(http://pyrogenesis.com) (TSX VENTURE:PYR)(OTCQB:PYRNF), a high-tech company (the "Company" or "PyroGenesis") that designs, develops, manufactures and commercializes advanced plasma processes and plasma torch products, announces today that due to recent stock trading activity, and decrease in stock price, the Company contacted IIROC.

The Company is current on all its regular quarterly filings, has made (in advance) its third quarter interest payment due under its previously completed convertible debenture, and plans to report its third quarter results in November as required by the TSX Venture Exchange.

"We wish to reassure all of our stakeholders, and market participants, that the fundamentals of PyroGenesis, in terms of activities previously reported on, as well as the progress being made thereon, are not only sound but are moving forward as expected" said P.
