PUREVAP™ QRR Commissioning Completed

MONTREAL, May 26, 2022 -- HPQ Silicon Resources Inc. (“HPQ” or the “Company”) ( TSX-V: HPQ ) ( OTCQX: HPQFF ) ( FWB: UGE ), an innovative silicon solutions and technology development company, would like to report to shareholders that technology provider, PyroGenesis Canada Inc. ( TSX: PYR ) ( NASDAQ: PYR ) ( FRA: 8PY ), has informed HPQ that the commissioning phase of the program has been completed and that the PUREVAP TM Quartz Reduction Reactor ( QRR) pilot plant is now functional.

HPQ PUREVAP TM QRR PROJECT STARTING ITS MOST EXCITING PHASE
With the GEN3 PUREVAP TM QRR pilot plant functional the project is entering its final Research and Development phase; operating the pilot plant to test the system under operational conditions and producing high purity Silicon material sought after by battery makers and high value application manufacturers.

Budgeted at CDN$ 2,830,000 and lasting up to twelve (12) months, this final phase of the program will allow HPQ to validate and quantify the following PUREVAP TM QRR disruptive advantages identified during the previously completed Gen1 and Gen2 PUREVAP TM QRR testing phases:

As the test work advances, HPQ will commence:

1. Using the material for downstream testing and production of more HPQ high value add products,
2. Providing samples to potential off-takers to allow product customization, and
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.

“With the PUREVAP TM GEN3 QRR pilot plant functional, HPQ is ready to disrupt Silicon manufacturing, an industry that still relies on a traditional process developed in 1899 to make silicon. The PUREVAP TM QRR pilot plant could not have come online at a more opportune time. Demand for traditional silicon is estimated to exceed 3.8 million tonnes by 2025 3 . This represents an addressable market worth over US$ 10 billion based on historical average selling price for 5.5.3 Si (98.5% Si) of US$2,600 per Tonne 3 , or over US$ 38 billion based on the average spot price for 5.5.3 Si of US$10,000 per Tonne obtained during Q4 2021 and Q1 2022 4 . These numbers do not include demand that is about to come online for high purity silicon from the battery and high-performance material companies just as bottlenecks we had foreseen are now occurring in the silicon supply chain,” said Mr. Bernard Tourillon, President and CEO of HPQ Silicon. Mr. Tourillon further stated, “ With ESG principles playing an active role in materials sourcing, and recent geopolitical unrest emphasizing the need for stable trade partners and security of supply, the world is more aware of the difficulties in 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.”

About HPQ Silicon Resources
HPQ Silicon Resources Inc. ( TSX-V: HPQ ) is a Quebec-based innovative silicon solutions company that offers silica (SiO 2 ) 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 (SiO 2 ) 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 granted in the United States and pending in other jurisdictions), which will permit the one-step transformation of quartz (SiO 2 ) 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 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 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 EBH 2 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 ).

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.
