RE:Winds of ChangeSherritt is out of money. Now.
The American election cycle is the last place for changing America's stance towards Cuba I'd suggest. And, that won't wrap up until November. After that there's going to be the storm and fury over whomever lost the race. I can't see Trump suddenly going quietly into the night, so that means there's bigger fish to fry in the many months thereafter.
If there even is nickel being mined at Moa soon, I would frankly be surprised.
