Richard Seville

Executive Chairman

Career chronology

Education and qualifications

Mining and engineering education reported

Education; report published 23 March 2026 · issuer reported · low materiality

AEM’s annual report biography reports a BSc (Hons) in Mining Geology and a Master of Engineering Science in Rock Engineering. The issuer report does not provide a public primary credential verification.

Attribution: Responsibility not applicable. Qualifications are reported by the issuer; no external registrar confirmation was located in the documented search.

Relevance: Mining and engineering training is relevant to resource-sector board experience, though AEM is now a manufacturer.

Contributions and company outcomes

Orocobre lithium production increased during his CEO tenure

Financial years ended June 2017 and June 2018 · issuer reported · medium materiality

Orocobre reported Olaroz production of 12,470 tonnes of lithium carbonate in FY2018, up 5% from FY2017, while Seville was its managing director and CEO. Company revenues were also affected by lithium prices; these company results do not isolate his individual contribution.

Attribution: Role overlaps event; causation unproven. The records establish the senior role and concurrent company results, not that Seville alone caused them.

Relevance: Relevant prior exposure to scaling a critical-materials producer; valuation and volume outcomes cannot be transferred directly to AEM.

AEM has a commercial-size plant but the commercial ramp remains early

Six months to 30 June 2026; guidance and capacity clarification through 1 October 2026 · issuer reported · low materiality

AEM’s 2026 interim report records 12.5 tonnes of HPA sales, A$459,518 revenue and a A$13.42 million net loss for the first half of 2026. The September deck states 2,000 tpa nameplate capacity and forecasts 40–60 tonnes of H2 sales. On 1 October, Adams clarified that 2,000 tpa equipment capacity applied to the first two stages, with the final product-tailoring stage still needing additional equipment; capacity is not actual output and H2 sales were guidance at the evidence cutoff.

Attribution: Role overlaps event; causation unproven. Seville is Executive Chairman during the reported period; reports do not attribute the result or target to him personally.

Relevance: A relevant oversight result for a chair during a capacity-to-sales transition.

Industrial safety

Contractor died at Prominent Hill during OZ Minerals board tenure

September 2021; annual report published February 2022 · documented · medium materiality

SafeWork SA reported that a worker died after being crushed at Prominent Hill on 5 September 2021 and said it had commenced an investigation. OZ Minerals identified the worker as a Byrnecut contractor, and its 2021 report recorded a reduction in the CEO’s short-term incentive following the fatality. Seville was an independent OZ Minerals director and sustainability committee member during the period. The regulator’s final investigation or prosecution outcome was not located, and the sources do not establish individual involvement or personal fault by Seville.

Attribution: Role overlaps event; causation unproven. Seville’s director and committee role overlapped the incident; the sources do not attribute operational decisions, causation or fault to him.

Relevance: Material historical safety oversight context for a current executive chair.

OZ Minerals and contractor gave undertakings after separate unplanned blasts

October 2020; enforceable undertakings accepted 2022 · documented · medium materiality

SafeWork SA reported two unplanned underground explosions and fumes at Prominent Hill in October 2020. No injuries were reported. In 2022 the regulator accepted enforceable undertakings from OZ Minerals and Byrnecut involving safety improvements, with estimated commitments of A$156,845 and A$627,000 respectively. The regulator said no work-health-and-safety charges had been laid. Seville was a non-executive director during the incident; the available sources do not establish his personal involvement.

Attribution: Role overlaps event; causation unproven. An oversight-period company event and regulator response, not proof of personal conduct or a finding against Seville.

Relevance: Prior board oversight and safety-control context for an industrial-plant chair.

Suitability for the current role

Chair oversight experience is relevant; individual AEM results remain early

Current role at 31 October 2026 · analyst inference · low materiality

Analyst inference: a long executive and board career in ASX/TSX/AIM companies is relevant to chairing a small, scale-up HPA producer. Sources do not demonstrate that Seville personally delivered AEM’s plant or sales results.

Attribution: Responsibility not applicable. This is a role-scope assessment, not a claim of causation or personal integrity.

Relevance: Chair oversight is relevant while the plant scales and moves toward sustained sales.

Evidence gaps

  • Appointment history beyond the dates in the selected roster and issuer materials was not independently checked.

  • AEM biography claims about Allkem market-capitalization growth are issuer descriptions; individual causal contribution is not isolated.

  • Open-web searches documented here are not an exhaustive court, regulator, sanctions, criminal-record, reference or credential check.

  • The exact date his OZ Minerals directorship ended is unresolved; AEM says 2024 while Allkem’s 2023 annual report states May 2023; the 2023 report is the nearer contemporary source.

  • The final regulator, prosecution or coronial outcome concerning the September 2021 Prominent Hill fatality was not located in the reviewed searches.
