Work is progressing with Rio Tinto's project partner, Chalco, on obtaining required Simandou regulatory approvals, which, once granted, will trigger formation of an agreed Rio Tinto-Chalco joint venture. Finalization of an infrastructure investment framework, expected in early 2012, will also trigger the requirement for the government of Guinea to contribute its share of infrastructure project expenditure incurred to that time.

The new funding brings the total amount spent upon or committed to the Simandou project to $3 billion, including the $700- million settlement payment to the government (E&MJ, May 2011, p. 18). Of this amount, approximately $2 billion has been allocated to mine-related costs and $1 billion to infrastructure requirements.

The Simandou project is currently held by Rio Tinto subsidiary Simfer, whose shareholders are Rio Tinto (95%) and the International Finance Corporation (IFC), a member of the World Bank Group (5%). Once the joint venture agreement with Chalco is complete, Rio Tinto's 95% interest in Simfer will be held by the joint venture, with Chalco acquiring a 47% interest in the joint venture by providing $1.35 billion on an ongoing earn-in basis.

Rio Tinto's agreement with the government grants the government the right to take up to a 35% interest in the Simandou project under specified conditions over a period of 20 years. As the government stake increases, the ownership of other shareholders will be reduced proportionally.

A new rail line through Guinea and a new Guinean port will be constructed to serve the project.
