Under the terms of the agreement, total cash consideration consists of US$230 million to be paid to BHP after closing of the transaction (subject to customary closing adjustments), plus approximately US$40 million in proceeds from the post-closing sale of certain Cerro Colorado copper inventory, and a contingent payment of up to US$50 million to be paid in the future, depending upon copper price performance.

The sale is subject to financing and customary closing conditions, and is expected to close during 4Q18.
