Environmental record

Costerfield operator faces tailings charges

December 2024 events; charges January 2026; annual report August 2026 · alleged · medium materiality

Resources Victoria said in January 2026 that it charged Mandalay’s Costerfield operator over alleged overfilling of two tailings facilities, identified in December 2024. Alkane acquired the operation in August 2025. Its 2026 annual report describes proceedings and says it expected resolution within six months of its August report; no final disposition was located. These are allegations against the operator, and no personal misconduct is established.

Attribution: Role overlaps event; causation unproven. Self was GM during the cited period; Earner led Alkane after the acquisition. Neither source establishes personal conduct or culpability.

Relevance: Material environmental oversight and integration context.

Evidence gaps

  • Independent verification of reported qualifications and full employer/appointment chronology was not obtained.

  • Open-web searches are limited; company events do not establish individual responsibility.

  • Final disposition of the Costerfield tailings proceedings was not located in searches through cutoff.

  • Separate topic-specific adverse and prior-employer searches were not completed; the combined batched search results were truncated, so this screening is incomplete.
