Evidence gaps

• Degree and professional-membership assertions are issuer-reported and have not been independently verified with the relevant institutions.

• The October 2026 search was limited to the precise terms recorded; all retrieved results were not exhaustively reviewed.

• Current Ausgold co-secretarial role at 31 October 2026, personal qualifications and prior career are not independently established.
