What price U price wil get GLE moving again?

Anybody have any thoughts on what U price would get GLE moving again? I would think a time factor would also be involved, in that the price rise would have to be seen as sustained, not a dead cat bounce. Junior miners have suggested $80 a pound to get them moving, larger players seem to be moving already, with a murmur about Olympic Dam possibly proceeding with expansion plans previously shelved. So any guesses on the sustained price that may spark GLE into action?
Sentiment is hold but would love, like everybody else, a crystal ball running into the AGM.
Good luck, hope the long termers can recover something, I think you deserve it.
