BHP Billiton has extended off-take contracts with Mincor Resources, agreeing to purchase nickel ore concentrate from Mincor’s Western Australia mines once it has been treated at the BHP-owned Kambalda mill.

The ore tolling and concentrate purchase (OTCP) agreements, which have been in place since 2001, have been extended by nine years.

The companies signed separate OTCP agreements over four of Kambalda tenements in Western Australia, which were set to expire in February 2010, Mincor said.

Mincor managing director David Moore said he was pleased that BHP Billiton had chosen to renew the contracts.

“These agreements have proved both workable and durable and have provided Mincor with long-term marketing certainty, reduced processing risk and significant operational flexibility,” Moore said.
