Boss Energy sticks to Honeymoon guidance: wet-season lessons for ISR engineers
Reviewed by Tom Sullivan

First reported on Australian Mining
30 Second Briefing
Boss Energy will keep its 2025–26 production guidance for the Honeymoon in-situ recovery uranium project in South Australia despite a rain-hit quarter that reduced output. Heavy rainfall disrupted wellfield access and slowed resin loading from the ion-exchange columns, temporarily constraining plant throughput. Management is banking on improved dry-season access and additional production wells coming online to recover volumes, signalling confidence in the leach circuit and groundwater management strategy rather than revising guidance after a single weather-affected quarter.
Technical Brief
- Elevated groundwater inflows likely demanded closer monitoring of hydraulic gradients to maintain leach containment and avoid excursions.
- Resin loading slowdowns in ion-exchange columns suggest reduced flow or altered chemistry, requiring tighter process control checks.
- Wet-season contingency planning now hinges on all-weather access tracks, drainage upgrades and more robust traffic management.
- Safety procedures for working around flooded sumps, ponds and process areas would need reinforcement and additional PPE controls.
Our Take
Boss Energy’s Honeymoon uranium project sits within a relatively small subset of our 1112 Mining stories that combine uranium with Safety and Projects tags, signalling that operational reliability and risk management are under closer scrutiny for Australian uranium developers than for many base-metal projects.
Maintaining guidance into the 2025/26 financial year despite weather disruption suggests Boss is targeting a ramp-up profile resilient to climate-related interruptions, an issue that has affected several Australian open-pit and ISR operations in our database over the past few wet seasons.
Among uranium-tagged pieces in our coverage, Australian projects like Honeymoon tend to progress without the geopolitical and permitting headwinds seen in some African and North American uranium stories, which can give operators here a relative advantage in locking in medium-term supply commitments.
