BHP says electric vehicle manufacturers are not yet willing to pay a “green premium” to recognise the sustainability credentials of nickel mined in Australia, at a time when surprisingly large volumes of Indonesian nickel have dragged down prices for the metal to a two-year low.

BHP’s chief development officer Johan van Jaarsveld said the company would maintain a policy of only investing in the sort of “sulphide” nickel geology that occurs in Australia and Canada, but was bracing for more nickel supply growth from Indonesian miners working in “laterite” geology.
