Besieged miner Anglo American has confirmed itself as the likely biggest seller of assets in the global mining sector this year, upgrading its target for disposals to $US6 billion this year. 
The loss-making miner sold $US2.1 billion of assets in 2015, and wants to offload a further $US3 billion or $US4 billion of assets in 2016 to reach the target.
Among the assets Anglo has been trying to sell are a cluster of marginal Australian coal mines, and the company confirmed that its best Australian coal assets, Grosvenor and Moranbah, were now on the market as well.
"We have deemed all of the coal assets in australia as non-core," said Anglo chief executive Mark Cutifani???.
Anglo said the sale processes were underway and an update could come within weeks.
"We a have given ourselves plenty of room to negotiate for value," said Mr Cutifani.
"We don't need to sell any of those assets under value."
But unfortunately for acquisitive miners like Rio Tinto and BHP Billiton, Anglo says it wants to keep its best copper assets as part of its leaner, more streamlined future.
In a major strategy update on Tuesday, Anglo chief executive Mark Cutifani said he wanted to business to focus on just 16 assets across three product groups; diamonds, platinum group metals and copper.
BHP and Rio are both keen to bolster their copper divisions, but in a video published on the Anglo website, Mr Cutifani indicated that the company wanted to retain its stake in the Los Bronces and Collahuasi??? mines in Chile.
Anglo, which posted a $US5.6 billion loss, will look to sell its iron ore, coal, phosphates, nickel, manganese and niobium assets.
Anglo shares the Cerrejon coal mine in Colombia with BHP and Glencore, and Mr Cutifani hinted the asset could be bought by one of those partners.
South32 looms as the natural owner for Anglo's manganese assets, given it owns 60 per cent of the assets Anglo has exposure to, but with manganese prices severely depressed, it is unclear whether South32 will be interested in Anglo's stake.
"South32 is our partner in the assets, so yes we have had a conversation and they are aware of our intentions," said Mr Cutifani.
The two companies have reduced manganese output in a bid to ride out the weak prices.
Anglo will complete construction of its Minas Rio iron ore project in Brazil but has said it is non-core. The Kumba iron ore business in South Africa will be divested, with a spin out possible.
Tuesday's comments come after Anglo flagged it would cut 85,000 jobs back in   December.
