ioneer Ltd director Timothy Roy Woodall reported an open-market purchase of 200,000 Ordinary Shares of the company. The shares were bought at an average price of $0.108 per share.

The updated figure includes 188,083 Ordinary Shares underlying time-based units that vest on November 2, 2026 and 200,000 Ordinary Shares underlying time-based units that vest on May 4, 2028. This filing does not reflect a new trade but a correction to prior disclosure.
ioneer Ltd filed a Form 6‑K providing its 2025 Corporate Governance Statement and an Appendix 4G cross‑referencing ASX governance recommendations. The Board operates under formal charters, with four standing committees covering audit and risk, nominations and remuneration, project execution and environmental, health, safety and sustainability.
The Board has a majority of independent non‑executive directors, although the Executive Chair is not considered independent. Ioneer reports gender diversity across the organisation and has a formal diversity policy, but does not set measurable gender targets because of legal and regulatory constraints in some jurisdictions. The company highlights risk oversight for its planned Rhyolite Ridge project in Nevada, uses an external auditor but has no formal internal audit function, and maintains policies on continuous disclosure, whistleblowing, and anti‑bribery and corruption.
