Cautionary Note to US Investors Regarding Mineral Reporting Standards:
Northgate prepares its disclosure in accordance with the requirements of securities laws in effect in Canada, which differ from the requirements of US securities laws.

The Corporation uses certain terms, such as, "measured mineral resources", "indicated mineral resources", "inferred mineral resources" and "probable mineral reserves", that the SEC does not recognize (these terms may be used in this press release and are included in the Corporation's public filings which have been filed with securities commissions or similar authorities in Canada).
