Osino Resources has awarded Metso with an order for the delivery of key process equipment for its Twin Hills gold project in central Namibia, some 150 km northwest of Windhoek.

The total value of the order is over €20 million ($24 million).

Metso’s integrated equipment package for the Twin Hills greenfield gold plant consists of crushing and concentration technology.

The crushing circuit for efficient processing of ore is built around a Superior™ MKIII primary gyratory crusher, apron feeders, and Nordberg® HP900™ cone crushers. For concentrate thickening and tailings dewatering, Metso will deliver two HRT High Rate Thickeners equipped with Reactorwell™ feed technology, and five Larox® FFP3512 filters. The thickeners and filters are part of the Metso Plus portfolio, offering high performance and high dewatering capacity, the company says.

Charles Ntsele, Vice President, Minerals Sales, Africa, at Metso, said: “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 released a definitive feasibility study for Twin Hills based on 2.94 Moz reserves, outlining 13-year open-pit mine with average annual production of around 160,000 oz at an all-in sustaining cost of about $1,000/oz.
