The first one of eight PQ diamond drill holes has been completed. The ore was intercepted at the exact location modelled reinforcing the consistent nature of the dolomite ore formation.
While there have been heavy rains on site delaying mobilisation, drilling is now occurring on two shifts and the remaining seven holes are scheduled to be completed by end of April. Approximately 4t of fresh metallurgical samples will be obtained during the programme.
Past metallurgical test work carried out on Opuwo focused on producing a concentrate via flotation and then recovering the cobalt via either autoclave leaching or concentrate roasting. With a better understanding of the ore mineralogy, opportunities have arisen for enhancing the commercial viability of Opuwo through the application of tailored metallurgical processes.
It is Celsius' intention to conduct a number of separate and bespoke metallurgical test work studies with different groups with specific expertise.
Celsius MD Robert Gregory said: "The Opuwo Project has the potential to be a world-class source of future cobalt supply. The conclusion of the drill programme to generate ore samples for the commencement of the metallurgical testing and development work programmes is an important step in establishing the feasibility of the Opuwo project. Of note, the identified processing options encompass both low cost and reduced environmental footprint that aligns with the increasing demand for cobalt and copper in electric vehicles."
