          SNC-Lavalin        Engineers  & Constructors Inc. (“SLE&C”) has no reasonable        ground to believe, and does not in fact believe, that there had been        a misrepresentation in the AIF in respect of the contents of the 40,000        t/d Feasibility Study or the 20,000 t/d Feasibility Study (jointly referred        to as the “Feasibility Studies”), provided, however, that SLE&C        has not reviewed the documents incorporated by reference in the AIF,        referred to as items (a) and (b), and this consent does not apply to        those documents.

          The        work and/or services described in the following portions of the Feasibility        Studies were performed, and the opinions in respect thereof are expressed        by others, and edited by SLE&C for consistency of format only:

          On page 20 of the AIF, under “Environmental Matters” the following statement appears:  “The feasibility studies conclude that, subject to  further analysis to be conducted at subsequent stages of the project, the risk of...schedule delays arising from environmental or socio-economic concerns...is low”.  Although there have subsequently been permitting delays, the present schedule is reflected under “Permits” on page 21 of the AIF.

          We also consent to the use of our name under the heading “Experts” in any filing of such AIF and Form 40-F.
