Australian uranium producer Boss Energy (ASX:BOE) has signaled a significant shift in its operational efficiency, slashing its annual cost guidance following a record-breaking December 2025 quarter at the Honeymoon project in South Australia.
The company reported record drummed production of 456,000 pounds of triuranium octoxide, representing an 18% surge over the previous quarter.
This performance was largely attributed to higher flow rates from newly commissioned wellfields and optimised reagent consumption, which helped drive the site’s C1 cash costs down by 12% to US$20 per pound.
Consequently, Boss has revised its full-year C1 cost guidance to a range of U$S24–US$26 per pound, a notable decrease from the earlier US$27–US$29 estimate.
While the South Australian operations flourished, the company’s joint venture in Texas, the Alta Mesa Project, saw a 31% decline in total production on a 100% basis.
However, Boss' attributable share of that output rose by 51%, reaching 68,000 pounds.
Despite these varying regional results, the company remains firmly on track to meet its full-year production target of 1.6 million pounds.
Boss maintains a solid cash position and is moving forward with a new feasibility study aimed at extending mine life and further lowering long-term costs through redesigned wellfield layouts.
