The PEA demonstrates robust economics at assumed ultra-high-purity graphite prices, but the project remains at a conceptual stage with significant de-risking required. Key milestones to watch: (1) successful scale-up of the fluidized bed reactor purification from bench to continuous commercial operation, (2) execution of offtake agreements or customer qualification contracts, and (3) completion of the Pre-Feasibility Study recommended by Micon. The absence of any sales contracts or product pricing agreements means the revenue assumptions are entirely unvalidated.

Executive Summary
Zentek Ltd. filed a NI 43-101 Preliminary Economic Assessment (PEA) for its wholly-owned Albany Graphite Project in Northern Ontario, prepared by Micon International. The PEA outlines an integrated open-pit mine, flotation concentrator, and acid-free thermal purification facility, reporting an after-tax NPV of US$3.85 billion at a 5% discount rate and a 27.4% after-tax IRR. The project carries significant execution risk as the purification process has only been demonstrated at bench scale, no offtake agreements exist, and the weighted average product price of US$23,485/t is based on projected ultra-high-purity graphite markets rather than confirmed contracts.
Key Facts
- After-tax NPV of US$3.85 billion at 5% discount rate and after-tax IRR of 27.4%
- Initial capital cost estimated at US$817 million with a 4.4-year after-tax payback period
- Total Indicated Mineral Resource of 23.1 Mt at 4.14% Cg; Total Inferred of 13.3 Mt at 2.88% Cg
- 30-year mine life processing 25.9 Mt of mill feed at 3.87% Cg, producing 30,000 t/a of finished ultra-high-purity graphite products
- Bench-scale thermal purification achieved up to 99.99985 wt.% carbon purity; commercial scale-up not yet validated
- No offtake agreements, customer contracts, or agreed product prices in place
- Weighted average realized product price of US$23,485/t held constant in real terms over project life
- Micon recommends advancing the project to a Pre-Feasibility Study with a budget of US$10.4 million
Financial Impact
After-tax NPV of US$3.85 billion at 5% discount rate; after-tax IRR of 27.4%; initial capital US$817 million; life-of-project operating costs US$6.67 billion; gross life-of-project revenue estimated at US$19.54 billion
Risk Factors
- Thermal purification process has only been demonstrated at bench scale; commercial-scale continuous operation, product purity, and throughput are unproven
- No offtake agreements, customer contracts, or agreed product prices exist; revenue assumptions are entirely projected
- Weighted average product price of US$23,485/t is highly dependent on successful qualification for nuclear, defence, and aerospace markets
- Capital cost estimate is AACE Class 5 with approximately 50% accuracy range; actual costs may vary materially
- Project is at exploration stage with no mining leases, permits, or environmental approvals obtained
- Inferred mineral resources (13.3 Mt) are considered too speculative for economic consideration and may not convert to reserves
