The Alberta oilsands has a new kid in town. Calgary Herald reports that Grizzly Oil Sands, a privately-owned company, has been approved for an 11,300 barrel-per-day, in-situ oilsands project southwest of Fort McMurrray: Cabinet approval for the project was given this week after approval was sought last year but chief executive John Pearce said the process of engineering and ordering equipment is already well underway. The company expects first production by early 2013, and to grow production at its other property to 60,000 bopd by 2020 reports The Herald.

Mining Review reports the decision last week to allow Zimbabwe to resume diamond exports from the controversial Chiadzwa and Marange alluvial fields is being questioned, after the country's mines minister admitted on Thursday that smuggling was still rife. The comments are in stark contrast to his previous insistence that the country's diamond industry was meeting international trade standards. Zimbabwe is set to earn over $2 billion per year from exports with current diamond output estimated to be in excess of 25% of world production. Rough diamond prices have dropped by more than 10% over the last two months and is set to fall further as the first Marange diamonds come onto the market by the end of this month.

Reuters reports the Chairman of Chile's Codelco vowed on Thursday to go ahead with buying a 49% stake in Anglo American's southern Chilean properties. The state copper giant said that it would take all steps to ensure its option is respected and that it did not mind if Anglo cedes a part of its own stake to others. Anglo American on Wednesday sold a 24.5% stake in the properties that includes the newly expanded $2.8 billion Los Bronces mine 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. Chile decided at the end of October to exercise the 33-year old option that has lapsed before, blindsiding Anglo. Anglo said the transaction values its Chile properties at $22 billion. Codelco was offering $6 billion for 50%.

Minera Andes, an exploration company looking for gold, silver and copper in Argentina, announced net income of $6.8 million in Q3 compared to a $5.6 million loss during the same period a year ago. The company also reported that it has US$45 million in cash as at September 30, 2011 with no debt. The company, which has a 49% ownership interest of the San José Mine, attributed the gain to high gold and silver prices.

Mega-miners BHP Billiton and Rio Tinto on Thursday learned the price of their planned expansions in the Australian Pilbara: increased iron ore royalties to the West Australian government. 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. Chile decided at the end of October, barely a week after Anglo American announced that the $2.8 billion they splashed on expanding their flagship Los Bronces mine will start to bear fruit before year end, to exercise the 33-year old option that has lapsed before, blindsiding Anglo. Anglo said the transaction values its Chile properties at $22 billion. Codelco was offering $6 billion for 50%.

Despite a pre-feasibility study packed with good news and an ever-louder drumbeat suggesting an imminent takeout, Western Potash sank 6.67% on Wednesday, a day the broader market managed to keep losses to less than 3%. Western Potash said on Monday it is upping the projected capacity of the Milestone project by 12% to 2.8 million tonnes per year and surprised by lowering its capex and opex cost projections. Scotia Capital commented that state-owned entities from Brazil, India and China could be interested in Western Potash to secure supply outside of Canpotex and Russian producers which together control around 57% of global supply.
