Zentek Ltd. ("ZEN" or the "Company") (TSX-V:ZEN and OTC:ZENYF), a Canadian IP development and commercialization company focused on next-gen healthcare solutions, is pleased to announce that it has commenced receiving direct retail orders for ZENGuard™-enhanced surgical masks under its Medical Device Establishment License ("MDEL") recently issued by Health Canada, further to the Company's press release dated November 29, 2021.

As previously announced, the MDEL allows the Company to produce and sell its own Class I personal protective equipment ("PPE") products in Canada, which are coated with ZENGuard™ antimicrobial coating, in addition to supplying its Canadian partner Trebor Rx Corp. ("Trebor") with ZENGuard™ quantities for application on Trebor's products. The MDEL allows the Company to source and work with other manufacturers and distributors around the world in addition to Trebor to produce and sell directly Class I PPE products in the Canadian market.

Greg Fenton, CEO of ZEN, commented, "We believe this initial interest for ZENGuard™-enhanced surgical masks in the retail market highlights the importance the public continues to place on enhanced and innovative PPE products. The pandemic has greatly enhanced this trend and we expect our products to benefit from the heightened awareness of the importance of infection control not only in healthcare settings but by the general public as well."
