Under the terms of the Share Subscription Agreement, Astron has agreed to subscribe for a further 171 million shares at a price of A$0.02 per share to raise a further A$3.42m (“Tranche 2”). Tranche 2 is conditional upon Zambezi shareholder approval, requisite regulatory approvals in Zambia, the execution of a voluntary escrow agreement and the execution of the Convertible Note agreement (below). Completion of Tranche 2 is scheduled for early March 2009.

absolute discretion to elect to subscribe for the Note, to be exercised within three months after Zambezi shareholder approval

A notice of meeting for a shareholder meeting to consider the ratification of Tranche 1 and approval for Tranche 2 and the Note will be published in due course.

The board of Zambezi believes that the Transaction will secure necessary funding for the foreseeable future and at the same time provides the Company with a strategic investor. The Transaction will allow the Company to continue work on the exploration portfolio in Zambia.

Astron is listed on the ASX and located in Sydney, Australia, but also has a strong presence in China with an office in Shenyang. Astron’s interest in Zambezi is principally as a strategic opportunity to ultimately supply copper from Zambia into China leveraging off Zambezi’s copper/gold projects and facilitating Zambezi’s entry into Chinese markets. The transaction will ensure the survival of the Company and add longevity to its existing projects.

The Company's shares were suspended from trading on ASX on 31 October 2008 and AIM on 3 November 2008 pending clarification of the Company's financial position. The Company's shares will only be restored to trading following this clarification and a further announcement on this will be made following the general meeting to be held as detailed above.
