firb exetnds 90 days, page-3

OZ Minerals has today been advised that the evaluation period for consideration of the application by
China Minmetals Non-Ferrous Metals Company Limited (“Minmetals”) for approval to acquire all the
shares in OZ Minerals under the Foreign Acquisitions and Takeovers Act (“Act”) has been extended by up
to 90 days from 24 March 2009.
OZ Minerals understands the requirement for proper process to be followed and will continue to work
co-operatively with the Foreign Investment Review Board. It is in the interests of OZ Minerals, its
shareholders, employees and all its stakeholders that the Minmetals’ application is determined as soon as
possible.
As previously advised, OZ Minerals is seeking an extension for the refinancing date for certain of its
banking facilities until 15 September, which is two weeks after the End Date, being the latest
implementation date currently permitted under the Scheme Implementation Agreement (“SIA”) with
Minmetals. This time period was set under the SIA to allow for the contingency that the evaluation period
under the Act may be extended beyond 30 days. OZ Minerals will continue negotiations with its lenders
to achieve the extension required.
Separately, the Australian Competition and Consumer Commission has advised that it does not propose
to intervene on the matter under section 50 of the Trade Practices Act.
OZ Minerals will request the Australian Stock Exchange lift the trading halt currently placed on the
Company’s shares.
