(a)Robe River Mining Co. Pty. Ltd. (which is 60% owned by the Group) holds a 30% economic interest in Robe River Iron Associates (Robe River). North Mining Ltd (which is wholly owned
by the Group) holds a 35% economic interest in Robe River. Through these companies the Group recognises a 65% share of the assets, liabilities, revenues and expenses of Robe
River, with a 12% non-controlling interest. The Group therefore has a 53% economic interest in Robe River.
(b)Iron Ore Company of Canada is incorporated in the US, but operates in Canada.
(c)Rio Tinto SimFer UK Limited (which is wholly owned by the Group) holds a 53% interest in SimFer Jersey Limited (SimFer Jersey), a company incorporated in Jersey. SimFer Jersey, in
turn, has an 85% interest in SimFer S.A., the company that will carry out the Simandou mining operations in Guinea and an 85% interest in the company which is delivering SimFer
Jersey’s scope of the co-developed rail and port infrastructure. SimFer Jersey at present has a 100% interest in the companies that will own and operate the transhipment vessels,
however this is anticipated to reduce to 85% with the Government of Guinea taking a 15% interest before transhipment operations commence. These entities, together with the equity
accounted WCS Rail and Port Holding Entities described in note 33, are referred to as the Simandou iron ore project.
