PyroGenesis Announces Receipt of CAN$531,600 Representing 4th Progress Payment Under Contract with HPQ Silicon Resources Inc.

MONTREAL, QUEBEC--(Marketwired - March 28, 2017) - PyroGenesis Canada Inc. (http://pyrogenesis.com) (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, announces today that it has received the 4^th progress payment under a previously announced $8.3MM contract with HPQ Silicon Resources Inc. ("HPQ") to provide a 200 metric tonne (MT) per year PUREVAPtm pilot system (the "System") to produce silicon metal directly from quartz (the "Contract"). To date, PyroGenesis has received payments in excess of CAN$3.9MM, or equivalent to more than 47% of the value of the Contract. 

As previously announced on August 2, 2016, the Contract is for the design, fabrication, assembly, commissioning and testing of the System. We are currently in the design, fabrication and assembly phase, of which there remains approximately $1.5MM to be paid subject to certain milestones; $520,000 in payments are due during the commissioning phase; with an additional $2.3MM to be paid following various milestones during the testing phase.

To date, PyroGenesis has demonstrated that the System can:

• Transform low purity quartz (97.5%) to high purity silicon; thereby defying standard methods¹;
• Successfully produce 4N (99.99%) silicon from low purity quartz²;
• Remove aluminum, boron, calcium and phosphorous with consistently high efficiencies, between 67 and 97%. Of particular note, boron, which negatively impacts the electrical properties of photovoltaic solar systems, is one of the most difficult impurities to remove from silicon³.
• Quantity produced per batch during testing phase increased from less than 0.1g to 8.8g, nearly a hundredfold increase⁴; and
• Reached a production of 4N+ purity Silicon Metal (99.99+% Si) using 98.14% SiO₂ by adding a solid purifying into the feedstock⁵.

Management continues to believe that the PUREVAPtm will have a significant impact on the solar industry. We note that there seems to be significant commercial applications for the System, at lower purity levels, as well (i.e. above 99.9%).

"At this stage, the design of the pilot system has progressed well and we have already delivered the Process Engineering Drawings and Mechanical Layout Drawings to the client," said Pierre Carabin, Chief Technology Officer of PyroGenesis. "The next step will be to delivery the complete Equipment Specifications Package, which is already well underway. We are extremely pleased with the progress of the project so far and are looking forward to achieving our stated goals."
