COMMENTS BY AUDITORS FOR U.S. READERS ON CANADA-U.S. REPORTING DIFFERENCES

In the United States, reporting standards for auditors require the addition of an explanatory paragraph (following the opinion paragraph) when there is a change in accounting principles that has a material effect on the comparability of financial statements, such as the changes described in Note 1(m) and Note 8, to the Company's consolidated financial statements as at June 30, 2006 and 2005, and for each of the years in the three-year period ended June 30, 2006 and for the period from August 17, 1994 to June 30, 2006. Our report to the shareholders dated September 21, 2006, included in the annual report on form 40-F, is expressed in accordance with Canadian reporting standards which do not require a reference to such a change in accounting principles in the auditors' report when the change is properly accounted for and adequately disclosed in the financial statements.
