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%.

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.

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.

Iron ore prices have turned around after crashing 30% in October, but longer term the outlook is not rosy for smaller players thanks in large part to the aggressive go-to-market strategy of the big three.

Consumers made the most of the dip in the price of bullion and mainland China's gold purchases via Hong Kong hit a record 56.9 tonnes in September, a sixfold increase year-on-year and up 30% from August, according to figures released by the Hong Kong government and reported by the FT. Quarterly data from the Hong Kong census and statistics office showed the Middle Kingdom imported about 140 tonnes of gold via Hong Kong in the three months from July to September ahead of the festival season, more than the roughly 120 tonnes for the whole of 2010. Over the last decade China's share of total global demand for bullion has climbed from 6% to 18%.

Bloomberg reports Rio de Janeiro-based Vale SA, the world’s largest iron-ore producer, said prices for the raw material have stabilized and are recovering from “rock bottom” levels as a result of lower-than-expected production and strong demand from China, India and South America. Iron ore for immediate delivery has gained 8% to $126.30 a tonne since reaching its lowest level in almost two years at the end of October. During the month iron ore prices crashed almost 30% forcing the big three – BHP, Vale and Rio Tinto control nearly 70% of the 1 billion tonne annual iron ore seaborne trade – to renegotiate quarterly contracts with Chinese buyers to bring values more in line with the spot price.

Silvercorp Metals on Tuesday reported revenue of $62.1 million for its second quarter, up 71% from the same period last year. Cash flow from operations hit a record $35.2 million, or $0.20 per share, up 140% from 2011 while net income of $18.5 million, or $0.11 per share, showed a 49% increase. Silver production of 1.4 million ounces rose a disappointing 4% but gold production shot up to 2,516 ounces. Silvercorp said it continues to maintain its low cost producer status with a cash production cost per ounce of silver of negative $4.55.

Platts reports that the global operations headquarters of US giant Peabody Energy will be relocated to Brisbane following the acquisition of Australia's Macarthur. Peabody raised $3.1 billion with the sale of senior notes on Monday and now owns 77.6% of Macarthur after ArcelorMittal pulled out of its joint $5 billion bid for the coking coal producer, just days after the target's top shareholder accepted the offer. Peabody is the world's largest private-sector coal company with 2010 sales of 246 million tons and nearly $7 billion in revenues.
