OZ Minerals has a number of codes and policies in place to guide the Board and all employees in the application of our values to all day-to-day activities. These include the OZ Minerals Code of Conduct, Whistleblower Policy and Securities Trading Policy, all of which were reviewed and updated following the merger. These are made available to the OZ Minerals workforce via the intranet and are also available on the OZ Minerals website.

The Code of Conduct describes standards for appropriate ethical and professional behaviour for all directors, employees and contractors working for OZ Minerals. The Code provides policy on conflicts of interest, bribery and corruption, consumer and personal privacy and anticompetitive behaviour. Breaches of the Code are taken seriously by OZ Minerals and may be reported using the Whistleblower Policy.

OZ Minerals is committed to ensuring concerns regarding illegal conduct or malpractice can be raised in good faith without being subject to victimisation, harassment or discriminatory treatment, and to have such concerns properly investigated. The Whistleblower Policy provides a mechanism by which all employees can confidentially report improper or illegal conduct without fear or discrimination.

To safeguard against insider trading, OZ Minerals’ Securities Trading Policy prohibits directors and employees from trading the company’s securities if they are aware of any information that would be expected to have a material effect on the price of Company securities. The policy also establishes ‘black out periods‘, during which directors and employees must not trade OZ Minerals securities
