08:37 AM EDT, 07/03/2025 (MT Newswires) -- HPQ Silicon ( HPQFF ) , a technology company involved in innovation across advanced materials and critical process development, and trading near 52-week lows, on Thursday said that material analysis conducted by the leading global fumed silica manufacturer (LGFSM) confirmed several notable improvements in the fumed silica produced during Phase 1 Test #5 compared to Test #4.

Technology supplier, PyroGenesis ( PYRGF ) informed the company that, in addition to successfully replicating the production and collection of material in the dedicated product recovery unit, HPQ Silica Polvere's, a unit of the company, proprietary Fumed Silica Reactor (FSR) pilot plant operated under a semi-continuous feeding approach during the latest pilot test. According to LGFSM, Carbon-based impurities were reduced by 85%, other impurities were significantly lowered, with reductions ranging from 50% to 86% and material surface area increased by 57%.

"These results confirm that key material properties can be reliably reproduced and even improved at larger scale, establishing a solid foundation for future process optimization," said HPQ Silicon ( HPQFF ) and HPQ Silica Polvere Chief Executive Bernard Tourillon. "Having overcome the key technical challenges to reach this Phase 1 completion milestone, we believe the remaining steps-specifically achieving the targeted surface area range with the FSR-are now well within reach."

Shares of HPQ closed unchanged at $0.155 on Wednesday on the TSX Venture Exchange.
