Report summary

Corumba is a small surface mine in Mato Grosso do Sul state, Brazil. It is 100% owned and operated by MMX, a subsidiary of the EBX group. In July 2013, MMX stopped production at Corumba citing the need to optimise capital. Though the suspension was initially estimated to last just six months, MMX continues to struggle financially and, as such, we've assumed the mine will remain permanently idled.Corumba used to produce a mix of lump and fines that were sold to nearby iron and steel producers as well as export customers.
