Kipushi Cobalt-Copper Tailings Project - Market Update
Highlights
- Engineering Study updated;
- Major equipment packages tendered;
- Concrete works being tendered;
- Design work for Leach Residue Storage Facility awarded.
Australian resources and investment company, Cape Lambert Resources Limited (ASX: CFE) (Cape Lambert or the Company) is pleased to provide an update on the progress at the Kipushi Cobalt-Copper Tailings Project (Project) in the Democratic Republic of Congo (DRC).
The Project is held by Soludo Lambert Mining SAS (Soludo Lambert), under 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.

Figure 1: Project Location
As noted in the CFE June 2018 Quarterly Report, precipitation tests completed produced a mixed hydroxide precipitate (MHP) with copper and cobalt grades ranging from 22.8% - 31.9% and 9.77% - 18.4% respectively. The value of 18.4% cobalt was for a precipitate produced after the removal of copper and indicated that a higher grade cobalt MHP could be produced as an alternative to the mixed copper/cobalt MHP (refer ASX announcement dated 31 July 2018).
Based on this testwork, the Engineering Study recently completed by Minnovo Pty Ltd was updated to provide for the production of a copper-rich MHP and a cobalt-rich MHP separately. The production of separate products is advantages as the copper-rich MHP can be sold to copper focused companies whereas, the cobalt-rich MHP can be sold to cobalt focused companies, therefore, greatly expanding the potential buyer base.
The updated process flow sheet developed by Minnovo is shown in Figure 2.

Following the commencement of the detailed design by Minnovo, tenders for the major pieces of equipment (thickeners, filter presses, horizontal belt filter, SO2 scrubber and clarifier) were issued, with responses due back shortly.
Soludo Lambert has issued the tender document for the concrete works at the leaching plant to four reputable companies operating in the DRC, with proposals due at the end of August 2018.
Soludo Lambert has also awarded the design of the leach residue storage facility (LRSF) to Golder Associates Africa, with a site visit to occur shortly to undertake geotechnical investigations at the proposed LRSF location.
Cape Lamberts Chairman, Tony Sage, said I am very pleased that the updated Engineering Study has provided for the production of separate cobalt-rich and copper-rich MHP products that we anticipate it will attract a much wider market of buyers and that the engineering design works are progressing with equipment and construction works out to tender.
Yours faithfully
