HPQ Silicon Inc. PUREVAP(TM) Pilot Plant Testing Enters Reactor Startup Phase

MONTREAL, Sept. 07, 2022 - HPQ Silicon Inc. (“HPQ” or the “Company”) (TSX-V: HPQ) (OTCQX: HPQFF) (FRA: O08), an innovative silicon solutions and technology development company, would like to inform shareholders of a significant milestone achieved in the ongoing PUREVAPTM Pilot Plant testing process, as reported in our August 10, 2022 release. Technology provider PyroGenesis Canada Inc. (TSX: PYR) (NASDAQ: PYR) (FRA: 8PY) has completed the GEN3 PUREVAPTM Quartz Reduction Reactor (QRR) Pilot Plant system integration validation phase. This first phase is a key milestone of the research and development program.

HPQ GEN3 PUREVAPTM QRR PILOT PLANT R&D TESTING PROGRAM ADVANCING ON SCHEDULE
The GEN3 PUREVAPTM QRR Pilot plant is a first-of-its-kind, state of the art prototype comprised of multiple systems that must operate under harsh conditions, extremely high temperatures and under vacuum. With the systems integration now completed, the next milestones in PyroGenesis’ meticulous approach are:

a) Reactor start-up, a duration of about one (1) month will be allocated to this phase,

b) Four (4) process improvement tests, a duration of about two (2) months will be allocated to this phase, and

c) Operating the GEN3 QRR continuously, with non-stop production, during the remaining time.

As with all R&D projects, particularly with new process technology, the timeline is subject to change. PyroGenesis is confident that the program will allow HPQ to validate and quantify the previously completed GEN1 and GEN2 PUREVAPTM QRR testing phase results:

i. Produce Silicon (Si) material of higher purity than any traditional processes, in a single step1,

ii. That it can do so from raw material sources without the need for extremely pure feedstock as required by conventional processes2,

iii. That it only requires 4.5 MT of raw material to make 1 MT of Silicon versus the 6 MT required by conventional processes2, a 25% reduction,

iv. That it can do so at a lower cost advantage versus all traditional Silicon producers2.


Furthermore, once process improvement tests start (see point b above), HPQ will commence:

1. Using the Si produced for downstream testing and production of HPQ high-value-add products,

2. Providing samples to potential off-takers to allow for product customization,

3. Planning the deployment of commercial – scale production systems (PUREVAP™ QRR 4.0) capable of producing 2,500 tonnes per year of high purity silicon material.

“Some investors will question our need to allocate about a month to the PUREVAPTM GEN3 QRR pilot plant reactor startup, but they need to realize that the GEN3 is a scaled-up version of our GEN1 and GEN2 test platforms by a factor of about 200 (X). Starting up the reactor, on this “first-of-its-kind, state-of-the-art prototype,” requires more steps than just flipping on a switch. Our goal is to disrupt Silicon manufacturing; an industry that still relies on a conventional process developed back in the 1890s. Following our methodical approach, we are on the right path to validate our disruptive potential,” said Mr. Bernard Tourillon, President and CEO of HPQ Silicon Inc. “HPQ is the only company that will bring to market a new process for manufacturing Silicon that is perfectly suited to the new demands and realities of today’s Silicon market. With ESG principles playing an active role in materials sourcing and with recent geopolitical unrest emphasizing the need for stable trade partners and supply security, global corporations are becoming more aware of the difficulties in securing the ESG-compliant Silicon needed to meet their renewable energy agenda. The reality of chronic underinvestment in new technologies combined with the offshoring of Silicon production capacity, is creating massive opportunities for HPQ and its PUREVAPTM QRR patented process.”

About HPQ Silicon

HPQ Silicon Inc. (TSX-V: HPQ), is a Quebec-based innovative silicon solutions company that offers silica (SiO2) and 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, among other industries. On July 21, 2022, HPQ started trading as a Tier 1 Industrial Issuer on the TSX Venture Exchange.

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 PUREVAPTM “Quartz Reduction Reactors” (QRR), an innovative process (patent granted in the United States and pending in other jurisdictions), 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 PUREVAPTM 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 and nanowires of different sizes.

3. Through its second 100% owned subsidiary, HPQ Silica POLVERE Inc., HPQ is developing a new plasma-based process that allows a direct Quartz to Fumed silica transformation, removing the usage of hazardous chemicals in the making of Fumed silica and eliminating the Hydrogen Chloride Gas (HCI) associated with its manufacturing.

HPQ is also a technology development company interested in developing hydrogen-based ventures, that could be complementary to the QRR efforts. Currently, HPQ is evaluating two different approaches to reach this goal, those being:

1. Working with Swiss based company EBH2 Systems SAS on their proprietary process to manufacture Green Hydrogen via electrolysis, and

2. Developing HPQ’s own processes of making hydrogen via hydrolysis of nanosilicon materials made by our PUREVAPTM (NSiR).
