Smith said the aluminium price has been increasing (it traded at $US2030 per tonne during the day) and there was renewed hope that the Tiwai Point smelter would remain open.
"The reason Rio Tinto gave for pulling the plug was that the smelter was not profitable. There is now more of a chance of becoming a profitable enterprise and they may re-look at their decision," he said.

The consortium, with NZOG having 15 per cent, drilled to the target depth of 5275m, intersected the remaining sands and found no significant hydrocarbon shows. Smith said he was once told: "The best well is the one that is never drilled. It's disappointing – the oil price is heading back to $US50 per barrel."
