ASX 300 uranium stock ramps up production
Boss Energy shares are outperforming today with the miner reporting producing 362,000 pounds of uranium over the quarter. That's up 79% quarter on quarter, with Boss noting that Q3 production was impacted by heavy rains.
The ASX 300 uranium stock received an average price of $107 per pound over the quarter.
And the big uplift in Q4 saw Boss Energy meet its revised FY 2026 production guidance, with the miner producing 1.41 million pounds of uranium over the full year.
On the cost front, FY 2026 all-in sustaining costs (AISC) came in at $61 per pound, also within the company's guidance range.
Turning to the balance sheet, Boss Energy reported end of year cash and liquid assets of $207.3 million, up 7% year on year.
The quarter also saw the miner complete the delineation drilling program across all of its South Australian Honeymoon Uranium Project, which management said will serve to "underpin a more robust mineral resource estimate" (MRE).
The company is aiming to deliver Honeymoon's New Feasibility Study by the end of August. Boss will provide FY 2027 guidance when it delivers that New Feasibility Study.
What did Boss Energy management say?
Commenting on the results helping lift the ASX 300 uranium stock today, Boss Energy CEO and managing director Matthew Dusci said, "The June quarter represents a positive finish to FY26, with Boss delivering its revised production and cost guidance for the year."
Dusci added:
While FY26 has been a challenging year for Boss, I am confident in our pathway forward and I look forward to outlining this in detail to the market with the release of our New Feasibility Study which supports an updated Life-of-Mine Plan…
The significant work programs completed, particularly since Boss committed to investigating the economic applicability of the wide-spaced wellfield design, are an endorsement of the technical capability and commitment of our team. I am excited for what this means for Honeymoon over the longer term.
Dusci also welcomed Peter Botten as incoming chair to the Boss Energy board. Botten will join the board on 30 September.
"Peter's depth of experience in large-scale resource development is highly relevant as we advance the Honeymoon operation," Dusci said.
