Important Cautionary Note Regarding Canadian Disclosure Standards

The Company is an 'OTC Reporting Issuer' under BC Instrument 51-509, Issuers Quoted in the U.S. Over-the-Counter Markets, promulgated by the British Columbia Securities Commission. Accordingly, certain disclosure in this news release or other disclosure provided by the Company has been prepared in accordance with the requirements of securities laws in effect in Canada, which differ from the requirements of United States securities laws. In Canada, an issuer is required to provide technical information with respect to mineralization, including reserves and resources, if any, on its mineral exploration properties in accordance with Canadian requirements, which differ significantly from the requirements of the United States Securities and Exchange Commission (the 'SEC') applicable to registration statements and reports filed by United States companies pursuant to the Securities Act of 1933, as amended, or the Securities Exchange Act of 1934, as amended. As such, information contained in this news release or other disclosure provided by the Company concerning descriptions of mineralization under Canadian standards may not be comparable to similar information made public by United States companies subject to the reporting and disclosure requirements of the SEC. This news release or other disclosure provided by the Company may use the terms 'measured mineral resources', 'indicated mineral resources' and 'inferred mineral resources'. While these terms are recognized and required by Canadian regulations (under National Instrument 43-101, Standards of Disclosure for Mineral Projects), the SEC does not recognize them. United States investors are cautioned not to assume that any part or all of the mineral deposits in these categories will ever be converted to reserves. In addition, 'inferred resources' have a great amount of uncertainty as to their existence and economic and legal feasibility. It cannot be assumed that all or any part of an inferred mineral resource will ever be upgraded to a higher category. Under Canadian securities legislation, estimates of inferred mineral resources may not form the basis of feasibility or pre-feasibility studies, or economic studies, except in rare cases. U.S. investors are cautioned not to assume that part or all of an inferred resource exists, or is economically or legally mineable.
