Sydney Morning Herald reports the WA government will reap $1.9 billion more in mining royalties over three years after deals were reached with BHP Billiton and Rio Tinto: Premier Colin Barnett said the royalty rate for fines iron ore - grains smaller than 10 millimetres - would increase from 5.625 per cent of sale revenue to 6.5 per cent from July 1, next year and to 7.5 per cent from July 1, 2013. In return, mining giants BHP Billiton and Rio Tinto would be able to expand their projects in the Pilbara, worth an estimated $30 billion.

Reuters reports Anglo American on Wednesday sold a 24.5% stake in its southern Chilean properties to Japan's Mitsubishi Corp. for $5.39 billion, undermining plans by Chile's state-owned Codelco to exercise an option to buy half of it.

Anglo said the transaction values its Chile properties at $22 billion. Codelco was offering $6 billion for 50%.

Gold for December delivery only briefly broke the psychologically important $1,800/oz level on Wednesday and in after hours trade pulled back sharply to trade at $1,770.50. Gold failed to take advantage of its traditional role as a hedge against inflation and a safe haven in troubled economic times, despite European Union finance ministers failing to make progress on ways to shore up the zone's sagging banks and Italy's deepening credit crisis. Bullion's failure to build on a three-day rally also comes after data out this week showed a quickening in demand from China's consumers who bought a record 56.9 tonnes in September, a sixfold increase year-on-year.
