April 14 (Reuters) - A Chinese consortium bought the Las Bambas copper mine in Peru from Glencore Xstrata for $6 billion, the high end of analysts' forecasts in China's biggest acquisition of a mine, showing the strength of its long-term need for copper.
MMG Ltd, the Hong Kong-listed offshore arm of China's state-owned Minmetals Corp, led the winning bid in partnership with Hong Kong-registered Guoxin International Investment Corp and state-owned investment giant CITIC Group.
Commodity trader Glencore had agreed to sell Las Bambas to secure approval from China's competition authorities for its takeover of miner Xstrata. Beijing made this condition to prevent the merged group from having potentially too much power over the global copper market.
A Chinese buyer had been considered a virtual certainty since Las Bambas was put on the block, given the deep pockets of China's state-owned enterprises and its hunger for copper as the world's top consumer of the metal.
Glencore will receive about $5.85 billion in cash upon completion of the deal, which compared with analysts' forecasts between $5 billion and $6 billion. The Chinese group will also pay the mine's capital expenditure and development costs from the beginning of 2014 until the deal closes, which amounted to about $400 million as of March 31.
"In our view, the agreed consideration offers a surprise to the upside ... The transaction is another testament to Glencore CEO Ivan Glasenberg's strong deal-making credibility and the fact that he is willing to play a long game," Bernstein Research analysts said in a note.
"In addition, it underlines the global scarcity of large high-quality copper deposits and the continued Chinese demand for this metal."
The sale, initially expected to be concluded by the end on 2013, dragged on due to a delay in reaching agreement on price.
Glencore said last month the Minmetals consortium was the preferred bidder.
Copper prices are down almost 10 percent on the year. They have recovered some ground since China's first domestic bond default last month raised worries over its credit situation prompting a 9 percent tumble in the price of the red metal.
The Peruvian mine is due to start production in 2015 at a rate of more than 450,000 tonnes a year for the first five years.
KEEP CHINA HAPPY
Rating agency Moody's had signalled that a decision by Glencore to abandon the sale could have put its credit rating at risk.
Swiss-based Glencore said it would use the proceeds from the sale to "immediately and materially" deleverage its balance sheet and could use some to make new acquisitions. It planned to return any surplus cash to shareholders.
If Glencore had failed to sell Las Bambas, Beijing had given it the option to sell one of four other copper projects - Frieda River in Papua New Guinea, Tampakan in the Philippines, or Alumbrera or El Pachon in Argentina.
Glencore has already agreed to sell its stake in Frieda River to Australian copper producer PanAust and is looking for a buyer for its stake in Tampakan, both of which were Xstrata projects.
The miner-trader had signalled that keeping Las Bambas could have been an option, but market sources said failing to sell it after months of negotiations would have irritated China, a vital client for any commodity firm.
The deal is the biggest acquisition ever for MMG, a Melbourne-headquartered producer of copper, zinc, and lead with mines in Australia, Laos and the Democratic Republic of Congo. It aims to rank among the top diversified miners outside of China.
Other companies interested in Las Bambas included Chinese aluminium giant Chinalco and a western consortium made up of Teck Resources, Newmont Mining Corp and private equity firms Blackstone Group and Magris Resources.
The deal, which is expected to close prior to the end of the third quarter, is subject to approval from China's Ministry of Commerce as well as from MMG's shareholders.
China Minmetals Non-Ferrous Metals Co Ltd, which holds about 74 percent of MMG, has agreed to vote in favour of the deal, Glencore said.
Shares in Glencore Xstrata were up 1.1 percent by 1021 GMT, outperforming a 0.4 percent rise in the mining sector. (Reporting by Karen Rebelo in Bangalore and Silvia Antonioli in London; Additional reporting by Sonali Paul in Melbourne; Editing by Tom Heneghan and Jane Baird)
