Vertical and horizontal displacement is continuing at the Nchanga Open Pit Cut 2 in Chingola in Zambia, where geo-technical assessments point to an imminent collapse of a portion of the open pit – but the anticipated slough had not happened by late Sunday when Mining Weekly spoke by phone to Konkola Copper Mines CEO Chris Sheppard. “We’ve got some movement taking place as we speak, and there are signs of displacement vertically and horizontally, but we’re on top of the problem and everything’s under control,” said Sheppard, who is well-known in these parts as AngloGold Ashanti’s former COO South Africa. Sheppard joined Konkola Copper Mines, which is part of the Vedanta Resources group, in March last year.
