Report summary

NAMISA's mining operations are comprised of two mines, Engenho and Fernandinho, in Minas Gerais state, Brazil. The former is located approximately 40 kilometres south of the city Belo Horizonte, whilst the latter 60 kilometres southwest. In November 2015, CSN and the Asian consortium JKTC concluded a strategic alliance to merge their mining and logistics assets under a new company, Congonhas Minerios. Though production at NAMISA was down over the past few years due to weak market conditions, the mine returned to its more typical run rate in 2017. Because JKTC used to have a 40% ownership stake in NAMISA, CSN used to charge market rates for the operation to use its rail and port infrastructures. With the creation of the Congonhas Minerios joint venture, NAMISA's rail and port costs are now close to Casa de Pedra's ones.
