PyroGenesis Confirms Production of Fumed Silica at Pilot Scale Following Independent Analysis
MONTREAL, May 21, 2025 (GLOBE NEWSWIRE) -- PyroGenesis Inc. ('PyroGenesis') ( http://pyrogenesis.com ) (TSX: PYR) (OTCQX: PYRGF) (FRA: 8PY1), a high-tech company that designs, develops, manufactures and commercializes all-electric plasma processes and sustainable solutions to support heavy industry in their energy transition, emission reduction, commodity security, and waste remediation efforts, announces today further to its news release dated May 15, 2025, and today's press release from the Company's client HPQ Silicon Inc. ('HPQ'), independent analysis of material produced during the latest phase of system testing of the Fumed Silica Reactor (the 'FSR') is in fact fumed silica. PyroGenesis is engaged to develop the Fumed Silica Reactor by HPQ Silica Polvere Inc. ('Polvere'), a subsidiary of HPQ.
As previously announced, the new PyroGenesis designed FSR pilot plant has progressed through several important stages. After successfully proving out the underlying assumptions using lab scale tests, PyroGenesis is now testing the assumptions at pilot plant scale, with the current focus on validating equipment scale-up from lab to pilot plant scale and replicating the lab-scale fumed silica product quality.
PyroGenesis recently announced that (i) an important milestone of producing and collecting powder in the product recovery unit known as the 'baghouse' had been achieved, and (ii) samples had been sent to an independent laboratory to confirm that (a) the powder collected was fumed silica, and (b) what was collected was what was expected, and that any impurities that are observed were not only anticipated but are in a state that was expected and which can be removed.
The announcement today confirms that an independent analysis of the powder reflects that:
(1) the powder collected from the baghouse is in fact fumed silica,
(2) any impurities observed were not only anticipated but are in a state that was expected and which can be removed, and
(3) the amount produced was greater than anticipated and as such bodes well for the ultimate economics of the project.

In a side-by-side comparison, the PyroGenesis material appears well aligned with the microstructure and complexity of mid to high surface area of commercial grade fumed silica produced by Evonik Corporation, typically in the range of 150 to 200 m²/g.
The balance of the pilot plant program will now be focused on two primary objectives:
a) first, to focus on enhancing product purity by perfecting powder morphology and viscosity, and
b) second, to focus on delivering the production target goal of 50 tonnes per year (TPY).
In parallel, the FSR pilot plant will undergo a series of optimization tests, which aim to:
These efforts will provide invaluable information required for scale-up plans and equipment modifications required to make the system commercially viable. Together, the results of the characterization and optimization phases will essentially determine market fit.
'Today's announcement is a welcomed milestone which has increased the probability of success, but we must remember that until we have proven out every step, there is no guarantee that success will be the result,' said P. Peter Pascali, President and CEO of PyroGenesis, 'Having said that we are very pleased with the results of this analysis, as it confirms our theoretical expectations at a key juncture in the overall project.'
Fumed silica is one of the most widely used industrial materials, and can be found in thousands of products we use every day, including personal care, cosmetics, toothpaste, pet litter, powdered food, milkshakes, instant coffee, pharmaceuticals, agriculture (food & feed), adhesives, paints, inks, photocopy toner, sealants, fiber optic cables, thermal insulation, construction materials, and batteries, just to name a few. It is often used in these products as a thickening/anti-caking agent, used to stabilize and improve the texture and consistency of the end-product.
PyroGenesis' involvement in developing fumed silica from quartz is part of its three-vertical solution ecosystem that aligns with economic drivers that are key to global heavy industry. Fumed powders are part of PyroGenesis' Commodity Security and Optimization vertical, where the development of advanced material production techniques, and the use of technology such as plasma to recover viable metals, chemicals, and minerals from industrial waste, helps to maximize raw materials and improve the availability of critical minerals. The Company's other verticals are Energy Transition and Emission Reduction and Waste Remediation.

Koryx Copper Announces Filing of its Annual Information Form
VANCOUVER, British Columbia, June 06, 2025 (GLOBE NEWSWIRE) — Koryx Copper Inc. ('Koryx' or the 'Company') (TSX-V: KRY) is pleased to confirm the filing of its Annual Information Form ('AIF') for the year ended August 31, 2024 on SEDAR+ under the Company's profile at An electronic copy of the AIF may be obtained on the Company's website at or under the Company's SEDAR+ profile. About Koryx Copper Inc. Koryx Copper Inc. is a Canadian copper development Company focused on advancing the 100% owned Haib Copper Project in Namibia whilst also building a portfolio of copper exploration licenses in Zambia. Haib is a large, advanced (PEA-stage) copper/molybdenum porphyry deposit in southern Namibia with a long history of exploration and project development by multiple operators. More than 80,000m of drilling has been conducted at Haib since the 1970's with significant exploration programs led by companies including Falconbridge (1964), Rio Tinto (1975) and Teck (2014). Extensive metallurgical testing and various technical studies have also been completed at Haib to date. Additional studies are underway aiming to demonstrate Haib as a future long-life, low-cost, low-risk open pit, sulphide flotation copper project with the potential for additional copper production from heap leaching. Haib has a current mineral resource of 414Mt @ 0.35% Cu for 1,459Mt of contained copper in the Indicated category and 345Mt @ 0.33% Cu for 1136Mt of contained copper in the Inferred category (0.25% Cu cut-off). Mineralization at Haib is typical of a porphyry copper deposit and it is one of only a few examples of a Paleoproterozoic porphyry copper deposit in the world and one of only two in southern Africa (both in Namibia). Due to its age, the deposit has been subjected to multiple metamorphic and deformation events but still retains many of the classic mineralization and alteration features typical of these deposits. The mineralization is dominantly chalcopyrite with minor bornite and chalcocite present and only minor secondary copper minerals at surface due to the arid environment. Further details of the Haib Copper Project are available in the corresponding technical report titled, 'NI 43-101 Technical Report – August 2024 Mineral Resource Estimate for the Haib Copper Project, Namibia' dated effective August 31, 2024 (the 'Technical Report'). The Technical Report and other information is available on the Company's website at and under the Company's profile on SEDAR+ at ON BEHALF OF THE BOARD OF DIRECTORS 'Heye Daun' President, CEO and Director Additional information is also available by contacting the Company: Julia Becker Corporate Communications [email protected] +1-604-785-0850 Neither the TSX Venture Exchange nor its Regulation Services Provider (as that term is defined in the policies of the TSX Venture Exchange) accepts responsibility for the adequacy or accuracy of this release.
