Capital of R2.3-billion will be spent over 14 years on the Burnstone gold project, in Mpumalanga, where two-million ounces of gold are to be mined over 21 years, Sibanye-Stillwater CEO Neal Froneman told the BMO conference this month.
Sibanye-Stillwater acquired the Burnstone project from Wits Gold for R1 in 2015.
“It was a project that did not work. We believe there were very substantial misunderstandings of the geological model. We have a proper sedimentary geological model.
Myself and my team know how to mine Kimberly reefs. They are very channelised and certainly we believe that we’ll bring this to account successfully,” Froneman stated in a YouTube video rendition covered by Engineering News & Mining Weekly.
The average steady-state production is expected to be 138 000 oz/y and the current average operating cost R415 866/kg.
“So, there’ll be very significant margins as well,”said Froneman.
At assumed prices, payback is seven years, net present value R1.4-billion and the internal rate of return 24%.
“Again, a great opportunity for our shareholders from a value accretion point of view,” he added.
It is a shallow mine with an average depth of 550 m.
Infrastructure put in place by previous owners includes a functional metallurgical facility, an established tailings storage facility, an equipped vertical shaft and a functional trackless decline shaft, extensive underground development and surface offices, workshops and compressors.
“Very pleasingly, the project provides very substantial regional social and economic benefits. The Balfour community is an impoverished community with very significant unemployment and the mine will provide 2 500 long-term jobs and meaningful opportunities for local procurement participation,” Froneman said.
The original owner of the South Rand-located Burnstone – Great Basin Gold – reported trial mining getting under way at Burnstone in October 2009, after the Kimberly Reef had been accessed underground from the main decline and had also been intersected in the vertical shaft.
