PyroGenesis Provides Update on the PUREVAP™ QRR Project with HPQ Silicon Inc.

MONTREAL, Feb. 02, 2023 (GLOBE NEWSWIRE) -- PyroGenesis Canada Inc. ( (TSX: PYR) (NASDAQ: PYR) (FRA: 8PY), a high-tech company (hereinafter referred to as the “Company” or “PyroGenesis”), that designs, develops, manufactures and commercializes advanced plasma processes and sustainable solutions to reduce greenhouse gases (GHG) and address environmental pollutants, is pleased to provide, further to HPQ Silicon Inc’s (“HPQ” or the “Client”) press release dated January 19th 2023, and the Company’s news release on November 8, 2022, an update on its Gen3 PUREVAP™ Quartz Reduction Reactor (QRR) pilot plant (the “ Gen3 PUREVAP ™ Pilot Plant” or the “Pilot Plant”) project following recent inquiries from investors.

The process testing referred to in the HPQ press release dated January 19th, 2023, is moving forward as expected and represents, in management’s opinion, a key development in the overall project. These tests are geared to not only confirm that the technology works as expected, but also to give input into the subsequent engineering study which will be geared to determining amongst other things, the actual number of systems required for commercialization and the profitability of each.

“The question that keeps being asked of us is what does successful testing ultimately mean to PyroGenesis?”, said Mr. P. Peter Pascali, CEO and Chair of PyroGenesis, “The answer is that besides the strategic investment PyroGenesis has in HPQ, the Company also benefits from a royalty payment representing 10% of the Client’s sales. In addition to this, the subsequent commercial systems required by HPQ for commercialization would be manufactured by PyroGenesis. Although these current tests and the subsequent engineering study will determine the profitability of the project, they will also determine the exact number of reactors required. To give more clarity, at this stage both HPQ and PyroGenesis agree, given what we know today, that at least two (2) initial reactors, each reactor capable of producing 2,500 MT of high purity silicon per year, at a build cost to HPQ of at least $20 million each, would be required. This assumes successful testing which, although we are confident in, is not guaranteed as there are many uncertainties yet to be addressed before we can say with confidence that we have a successful process to commercialize.”

The PUREVAP™ process is an innovative patented process that will enable the one-step conversion of quartz (SiO2) into high-purity silicon (Si) at reduced costs, energy input and carbon footprint that will propagate its considerable renewable energy potential. As part of the terms of the contract with HPQ, PyroGenesis benefits from a royalty payment representing 10% of the Client’s sales, with set minimums.

About HPQ Silicon

HPQ Silicon Inc. (TSX-V: HPQis a Quebec-based innovative silicon solutions company that offers innovative silica (SiO2), silicon (Si) based solutions and is developing a unique portfolio of high value-added silicon (Si) products sought after by battery and electric vehicle manufacturers.

Silicon (Si), also known as silicon metal, is one of today’s key strategic materials needed for the decarbonization of the economy and the Renewable Energy Revolution (“RER”). However, silicon does not exist in its pure state and must be extracted from quartz (SiO2) in what has historically been a capital and energy-intensive process.

With PyroGenesis Canada Inc. (TSX: PYR(NASDAQ: PYR), HPQ is developing:

  1. the PUREVAP™ “Quartz Reduction Reactors” (QRR), an innovative process (patent pending), which will permit the one-step transformation of quartz (SiO2) into high purity silicon (Si) at reduced costs, energy input, and carbon footprint that will propagate its considerable renewable energy potential.
  2. Through its 100% owned subsidiary, HPQ NANO Silicon Powders Inc., the PUREVAP™ Nano Silicon Reactor (NSiR) is a new proprietary process that can use material produced by the QRR as feedstock, to make a wide range of nano/micro spherical powders of different sizes and nanowires.
  3. Through its second 100% owned subsidiary, HPQ Silica POLVERE Inc., HPQ is developing a new plasma-based process that will allows a direct Quartz to Fumed silica transformation, removing the usage of hazardous chemical in the making of Fumed silica and eliminating the Hydrogen Chloride Gas (HCI) associated with its manufacturing.
