Reports are that the good folk in Bougainville have been negotiating to repoen the mine., that would help pay for the place
With the right deal for them and the prospective miners it could be very lucrative for both.
Billions got ripped out of the place by others and environmental damage still remains
PNG may want to get shot of the place now that the rivers of kina stopped during the civil war and presumably there is some prop up from PNG now.
If they become a free standing country, I.d posit they would keep the NZ based reg suite as in PNG.
Best to leave CAsA well out of it, and make life easier for all.
Good on .em Nothing ventured .nothing gained.
If it all falls over Im sure Chine would be in there to help quick as a flash
