Arc Minerals LTD (LON:ARCM) has completed construction of a pilot plant at the Kalaba copper project in Zambia.
The plant has now been commissioned and has produced a copper-cobalt sulphide concentrate.
Arc is now working out plans for the oxide component of the Kalaba project.
Initial production will incur no mining cost as the plant feed will be drawn down from the existing stockpile of 10,000 tonnes of material grading 2% copper.
The potential to enhance revenue streams through the production of separate copper and cobalt sulphide precipitates is also being investigated.
"I am very pleased to report that we delivered on our commitment to complete the construction and commissioning of the small-scale demonstration pilot plant at Kalaba,” said Nick von Schirnding, Executive Chairman of Arc Minerals.
“We have now completed the plant under budget - for less than half a million dollars. It is also an important step regarding Zamsort's previous commitments in terms of its exploration licenses. In the meantime, we have made major progress regarding our next phase of exploration and our newly identified targets. A more detailed update on this will be made shortly."
