I do wonder how the debt component of any mine development package will get funded. You just need to look at the difficulty that GPR in PNG are having in securing their debt component. Now they also have the deep sea tailing problem that switches off a lot of mainstream banks but their political situation is not as volatile as Myanmar
I do suspect it will require a run up on silver to more historical norms viz a viz the gold price to unlock this one. Eventually it will become so profitable that they can afford to pay some crazy coupon to get the debt done. As such I will sit on the sidelines
