In a US class action launched under the Alien Tort Statute, Bougainvillean landowners maintain that Rio Tinto’s subsidiary, Bougainville Copper Limited (BCL), supplied the military with trucks, fuel, accommodation, storage facilities, mess halls, communications equipment and secretarial services.

These allegations were featured in a hard-hitting Dateline report aired on SBS TV in 2011.

In response, company executives adamantly denied complicity. They claimed Rio Tinto’s equipment was commandeered by the defence force after the mine had been abandoned.

BCL director Sir Rabbie Namaliu told The Australian on 16 July 2011: “To suggest that Rio did it deliberately is factually wrong. When I heard about those claims, I thought the whole thing was rather unfair.”

Namaliu was prime minister of PNG from 1988 to 1992. Amnesty International said PNG forces stationed in Bougainville during this period took part in extra-judicial killings, village burnings and the rape of women.

Namaliu is hardly an uncompromised source.

There are other problems with his account. For example, I interviewed eight senior managers who worked for BCL during 1987-1992. They were confident the company did supply the defence force with the aforementioned equipment.

One manager told me: “We did everything they [PNG security forces] asked of us to make their life more comfortable, and better able to manage through, with transport, communications, provisions, whatever, fuel.

“You know, we gave them everything, because as a far as we saw it we were hoping that they were going to solve the situation, so we could start operating again. So we supported them every way we could.”

Perhaps BCL was unaware of the ends to which this logistic support would be applied? Well, its executives seem fairly cogent on this front too.

One manager recalled: “These guys [PNG security forces] were ignorant thugs with guns. Frightened ignorant thugs with guns. Frightened, ignorant thugs with guns a long way from home.”

Another executive remembered surveying the destruction inflicted upon local villages by government forces during April 1989: “Forty, 50 villages, and the crops [were destroyed]. The villages were varying from five or six houses to 20 or 30 houses.”

Naturally, Rio Tinto wants to take advantage of skyrocketing copper and gold prices by dusting off its old South Pacific jewel. I am sure they are attracting a degree of community support from war-weary Bougainvilleans looking to rebuild their shattered island.

That said, communities on Bougainville have yet to be fully briefed on Rio Tinto’s role in defence force operations during the bloody years of 1988-1990. So it would be difficult to argue that this support is based upon informed consent.

Until Rio Tinto commits to full disclosure, any attempt to reopen the Bougainville mine will be another corporate blight on the deeply scarred people of this Melanesian island.
