  • Submitted  “Update on the PUREVAPâ„¢ progress report to HPQ Silicon Resources Inc.
  • 62% Increase in Impurity Removal
  • 531% Yield Increase

MONTREAL, QUEBEC–(May 16, 2017) – PyroGenesis Canada Inc. ( (TSX VENTURE:PYR)(OTCQB:PYRNF), a high-tech company (the “Company” or “PyroGenesis”) that designs, develops, manufactures and commercializes plasma waste-to-energy systems and plasma torch products, is pleased to announce today that, further to its press release dated January 26, 2017, it has submitted a progress report to HPQ Silicon Resources Inc. (“HPQ”) entitled “Update on the PUREVAPâ„¢ Process Characterization Testing #2“, which covers the period since the last technical report. The salient points of the report are significant in that they validate the systematic and methodical approach to the lab scale test purification work, and the scaling up of the process to convert quartz into high purity silicon metal.

The report confirms that recent, and ongoing, modifications to the PUREVAPâ„¢ process have resulted in: (i) a 62% improvement in the impurity removal capacity of the system using low purity quartz as feedstock and (ii) a 531% increase in yield of the silicon (Si) produced.

“We are pleased with the progress to date,” said Pierre Carabin, Chief Technology Officer of PyroGenesis. “We have now reached a stage where we can start testing using high purity feedstock which will allow us to validate the impurity removal capacity of the lab scale reactor and ultimately, to further improve the product purity.”

Having successfully secured access to high purity quartz (99.5% SiO2), the next phase will apply high efficiency impurity removal techniques to this higher purity feedstock. The objective of using a higher purity feedstock is to test the ability to reach the 5N (99.999%) benchmark at lab scale, and furthermore, to provide additional data which will help PyroGenesis with the final design of the pilot plant reactor. These tests will commence as soon as the latest process improvements are completed.

“These results demonstrate that the PUREVAPâ„¢ QRR quartz purification process can continue to be successfully improved while using low purity feedstock at the bench scale. This represents yet more important technical milestones being reached in our path toward production of Solar Grade Silicon Metal. At this stage of our development, we continue to pass critical milestones consistently and must continue our ‘iterative’ approach of incrementally increasing size, and purity step by step”, said Bernard Tourillon, Chairman and CEO of HPQ. “Building on our scaling up success to date, the coming months should allow us to continue to make improvements to our scaling up program, while simultaneously testing for the best and greenest pathway to produce 5N (99.999% Si) Solar Grade Silicon Metal at lab scale, prior to start-up of the Pilot plant scheduled for 2018.”
