Basic Assessment Report for the Pella Bulk Water Pipeline Upgrade

September 02, 2020

Black Mountain Mining (Pty) Ltd, part of Vedanta Zinc International (VZI), owns and operates the Gamsberg Zinc Mine. In 2010 Vedanta Resources, the holding company of VZI, acquired Black Mountain Mining (Pty) Ltd from Anglo American as part of the sale of Anglo American’s zinc assets. The mining activities commenced in June 2016 when overburden stripping for the open pit commenced. 

Water is currently sourced from the Orange River through an intake pump house located at Pelladrift, almost 30 km to the north east of the Gamsberg Zinc Mine. The current water demand, with the Black Mountain Mine operation and Phase 1 concentrator plant at Gamsberg, is 28 ML/day, the existing intake water pumping system has been designed for 40.8 ML/day. In order to ensure that the pipeline capacity will meet the future water demand and allow for the complete utilization of the currently licensed abstraction volume of 44 ML/day Black Mountain Mining (Pty) Ltd, in conjunction with Sedibeng Water, is proposing to replace and upgrade the existing old underground pipeline and associated infrastructure. This new pipeline will be located within the existing servitude and will supply water to the proposed Gamsberg Smelter Project and existing Gamsberg Zinc Mine, Black Mountain Mine and the surrounding towns (including Aggeneys, Pella, Pofadder and local landowners).

SLR Consulting (South Africa) (Pty) Ltd (SLR) has been appointed to undertake the Basic Assessment (BA) process for the proposed water infrastructure upgrades.
