Boss Energy Advancing Operational Review of Honeymoon Uranium Mine with Wellfield Assessment
Boss Energy (ASX: BOE) has engaged in-situ leach mining experts as it advances an operational review of its Honeymoon uranium mine in South Australia.
The company initiated the review in late July 2025 after operating data identified some variability in mineralisation and leachability relative to previous feasibility study estimates for the project.
The primary purpose of the review is to identify any potential challenges to achieving nameplate capacity as previously outlined in the company’s 2021 enhanced feasibility study (EFS), with operating data suggesting some uncertainty regarding production and earnings for FY27 and beyond.
Wellfield Performance Studies
As part of the review, Boss has analysed the initial 12 months of actual performance and design for wellfields B1 to B5, as well as recent delineation drill results for development at East Kalkaroo’s B6 to B9 wellfields.
The company’s technical team is currently developing a program of work and timeline to undertake the review, which it expects to complete during the December quarter.
Along with the potential impact on the EFS assumptions and production volumes, the output from the review will include an assessment of the mineral resource and wellfield design.
Resource Drilling Accelerated
Boss has already elected to accelerate resource drilling to support the wellfields planning schedule, with work to commence in mid-September and take approximately seven to nine months to complete.
“We have moved quickly to appoint leading experts in their fields with the aim of establishing an accurate and independent assessment of our resources and optimum production rates,” managing director Duncan Craib said.
Releasing the recent annual report, chair Wyatt Buck noted that Boss had achieved a number of major milestones in FY25 as it transformed into a uranium producer, most notably exceeding its production and cost guidance at Honeymoon.
“In the process, our total production at the Honeymoon uranium operation passed one million pounds soon after the end of the financial year,” he added.
The company expects to become cash flow positive in FY26.
