Origin of Material
The material was sourced from the Sentinel Copper Mine owned by Kalumbila Minerals Limited (KML), a First Quantum subsidiary. The Sentinel copper mine is situated on the southern portion of the Trident copper project area. The mine is a strata bound, sediment hosted copper-nickel-cobalt deposit. Sentinel is approximately 150 kilometers west of the town of Solwezi in Northwestern Province of Zambia.
Approximate Mineral and Chemical Composition
The Sentinel copper deposit is a structurally modified sediment hosted copper deposit. Copper mineralisation is hosted within a phyllite package. Copper mineralisation is dominated by chalcopyrite which occurs as fine to coarse disseminations and or veinlets, with extensive zones of pyrite, particularly in the hanging wall, and with pyrrhotite occurring throughout. The copper sulphides are focused in a relatively carbon-rich zone in the center of the phyllite hosted orebody. The host phyllite is very fine grained, with quartz, muscovite, biotite and iron sulphides present.
