Rio Tinto Group and Anglo American Plc (AAL), which together own about three-quarters of Palabora Mining Co., said they plan to sell their entire holdings in the South African miner as it no longer fits their investment objectives. Palabora’s main asset, a mine that produces copper and magnetite, “is no longer of a sufficient scale” for either Rio or Anglo, and a sale process for their stakes has started, the companies said today. Rio holds about 58 percent of Palabora and London-based Anglo almost 17 percent. Their combined holding is valued at about $700 million based on the closing price of Palabora stock in Johannesburg trading today. Image of copper spools at Palabora mine, courtesy of Rio Tinto

Beating already rosy expectations new Australian Bureau of Statistics figures show mining companies intend to invest $82.1 billion this financial year on new and expansion projects, representing 55% of total capital expenditure in the country's economy. The spending spree by the resources sector – mostly in Western Australia and Queensland – represents a whopping 70% increase over last year. Mining firms spent 14.4% more last quarter, led by a 22% jump in plant and machinery purchases, and projections show further increases in the future.

The Columbus Republic reports opponents of a planned nickel and copper mine in Michigan's Upper Peninsula are asking a judge to put a state-issued permit for the project on hold ahead of initial blasting expected later this month. Four organizations have asked a judge to issue a stay while considering an appeal of the Department of Environmental Quality's 2007 decision to grant Kennecott Eagle Minerals, a subsidiary of Rio Tinto, a permit. Kennecott Eagle is targeting an underground ore deposit that would be the only US mine where nickel is the primary mineral generated instead of a byproduct. The mine could yield up to 300 million pounds of nickel and about 200 million pounds of copper.
