The contract for the establishment and mining of the Gamsberg open-pit zinc operation has been awarded to Aveng Moolmans, a subsidiary of Avenge Mining, by Black Mountain Mining (BMM), a Vedanta Zinc International operation in the Northern Cape.
The $400 million Gamsberg project includes set up and commissioning of a concentrator plant and associated infrastructure for the 4 Mtpa run-of-mine open-pit mine on one of the world’s largest undeveloped zinc deposits, located 20 km east of the town of Aggeneys.
Aveng Moolman’s scope of work includes the establishment of a fleet of mining equipment, workshops, offices, stores and related facilities on site, the 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 50 822 079 bank cubic metres of waste and ore will be mined over the initial 44-month contract period – comprising 47 887 780 bank cubic metres of waste and 2 934 299 bank cubic metres of zinc iron ore.
“Gamsberg is a key replacement and growth project for Vedanta Zinc International. 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,” says Vedanta Zinc International CEO Deshnee Naidoo.
Aveng Mining MD Stuart White says that the company’s 30-year track record in the mining industry coupled with its extensive experience across the African continent in open-cut, shaft sinking and underground mining projects, have contributed to the successful award of this project. “We we look forward to partnering with Vedanta in delivering quality work,” he said.
Gamsberg currently employees 322 people on site and is expected to yield 250 000 tpa of zinc metal in concentrate. The Gamsberg mine, with a 13 year life of mine, will start producing concentrate in 2018.
