HPQ Silicon Resources Sources Raw Material Needed for Purevap™ Quartz Reduction Reactor Operations

MONTREAL, Dec. 21, 2021 - HPQ Silicon Resources Inc. ("HPQ" or the "Company") (TSX-V: HPQ) (OTCQX: HPQFF) (FWB: UGE), an innovative silicon solutions and technology development company, is pleased to inform shareholders that it has secured, with a Quebec-based supplier, the procurement, and January 2022 delivery, of the high purity quartz material needed to operate the GEN3 PUREVAP^TM Quartz Reduction Reactor ("QRR") Pilot Plant. HPQ is also please to inform shareholders that technology provider, PyroGenesis Canada Inc. (TSX: PYR) (NASDAQ: PYR) (FRA: 8PY), has informed HPQ that, taken into consideration the latest delays related to COVID-19 restriction implemented by the Quebec Government, the commissioning of the GEN3 PUREVAP^TM QRR will be completed during Q1 2022, and that shortly after that the pilot plant will be operational.

ONE STEP CLOSER TO VALIDATING PUREVAP^TM QRR GAME CHANGING ADVANTAGES
The PUREVAP^TM QRR is an innovative process, which permits the one-step transformation of quartz (SiO₂) into high purity silicon metal (from 99.5% to 99.99% Si) at reduced costs, energy input, and carbon footprint. This game changing advantage means that the PUREVAP^TM QRR process not only produces a higher purity silicon material than traditional processes, but it does not require the extremely pure feedstock needed by conventional processes. In fact, the process only requires 4.5 MT of raw material to make 1 MT of Silicon, versus the 6 MT required by conventional processes, a 25% reduction which potentially allows a 20% cash cost advantage versus the lowest cost traditional Silicon producer¹.

Si MARKET IN DEFICIT, PRICES SOARING, NEW GREENFIELD DEVELOPMENTS NEEDED²
Recent market events are focussing attention on the fact that Silicon (Si), also known as silicon metal, is one of today's key strategic energy metals needed to meet the goal of decarbonizing the economy by 2050. High Purity Silicon (2N+) is in very high demand due to the underlying needs for Silicon as feedstock for Polysilicon (Solar and Electronics), the emerging Batteries sectors, and the more typical industrial Silicone applications, at a time when capacity is simply not available to meet demand.

"HPQ has been at the forefront of Low-Cost Green Silicon innovation developments since 2015, and the up and coming start of the GEN3 PUREVAP^TMQRR pilot plant, could not be occurring at a more opportune time, as demand continues to rise and 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 difficulty 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, as we are the only company to bring to market a new process to make 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 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.
   

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).

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.
