Dear Sir/Madam

Re: Notice of initial substantial holder and change of interests of substantial holder – OZ Minerals Limited (OZL)

We attach a Form 603 and Form 604 ( Forms ) in relation to OZ Minerals Limited. Challenger Limited and its subsidiaries became a substantial holder on 29 October 2014. On 18 November 2014 there was a one percent change of interest in the security occurred. Due to an inadvertent data code entry error for the security, notices were not lodged at the relevant times. This data code error has been corrected. The Forms disclose all changes of relevant interests as at 2 December 2014.

Yours faithfully
