CAUTIONARY NOTE

Some of the statements contained in this report are forward-looking statements, such as estimates and statements that describe Placer Dome’s future plans, expectations, objectives or goals, including words to the effect that Placer Dome or management expects a stated condition or result to occur. Forward-looking statements may be identified by such terms as “believes”, “anticipates”, “intends”, “expects”, “estimates”, “may”, “could”, “would”, “will” or “plan”. Such forward-looking statements are made pursuant to the safe harbour provisions of the United States Private Securities Litigation Reform Act of 1995. Since forward-looking statements are based on assumptions and address future events and conditions, by their very nature they involve inherent risks and uncertainties. Actual results relating to, among other things, mineral reserves, resources, results of exploration, reclamation and other post-closure costs, capital costs, mine production costs, and Placer Dome’s financial condition and prospects, could differ materially from those currently anticipated in such statements by reason of factors such as the productivity of Placer Dome’s mining properties, changes in general economic conditions and conditions in the financial markets, changes in demand and prices for the minerals Placer Dome produces, litigation, environmental, legislative and other judicial, regulatory, political and competitive developments in domestic and foreign areas in which Placer Dome operates, technological and operational difficulties encountered in connection with Placer Dome’s mining activities, labour relations matters, costs and changing foreign exchange rates and other matters discussed under “Management’s Discussion and Analysis” or detailed in Placer Dome’s filings with securities regulatory authorities. This list is not exhaustive of the factors that may affect any of Placer Dome’s forward-looking statements. These and other factors should be considered carefully and readers should not place undue reliance on Placer Dome’s forward-looking statements. Further information regarding these and other factors which may cause results to differ materially from those projected in forward-looking statements are included in the filings by Placer Dome with the U.S. Securities and Exchange Commission and Canadian provincial securities regulatory authorities. “Placer Dome” is used in this report to collectively mean Placer Dome Inc., its subsidiary companies and its proportionate share of joint ventures. “Placer Dome’s share” is defined to exclude minority shareholders’ interest. The “Corporation” and “the company” refer to Placer Dome Inc.

Placer Dome does not undertake to update any forward-looking statement that may be made from time to time by Placer Dome or on its behalf, except in accordance with applicable securities laws.

This report on Form 6-K, dated September 3, 2004, is specifically incorporated by reference into Placer Dome Inc.’s registration statements on Form S-8 Nos. 33-17334, 33-21938, 33-21942, 33-27797, 33-91180, 333-05430, 333-10278 and 333-10274, respectively, and registration statement on Form F-10 No. 333-113870.
