In June 2019, Kuhns flew several landowners to the U.S. to meet potential investors, including representatives from Barrick Gold Corp. At the Harvard Club in Midtown Manhattan, where stuffed moose, bison and even an elephant head adorn the rooms, the landowners heard Kuhns deliver a PowerPoint presentation introducing potential investors to Bougainville.

Barrick declined to comment.

“Panguna mine can be rejuvenated and can be resuscitated for a couple of billion dollars,” said Kuhns in a follow up phone interview. “It’s going to take a major to do that.”

Among those also interested in Panguna is Jeff McGlinn, who made his fortune in mining and construction services through Western Australia-based NRW Holdings Ltd., which he co-founded. McGlinn, who resigned from NRW in 2010, is part of the glamorous world of Arabian horse breeding, mixing with models and celebrities at parties on the French Riviera and promoting luxury brands. He once gave an Arabian colt to Italian opera singer Andrea Bocelli.

McGlinn’s roots in mining give him valuable experience for Panguna -- one of NRW’s businesses was constructing dams that hold mining waste. He’s also linked to a recent effort by the island’s government to kick start development, when it created Bougainville Advance Mining. The government’s Executive Council proposed last year an amendment to the 2015 mining act that would give all available mining rights to the new company, in which McGlinn’s Caballus Mining would hold a stake.

That amendment drew criticism from landowners, as well as Bougainville Copper, the former mine operator, which says the proposal undermines its rights to mine Panguna. The bill was later shelved. A representative of Caballus said McGlinn was unavailable to comment.

Another interested party is Richard Hains, son of the Australian billionaire David Hains. Richard, famous for keeping wallabies on his Gloucestershire estate, has helped develop mines in some of the world’s most difficult places. He’s the largest shareholder of RTG Mining Inc., whose management team has financed, built and operated mines across Africa and Asia, including the Boroo gold mine in Mongolia.

“Some of the best opportunities in the mining business in the 21st century are now in the more difficult commercial environments,” Hains said in a phone interview.

RTG believes it can restart production at Panguna through a staged process in as little as 18 months for about $800 million.

“It’s far smarter to start with a smaller footprint,” said RTG Chairman Michael Carrick. “Then in consultation with the community, we can turn up the mine’s operation.”
