Bougainville Copper Shares Slide Again as Panguna Control Slips Further Away

Bougainville Copper loses Panguna control to state-owned BML and Lloyds, triggering a 31% monthly share crash amid new mining law.

Investors in Bougainville Copper are facing another bruising session, with the stock shedding 10 percent to trade at €0.1020 on Thursday. The latest decline extends a brutal stretch that has now wiped roughly 31 percent off the share price over the past month, as the company's grip on one of the world's most coveted copper and gold deposits continues to loosen.

The market's pessimism is rooted in a fundamental shift: the Autonomous Bougainville Government (ABG) has moved decisively to hand control of the Panguna mine's future to a new alliance, leaving the former license holder watching from the sidelines.

A New License Structure Reshapes the Playing Field

The regulatory ground beneath Bougainville Copper has shifted dramatically in recent weeks. On August 12, the company disclosed that its longstanding exploration license, EL01, covering the Panguna deposit had been suspended. The move stems from the "Bougainville Mining (Amendment) Act 2026," a sweeping piece of legislation that subordinates the company's previous rights to a newly issued 25-year Large-Scale Mining Lease, now held by the state-owned Bougainville Minerals Ltd. (BML).

That new license structure was formalized when President Ishmael Toroama presented BML and its Indian partner, Lloyds Metals & Energy, with the official certificate to commence feasibility studies. The certification effectively neutralizes Bougainville Copper's historical claim to the site, which has remained shuttered since 1989 when civil conflict forced its closure.

Lloyds Emerges as the Government's Chosen Partner

The selection of Lloyds Metals & Energy as the preferred development partner marks a decisive break with the past. Reports indicate that on August 7, the company won the mandate to carry out preparatory work and feasibility activities, beating out a field of international contenders — including the CMOC Group, whose proposed partnership was rejected by the government back in February.

Lloyds has moved quickly to cement its position, establishing a Papua New Guinea subsidiary in May and now preparing to undertake a full resource reassessment alongside detailed mine development planning. The government's backing of the Indian conglomerate signals that the Toroama administration is looking beyond the old guard to forge new international alliances.

Ownership Shift Adds Another Layer of Complexity

The license restructuring has been accompanied by a fundamental change in corporate ownership. On June 26, the ABG assumed majority control of Bougainville Copper following the formal transfer of Papua New Guinea's 36.45 percent stake — handed over by Prime Minister James Marape to President Toroama — which lifted the ABG's holding to 72.9 percent.

The ownership transition has been mirrored by a redistribution of revenue authority. Through the Joint Supervisory Body, Marape and Toroama have agreed to a complete transfer of fiscal responsibilities, with mining, forestry, and fisheries revenues slated to move from the central government to the autonomous region by December 31, 2026. This economic decoupling strengthens the hand of local state entities at the expense of former license holders.

Political Calendar Looms Large

The immediate focus now shifts to Port Moresby, where the national parliament is scheduled to debate the ratification of the 2019 independence referendum. The secondary source indicates this pivotal discussion is set for August 27, while the primary article points to a vote on August 30 concerning the broader regulatory framework. Either way, the outcome will shape not only Bougainville's legal status but also the conditions under which international partners like Lloyds can secure long-term investment certainty.

For Bougainville Copper, the near-term outlook offers little comfort. With Sir Melchior Togolo having taken the helm as chief executive in May, the company must now navigate a landscape where its role in the newly constituted license structure remains deeply uncertain. The parliamentary deliberations will likely prove decisive in determining whether the company retains any meaningful function in Panguna's future — or whether it is relegated permanently to the role of observer as BML consolidates its control over the island's key resources.
