Metso wins major order for Tanzanian gold project

Sotta Mining Corporation Ltd., an 80%-owned subsidiary of Perseus Mining Limited, has awarded Metso a significant equipment supply contract for the Nyanzaga gold project in northwest Tanzania

The order comprises a Superior MKIII 4265 primary gyratory crusher and two Plus Premier grinding mills, which together will provide 21MW of installed power. Valued at more than EUR 20 million (approx.US$21.5mn), the order was booked in the Minerals segment’s first-quarter intake for 2025.

Matt Cavedon, general manager, project development at Perseus, said, “Perseus is looking forward to the successful deployment of Metso’s state-of-the-art comminution technology, alleviating gearboxes with the benefits of precision control and high efficiency.”

Oskar Gustavson, technology director, Grinding at Metso, added, “The Premier SAG mill and ball mill to be delivered to the Nyanzaga project feature low-speed synchronous motor drives without conventional gearboxes. This makes the mills very reliable and very efficient – a 2% saving in energy consumption when compared to traditional gearbox-driven mills. Both mills are equipped with Metso’s fail-safe Polymer Hydrostatic Shoe Bearing systems, significantly increasing reliability and reducing maintenance costs.”

Metso’s Premier horizontal grinding mills are tailored to specific customer needs, combining cutting-edge technology, process know-how, and design flexibility. Alongside these, the company offers pre-engineered Select mills, advanced mill reline systems, and a broad portfolio of liner solutions, including the innovative Megaliner. Metso also supports customers with inspection programs, Life Cycle Services (LCS) for scheduled maintenance and shutdowns, and a complete range of spare and wear parts. The Superior MKIII gyratory crushers are built to deliver high throughput and minimal downtime, enhancing operational efficiency.
