[5] The BBC reported seeing leaked documentation verifying spillage of sulphuric acid and other toxic chemicals polluting water sources belonging to people living near the mine.

[6] The whistle-blower, who worked for 15 years with KCM, alleges that since Vedanta bought the mine in 2004, corners have been cut to save the costs of running operations.

The area at risk represented a 350 metre length of the edge of the pit, with 20 million tonnes of material expected to fall.

[6] The open pits at Nchanga Mine are situated in a crescent-shaped structure 11 km long around the municipal town of Chingola in Zambia.

At present, mining is concentrated on the main Nchanga pit, with satellite planned for future extensions, as economics and processing technological developments unfold.
