Management commentary

"IMPAQ's mandate is to broaden Zentek's audience among investment professionals across North America. Two things are worth their attention. Albany, our principal critical minerals asset, has been independently purified to 99.9992-per-cent purity at bench scale, consistent with published benchmarks for nuclear-grade graphite -- with a NI 43-101 preliminary economic assessment targeted for completion this summer. ZenGUARD, our patented graphene coating platform, is already generating commercial revenue. We selected IMPAQ in part because their outreach runs in both English and French. Quebec is a hub for graphite and graphene companies, and the investors who follow that sector should know Zentek's name," said Mohammed (Moe) Jiwan, chief executive officer of Zentek.

Peter Wood, PEng, PGeo, vice-president, development, of AGC, a qualified person under National Instrument 43-101, has reviewed and approved the technical information contained in this news release.

About Albany graphite

The Albany graphite project is an igneous-hosted graphite deposit located in Northern Ontario, held through the company's wholly owned subsidiary Albany Graphite Corp. Independent bench-scale testing conducted in collaboration with American Energy Technologies Company, as previously disclosed by the company on Sept. 22, 2025, confirmed ultrahigh purity of 99.9992 per cent with an equivalent boron concentration of 2.60 ppm (parts per million), meeting published benchmarks for potential nuclear-grade applications. The project is being advanced as a potential domestic North American source of critical-grade graphite for nuclear, battery and defence supply chains. Graphite is designated a critical mineral by both the government of Canada and the United States Department of Energy.
