Simandou project

Unlocking the world’s largest known high-grade iron ore deposit

About Rio Tinto

A project of national importance for Guinea and a resource of critical significance in reducing carbon emissions from direct reduction steel production, Simandou is a project of extreme rarity, and its time is now.

Operating in Guinea as Rio Tinto Simfer, we are committed to delivering on the long-held promise of the Simandou iron ore project. Along with our joint venture partners and the Government of the Republic of Guinea, we are privileged to be bringing to life a one-of-a-kind mining megaproject that will unlock some of the highest-grade, low impurity iron ore to be found anywhere in the world.

With Simandou’s extensive mineral deposits and the infrastructure needed to bring them to market, the project’s economic potential will not only benefit those directly involved, but will seed and deliver economic development potential for Guinea and its people for generations to come.

Rio Tinto Simfer

Rio Tinto is the majority shareholder and managing partner of Rio Tinto Simfer (SIMFER S.A.) – a joint venture between Rio Tinto (45.05%), CIOH (39.95%) and the Government of the Republic of Guinea (15%). In partnership, we are responsible for developing blocks 3 and 4 of the iron ore mining concession known simply as the Simandou project.

Together with Winning Consortium Simandou (WCS), developers of blocks 1 and 2 of the Simandou mining concession, we are also in partnership with the Government of the Republic of Guinea to co-develop the infrastructure necessary to export mined iron ore from the far southeast of the country to Guinea’s maritime borders and beyond.

Rio Tinto Simfer operates in full alignment with Rio Tinto’s global standards, practices, policies and procedures. It is our vision that working closely and transparently with our partners, stakeholders and local communities, we will deliver on the promise of the project Simandou to exacting international standards in operational health and safety, governance, social wellbeing, and environmental stewardship.
