Miners to spend $21 billion on exploration by 2025

The human rights organization – co-nominated for the 2003 Nobel Peace Prize for its work on conflict diamonds – said the decision to allow diamonds from Zimbabwe's rich Marange fields means the money that flows from there ends up in the pockets of the Robert Mugabe-aligned military's top brass who could use it to organize support to intimidate the opposition in the run-up to elections. Hundreds were killed and thousands of local miners were driven off claims when the Zimbabwe army seized control of the Marange area in 2008.

Silver was up marginally to $32.86 from yesterday's $31.92, while benchmark copper was up more than 5% to a two-week high of $7,885/tonne. Zinc, lead, aluminum and nickel were also up from Tuesday.

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.

One of the more unique lots at Christie's Magnificent Jewels auction on November 29 in Hong Kong is likely to be a set of poker chips made by the Swedish artist and jeweller Kristian Ståhl. The 120 chips are made of 18K white gold and are set with a total of 5,160 calibrated top-quality diamonds, rubies and sapphires. But what makes the set truly unique is that each chip was sliced from the 1 million year old Muonionalusta meteorite that contains iron, nickel and rare earths. The set is estimated at $100,000 – $150,000 and Stahl said he was inspired to create it after his Siberian mammoth ivory dice sold well at auction last year.
