Natasa Mining Limited ("Natasa") announcement

ACU and ZCI note today's announcement issued by Natasa in respect of its acquisition of (i) bonds with a face value of BWP149.6 million (US$ 21 million) issued by ACU's wholly owned subsidiary Messina Copper (Botswana) (Proprietary) Limited ("Messina") (the "Bonds") and (ii) other indebtedness of Messina. The announcement also outlines Natasa's lodging of a petition with the High Court of Botwsana to seek an order for the provisional liquidation of Messina.

ACU confirms that Messina has been served with a copy of the petition and is currently reviewing its contents with ZCI. At this point, ACU intends to dispute the validity of certain claims made in the petition. In particular, both the quantum of the security interest which Natasa has over ACU's residential estate as well as the extent to which that interest encumbers the movable assets of Messina. ACU is confident that the petition can be defeated.

At no time since acquiring the bonds and other indebtedness of ACU and its subsidiaries has Natasa made any meaningful attempts to engage ACU in a dialogue concerning the indebtedness and it therefore appears that the indebtedness was acquired for the sole purpose of forcing a liquidation of Messina. In addition, following notification of the repayment date by Natassa on 7 May 2009 to pay the outstanding US$1.5 million bridge loan and US$2.3 million of trade debt acquired by Natassa, Natasa has frustrated ACU attemps to pay these amounts in full.

ACU and ZCI believe in the future of the Mowana mine and will consider their options and update the market in due course.
