Simandou: Economic and fiscal impact

Simandou presents Guinea with an opportunity for economic tranformation. The first step to ensure it is not missed is to understand its potential direct contribution to the Government's revenues.

The analysis below presents estimates based on (1) project data published by Rio Tinto in Dec 2023, (2) Rio Tinto's financial results for 2024 published in Februrary 2025, and (3) the IMF's Fiscal Analysis of Resource Industries model. All these inputs are publicly available.

The results and model below have been shared for comment with the Government of Guinea, the mining companies and other experts. Any errors remain the responsibility of the author.

Simandou: Environmental and Social Impact Assessment

Rio Tinto published the complete Environmental and Social Impact Assessment (ESIA) for the Simfer mine and rail spur in April 2024. The non-technical summary is available to download from their website (button below redirects there), but the complete document while publicly available was harder to access. I have therefore uploaded all chapters to this page. I confirmed in advance with Rio Tinto that I could share.

The non-technical summary for the Simfer port is also available from the Rio Tinto website linked below.

If I gain access and authorisation to share the WCS ESIA I will also make it available here.
