Boss Energy Limited (ASX:BOE) operates the Honeymoon uranium operation in South Australia and holds a 30% interest in the Alta Mesa uranium operation in Texas. On 11 November 2026, its ASX:BOE shares advanced 1.25% to AUD 1.62 during the trading session. The latest 2026 reports place emphasis on fy26 results and the revised mine plan, alongside operating, funding and approval questions relevant to the company’s assets.

Uranium Production Across Two Operations

For Boss Energy Limited (ASX:BOE), the Honeymoon operation uses in-situ recovery, circulating solution through underground mineralisation and recovering uranium at surface. This differs from conventional open-pit mining, but requires careful management of groundwater, wellfield hydraulics and processing systems. Boss holds all of Honeymoon and a minority interest in Alta Mesa in South Texas. The two sites have different ownership and operating arrangements, so production reported for the Australian operation should not be treated as the group’s entire attributable uranium production. The company’s Economics also depend on realised uranium sales prices and contracted deliveries.

FY26 Results and the Revised Mine Plan

For Boss Energy Limited (ASX:BOE), honeymoon produced 1.407 million pounds of U3O8 in FY26, an increase of 61% from the preceding year. Reported FY26 C1 costs were AUD 39 per pound and all-in sustaining costs were AUD 61 per pound, within revised guidance. By 30 June 2026, six producing wellfields and five NIMCIX processing columns were online. In August 2026, Boss released a new feasibility study reflecting operating observations and a wider-spaced wellfield configuration. The revised study constitutes a forward-looking mine plan, not evidence that the proposed efficiencies have already been delivered.

September 2026 Development Direction

At its September 2026 market day, Boss described a potential hub-and-spoke configuration involving Honeymoon and the Gould’s Dam and Jason’s deposits. The latter deposits were the subject of new resource estimates in March 2026: 33.1 million pounds and 12.0 million pounds of contained U3O8 respectively. Those resources are not interchangeable with mined output or saleable inventories. A development decision would require further technical, funding and regulatory work. The company’s Australian and United States activities also create different operational and administrative exposures.

Operating Risks and Upcoming Milestones

The new Honeymoon plan depends on wellfield productivity, recovery performance, cost discipline and the commissioning or sequencing of additional infrastructure. Deviations in uranium grade, solution chemistry or operating availability could affect the relationship between processed volumes and finished product. Boss reported AUD 207.3 million in cash and liquid assets at 30 June 2026, but Capital spending and operating costs will continue to shape its funding position. Future quarterly disclosures can be used to assess output against the revised plan, rather than assuming feasibility forecasts represent achieved performance.

Key Insights

Boss Energy Limited (ASX:BOE) — Boss enters FY27 with a producing Australian uranium asset, US exposure and a revised development framework. Attention turns to the execution of the Honeymoon wellfield plan, quarterly uranium output, costs and the treatment of satellite deposits.
