Anglo American (LON:AAL) will boost its giant Minas Rio iron ore mine in Brazil to full capacity after the country’s authorities granted it a key licence for the use of an expanded tailings dam at the site.
Operations at the mine, expected to produce 26.5 million
tonnes of the steel-making ingredient a year, were suspended for eight months
last year following a leak in a pipeline that carries ore to a port in Rio de
Janeiro for export.
The company restarted Minas Rio in December 2018 after repairing the pipeline, but analysts had pointed out that future production would be severely reduced if Anglo were unable to raise the level of the tailings dam.
The newly obtained licence not only allows Anglo to operate the upgraded mine waste storage, but it completes the third phase of mine development, which will take it to full capacity.
Waste disposal is a sensitive issue after a tailings dam
collapsed at a Vale mine in Brazil, killing almost 300 people and destroying the
nearby town of Brumadinho. Brazilian authorities have become stricter in
granting licences for these facilities since.
Anglo said it had built the Minas Rio dam using the
downstream method, which is regarded as safer and can hold more water than the
upstream design.
The world’s number four diversified miner bought the iron
ore project in Southeaster Brazil during the commodity prices boom of
2007-2008, paying local ex-billionaire Eike Batista $5.5 billion for it. Anglo
then spent another $8.4 billion, more than twice what was originally projected,
to bring Minas Rio into production in 2014.
The deal soon soured, as rising global iron ore output
overwhelmed demand, causing prices to tumble 80% from their 2011 peak. The
miner also saw itself forced to write down the value of the asset by about $4bn, underscoring
how the group mistimed its entry into the iron ore sector.
And while prices recovered in 2016 (they climbed
81%), the extreme volatility for most of the year brought
into question whether Anglo’s costly bet for iron ore would or would not
eventually pay off.
Despite the challenges, Anglo said that Minas Rio will
produce 23 million tonnes of iron ore this year.
