SYDNEY, Nov 28 (Reuters) - Bougainville Vice President Raymond Masono said he will revive a plan to overhaul the region's mining laws after its ongoing independence referendum, which could strip the former operator of the Panguna gold and copper project of its interests.
The proposed changes, which have been criticised by Panguna landowners, would also erase an interest in the project held by the Papua New Guinea government, potentially complicating negotiations between the two governments after the referendum.
Under the proposed mining law amendments, Bougainville would take a 60% share in all projects and retain all mining licences, leaving a 40% share that investors can bid for.
"Panguna is the most likely project that can bankroll Bougainville's independence from Papua New Guinea," Masono, who is also Bougainville's mining minister, told Reuters by telephone from the town of Buka.
"They don't own the licence and the mine, we own it - they come on our terms."
He said companies like former Panguna operator Bougainville Copper Ltd (BCL), which counts the PNG government as a major shareholder and claims exploration rights at Panguna, would not get "special treatment".
"They can only come in through the new framework. If they have money they can invest as will other investors."
BCL declined to comment. The PNG government did not immediately respond to a request for comment.
Masono said he would push for the plan to go through Bougainville's parliament in December, after it was shelved in the lead-up to the referendum amid a backlash from some landowners and government members.
