HPQ Silicon Resources Inc. PUREVAP™ Quartz Reduction Reactor Update

"Labour shortages with certain suppliers were the cause of having to push back the commissioning from the end of Q1 to the start of Q2. However, with all the remaining commissioning steps to be done in-house, the testing phase should start within the coming weeks," said Mr. P. Peter Pascali, CEO and Chair of PyroGenesis. "Rest assured that the delays experienced to date are normal for a project of this type, and that this next milestone will complete the next step towards participating in a marketplace estimated by HPQ to be in excess of 3.8 million tonnes per year worth over US$10 Billion by 2025. We look forward to providing an update on progress within the next 3-4 weeks."

HPQ PUREVAP^TM QRR PILOT PLANT PROJECT ABOUT TO ENTER ITS MOST EXCITING R&D PHASE
With the GEN3 PUREVAP^TM QRR pilot plant functional shortly the project will be entering its final Research and Development phase, operating the pilot plant to tests the system under operational conditions and producing Silicon material sought after by battery makers and high value applications manufactures

Budgeted at CDN$ 2,830,000 and lasting up to twelve (12) months, this final phase of the program will allow the validation and quantification of the following PUREVAP^TM QRR disruptive advantages:

a) That it can produce a higher purity silicon material than any traditional processes in one step,
b) That it does not require the extremely pure feedstock needed by conventional processes,
c) That it only requires 4.5 MT of raw material to make 1 MT of Silicon versus the 6 MT required by conventional processes,
d) That it does possess a significant cash cost advantage versus the lowest cost traditional Silicon producer.

"In the coming weeks, when the PUREVAP^TM GEN3 QRR pilot plant is functional HPQ will be disrupting Silicon manufacturing, an industry that still relies on a traditional process to make silicon first developed in 1899. The start of the GEN3 PUREVAP^TM QRR pilot plant could not have come at a more opportune time. Demand for high purity silicon from the battery and high-performance material companies continues to rise just as bottlenecks we had foreseen are now occurring in the silicon supply chain. With ESG principles playing an active role in materials sourcing, the world is more aware of the difficulties of securing the ESG compliant Silicon needed to meet its renewable energy goals. The reality of chronic underinvestment in new technologies combined with the offshoring of Silicon production capacity, has created a massive opportunity for HPQ and its PUREVAP^TM QRR patented process. HPQ is the only company to bring to market a new process for making Silicon that is perfectly suited to the new demands and realities of the Silicon market," said Mr. Bernard Tourillon, President and CEO of HPQ Silicon.

About HPQ Silicon Resources
HPQ Silicon Resources 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.

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^TM "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^TM 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.
   

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 as it pertains to their proprietary process to manufacture Green Hydrogen via electrolysis, and
2. Developing our own processes of making hydrogen via hydrolysis of nanosilicon materials made by our PUREVAP^TM (NSiR).
