Report summary

Corumba is a small surface mine in Mato Grosso do Sul state, Brazil. It is 100% owned by MMX, a subsidiary of the EBX group. In July 2013, MMX stopped production at Corumba citing a need to optimise capital. Though the suspension was initially estimated to last for six months, MMX continues to struggle financially and production has yet to restart. Corumba used to produce a mix of high grade lump and fines for both export customers and domestic iron ore and steel producers.
