"BHP Billiton is sitting on more than $1 trillion worth of copper, uranium and gold at its gigantic Olympic Dam deposit in South Australia, after yesterday reporting a near doubling in ore resources.

The increase is set to support mining at Olympic Dam and the tiny town of Roxby Downs, 560km north of Adelaide, for 100 years or more. It is likely to encourage incoming BHP boss Marius Kloppers to perhaps double the size of a planned expansion. "

Olympic Dam is the closest electricity market for both GRK and GDY.
