The feedback validates both the Fumed Silica Reactor and its process, while also helping identify key optimizations to enhance material quality ahead of the next phase tests.
MONTREAL, Canada — HPQ Silicon Inc. (“HPQ” or the “Company”) (TSX-V: HPQ) (OTCQB: HPQFF) (FRA: 8PY1), a technology company driving innovation in advanced materials and critical process development, is pleased to inform shareholders that it has received results from testing conducted on the material shipped last week.
As announced in our May 28, 2025, release, a leading global fumed silica manufacturer (under the LOI) requested fumed silica material samples produced by HPQ Silica Polvere Inc.’s (HSPI) [1] proprietary Fumed Silica Reactor (FSR) pilot plant during the fourth “Phase One” batch test, and collected in the dedicated product recovery unit (commonly known as the “baghouse”).
Today, HPQ is proud to announce that the leading global fumed silica manufacturer has confirmed that the material tested—is indeed fumed silica. This new milestone represents another validation of the scalability of our FSR technology and the uniqueness of our one-step plasma-based process to produce fumed silica directly from quartz.
With HSPI’s technology supplier, PyroGenesis Inc. (TSX: PYR, OTCQX: PYRGF, FRA: 8PY1), now able to collect material produced by the FSR in the baghouse section—and with a leading global fumed silica manufacturer able to deliver comprehensive material analyses in approximately five business days (compared to the 30+ days typically required by university laboratories)—the critical feedback loop between testing, analysis, and process optimization has been significantly streamlined. This acceleration enhances HSPI’s ability to fine-tune its process and improve product quality to meet market specifications.
“Gaining direct access to the testing facilities of the world’s leading fumed silica manufacturer—an organization with more than 80 years of manufacturing and market expertise—is a rare and valuable opportunity,” said Bernard Tourillon, President and CEO of HPQ Silicon and HPQ Silica Polvere Inc. “It significantly accelerates our validation efforts for HSPI’s FSR technology and its ability to produce fumed silica that meets their rigorous specifications. With the milestones we’ve achieved in 2025 and our ongoing industry discussions, our confidence in the potential of this proprietary process to disrupt conventional production methods and address growing market demand continues to grow.”
