Black Mountain Mining (BMM), a Vedanta Zinc International (VZI) operation in the Northern Cape, has awarded the establishment and mining of the Gamsberg open-pit zinc operation to Aveng Moolmans, a business unit of Aveng Mining.
The US$400 million Gamsberg project includes set up and commissioning of a concentrator plant and associated infrastructure for the 4 Mt/a run-of-mine open-pit mine on one of the world’s largest undeveloped zinc deposits, some 20 km east of the town of Aggeneys where BMM is based.
Aveng Moolman’s scope of work includes establishing a fleet of mining equipment, workshops, offices, stores and related facilities on site, formation of access ramps, mining of waste material and ore, and hauling to dumps and stockpiles. Additional work includes drilling and blasting, presplit and trimming of final pit walls, forming and maintaining dumps and ore stockpiles, construction of haul roads and implementing dust control measures.
A total of 50,8 million bank cubic metres (BCMs) of waste and ore will be mined over the initial 44-month contract period – comprising 47,9 million BCMs of waste and 2,9 million BCMs of zinc iron ore.
Deshnee Naidoo, VZI Chief Executive Officer, said: “Gamsberg is a key replacement and growth project for VZI. We are excited to have entered into a partnership with Aveng Moolmans, a seasoned industry player to set up and start delivering on the bulk mining.”
Stuart White, Managing Director of Aveng Mining, said: “Our 30-year track record in the mining industry coupled with our extensive experience across the African continent in open-cut, shaft sinking and underground mining projects, including design construction, project management, operations management and logistics, have contributed to the successful award of this project, and we look forward to partnering with Vedanta in delivering quality work”.
Gamsberg currently employees 322 people on site and is expected to yield 250 000 t/a of zinc metal in concentrate. The Gamsberg mine, with a 13-year life of mine, will begin producing first ore in 2018.
