Osino Resources, an exploration and development company in Namibia, has awarded Metso an order for the delivery of key process equipment for its Twin Hills gold project.

Located 150km northwest of Windhoek within the Damara Orogenic Belt, the project is currently in the development stage.

The total value of the order exceeds €20m ($23.5m) and is booked in the second quarter orders of Metso’s minerals segment.

Metso will supply an integrated equipment package comprising advanced crushing and concentration technology for the Twin Hills greenfield gold plant.

The high-throughput crushing circuit is designed for efficient ore processing and features a Superior MKIII primary gyratory crusher, apron feeders and Nordberg HP900 cone crushers.

Metso will also supply two HRT high-rate thickeners equipped with Reactorwell feed technology and five Larox FFP3512 filters for concentrate thickening and tailings dewatering.

These thickeners and filters are part of the Metso Plus portfolio, which is known for its high performance and dewatering capacity.

Metso minerals sales Africa vice-president Charles Ntsele stated: “As a leading supplier of process technology globally, Metso is pleased to be selected as a trusted partner for Osino Resources’ flagship Twin Hills gold project in Namibia.

“Our energy-efficient and water-conscious technology will support Osino Resources in reaching their targets. This project also highlights Metso’s commitment to continued support and development of the Namibian mining industry.”

In June 2023, Osino announced a definitive feasibility study for the Twin Hills project, which is based on 2.94 million ounces (moz) reserves.

The study outlines a 13-year open-pit mine with an average annual production of 160,000oz at an all-in sustaining cost of $1,000/oz.

The Twin Hills project benefits from a straightforward executable design, significant growth potential and proximity to essential infrastructure.

In June 2025, Metso signed a three-year agreement with BHP to supply metallic liners for the company’s Western Australia iron ore operations.
