How about $1.20
Reason if we go back three months from today ( to allow for the 3 month slide in production schedule) the SP was around 60c. So it is feasible for the Sp to go back to this amount. But ( as long as no further delays are expected) the SP will start to climb again in the same manner as before, ie as production draws nearer.
From this reasoning I think $1.20 is extremely possible
