Strategic direction and operational transformation

• Transitioned to a wide-spacing wellfield design, reducing wellfield infrastructure by 50% and all-in sustaining costs by AUD 30/lb, while increasing PLS head grade by 28%.

• Developed a robust New Feasibility Study, enabling a shift from grade-focused to system-focused resource evaluation, especially for Gould's Dam and Jason's.

• Positioned Honeymoon as a central production hub, integrating Gould's Dam and Jason's deposits for scalable, low-capital growth.

• Aspires to ramp up production to 2.5Mlbs U3O8 per year at an AISC of A$65/lb by the early 2030s, significantly lowering unit costs and extending mine life.

• Enhanced technical and operational capacity with a new, globally experienced team and board renewal.

Operational performance and optimisation

• Honeymoon operation restarted in April 2024, achieving commercial production in January 2025, with 1.41Mlbs produced in FY26.

• Ongoing plant debottlenecking and staged upgrades aim to lift water treatment capacity and support higher production rates.

• Continuous improvement initiatives target reagent optimisation, wellfield efficiency, and infrastructure reuse to further lower costs.

• Safety culture and operational excellence are emphasized, with ISO 45001-aligned systems and direct leadership accountability.

• Continuous improvement programs have reduced costs and increased recovery rates, with further initiatives planned.

Resource base and development pipeline

• Combined mineral resource of 65.9Mlbs U3O8 across Honeymoon, Gould's Dam, and Jason's Deposit, with significant potential for further extension.

• Gould's Dam and Jason's Deposit are considered amenable to wide-spaced ISR, with ongoing drilling and permitting to upgrade and expand resources.

• FY27 delineation drilling programs at both satellite deposits aim to increase resource confidence and support future production.

• Regional exploration pipeline targets new ISR-amenable discoveries within the Honeymoon catchment.

• Development timeline targets production from Jason's Deposit by early 2030 and Gould's Dam by early 2031, subject to permitting and board decisions.
