RE:3.5 years from re-start to full production....Ultimately it is a US based asset in an increasingly more deglobalized world. Copper supply globally is on huge stress from multi decade degrading mines that it is hard to see massive price declines. Fiscal stimulus is also a certainty in near future especially if the unemployment persists. If you look at insider option structure, I would say that the goal is to realize the value in a shorter time frame than 4 years for sure. Take over highly likely.
