PyroGenesis Submits Gen 2 PUREVAP™ Progress Report to HPQ Silicon Resources Inc.; Confirms Higher Yield and Rate

MONTREAL, Jan. 15, 2018 --

PyroGenesis Canada Inc. (http://pyrogenesis.com) (TSX-V: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 it has submitted to its client, HPQ Silicon Resources Inc. (“HPQ”), a report entitled “Project Progress on GEN 2 PUREVAP”.

This report gives a summary of the first five (5) tests on the Gen 2 PUREVAP tests.  The main results of these initial tests are:

• The Gen 2 PUREVAP can operate semi-continuously as designed and under vacuum. To our knowledge, this is the first time that this has ever been achieved.
• The Gen 2 PUREVAP provides a higher production yield and rate (5.7 times more yield and 23 times more product).
• The heat efficiency of the GEN2 is much better than GEN1. GEN2 achieves higher temperatures (i.e. more heat goes towards the process rather than being lost to various system components) and which allows for higher rate silicon production reactions and higher product purity.

“These initial Gen 2 results confirm the hypothesis we formulated when we initially designed this new reactor for higher yield and better performance.  The results also provide confirmation of our design parameters for the upcoming pilot phase of the project,” said Pierre Carabin, CTO of PyroGenesis.  “The next step will be to continue increasing the amount of material produced with the goal of being able to extract liquid metal directly from the reactor in operation.”

PyroGenesis has been engaged by HPQ to demonstrate, on a laboratory scale, that the PUREVAP™ process can produce high purity silicon metal from quartz in a one step process. Pursuant to a Can$8.3 MM contract signed with HPQ in August 2016, PyroGenesis is designing, fabricating, assembling, commissioning and testing a PUREVAP™ pilot system to produce silicon metal directly from quartz. The aim of the Gen 2 PUREVAP™ metallurgical testing program is to confirm previous findings, and to allow for downstream product testing as final steps are being put in place to assemble the Pilot Plant.
