Western Australia-based Celsius Resources has recovered notable levels of cobalt during testing at its Opuwo project in Namibia.

The company announced that it had achieved grades of up to 1.1 per cent cobalt within two minutes of conventional flotation at 64.2 per cent recovery. Up to 88 per cent of the recovered cobalt and 87.3 per cent of recovered copper came from sulphide concentrate.

Celsius hopes to carry out leaching tests within the next week to improve recovery grades and determine the further viability of sulphide concentrate-led cobalt production.

Brendan Borg, managing director of Celsius, explained that the discovery potentially added significant value to the Opuwo project, located in the northwest of the south African country about 800 kilometres from the capital city, Windhoek.

“The metallurgical test work program for the project has demonstrated that conventional sulphide flotation techniques can be employed to produce mineral concentrates at Opuwo, with optimisation ongoing to further improve grade and recovery,” he explained.

The Opuwo cobalt project covers approximately 1470 square kilometres of land and has seen several previous explorations; Celsius plans to commence drilling with project partners Opuwo Cobalt and Gecko Namibia in March 2018.
