Zanaga Iron Ore Company Limited (AIM ticker: ZIOC) is an iron ore exploration and development company, with its flagship asset being the 100% owned Zanaga Iron Ore Project, located in the Republic of Congo. The Government Mining Licence, Environmental Permit, and Mining Convention are all in place for this project.

The Zanaga Iron Ore Project is a globally significant asset with a 6.9 billion tonne resource and 2.1 billion tonne reserve, aimed at 30Mtpa production of high-grade DRI pellet feed with very low impurity levels. A 2024 Feasibility Study confirmed its strong economic viability. When fully developed, Stage One (12Mtpa) and Stage Two (18Mtpa expansion) together could establish Zanaga as one of the largest iron ore mines worldwide. With all key permits secured, Zanaga is well positioned to benefit from increasing demand for high-quality, low-impurity iron ore, utilising low operating costs and an efficient slurry pipeline to the port.

In light of the changes in the world's economy and the increasing demand for low-carbon steel production, the Zanaga Project is well-positioned to become one of the largest producers of high-grade premium DRI pellet feed iron ore concentrate.
