About DST

DST is the developer and owner of proprietary technologies to serve the natural resource sector with environmentally friendly procedures. The cyanide and mercury free gold extraction process developed by DST, has been recognized as a "green technology" for which DST has been awarded $5,700,000 in grants to date for a demonstration plant, presently under construction in Thetford Mines Quebec of which $700,000 has been provided by the Government of Quebec and $5,000,000 by the Government of Canada through the Sustainable Development Technology Fund.

Over the last ten years DST has tested over 50 different gold deposits, both oxide and sulfide ores at the lab level and at its pilot plant. These tests have, consistently achieved gold recoveries in excess of 90%, using chlorination instead of cyanide. In addition, the tailings from the process are inert from toxic substances and as result meet environmental norms. An engineering study supports DST's claim of having operated a pilot plant showing a gold extraction yield higher than 90% using a closed-circuit chlorination process.

The Canadian Securities Exchange has in no way passed upon the merits of the proposed transaction and has neither approved nor disapproved the contents of this press release.
