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."

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.
