 to the SEC Disclosure Rules which differ from the requirements of NI 43-101 and the CIM Standards.

The SEC Disclosure Rules recognize estimates of "measured mineral resources", "indicated mineral resources" and "inferred mineral resources." In addition, the SEC Disclosure Rules incorporate definitions of "proven mineral reserves" and "probable mineral reserves". The definitions are "substantially similar" to the corresponding CIM Standards that are required under NI 43-101. While the SEC recognizes "measured mineral resources", "indicated mineral resources" and "inferred mineral resources", U.S. investors should not assume that any part or all of the mineralization in these categories will ever be converted into a higher category of mineral resources or into mineral reserves. Mineralization described using these terms has a greater amount of uncertainty as to its existence and feasibility than mineralization that has been characterized as reserves. Accordingly, U.S. investors are cautioned not to assume that any measured mineral resources, indicated mineral resources, or inferred mineral resources that the Company reports are or will be economically or legally mineable. Further, under SEC standards, the geological uncertainty associated with "inferred mineral resources" is too high to apply relevant technical and economic factors likely to influence the prospects of economic extraction in a manner useful for evaluation of economic viability. Under both United States and Canadian securities laws, estimates of "inferred mineral resources" may not form the basis of feasibility or pre-feasibility studies. While the above terms are "substantially similar" to CIM Standards, there are differences in the definitions under the SEC Disclosure Rules and the CIM Standards. Accordingly, there is no assurance any mineral reserves or mineral resources that the Company may report as "proven mineral reserves", "probable mineral reserves", "measured mineral resources", "indicated mineral resources" and "inferred mineral resources" under NI 43-101 would be the same had the Company prepared the reserve or resource estimates under the SEC Disclosure Rules.
