The Trident project, located approximately 150 kilometres west of Solwezi in north-west Zambia, is comprised of the Sentinel copper mine and the Enterprise nickel project.

In May 2012, the Company’s Board approved construction of the Sentinel copper project. Construction activities were completed in 2014 and first physical production was realized in February 2015.

Mining and Processing

Sentinel’s processing facility has a target throughput rate of 55 million tonnes per annum of ore at an average grade of 0.51% copper. Annual production is expected to range between 280,000 tonnes and 300,000 tonnes of copper.
Ore is crushed in-pit and conveyed overland and onto a crushed ore stockpile ahead of two milling trains, each comprising a SAG mill and a single ball mill. Each train consists of five banks of flotation cells. Final concentrate at a grade of 24% copper will be thickened and filtered in a dedicated concentrate handling facility.
