I agree @rkb the main game is with the proven reserves. But these were once fringe opportunities that now appear real.

Being a long time holder of OZ Minerals I was interested to see COB's agreement with OZ to progress recoverability of cobalt and gold from the similar cobalt-pyrite minerals to those at BHCP. Carrapateena copper mine minerology is no Robinson Crusoe in the copper mining game.

Even with success at the Millennium Project at GEMC trialling similar technology COB were careful to restate that their focus remains on the core BHCP
