Cape Lambert Resources Limited: Kipushi Copper-Cobalt Project Leaching Engineering Study Completed
(firmenpresse) - Kipushi Copper-Cobalt Project Leaching Engineering Study Completed
- Engineering Study on Kipushi Leaching Plant completed;
- Metallurgical testing shows recoveries of 90% for copper and 85% for cobalt achievable;
- Board of Soludo Lambert Mining SAS decide to proceed to build the Kipushi Leaching Plant.
Australian resources and investment company, Cape Lambert Resources Limited (ASX: CFE) (Cape Lambert or the Company) is pleased to announce that an Engineering Study for a leaching plant at the Kipushi Cobalt-Copper Tailings Project (Project) in the Democratic Republic of Congo (DRC) was recently completed by consultants Minnovo Pty Ltd (Minnovo).
The Engineering Study was undertaken following the excellent results achieved from a leach testwork program at the Project, with recoveries of 90% for copper and 85% for cobalt being achieved from laboratory scale testwork undertaken to date.
The Project is held by Soludo Lambert Mining SAS (Soludo Lambert), which is a 50/50 joint venture arrangement with local entity Paragon Mining SARL (Paragon) and Cape Lambert.
The Project involves the reprocessing of copper-cobalt tailings contained in the Kipushi Tailings Storage Facility (TSF) located near the town of Kipushi approximately 25km from Lubumbashi, refer Figure 1.

The tailings will be processed through a newly built 1Mtpa acid leach plant, adjacent to the existing flotation plant, designed to produce a mixed hydroxide precipitate (MHP) product.
The process flow sheet developed by Minnovo based on the testwork completed is shown in Figure 2.

Based on the preliminary details delivered by Minnovo prior to the completion of the Engineering Study the Board of Soludo Lambert made a decision to pursue construction of the leaching plant and appointed Minnovo in May 2018 to undertake the detailed design.
Cape Lamberts Chairman, Tony Sage, said I am very pleased that we pursued the leaching alternative to process the Kipushi tailings, as the recoveries for the leaching are far superior than achieved with the existing flotation plant. Preliminary details from the Engineering Study provided the basis for the decision to build the plant, which will be done in earnest to capitalise on the current high price for cobalt.
Yours faithfully
