* Rio Tinto boosts Q2 iron ore output, shipments
* Sees total 2014 iron ore shipments around 300 mln/t
* Says Q2 was strong, lifts 2014 copper output guidance
(Adds more data, details)
SYDNEY, July 16 World no. 2 iron ore miner Rio
Tinto said expansion work at its mines and
productivity gains led to a sharp rise in iron ore output as it
steps up shipments to Chinese steel mills.
The company, which competes with Vale and BHP
Billiton in the seaborne iron ore market, said
it was on track to produce 295 million tonnes of the
steel-making material in 2014, up from 266 million last year.
Shipments for the year should reach 300 million tonnes.
"Our iron ore expansion continues to deliver high-margin
growth reinforcing our position as a low cost producer," Rio
Tinto said in its second-quarter production report on Wednesday.
Second-quarter iron ore shipments climbed 23 percent on the
same period a year ago to 75.7 million tonnes, while production
of the steel-making ingredient rose 11 percent to 73.1 million,
the company said.
Analysts have begun to question the expansion plans of big
iron ore miners following a market correction tied to a
slowdown in China's economic growth to its weakest in 23 years.
Iron ore for immediate delivery to China .IO62-CNI=SI
stood at $98 a tonne on Wednesday but fell to a 21-month low of
$89 in mid-June.
Rio has longer term plans to raise its output to 360 million
tonnes a year. Vale, the world's largest producer, is also
digging more mines.
BHP is lifting output to between 260 million and 270 million
tonnes from a 217 million tonne target in 2014.
Importers to China are counting on China closing up to a
fifth of its domestic mine production in response to
sub-$100-per-tonne iron ore. This would increase reliance among
mills in China on foreign ore, which contains higher iron
content and can be mined and shipped more cheaply.
Fortescue Metals Group Ltd, Australia's
third-largest iron ore miner, is expected to release data later
on Wednesday confirming it shipped 124 million tonnes of iron
ore in the 12 months to June 30.
Outside of iron ore, Rio Tinto lifted guidance for its share
of mined copper production by 15,000 tonnes to 585,000 tonnes.
It noted strong production from its interests in the United
States, Chile. Mongolia and Indonesia in the second quarter.
