Environmental record

Cadia 2018 tailings containment incident

2018–2020 · issuer reported · medium materiality

Newcrest’s technical report says the northern tailings facility embankment slumped in March 2018, releasing material into a southern facility; a 2019 independent panel attributed the dominant location factor to a previously unidentified weak foundation unit. Capstone reported that Potts held several roles at Cadia over 13 years; her exact position in March 2018 is not established.

Attribution: Employer context; no individual link established. No role on the tailings facility or personal causation is established.

Relevance: Prior-employer safety and environmental context.

Evidence gaps

• Independent identity, career and credential verification remains incomplete.

• Targeted searches do not establish absence of adverse records or exhaust applicable court, regulatory and local-language sources.

• Precise Cadia role and responsibility in March 2018 are unverified.

• The full appointment and current role history, previous employment and credentials require additional corroboration.

• The prior per-person topic search log could not be verified against retained execution records. Topic coverage and absence of adverse records are not established.

• Capstone disclosures conflict on the Pinto Valley start: 2022 versus January 2023.
