The latest update is out from Macarthur Minerals Ltd. ( (AU:MIO) ).
Macarthur Minerals has appointed William Buck (Qld) as its new external auditor, effective 24 April 2026, following the resignation of RSM Australia Partners and regulatory consent. The company stated there were no disagreements with the outgoing auditor, describing the change as part of its periodic review and rotation of external auditors under its corporate governance practices, with formal shareholder approval to be sought at the next annual general meeting.
The appointment of a new auditor underscores Macarthur’s emphasis on governance oversight as it progresses its iron ore and lithium assets in Western Australia. Stable audit arrangements and an orderly transition are likely to reassure investors and other stakeholders that the company’s financial reporting and compliance processes remain robust and aligned with regulatory expectations.
