ASX Announcement

ORICA KOORAGANG ISLAND UPDATE

Orica Limited is pleased to announce the resumption of ammonia production at Kooragang Island.

The plant closures (both ammonia and ammonium nitrate) are estimated to have adversely impacted earnings before interest and tax by approximately $90M this financial year. This will impact earnings in the first half of the financial year; however, in the light of strong underlying demand conditions, the Company continues to expect that Group net profit after tax (pre individually material items) to be higher than that reported in 2011, for the year ending 30 September 2012, subject to global economic conditions .
