Global miner Rio Tinto reported an 11 percent rise in annual iron ore shipments on Tuesday, roughly in line with its full-year guidance of 340 million tons, and said it expected to boost production and shipments in 2016.

Rio's strong output, low costs and sharp cuts in capital spending are expected to help it maintain or raise its dividend at least for the next 12 months, in stark contrast to its rivals, even with commodities prices mired at multi-year lows.
