Bougainville Copper Questions Legality of Panguna Licence Revocation as Shares Tumble 57%

Shares in Bougainville Copper have shed more than half their value in a week after the autonomous government of Bougainville stripped the company of its exploration licence for the giant Panguna copper-gold deposit. The stock closed at €0.13 on Monday and slid a further 5.14% to €0.12 on Tuesday, deepening the seven-day rout to nearly 57%. The 14-day relative strength index has fallen to 21.9, deep in oversold territory, while annualised volatility stands above 184% — evidence of the panic selling that has gripped the stock.
The licence revocation stems from the Bougainville Mining (Amendment) Act 2026, which the regional government passed earlier this year. The Registrar of Tenements notified Bougainville Copper on 16 June that its exploration rights at Panguna had been suspended under the new law. The company’s management now questions whether the legislation was properly enacted and is weighing a legal challenge. Any court filing or settlement with the government could spark the next sharp move in the share price, for better or worse.
In the meantime, the regional government has moved swiftly to install a new operator. It has incorporated Bougainville Minerals Ltd, a consortium owned jointly by the state and local landowners, and granted it a 25-year mining licence. India’s Lloyds Metals and Energy has been named the preferred operating partner, having seen off rival bids from Chinese state-owned enterprises. Lloyds now has an exclusive 90-day window to conduct due diligence and feasibility studies.
Should investors sell immediately? Or is it worth buying Bougainville Copper?
The Panguna deposit is among the world’s largest undeveloped copper and gold resources, estimated to contain 5.3 million tonnes of copper and 19.3 million ounces of gold, with a total in-ground value of roughly US$160 billion. The mine has been idle since 1988, and Bougainville Copper’s entire corporate worth has effectively hinged on regaining access. The licence loss therefore represents an existential blow.
Compounding the company’s predicament is a glaring conflict of interest: the autonomous government owns 72.9% of Bougainville Copper’s shares. It is simultaneously the regulator, the majority shareholder and now the architect of a law that strips the company of its sole asset. President Ishmael Toroama has justified the reorganisation as a way to ensure greater benefits for local landowners, but minority investors see little room for a fair process.
The political backdrop makes a return to the status quo even less likely. Bougainville is pursuing full independence from Papua New Guinea, with a road map that calls for self-government by September 2027 and complete sovereignty between 2030 and 2032. Toroama has demanded absolute control over all natural resources, reinforcing the view that Bougainville Copper’s days as the primary operator are over.
For now, the company must prove in court that the Mining Amendment Act was not lawfully passed. If it fails, it loses its last operational foothold. With the stock already in freefall and no catalyst in sight, the next decisive move belongs to the lawyers.
