Vedanta Zinc International subsidiary has delivered strong zinc production at Black Mountain in the Northern Cape and at Skorpion in Namibia in the last quarter of 2017.
In addition, the company also reported that the $400-million Gamsberg zinc project was on track for first production in mid-2018.
Black Mountain recorded its highest quarterly metal-in-concentrate production in the last four years of 21 000 t.
Construction of the concentrator is under way at Gamsberg, with cold commissioning expected in the first quarter of the company’s 2019 financial year and power and water infrastructure 90% complete. Eventual full production of 250 000 t/y is earmarked.
Seventy percent of Gamsberg’s pre-stripping is complete and a 500 000 t ore stockpile is targeted ahead of first feed. Waste stripping is expected to be fully complete by the fourth quarter of the company’s 2019 financial year.
At Skorpion, the pit 112 extension project is progressing and waste stripping is expected to be fully complete by the fourth quarter of the company’s 2019 financial year.
First ore was extracted ahead of schedule in November 2017 at a project that will increase Skorpion’s mine life by another 2.5 years and contribute 250 000 t of metal over that period.
Vedanta acquired zinc assets, including Gamsberg, from Anglo American in 2010 for $1 338-million.
