HPQ SILICA POLVERE INC. SIGNS NON-DISCLOSURE AGREEMENT WITH LEADING FUMED SILICA MANUFACTURER

HPQ Silicon Inc. has noted a significant development with its fumed silica initiative.

HPQ's wholly owned subsidiary, HPQ Silica Polvere Inc. (HPQ Polvere), and technology provider PyroGenesis Canada Inc., have successfully signed a non-disclosure agreement (NDA) with a leading fumed silica manufacturer (LFSM). In order to maintain confidentiality for industry competitive reasons, the identity of the LFSM will remain undisclosed.

"The early interest expressed by a leading fumed silica manufacturer is a testament to our progress and the value of our efforts," said Bernard Tourillon, president and chief executive officer of HPQ Silicon and HPQ Polvere. "It validates our strategic decision to enter this sector, and we are proud to participate in this unique opportunity."

Purpose of the NDA

The main objective of the NDA is to allow the parties involved to assess the characteristics of fumed silica material produced by the HPQ Polvere fumed silica reactor in comparison with commercially available fumed silica and pyrogenic silica manufactured by the LFSM. The evaluation process will commence with submission of samples produced from the five remaining fumed silica reactor lab-scale tests, followed by a subsequent delivery of more samples produced by the pilot plant.

"It's important to caution investors that while this NDA indicates interest in our distinctive process, we are still in the early stages, and commercial success is not a guarantee," added Mr. Tourillon. "Nonetheless, it highlights the potential for exciting advancements in the fumed silica industry by HPQ Polvere."

About HPQ Silicon Inc.

HPQ Silicon is a Quebec-based TSX Venture Exchange Tier 1 industrial issuer. HPQ is developing, with the support of world-class technology partners PyroGenesis Canada and Novacium SAS, new green processes crucial to make the critical materials needed to reach net-zero emissions. HPQ activities are centred around the following five pillars:

1. Becoming a green low-cost (capex (capital expenditures) and opex (operating expenditures)) producer of high-purity silicon (2N+ to 4N) using its proprietary Purevap quartz reduction reactors (QRRs) being developed by PyroGenesis;
2. Becoming North America's first producer of micron-size high-purity silicon (3N and 4N) powders with the assistance of Novacium;
3. Working to become the first producer of nanosilicon materials from high-purity silicon chunks using the company's proprietary Purevap nanosilicon reactor (NSiR) being developed by PyroGenesis;
4. Becoming a green low-cost (capex and opex) producer of fumed silica using the company's proprietary fumed silica reactor being developed by PyroGenesis;
5. Developing a small and compact process for the on-demand production of hydrogen through hydrolysis of silicon and other materials.
