I would think that higher recoveries will be beneficial but I don't see them as game changers.
Despite the enormous potential of this stock, we are trading where we are because of what has already been mentioned PLUS Teck has other copper plays in its Satellite portfolio, which they are moving on. They haven't moved on us because we haven't pushed and, as has been pointed out here many times over the years by golfyeti, they are "starving" us into submission.
Finally selling an asset (VD, FFS!) would demonstrate to investors our ability to deliver, would bring attention, raise the SP, and fill the coffers to rapidly advance our other assets for potential sales, which will take some time to achieve, even with $$.
It would also demonstrate to Teck that we aren't at their mercy.
