MELBOURNE, Feb 14 (Reuters) - China's state-owned CITIC Group has bought a A$452 million ($467 million) stake in Australia's Alumina Ltd, giving it an interest in the world's largest alumina business at a time when China has grown more dependent on alumina imports.
Alumina's shares jumped 17 percent after the share sale was announced, on relief that the company has been shored up by a strategic investor, allowing it to pay down debt as the aluminium industry struggles with weak prices.
"This takes all the pressure off them," said Hayden Bairstow, an analyst at CLSA.
Alumina owns 40 percent of Alcoa World Alumina & Chemicals (AWAC), the world's top producer of alumina, in a joint venture with U.S. aluminium giant Alcoa.
CITIC, through its listed arm CITIC Resources Holdings and another subsidiary, will own 13 percent of Alumina following the placement, in a deal that has already won approval from the Australian and Chinese governments.
Under the terms of the agreement, the Chinese firm will be allowed to raise its holding to 15 percent and is capped at that level for two years. Beyond that it will be allowed to raise its stake to just below 20 percent.
Alumina said it would use the funds raised to pay down debt at a time when the aluminium industry has been struggling with rising energy costs and weak prices, largely due to unanticipated growth in aluminium production in China.
China has had to increase imports of alumina after Indonesia last year clamped down on exports of bauxite, which is used to produce alumina, which is then turned into aluminium.
"CITIC's investment demonstrates their confidence in the alumina industry and their understanding of Alumina Limited's unique position in the global market," Alumina Chief Executive John Bevan said in a statement.
CITIC agreed to pay A$1.235 a share for the stake.
Alumina's shares surged to a 14-month high of A$1.405 after the announcement and last traded up 12 percent at A$1.34 in a flat broader market.
The struggling aluminium industry won another fillip this week when Rio Tinto agreed to keep open its Australian Gove alumina refinery, after securing gas supply from the Northern Territory government, crucial to cutting costs at the loss-making plant.
CITIC Resources already owns a direct 22.5 percent stake in AWAC's Portland aluminium smelter.
It previously owned a 25 percent stake in Macarthur Coal, and played a pivotal role in extracting a solid premium when the Australian miner was taken over by U.S. firm Peabody Inc in 2011, booking a A$400 million profit on that investment.
Alumina was advised by Flagstaff Partners, and CITIC was advised by ANZ Corporate Advisory.
