Boss Energy Ltd (ASX: BOE) has reported a strong September quarter, with record drummed production of 385,910 lbs of U3O8 at its Honeymoon Uranium Project in South Australia, up 11% from the previous quarter. The company achieved an average realised price of $114.3/lb (US$74.7/lb) and C1 cash costs of $34/lb (US$22/lb), below the FY2026 guidance range of $41-45/lb (US$27-29/lb). All-in sustaining costs (AISC) were $50/lb (US$33/lb), also below the guidance range of $64-70/lb (US$41-45/lb). The company's balance sheet remains robust, with $212.4 million in cash and liquid assets and zero debt. Boss also made significant progress on construction activities, with the NIMCIX column 4 commissioning commenced and columns 5 and 6 continuing to be progressed. Wellfield 4 was brought online, and the wellhouse for wellfield 5 was delivered to site. The company has also commenced a program of work to accelerate the permitting of satellite deposits, including Brooks Dam North, Jason's Deposit, and Gould's Dam. The Honeymoon Review, which will compare the continuity of mineralisation and leachability results with the assumptions in the Enhanced Feasibility Study, is a priority and on track for completion in the December quarter. At the Alta Mesa Uranium Operation in South Texas, where Boss holds a 30% interest, drummed production was 206,231 lbs of U3O8 (100% basis), with Boss receiving 45,102 lbs reflecting its pro rata share. The company also acquired the highly prospective Alta Mesa East Property adjacent to the existing operations.

Boss Energy is on track to meet its FY2026 production guidance of 1.6 million lbs of U3O8, with C1 cash costs of $41-45/lb (US$27-29/lb) and AISC of $64-70/lb (US$41-45/lb).

The company is focused on completing the Honeymoon Review, advancing the permitting of satellite deposits, and continuing to optimize costs and production at both the Honeymoon and Alta Mesa operations.
