PYROGENESIS COMMENTS ON YESTERDAY'S TRADING ACTIVITY

PyroGenesis Canada Inc. is issuing this press release in response to yesterday's unusual trading activity in its shares.

On Sept. 3, a significant number of company shares were offered for sale within a very short period of time, creating significant downward pressure on the stock. As a result, by the end of the day, over 1.3 million shares were traded, and PyroGenesis's stock closed down 6.5 cents to 25.5 cents after rebounding from a daily low of 24 cents.

On Sept. 2, PyroGenesis was contacted by a large bank, requesting assistance in finding a buyer for a significant number of company shares. The company was once again contacted Sept. 3 by the same bank with the same request, but, notwithstanding the company's attempts to assist in this matter, a significant number of shares were offered at increasingly lower prices throughout the balance of the day.

The company wishes to advise that the unusual selling pressure experienced yesterday seems to have been largely due to one seller, and that this selling was a result of unique issues faced by the seller, as opposed to any material change suffered by PyroGenesis.

"It is not my position to opine on the trading practices of investors," said P. Peter Pascali, president and chief executive officer of PyroGenesis. "However, it is important to note that nothing has transpired at the company over the last 48 hours, or that has not been disclosed, which would warrant such a rapid sell-off. Since a more orderly disposition of these shares would have likely netted the seller additional income, we can only assume that there were significant internal pressures on the seller which would have resulted in such an action, pressures unrelated to PyroGenesis itself. Last but not least, we wish to assure PyroGenesis's shareholders that we remain on track with our current and prospective projects and that, moreover, we expect to be cash flow positive by fourth quarter 2015."

We seek Safe Harbor.
