Boss Energy (ASX:BOE) has concluded its Honeymoon review and announced a new feasibility study, following significant deviations from the assumptions in its 2021 enhanced feasibility study.
The review revealed less continuity of higher-grade mineralisation, reduced leachability, and smaller wellfields than previously expected, which may materially affect life-of-mine production and costs from FY27.
As a result, Boss has formally withdrawn the 2021 EFS and advised it should no longer guide operational expectations.
Boss is exploring an alternative wide-spaced wellfield design, currently at a concept stage. Accelerated work programs have been initiated to assess its potential economic benefits.
An initial update is expected in Q1 2026, with a scoping study by Q2 2026 and the new feasibility study targeted for Q3 2026.
