RE:RE:your JV is probably dead.Don't underestimate the resolve of American government to address irritants in Central and South America. This is their backyard.
I would tend to agree with you if Rusoro had no linkage to any American entity. But is not the law firm is US-based? What about others that stand to profit? There may be other institutional linkages, etc.
The share price runup was based on a successful conclusion to the agreement reached with VZ. If there are any American entities, persons corporations or otherwise that stand to profit from the agreement, their profits may be seized by the US government and these entities may be subject to additional prosecutions.
So if there is any risk the agreement is in jeopardy as a consequence of Trump's sanctions, the support for the current share price must also be in jeopardy. Yes, a white knight Chinese or Russian corporation could buy them out and eliminate the possibility of the aforementioned outcome as you and other have suggested. However, this would likely mean Rusoro's bargaining position is slightly weaker and the buyout will be lower than the expected payout. If it did resolve in short order, it could be a boon for the shareholder since they would be insulated from any VZ default risk. But this is a theoretical based on hope. A Chinese company could have bought you out already, why haven't they?
