The capital projects comeback

The Canadian Environmental Assessment Agency and the Ontario Ministry of Environment and Climate Change have separately okayed the project.

The Australian junior iron ore producer is also studying whether it needs to write down the value of any ­assets ahead of next month’s half-year result.

The decision caps off a dreadful month for South Australia’s mining sector.

The miner also said it aims to increase sales by 1% percent in 2015, taking advantage of rising production and using offtake from its stock.

The technique, known as biomining, is already being tested here on Earth as a sustainable treatment of ores and mine waste.

The Saskatoon-based miner also hiked its quarterly dividend 9% to 38 cents per share.

The firm expects production at Ferrobamba, one of the four deposits that make up Las Bambas project, to start early next year.

The firm became the first major mining company to openly accept the toll that slumping commodity prices are taking on the global industry.

The miner, one of the biggest exporters of South African coal, may re-open those operations if economic conditions improve.
