PyroGenesis Announces Receipt of $1,372,000, Representing 2nd Progress Payment Under Contract with HPQ Silicon Resources

PyroGenesis Canada Inc. (https://pyrogenesis.com) (TSX VENTURE:PYR)(OTCQB:PYRNF), a clean-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 2^nd progress payment under a previously announced $8.3MM contract with HPQ Silicon Resources Inc. (“HPQ”) to provide a 200 metric tonne (MT) per year PUREVAP™ pilot system (the “System”) to produce silicon metal directly from quartz (the “Contract”). To date, PyroGenesis has received over CAN $2,862,000, or more than 34% of the value of the Contract.
As announced on August 2, 2016, the Contract is for the design, fabrication, assembly, commissioning and testing of the System. We currently are in the design, fabrication and assembly phase of which there remains approximately $2.6MM 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.

Management believes the PUREVAP™ 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%).
“The PUREVAP™ has the potential to change the silicon making industry by turning a complex multiple step process into a single step process,” said Pierre Carabin, Chief Technology Officer of PyroGenesis. “We are extremely pleased with the progress of the project to date and are looking forward to the completion of the System.”
“These results are significant as the prevailing proposition suggests that the quartz purity level required to make high purity silicon metal is over 99.5%⁴; however the PUREVAP™ has proven that to no longer be the case,” said P. Peter Pascali, President and CEO of PyroGenesis. “We have demonstrated that the System can use quartz of a significantly lower purity level (97.5%) as feedstock and still produce high purity silicon metal. The implications of this are enormous when considering the potential commercial applications of the PUREVAP™ process. Conceivably, we can now take an inexpensive and abundant low purity quartz feedstock and transform it into a high value end product.”
Figure 1 reflects the fundamental steps used in the conventional process, as compared to the PUREVAP™ process, to transform quartz into a solar grade silicon. To view Figure 1, please visit the following link: https://media3.marketwire.com/docs/1082485_Fig_1.jpg
As you may note, in the conventional process, an electric arc furnace is used to transform the quartz into metallurgical grade silicon (“MGS”), which is then dissolved in hydrochloric acid and after several additional steps, solar grade silicon is formed. Separately, the now obsolete Timminco Ltd. attempted to replace the hydrochloric acid step with a rotary furnace, thereby, in theory, form solar grade silicon without the additional steps required in the conventional process; however the significant difference between both these processes and the PUREVAP™ is that the PUREVAP™ process starts directly with quartz, which is introduced into a vacuum arc furnace with no additional steps required. The PUREVAP™ process does not have to create a MGS; it is all done in just one step, creating significant advantages.
