This news release contains "forward-looking information", as such term is
defined in applicable Canadian securities legislation, concerning
Timminco's future financial or operating performance and other statements
that express management's expectations or estimates of future

regarding the timing for release of financial information.
Forward-looking information is based on a number of assumptions and
estimates that, while considered reasonable by management based on the
business and markets in which Timminco operates, are inherently subject
to significant operational, economic and competitive uncertainties and
contingencies. Timminco cautions that forward-looking information
involves known and unknown risks, uncertainties and other factors that

generally; production capacity expansion at the Becancour facilities;
protection of intellectual property rights; increasing and maintaining
the purity of solar grade silicon; long-term contracts for supplying
solar grade silicon; selling prices for solar grade silicon; price
volatility for silicon metal; pricing and availability of raw materials

Although Timminco has attempted to identify important factors that could
cause actual results, performance or achievements to differ materially
from those contained in forward-looking information, there can be other

materialize. Accordingly, readers should not place undue reliance on
