Peninsula reported a loss for the year ended 30 June 2026 of US$77.1 million, against US$12.5 million, with a net loss before income tax of US$84.6 million. The result includes a US$50.1 million non-cash impairment, principally of legacy wellfield development Assets for Mine Units 1, 2 and 3 and certain historically capitalised costs. The chair said the impairment reflects a decision to focus technical, operational and Capital resources on Mine Unit 4 and future mine development, and does not alter the board's view of the long-term potential of the Lance Project.

Operations at Lance

Peninsula completed capital works for the Central Processing Plant expansion, advanced Mine Unit 4 and began operations in the new low-pH mine unit. Acidification of Header House 14 began in late December 2025. The chair reported that uranium head grades from Mine Unit 4 have been higher than prior alkaline operations, but that combining sulphuric acid and hydrogen peroxide appeared to cause gas buildup and solids precipitation, reducing flowrates and increasing maintenance needs.

The site team modified acidification procedures and maintenance practices for later header houses, and the chair said results from such changes are measured in months. This was the first use of a low-pH leach basis at a US uranium mine in several decades.

In an announcement on 25 September 2026, Peninsula reported that the Lance Mineral Resource increased by 1.0 Mlbs to 59 Mlbs U3O8.

The report also records that Peninsula adopted learnings from acidifying Header Houses 14 and 16, and that site procedures and wellfield maintenance practices were modified for subsequent header houses. The chair described growth in nuclear power as supporting uranium Demand and thanked shareholders and employees, noting that restarting projects is not easy.
