The Global Iron Ore Mines Tracker (GIOMT) provides information on global iron ore mines, and includes all operating, proposed, shelved, retired or mothballed mines since 2023. The GIOMT provides asset-level data on ownership structure, development stage and operating status, annual production since 2022, and design capacity for each mine.
Each iron ore mine varies in terms of size and infrastructure. The majority of iron ore mine assets are reported individually, but in other scenarios several mines may be reported together under a larger mining complex when more granular data is unavailable. The GIOMT typically does not capture historic data on mining assets retired prior to 2023. Each iron ore mine is linked to its own separate factsheet on GEM.wiki, which provides additional details.
The first release of this data was in November 2024, followed by a limited update for new and retired assets in August 2025.
