QUALIFIED PERSON

	2. 	  	My
residential address is: 138 Hensman Street, South Perth, WA, Australia.  

	3. 	  	I
graduated with a Bachelor’s Degree in Mining Engineering from the
          University of Queensland, Australia, in 1988. In addition, I was awarded a
          Graduate Diploma in Business by Curtin University in Western Australia in 2000

have read the definition of “qualified person” set out           in National
Instrument 43-101 (“NI 43-101”) and certify that by reason           of my
education, affiliation with a professional association (as defined in NI

 activities and prepare reports for the management of the issuer.  

	9. 	  	I
am not aware of any material fact or material change with respect to the
          subject matter of the Technical Report that is not reflected in the Technical
