Full background report

Olivier Regnault

Wellfields Technical Lead

Career chronology

Education and qualifications

PhD in hydrogeology and geochemistry

Education; reported by cutoff · issuer reported · medium materiality

Boss reports that Regnault holds a PhD in Hydrogeology and Geochemistry; the FY2026 earnings-call transcript identifies Mines Paris-PSL in his education remarks, and his research profile lists corresponding education. The exact award date and independent university credential verification were not located.

Attribution: Responsibility not applicable. Education is relevant to ISR and groundwater work; the transcript and profile are not primary degree records.

Relevance: Supports specialist technical fit while leaving credential verification incomplete.

Personal achievements

Co-authored peer-reviewed ISR reactive-transport research

2022 · documented · low materiality

A 2022 Hydrometallurgy paper on three-dimensional reactive-transport simulation for a large-scale uranium in-situ recovery wellfield lists Olivier Regnault as a co-author. This documents a technical research contribution; the paper does not establish sole authorship, operational implementation or a resulting production outcome.

Attribution: Individual involvement documented. Co-authorship is documented; no sole responsibility or commercial result is inferred.

Relevance: Adds independent technical evidence relevant to ISR modelling and wellfield work.

Suitability for the current role

ISR hydrogeology and technical research support wellfields role fit

Career through 2026-10-10 · analyst inference · medium materiality

Issuer disclosures describe more than 15 years in uranium operations and a PhD in hydrogeology/geochemistry. A peer-reviewed ISR reactive-transport paper lists Regnault as co-author, and a self-reported profile adds prior AREVA, KATCO and Orano roles. These sources support relevant specialization but do not independently establish his personal operating results; title variants remain unresolved.

Attribution: Responsibility not applicable. The paper demonstrates co-authorship only; it does not establish responsibility for mine outcomes or current site events.

Relevance: ISR, groundwater and wellfield expertise is directly relevant to Honeymoon; tenure and role-scope details remain issuer/self-reported.

International ISR and uranium-operations experience

By September 2025 · analyst inference · medium materiality

Boss reports more than 15 years in mining operations across Kazakhstan, France, Canada and Africa and expertise in uranium in-situ leach, mine planning and modelling. The Oct-2025 presentation identifies KATCO in Kazakhstan and Orano as prior employers and a former KATCO managing-director position; individual operational results in those roles were not separately corroborated.

Attribution: Responsibility not applicable. The sources establish background and technical remit, not personal accountability for employer-level operating outcomes.

Relevance: Directly relevant to wellfield performance and groundwater process at Honeymoon.

Evidence gaps

  • Exact education award date and independent degree verification were not obtained; the education source is company/transcript/profile rather than a university record.

  • Self-reported KATCO/Orano role dates and the former Managing Director title were not independently verified; current title varies across issuer sources.

  • The 2022 co-authored paper demonstrates research publication, not personal operational outcomes at KATCO, Orano or Boss.

  • Foreign regulator, court, sanctions and criminal databases across the disclosed jurisdictions were not systematically searched; no clearance is implied.
