The ANC has decided not to pursue the nationalisation of mines, national executive member Enoch Godongwana said on Friday.
"Nationalisation was discussed [at the conference], but it was not part of the mining section," he told reporters at the ANC policy conference in Midrand.
"It was discussed broadly as to whether we should retain nationalisation as an option or not. The greater consensus was that there should be a greater state intervention."
Godongwana said details on the proposal for a mining super-tax were not finalised at the conference.
"In principle, the proposal of using some form of... a tax instrument was agreed, but not that [super tax].
The policy discussion document proposed a 50 percent super-tax on profits exceeding about 15 percent. Such a tax could be expected to yield about R40-billion a year at current prices.
