South African mines will not be nationalised despite "noises" from some politicians, South Africa's central bank Governor Tito Mboweni said on Saturday.
However, he warned in a memorial lecture that authorities in emerging countries must guard against excessive foreign ownership of banks.
Some politicians, including those from influential trade unions and the ruling ANC party's youth, have repeatedly called for government to take over ownership of the country's mines, a move that could scare off investors.
