Industrial safety

ANTAM reported zero fatalities and four medical-treatment cases in 2025

2025 · issuer reported · low materiality

The annual report lists zero fatalities and four Medical Treatment Cases for 2025 and reports a TRIR of 0.03. Hartono’s ANTAM operational leadership overlaps the year, but these are company-wide metrics; the report does not connect a specific safety result or incident to him.

Attribution: Role overlaps event; causation unproven. No individual act, control failure or causal contribution is established.

Relevance: Relevant oversight context for an executive with an operations background; not a personal safety record.

Environmental record

ANTAM reported two Gold PROPER awards for 2022–23

2022–2023 · issuer reported · low materiality

ANTAM reported Gold PROPER recognition for its Nickel Mining Business Unit and Precious Metal Processing & Refinery Business Unit and quoted Hartono. The source describes company/unit awards and does not isolate his personal contribution.

Attribution: Role overlaps event; causation unproven. The release quotes him but does not establish that he personally caused the awards.

Relevance: Limited positive environmental-management context for the current resource-management director.

Litigation and enforcement

Questioned as a witness in the 109-ton gold-management investigation

2010–2022 alleged events; witness examination 7 September 2023; convictions reported May 2025 · documented · medium materiality

IPOL reported that the Attorney General’s Office examined Hartono as a witness on 7 September 2023 in an alleged gold-business governance matter covering 2010–22; the report said no suspects had been announced at that time. Later ANTARA reports describe convictions of six former ANTAM precious-metals unit officials and seven private parties. Hartono is not among the named defendants in those reports. His witness examination does not establish an allegation or culpability.

Attribution: Individual involvement documented. Sources connect him to the investigation only as a witness. The later named defendants are distinct people; no personal charge or conviction against Hartono is established in reviewed materials.

Relevance: Relevant governance context given his later operating/director roles; individual involvement beyond witness evidence remains unproven.

Suitability for the current role

Geology, resource-management and exploration roles align with current portfolio

1996–2026 · analyst inference · medium materiality

ANTAM reports a Geological Engineering degree, a master’s in Mining and Mineral Resources Development and a Qualified Registered Geologist credential. Its career history includes Geomin exploration leadership, Gag Nikel, nickel business-unit management and operations/production leadership before the 2026 title change. These are issuer-reported qualifications and roles, not independently validated credentials or quantified results.

Attribution: Responsibility not applicable. Company biography supports chronology; credentials and individual outcomes were not independently checked.

Relevance: Strong apparent technical fit for resource management at a diversified miner, with evidence mainly issuer-reported.

Evidence gaps

• The IPOL article was accessible only via indexed text after a direct-page timeout; the witness lead should be treated with that source limitation.

• The 2010–22 gold investigation overlaps a long ANTAM career, but sources reviewed do not establish Hartono’s role in the alleged transactions; later convicted defendants were other people.

• Credential standing and independent individual operating, safety and environmental outcomes were not verified.

• No exhaustive litigation, sanctions or regulator-register check was performed.
