Bougainville Copper’s Panguna rights remain suspended as cash outflows rise

Panguna licence uncertainty overshadows wider half-year loss

Bougainville Copper Limited (ASX:BOC) has reported a K13.4 million net loss for the six months ended 30 June 2026, almost double the K7.4 million loss recorded in the corresponding period. The result was equivalent to an AUD4.4 million loss, compared with AUD2.8 million a year earlier, using the average exchange rates disclosed by the company.

The more consequential issue sits beyond the income statement. Bougainville Copper says its rights under Exploration Licence EL01 have been suspended and subordinated to Large-Scale Mining Lease No. 01, granted to Bougainville Minerals Limited for 25 years over the same area. The company’s independent board committee delivered its findings in September, but Bougainville Copper is still obtaining legal advice before deciding what action to take.

The licence dispute was previously reported when the 25-year mining lease grant prompted the company to establish an independent committee. The latest filing provides no resolution to that dispute, leaving the future legal and strategic position of the Panguna project unsettled.

Investment sales are funding a cash-burning structure

Bougainville Copper generated K1.552 million in income, mostly dividends, broadly in line with the prior period. Against that, general and administration expenses rose to K14.873 million from K8.645 million, while total operating expenses reached K14.950 million. A one-off AUD1.0 million, or PGK3.034 million, contract termination fee related to the abandoned process to identify a Panguna development partner was a significant contributor.

Operating cash flow was negative K12.263 million, compared with negative K6.886 million in the first half of 2025. The company received K11.997 million from selling investments during the period and said further disposals would be made in the second half to fund ongoing operations. Cash stood at K1.554 million at 30 June, while the group had no borrowings.

The partner dispute had already surfaced when the board selected CMOC Group as its preferred mining partner, while the Autonomous Bougainville Government favoured Lloyds Metal and Energy. The company subsequently terminated its engagement with Grant Samuel Services and paid the termination fee. That earlier Panguna partner dispute now sits alongside the licence issue as a second unresolved obstacle to any mine-development pathway described in the filing.

Qualified review flags valuation and asset uncertainty

Net assets fell to K63.436 million from K79.459 million at the end of June 2025. The company’s holdings include K67.23 million in ASX-listed equities, alongside a K1.1 million holding in the unlisted Pacific Balanced Fund through the Bougainville Copper Foundation. Because current financial information and pricing data were unavailable, management could not determine whether the fund’s carrying value was fairly stated.

New auditor Kuna Taberia Kiruwi Accountants & Advisors issued a qualified conclusion on the interim financial information over that K1.1 million valuation. The review also included an emphasis of matter on the significant uncertainty surrounding the future of the Panguna mine and related assets, particularly the company’s rights to those assets. The filing says those mine assets had already been fully depreciated or impaired in previous financial years.

Ownership and legal claims add to the list of open issues

The Autonomous Bougainville Government officially took control of a combined 72.9% stake in Bougainville Copper in January after the PNG National Government transferred its 36.45% holding. The board also changed during the period, with Kearnneth Nanei becoming chairman and Sir Melchior Togolo moving from chairman to the board and then acting as CEO.

There was no dividend for the half year. Remediation work around legacy Panguna infrastructure continues with the ABG and Rio Tinto, while an appeal remains pending after PNG’s National Court dismissed a representative action against Bougainville Copper and Rio Tinto in September 2025. The immediate financial question is how long investment disposals can support the company while its principal mining rights remain under challenge and its operating cash flow stays negative.
