Taseko has been in confidential discussions with Sojitz regarding the potential purchase of their interest in Cariboo. No binding agreement has been reached at this time.

The annual payments would consist of a guaranteed minimum payment and additional contingent payments dependent on Gibraltar copper revenues. The modest initial payment would be funded with available cash on hand, and the subsequent annual payments are expected to be funded from cashflows from the acquired 12.5% interest in Gibraltar.

Definitive agreements have not been finalized or signed, and the transaction remains subject to various board, regulatory and other approvals. There is no assurance at this time that a binding transaction will be entered into or completed.
