Zentek Ltd. ("Zentek" or the "Company") (NASDAQ:ZTEK; TSX-V:ZEN), an intellectual property development and commercialization company, is pleased to announce that McMaster University ("McMaster") has received two Natural Sciences and Engineering Research Council ("NSERC") Grants related to the aptamer-based rapid detection technology exclusively licensed by Zentek pursuant to its licence agreement dated April 11, 2021 with McMaster: The Alliance Missions Grant for the amount of $1,000,000, and an Idea to Innovation (I2I) Grant for the amount of $350,000 of which Zentek will make a $140,000 contribution. Both of these awards are the maximum awarded under each respective grant program, with disbursements delivered over the next two years.

"The research team at McMaster University has achieved significant milestones for the rapid diagnostic platform including the creation of a new ‘universal' aptamer with a high binding affinity to all known Covid variants," said Greg Fenton, CEO of Zentek. "Zentek is proud to continue working with the global-leading research team at McMaster University, with significant financial support from NSERC, which is a great endorsement of our technology and goal of commercialization."

Zentek will continue working with Dr. Yingfu Li and the research team at McMaster through in-kind contributions, using these grants towards commercializing its rapid diagnostic platform. The grants will be used to further commercialization efforts by improving the performance of aptamers, optimizing chip synthesis, and initiating additional tests that can be incorporated into its pathogen detection platform.
