UPDATE 3-Anglo promises austerity after posting first loss in a decade
* Dividend up 15 percent, above expectations, helps shares
* 2012 operating profit down 44 percent, underlying earnings down 54 percent
* 2012 pre-tax loss of $239 million
LONDON, Feb 15 (Reuters) - Anglo American slid to its first net loss for more than a decade in 2012 after profits fell across all units and the global miner wrote $4 billion off the value of its flagship Minas Rio iron ore project in Brazil.
Anglo, like rival Rio Tinto a day earlier, promised caution in future spending. Its 44 percent drop in operating profit to $6.2 billion was expected, but the impairments linked to Minas Rio and Anglo's bruised platinum unit resulted in a net loss, or loss attributable to shareholders, of $1.5 billion.
Minas Rio, where delays and permit troubles have driven costs to more than three times original estimates, has been seen as Anglo's most significant failure of recent years. Anglo had already said last month that it would write $4.6 billion off the value of both Minas Rio and platinum projects.
The miner sought to pacify investors with a 15 percent increase in its dividend which helped lift its shares on Friday, though it cautioned future increases would be tempered by its spending plans.
Anglo's spending is expected to peak this year at between $7.5 billion and $8 billion, thanks to costs at Minas Rio and Australian coking coal project Grosvenor. That will ease to between $6.5 and $7 billion in 2014 as the miner progresses to new projects including copper operation Quellaveco in Peru.
Departing chief executive Cynthia Carroll, one of several mining executives to have fallen foul of investors angry over perceived errors and poor returns, said she had no regrets.
"We did not go after a huge acquisition, or an enormous company. We did not have attempted acquisitions and then failed acquisitions, like some of our competitors. What we did do, and this was the mandate I was given when I arrived, was to pursue iron ore," she told reporters.
"Minas Rio is a resource that has increased fourfold since we have gone into it and it is going to be bigger. The quality of this resource is phenomenal."
Carroll, who departs at the end of next month to be replaced by AngloGold Ashanti's Australian boss Mark Cutifani said: "We will have to be that much more selective about where we are going to spend our money. The shareholders have spoken, it is clear they are looking at the very short term and we have to strike the right balance."
Projects like Quellaveco and coal asset Revuboe in Mozambique, being built from scratch, have come under scrutiny after the expensive overruns at Minas Rio and rival Rio's costly mistakes at its own operation in Mozambique. But Anglo promised it would proceed with care, adding partnerships would be considered for complex, greenfield projects to reduce risk.
Carroll told Reuters earlier this month the company could consider a partner for Minas Rio. Its copper project Quellaveco will be submitted to the board for approval in 2013.
Earnings fell across the board for Anglo in 2012, after what the company said was one of the toughest years both for its own operations and the industry, as weak prices and higher costs took their toll. Iron ore and copper, major contributors to profit, fell by more than 30 percent, hampered by strikes in South Africa and operational troubles at Anglo's copper mines.
"It is about (fixing) platinum, building Minas Rio and getting through the issues in copper. Then they are through it, but that is two years of hard grind - they have a lot of work to do," analyst Des Kilalea at RBC Capital Markets said, adding Anglo's higher dividend had been a key positive surprise.
Operating profit from iron ore fell by 33 percent to $2.95 billion, as lower prices added to losses linked to a strike at unit Kumba Iron Ore's Sishen mine in South Africa. It contributed almost 50 percent of Anglo profit, more than in 2011 as other units like coking coal shrank even further.
Iron ore prices plunged to three-year lows below $87 in September last year, though they have since recovered.
Copper, meanwhile, proved another challenge as hiccups at Anglo's Los Bronces and the Collahuasi mine, in which Anglo and Xstrata own 44 percent, drove up costs. Operating profit there fell 31 percent.
One bright spot on costs was coking coal, where although profits plunged 66 percent Anglo was able to reduce costs in the second half by 20 percent versus the first six months.
South African strikes, particularly in platinum, have been a large part of Anglo's troubles and its Anglo American Platinum unit posted its first annual loss earlier this month.
In an overhaul announced last month, Amplats will mothball two mines, sell another and cut 14,000 jobs.
Diamonds, where Anglo took control of De Beers last year, also provided little cheer, with a 45 percent drop in operating profit on a 100 percent basis, as demand weakened. De Beers was forced to allow its buyers - sightholders - to delay purchases, driving down sales.
