ShapshotNewtrax has collaborated with Kamoto Copper Company SA (KCC), deploying its state-of-the-art Proximity Detection Technology (PDT) at Kamoto underground copper and cobalt mine (KTO).

PDT is the system flawlessly, with no lost time incidents and on schedule, paving the way for advanced proximity detection and operations management. With phase two commencing it will synchronize with our Mining Data Platform providing KCC with a real-time view of their underground operations.

The copper-cobalt minerals hosted in rocks of the Neoproterozoic Katangan Basin in the Central African copper belt metallogenic province of the DRC are a classic example of (low energy) sediment-hosted stratiform copper (SSC) ore system deposits. These deposits are economically significant, as they account for approximately 25% of the world’s copper production and known Mineral Reserves being second only to porphyry copper deposits in terms of copper production and the most important global cobalt resource.

The copper-cobalt deposits contained in a sedimentary series of rocks are known as the Mines Group in the Katanga sequence and the Roan Group in Zambia. The sediments are shallow-water shales, dolomitic shales, reefal dolomites and possible evaporitic lagoonal mudstones, formed on a platform marginal to a subsiding basin. The rocks are exposed in a series of tightly folded and thrusted anticlines and synclines, which generally trend east-west or southeast and are often overturned to the north. In spite of this deformation overprint, the mineralized zones, although sometimes lenticular along strike and down dip, as well as showing local diapiric forms, display remarkable large-scale continuity within the Mines Group.

KTO UG operations extract mineralized copper ore from the Kamoto deposit, which is differentiated from KTE, predominantly mined in the KOV OP, but contains the same lithologies. The KTO UG is subdivided into five fragments as follows:
Principal: forms a rough L-shape syncline, flat lying to gently dipping (up to 8° to the north) in the central and northern areas and becoming steeper (15° to 25°) towards the east and west flanks. The steeply dipping area to the south is sub-vertical in places and is separated from the flatter dipping area by structurally complex zones and RAT Lilas waste intrusions.
Etang South: forms a broad open synform dipping 25° to 35° to the east on an approximate north northwest strike;

Etang North: forms a roughly rectangular slab dipping 35° to 55° to the east on an approximate northnortheast strike. It extends below the Principal fragment in the north;

Ecaille Renversee: a small reversed fragment between Principal and Etang North; and

Pringle: forms a moderately open synform dipping 35° to 55° to the southeast on an approximate north strike.

Primary mineralization, in the form of sulphides, within the Lower Roan is associated with the DSTRAT and RSF for the OBI and the SDB and SDS for the OBS and is thought to be syn-sedimentary in origin. Typical primary copper sulphide minerals are bornite, chalcopyrite, chalcocite and occasional native copper while cobalt is in the form of carrolite. The mineralization occurs as disseminations or in association with hydrothermal carbonate alteration and silicification. Supergene mineralization is generally associated with the levels of oxidation in the subsurface sometimes deeper than 100 m below surface. The most common secondary supergene minerals for copper and cobalt are malachite and heterogenite.

Crushers and Mills

Milling equipment has not been reported.


The mixed ore milling consist of CM1 and BM1 (or CM2 and BM2), CM5, CM6 and BM6, CM7 and BM7 milling circuits.

The CM1/BM1 (or CM2/BM2) mills are operated in a closed circuit with a common cyclone clusters. CM5, CM6/BM6 and CM7/BM7 also have the same arrangement. All circuits will produce a grind of 80% -150 µm from a feed with an F80 of 150 mm. BM1/BM2, CM5, BM6 and BM7 operate with a ball load of up to 35%.

The feed to each mill circuit is measured and recorded using a weightometer installed on each AG or SAG mill feed conveyor. Process water, together with the crushed ore, is added to each AG or SAG mill to achieve a slurry solids content of 75% by mass within the mill. Scats conveyors are installed at the discharge of CM5, CM6 and CM7 to remove material from the milling area to a dedicated stockpile outside the building.
