Haoma Miffing NL

Dear Stephen

I refer to our recent correspondence concerning the 10,000,000 ordinary shares in Haoma Mining NL (the "Shares) acquired by Alumina Limited (then named WMC Limited) in 1995 and still held by Alumina Limited.

In order to effect the correction of ownership of the Shares on the share registry to BHP Billiton Nickel West Pty Ltd (formerly WMC Resources Limited), Computershare has advised BHP Billiton that it will need to see evidence of the consent of ALumina Limited.

Accordingly, I would be grateful if you would reply on the enclosed duplicate of this letter in the place indicated evidencing the consent of Alumina Limited.

Yours sincerely

Anthony H Austin Senior Counsel BHP Billiton Legal
