Zentek Ltd.

Zentek Ltd. announced the launch of its direct-to-consumer sales channel for its ZenGUARD™ air filters and masks via the website zenguard.com. This new channel complements the company's existing government and institutional sales. ZenGUARD™ is a Canadian-developed, patented graphene-based filter coating that has received support from the Government of Canada, including validation and purchase orders. Independent lab tests show ZenGUARD™-coated filters capture significantly more viruses than uncoated filters, with no detectable coating release.

Zentek Ltd. announced several corporate updates, including receiving its first orders under a Government of Canada standing offer for its ZenGUARD™ Enhanced Air Filters. Additionally, research coverage has been initiated by Atrium Research Corporation. The company also reported successful bench-scale purification of Albany graphite, achieving a maximum purity of 99.99985 wt.% carbon (5N+), which supports the premium product specifications incorporated into the Preliminary Economic Assessment (PEA) for the Albany Graphite Project. The PEA projects an after-tax net present value of US$3.85 billion.
