Macro Metals (M4M, formerly Kogi Iron and before that was Energio), is a Perth-based company with the objective of becoming an African iron ore producer through the development of its 100%-owned Agbaja iron ore project in Kogi State, Republic of Nigeria, West Africa.
The company completed a Preliminary Feasibility Study which determined that the development of an iron ore mining and processing operation at Agbaja to produce 5 Mtpa of upgraded iron ore concentrate was technically and economically viable.
The company changed its name from Energio to Kogi Iron in November 2012, and then to Macro Metals in December 2022.
