SYDNEY, April 15 (Reuters) - Rio Tinto's iron ore shipments fell 8 percent in the first-quarter from the previous quarter due to weather-related disruptions in Australia and Canada, but the miner said it was on track to meet its full-year target.
Production still jumped 16 percent on the same quarter a year ago as the world's No. 2 iron ore producer behind Brazil's Vale ramps up production at its Australian mines to meet growing demand from China.
"It appears they were hit a litle harder than we expected by the weather, though we don't see any issues in meeting their full-year target," said RBC Capital Markets analyst Chris Drew.
Iron ore has replaced other industrial and precious commodities such as coal, gold and silver as the mineral with the most profit potential, delivering bumper earnings for giant low-cost miners such as Rio and BHP Billiton.
Iron ore prices .IO62-CN=SOI have recovered 12 percent since a steep dip in March on weaker Chinese steel prices. At the current price of $117 a tonne, Rio Tinto enjoys a profit margin of over $60 a tonne.
Rio Tinto Chief Executive Sam Walsh has repeatedly deflected criticism the company is too dependent on iron ore - accounting for almost half of the company's 2013 revenue - saying China will continue to buy all the ore it can mine for years to come.
Walsh was promoted to chief executive in 2013 to whip the company into shape following disastrous investments in aluminium and coal that led to $14 billion in write-offs.
Rio Tinto said its Iron Ore of Canada division was hit by a colder-than-average winter, which disrupted mining in Labrador over the quarter, while port closures due a cyclone late last year reduced shipments in Australia, the company said.
Overall iron ore shipments in the first quarter came in at 66.7 million tonnes.
Rio said it was on track to meet its target of mining ore at the rate of 290 million tonnes a year and maintained its 2014 production target of 295 million tonnes.
It planned to draw on its Australian stocks of iron ore to increase shipments ahead of production, with around 5 million tonnes of inventory drawdown expected in 2014.
Iron ore of Canada (IOC) is 59 percent owned by Rio Tinto, 26 percent by Mitsubishi Corp and 15 percent by Labrador Iron Ore Royalty Co.
Rio Tinto put its stake in IOC up for sale about a year ago but offers came in well below the mining group's target of about $3.5 to $4 billion, sources said.
Production of 295 million tonnes in 2014 would keep Rio Tinto ahead of rivals BHP Billiton and Fortescue Metals Group, which report quarterly data on Wednesday.
BHP is also expected to show lower shipments in the March quarter after Cyclone Christie barreled into Australia's Pilbara iron ore belt in late 2013 disrupting rail and port shipping operations into January.
UBS forecasts BHP's Australian operations, including shares to joint venture partners will see a modest drop in first quarter production to 53 million tonnes against 53.6 million in the fourth quarter. (Editing by Richard Pullin)
