Deposit Type

  • Sediment-hosted
  • Stratabound


Summary:

Sentinel is located to the southeast of the Trident Project area. The deposit is hosted within structurally thickened, northwest dipping carbonaceous meta-pelitic rocks known as ‘Kalumbila phyllite’.

The Sentinel deposit is a sediment-hosted stratiform copper deposit. Mineralisation is predominantly primary sulphide copper, with sheet-like horizons of ore dipping north at 20-30o . The mineralisation is parallel to dominant foliation, within the structurally deformed carbonaceous phyllite host.

Copper mineralisation at Sentinel is limited to the strongly deformed phyllite unit, with rare lowgrade mineralisation extending only 1-2 metres into the hanging and foot-wall from the contact. The ore-body strikes approximately east-west for 11 km and mineralised horizons dip 20 to 30 degrees in a northerly direction, generally parallel to the dominant foliation.

The dominant copper-bearing mineral is chalcopyrite and typically occurs within bedding/foliation parallel quartz-kyanite-carbonate mm-scale veinlets. Within folded zones, veinlets tend to be thicker (mm scale), blebby, and more irregular, and often contain a relatively higher proportion of chalcopyrite. Late sulphide-bearing cross-cutting veinlets and disseminated or blebby chalcopyrite are less common.

The oxidised horizon, up to approximately 70 m in depth, contains non-primary sulphide Cuminerals, predominantly chalcocite, and tarnished chalcopyrite. The top 5-15 metres from surf ........


Mining Methods

  • Truck & Shovel / Loader


Summary:

The Sentinel Pit is being mined in a series of terraced phases, using large-scale mining equipment, and with mining costs expected to be minimised through the adoption of bulk mining and ore handling methods featuring electric shovels and drill rigs, trolley-assisted (TA) haulage, and in-pit primary crushing and conveying (IPCC). Waste and ore haul cycle times, and hence fuel consumption, are expected to be reduced through the adoption of TA and IPCC.

Open pit mining at Sentinel commenced in two surface box-cut areas of the Phase 1 Pit; ie, in the north west boxcut in April 2013, and then in the south boxcut from early 2014. Since 2013-2014, mining has proceeded in the Phase 1 pit to a current depth of approximately 200 m.

The Phase 2 pit, immediately to the east, was progressively cleared and grade control drilled from 2016. Mining from the southern pit crest limits, 800 m across to the Musangezhi River, now extends along a strike length of 1.2 km and to a depth of approximately 25 m.

Mining capacity will eventually increase to around 68 million bcm of ore and waste mined per annum. The ultimate 5.7 kilometres long, 1.5 kilometres wide and 390 metres deep pit is being mined in stages, with ore crushed in-pit and conveyed overland to the Sentinel process plant.

Four in-pit crushers and associated in-pit and overland ore conveyors have now been installed and are operational. The surface conveyors extend across to the plant crushed o ........
