickeners, Stirred Media Detritor (SMD) regrind mills and slurry analysers.
David Tulloch, vice president, Minerals, Asia Pacific at Metso, said, “We are excited to be selected as a key technology partner for the Yitirrti project. The scope reflects the strength of our integrated offering across this type of flowsheet. Our proximity to the site through our Karratha Service Centre will provide a strong platform for ongoing aftermarket support as the project moves into operation.”
Metso’s solutions have been developed to support efficient, reliable, and sustainable minerals processing. The company’s portfolio of comminution, flotation, and dewatering technology helps customers to achieve high recovery rates, greater resource efficiency, and optimised lifecycle performance in base metals processing.
