Sov risk not a biggy? One of the poorest nations in the Western Hemisphere...
It's the main factor holding the SP back and likely to be the only factor that can stop this project moving forward once DD is complete imo.
New president and Gov will hopefully come through with the goods, but won't be an easy ride
Newmont didn't have much luck and neither did Majescor, which are probably a more realistic comparison at this point being they are also a junior.

Makes it a biggy imo, but at these levels, the potential risk/reward ratio is huge. Comes with it's fair share of risk though.
Will all come down to the new Government.
