Dear Colleagues,

Maintaining our commitment to the OZ Minerals Code of Conduct is an important step in working towards achieving our vision, mission and business objectives. At OZ Minerals we have a whistleblower program that empowers you to play an active role in the elimination of improper conduct in the workplace.

This program now provides access to Stopline, a confidential, independent provider of whistleblowing services who will take full details of your concerns via telephone, mail, email, fax or this website. It is also important to remember our program enables individuals to maintain anonymity should they so desire. Stopline is available to all OZ Minerals employees, contractors or designated stakeholders and translation services can be provided if requested.

As well as the disclosure process, the website provides access to our Code of Conduct, Speak Up Procedure and answers to some of the most frequently asked questions for your reference. I believe that good corporate governance has the capacity to differentiate us from our competitors and enhance our reputation in the eyes of our clients and this website is just another example of OZ Minerals commitment to best practice.
