Output of copper cathodes and copper concentrates are beginning to be affected by a work stoppage that began Monday at the giant Collahuasi copper mine in Chile. Reuters reports that the mine, jointly owned by Xstrata and Anglo American, has implemented a contingency plan to deal with the labour action, which about 10% of workers are participating in: Some workers in Collahuasi, which produces about 3 percent of the world's copper, downed tools on Monday over fears of coming layoffs. The company later on Monday announced it had laid off a "limited" number of workers in response to a partial one-day strike in October, a move that could stoke tensions between management and the union.

Saskatchewan's first potash mine in 40 years was approved today in the small city of Moose Jaw.

"The Legacy Project is a significant step towards the expansion of our potash capacities and enables us to participate in the growth of the global potash market.

BHP Billiton said today it is reviewing its diamond business, which includes two large diamond mines in northern Canada, for a potential sale of all or parts of the business. The world's largest mining company said the review, expected to be completed by the end of January, will "examine whether a continued presence in the diamonds industry is consistent with BHP Billiton’s strategy." BHP owns 80% of the Ekati diamond mine in Canada's Northwest Territories. The other 20% is owned by geologists Chuck Fipke and Stewart Blusson (each has a 10% stake), who discovered the kimberlite pipes north of Lac de Gras in 1991. BHP also owns 51% of the Chidliak diamond exploration property on Baffin Island, with the other 49% owned by Peregrine Diamonds which has been exploring the 860,000-hectare property since 2006. Chidliak also contains copper, platinum group metals and lead-zinc.

Geekosystems reports on a new use for diamonds, providing truly unknowable random numbers that could serve the basis for secure communication. Random numbers are at the heart of modern communication, used for electronic commerce, wireless networks and bank transactions. The basis of secure communication is generating a random number, known as the key, that is shared by the recipient and the sender that is then used to scramble and unscramble the message that is sent between the two parties.

Australian landowner Ian Moore has taken to court his battle against coal company NuCoal, which wants access to drill three boreholes on his property north of Sydney for its proposed Doyle’s Creek mine. Moore says he opposed the operations because of the potential damage it could cause to underground water supplies and because he is legally blind and relies on a visual memory of his property to farm, which the drilling operations and bore holes could hinder. The beef farmer has been backed up by locals, who fear their property could be next.

China's Ministry of Industry and Information Technology (MIIT) is drafting new standards for the gold industry which will raise the entry barriers and it will force companies with daily gold processing capacity of less than 50 tons to shut down. Citing unidentified sources who attended a national gold mining conference, the industry ministry is drawing up a blueprint to better regulate gold miners, such as shutting mines with a daily gold processing capacity of below 100 tonnes and halting approvals for small ore processing companies. China, the world's largest bullion producer, currently has no limits on gold production and production is determined by the gold producers.
