ZEN Graphene Solutions Announces Initial Phase 2

Cytotoxicity Results for Its Graphene-Based Compound

Guelph, ON - February 4, 2021, ZEN Graphene Solutions Ltd. ("ZEN" or the "Company") (TSX-V:ZEN and OTC:ZENYF) is pleased to announce very promising initial phase 2 results of the 7-day repeated dose safety testing from Nucro Technics for potential human pharmaceutical use of its graphene-based compound.

Dr. Francis Dubé, ZEN Executive Chairman, commented: "The company continues to make positive progress towards our patent-pending, biocidal compound being considered as a pharmaceutical agent. Health safety evaluation in preclinical models is the most important consideration at this stage - and with the high dose (1,000 mg/kg) in this study being 20,000 times higher than the Minimum Inhibitory Concentration from the Mount Sinai study - we are incredibly encouraged. We will continue to move this new potential therapeutic towards Phase 1 human trials as quickly as possible pending the final report from Nucro-Technics ."

Initial Phase 2 Test Results Summary and Next Steps

In this repeated dose study, groups of three males and three females were dosed with either 50 mg/kg, 250 mg/kg, or 1,000 mg/kg of ZEN's patent- pending biocidal compound once per day for seven days.

ZEN's patent-pending biocidal compound was administered orally close to the throat area of the rats daily for 7 days at dose levels of 50 mg/kg, 250 mg/kg, or 1,000 mg/kg. Based on the clinical observations, food consumption, body weights, blood clinical pathology and post-mortem examination, there were no test article related findings of concern in any of the dose levels evaluated in this study. Tissues from the main organs are now being prepared for histopathology examination and these results will be included with the final report.

Pending final histopathology results, we are preparing to initiate a pivotal 14- day repeated dose toxicity safety study that will be conducted at Nucro- Technics Laboratories in accordance with Good Laboratory Practice regulation to support Phase 1 human clinical trials.
