I have considered this and take a little comfort from the fact that they have 3 tries to get it right, coupled with their all-round experience. No risk, no reward though.
Also consider the possibility that a good result may not shift the price as much you think as future production will still need capitalising etc. Always good to be ready for all outcomes.
As for selling down, sell until you are comfortable with amount you have at risk I suppose!
