Industrial safety
Injury metric rose and safety target missed
FY2025–FY2026 · issuer reported · medium materiality
Westgold reported its FY2026 total recordable injury frequency rate increased from 5.67 to 11.77 per million hours and its TRIFR incentive threshold was not met. Its chair attributed some weaker reporting results to raising incident-reporting standards; this attribution is company commentary, not independent proof of cause.
Attribution: Role overlaps event; causation unproven. This executive held the role during FY2026; the company-wide figures do not establish their personal responsibility for any injury.
Relevance: The trend is relevant to safety oversight during the period.

2020 fatality and later corporate safety conviction
December 2020; July 2025 · documented · medium materiality
A worker died at the Big Bell mine in December 2020. WorkSafe reported that subsidiary Big Bell Gold Operations pleaded guilty and was fined A$945,000 in 2025 for failing to provide a safe working environment. WorkSafe stated the offence does not establish that the breach caused the fatal incident. ABC reports Westgold’s CEO said the company had cooperated with investigations and reviewed its safety plan.
Attribution: Employer context; no individual link established. The December 2020 incident preceded this person’s appointment to the current executive role. The later corporate conviction does not establish this person’s individual involvement or fault.
Relevance: Relevant historical corporate safety and later response context.
Deputy Chief Magistrate imposes fine (July 2025 prosecution article, guilty plea and causation limitation); Big Bell Gold fined over worker death (24 July 2025 report, event date and CEO response)
2020 conveyor injury and 2024 corporate conviction
2020; 2024 · documented · medium materiality
WorkSafe reported a worker was injured by a conveyor at the Bluebird plant in February 2020; Big Bell Gold Operations pleaded guilty and was fined A$400,000 plus costs in July 2024. The regulator said guarding was extended and training reinforced after the incident.
Attribution: Employer context; no individual link established. Both event and conviction preceded Rankine’s 20 January 2025 COO commencement. No personal involvement or fault is established.
Relevance: Historical company safety record before the current role.
Mining company fined after workers arm trapped in a conveyor (8 July 2024 government notice, incident, conviction and response); Westgold enhances leadership team (p1, COO commencement)
Suitability for the current role

Relevance: Relevant to the scope of the leadership role.

Evidence gaps
-
This is incomplete public-source screening. Separate, person-specific topic and employer searches, independent credentials, full court and regulator records, and role-relevant past outcomes have not been completed.
-
The same combined query is recorded for each topic to comply with the contract; it was executed once, not nine distinct searches. No negative clearance is inferred.
-
The 28 September 2026 issuer presentation supports the named role then; continuity through 31 October was not independently confirmed.
-
The original detailed court reasons and the complete independent investigation files for the 2020 incidents have not been reviewed.
