Zentek Ltd SEC Filings

Zentek Ltd. closed a fully subscribed brokered LIFE private placement for gross proceeds of C$18,000,000. The company issued 18,000,000 units at C$1.00 per unit, each unit containing one common share and one warrant exercisable at C$1.50 until May 27, 2029.

Zentek plans to use net proceeds to advance the Albany Graphite Project, including a new Preliminary Economic Assessment, further ZenGUARD™ commercialization, payment obligations, and general working capital. Insiders purchased 695,000 units, and Red Cloud received C$1,197,360 plus 1,197,360 broker warrants at the offering price, with the offering still requiring final TSX Venture Exchange approval.

Zentek Ltd. reports that its ZenGUARD™ Enhanced Air Filters have been added to Innovative Solutions Canada’s Pathway to Commercialization source list. This makes Zentek an exclusive supplier of this type of innovation to the Government of Canada for a three-year period, allowing any federal department or agency to buy the filters directly.

The technology was validated by the National Research Council in a simulated classroom, where ZenGUARD™ increased the viral filtration efficiency of a standard MERV 8 filter by about fivefold in a single air exchange without measurable impact on airflow or energy use. The filters aim to deliver safer indoor air, lower HVAC energy consumption and emissions, longer service intervals, and less landfill waste, aligning with the federal Greening Government Strategy’s emissions reduction and waste diversion goals.

Zentek Ltd. received a revised classification from Health Canada’s Pesticides Regulatory Directorate confirming that its ZenGUARD™ Enhanced Air Filters are not regulated under the Pest Control Products Act because they operate through a mechanical mode of action. This conditional classification resolves the Canadian regulatory question previously highlighted in February 2026.

With this decision, Zentek is now accepting Canadian commercial orders for ZenGUARD™ Enhanced Air Filters and pursuing additional commercialization routes, including federal procurement, licensing, and sales of ZenGUARD™-coated filter media to HVAC supply‑chain participants. ZenGUARD™ uses a patented graphene-based coating, independently validated to deliver MERV 9 filtration under ASHRAE 52.2 with pressure drop comparable to uncoated filters, and is protected in Canada by a patent granted in 2022 with a term to 2041.

Zentek Ltd. is advancing its Albany Graphite Project by launching the 2026 environmental and social baseline program through its subsidiary Albany Graphite Corp., using ERM Consultants Canada and closely involving Constance Lake First Nation in all field campaigns.

The program continues baseline work started in 2019 and runs in parallel with technical and commercial studies feeding a Preliminary Economic Assessment targeted for completion in Summer 2026. Albany has demonstrated ultra-high-purity 5N+ graphite at 99.9992 wt.% Cg from project feedstock, positioning it for potential nuclear, battery, and defence supply chains.

Zentek Ltd. reports that its wholly owned subsidiary Albany Graphite Corp. has engaged independent economic consultancy AppEco Inc. to conduct a comprehensive market research and economic analysis for the Albany graphite project in Northern Ontario. The work covers four areas: an independent price grid by purity grade for nuclear, defense, battery and industrial markets; quantification of addressable demand in North America and allied nations; assessment of Albany’s competitive positioning versus other Western graphite projects, including synthetic substitution risk; and valuation of potential by-product credits from 18 critical minerals recoverable from the fluidized-bed reactor off-gas. Management explains that these independent data are intended to support a preliminary economic evaluation under Instrument national 43-101 and complement engineering work by Micon. Zentek reiterates prior lab results showing Albany graphite achieving 5N+ purity and properties suitable for potential nuclear and battery applications, positioning the project as a potential North American source of critical graphite.

Zentek Ltd., through its subsidiary Albany Graphite Corp., has signed an agreement with American Energy Technologies Co. to supply certified ultra-high-purity graphite samples and process-engineering inputs for the Preliminary Economic Assessment of the Albany Graphite Project being prepared by Micon International.

AETC will produce 4N, 4N+, and 5N+ graphite samples from Albany flotation concentrate with Certificates of Analysis and design a conceptual chlorine-free purification facility targeting 30,000 metric tonnes per year of feedstock. Three independent workstreams—Micon on engineering and economics, AppEco on market pricing, and AETC on process design and certified product—are now active, with key deliverables and the PEA targeted for completion in summer 2026.

Zentek Ltd. reports that its wholly owned subsidiary, Albany Graphite Corp., has engaged AppEco Inc. to complete an independent market research and economic analysis for the Albany Graphite Project in Ontario. The study will develop grade-specific price forecasts, quantify North American and allied-nation demand, analyze Albany’s competitive position, and assess potential value from 18 critical-mineral co-products produced by its electrothermal fluidized bed reactor process.

AppEco’s work is intended to provide independent market data to support a NI 43-101 compliant preliminary economic assessment that engineering firm Micon is preparing. Zentek expects to share workstream findings and anticipates publishing the PEA in the summer.

Zentek Ltd. reported that its subsidiary Triera Biosciences has completed a Government of Canada Innovative Solutions Canada contract focused on an aptamer-based asset to bind and deactivate H5N1 avian influenza. Triera selected a lead aptamer in about seven weeks, highlighting the platform’s speed versus conventional antibody approaches.

On the strength of this work, Triera executed an Ontario Centres of Innovation Collaborate 2 Commercialize agreement to fund development of proprietary seasonal influenza treatment candidates. The OCI C2C project budget is about $300,000, with matched cash contributions from OCI and Zentek, and will target common seasonal influenza A subtypes in collaboration with McMaster University.

Zentek Ltd. reports that its wholly owned subsidiary Albany Graphite Corp. has engaged Micon International to complete a new Preliminary Economic Assessment (PEA) for the Albany Graphite Project in Northern Ontario, with completion expected this summer. The study will incorporate an updated Mineral Resource Estimate and evaluate a thermal purification process that has produced 5N+ graphite at 99.9992 wt.% Cg directly from 86% Cg flotation concentrate using an electrothermal fluidized bed reactor without chlorine.

The PEA will cover mining methods, pit design, production scheduling, process flowsheet, capital and operating cost estimates, environmental and social considerations, and economic and sensitivity analysis under NI 43-101. The current Mineral Resource Estimate, effective April 30, 2023, reports Indicated Mineral Resources of 22.9 million tonnes grading 4.07% graphitic carbon (Cg) and Inferred Mineral Resources of 13.1 million tonnes grading 2.87% Cg, using cut-off grades of 1.22% Cg for open pit and 1.76% Cg for underground resources.
