Last Component of HPQ GEN3 Quartz Reduction Reactor Has Shipped, Q4 Commissioning on Track

"Knowing that the power supply is finally on its way confirms that we are getting closer to the start the GEN3 PUREVAP^TM QRR, closer to making battery grade silicon (Si) and closer to validating the commercial potential of the PUREVAP^TM QRR process," said Bernard Tourillon, President and CEO of HPQ Silicon. "In addition to its traditional applications, silicon is just beginning its path to battery utilization. The addressable markets for our Silicon products are massive, diverse and with our pilot plant operational, we will be well positioned to start looking for additional downstream applications where our product can be of value."

About HPQ Silicon Resources
HPQ Silicon Resources Inc. (TSX-V: HPQ) is 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^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.

Disclaimers:
The Corporation's interest in developing the PUREVAP™ QRR and any projected capital or operating cost savings associated with its development should not be construed as being related to the establishing the economic viability or technical feasibility of any of the Company's Quartz Projects.
