- Pilot-Scale Production Achieves Core Specifications Supporting Proposed Joint Venture
MONTREAL, Canada — HPQ Silicon Inc. (“HPQ” or the “Company”) (TSX-V: HPQ) (OTCQB: HPQFF) (FRA: 8PY1), a technology company specializing in advanced materials innovation and the development of next-generation processes, , announces that its subsidiary, HPQ Silica Polvere Inc. (“HSPI”) [2], has received a first purchase order for 50 kilograms of fumed silica from the strategic industrial partner previously disclosed on February 12, 2026.
The material was produced by HSPI’s technology supplier, PyroGenesis Inc., utilizing the Fumed Silica Reactor (“FSR”) pilot plant. The product is currently being prepared for delivery to the customer for advanced qualification testing.
To fulfill the order, the FSR was operated in semi-continuous mode for extended production runs beyond prior test campaigns. These longer-duration operations generated critical process and engineering data that will support scale-up modeling and commercial design parameters for the proposed 1,000 tonne-per-year facility contemplated under the previously announced non-binding memorandum of understanding (the “MOU”).
“This first purchase order marks an important operational milestone,” said Bernard Tourillon, Chairman, President and CEO of HPQ Silicon Inc. and HPQ Silica Polvere Inc. “It demonstrates that our pilot plant is transitioning from technical validation toward commercial engagement. Equally important, the extended production runs are providing the engineering data required to responsibly design and de-risk the proposed commercial-scale facility.”
Technical Validation Supports Commercial Progression
Progress toward final agreements under the MOU remains subject to the successful completion of third-party testing and validation of fumed silica produced by the FSR pilot plant.
HSPI confirms that it has received results from production samples previously manufactured and analyzed by an independent specialty laboratory in the United States [2]. The testing evaluated chemical composition and material characteristics relevant to the targeted commercial applications and confirmed that the material meets the fundamental specifications required to advance the project.
The combination of independent laboratory validation and the recent 50 kg purchase order for advanced customer testing indicates that fumed silica produced using the FSR has achieved defined chemical and compositional benchmarks necessary to support continued commercial development efforts.
Industry Context
Fumed silica is a high-value industrial material used across cosmetics, pharmaceuticals, food products, paints, coatings, sealants, adhesives, and construction materials. Its function as a thickening, anti-caking, rheology-modifying, and reinforcing agent makes it critical to performance and product consistency in large-volume global markets.
Conventional production methods typically rely on energy-intensive processes and centralized large-scale facilities. The FSR technology seeks to provide an alternative plasma-based approach using quartz (SiO₂) as feedstock, with the objective of reducing process complexity and eliminating the need for hazardous chemical intermediates.
“The ability to operate the FSR in extended semi-continuous mode while meeting core material specifications reinforces the engineering viability of this plasma-based approach,” P. Peter Pascali, President and CEO of PyroGenesis Inc., commented on the development. “Our objective has always been to demonstrate that fumed silica can be produced in a more energy-efficient and modular manner. These production runs represent another step in validating that the process can support commercial deployment parameters.”
Next Steps Toward Commercialization
The formation of the joint venture contemplated under the MOU remains subject to the negotiation and execution of definitive agreements governing the rights and obligations of the parties. The parties currently anticipate completing such agreements by the end of Q2 2026; however, there can be no assurance that a joint venture will be formed, that definitive agreements will be executed within the anticipated timeframe, or that any resulting joint venture will be commercially viable.
“We are advancing methodically,” added Mr. Tourillon. “Independent validation, extended pilot production, and customer qualification testing are all required steps before commercial commitments are finalized. Our focus remains on aligning technical performance, engineering scalability, and market demand before moving to definitive agreements.”

About HSPI the Fumed Silica Reactor (FSR)
As HSPI Technological supplier, PyroGenesis is the exclusive supplier of a plasma-based technology that uses quartz (SiO2) as a raw material to produce commercial-grade fumed silica in a single and eco-friendly process while eliminating the use of harmful chemicals generated by some conventional methods. The FSR requires no additional processes to develop and prepare feedstock, and no intermediary toxic chemical-based processing. The FSR can produce fumed silica from quartz at one physical location.
When compared to some multi-step, traditional processing methods,the expected benefits of our fumed silica reactor process can generally be summarized as follows:
(1) Lower capital costs
(2) Lower operating costs
(3) Reduction of CO2 emissions
(4) Reduction in energy footprint
(5) Elimination of purchase and storage requirements for hazardous chemicals
(6) Simplified logistics/shortened production chain due to the single location, single system, single phase process, and the elimination of feedstock ingredient handling, storage, preparation/transformation, and transportation
(7) Safer production environment due to absence of dangerous, toxic, or explosive chemicals
HPQ Silicon is a Quebec-based TSX Venture Exchange Tier 1 Industrial Issuer. With the support of world-class technology partners PyroGenesis Canada and NOVACIUM SAS, the company is developing new green processes crucial to make the critical materials needed to reach net zero emissions.
