# Zentek Files Technical Report for the Albany Graphite PEA: US$3.85 Billion After-Tax NPV at a 5% Discount Rate, 27.4% After-Tax IRR, on an Acid-Free Route to Ultra-High-Purity Graphite Canonical Atlas analysis: https://atlas-extractions.minestarters.com/news/zentek-files-technical-report-for-the-albany-graphite-pea-us-3-85-billion-after--ab961fe9-e4c4-4deb-9be3-d5cf80dff79b Original source: https://orestocks.com/company/ZEN.V/press-releases/6158244542695071 Publisher: orestocks Original announcement: 2026-09-24T11:40:00.000Z Analysis by Minestarters Atlas Atlas analysis published: Unknown date Atlas analysis updated: Unknown date - Company: Zentek Ltd. - Ticker: ZEN.V - Exchange: Unavailable - Region: Northern Ontario - Primary commodity: Graphite - Secondary commodities: None reported - Document categories: Economic study, Resource update, Metallurgy - Extracted: 2026-09-24 11:48:21 UTC Narrative sentiment: 0.70 · Bullish ## Minestarters Atlas summary Zentek has filed the technical report for its Albany Graphite Project Preliminary Economic Assessment \(PEA\), outlining a US$3.85 billion after-tax NPV at a 5% discount rate and a 27.4% after-tax IRR. The study proposes an acid-free purification route to produce 30,000 tonnes per year of ultra-high-purity graphite over a 30-year production period, with an initial capital cost of US$817 million. The project also features a significant mineral resource estimate, including 23.1 Mt indicated at 4.14% Cg and 13.3 Mt inferred at 2.88% Cg, and is recommended for advancement to a Pre-Feasibility Study. Reasoning: Zentek has filed a technical report for its Albany Graphite PEA, showing robust economics with a US$3.85 billion after-tax NPV and 27.4% IRR, based on an acid-free purification process for ultra-high-purity graphite. The study is preliminary and relies on bench-scale metallurgical results and includes a significant inferred resource component. The project has a substantial resource base and is recommended for advancement to a PFS. - Positive factor: Strong after-tax NPV and IRR for a PEA - Positive factor: Acid-free purification process for ultra-high-purity graphite - Positive factor: Significant indicated and inferred resource base - Positive factor: Recommendation to advance to PFS - Negative factor: PEA is preliminary in nature and includes inferred resources - Negative factor: Purification performance based on bench-scale testwork, not validated at commercial scale - Negative factor: Permitting is in early stages, no determination or application made - Negative factor: Operating cost per tonne of finished graphite products is high Low confidence — this extraction should be reviewed alongside the original source.

However, the unspecified recovery basis and bench-scale nature of the underlying testwork introduce uncertainty. - Positive factor: Good flotation recovery for graphite - Positive factor: Flotation circuit requires no lime or acid pH modifiers, indicating simpler processing - Negative factor: Recovery basis is unspecified - Negative factor: Performance based on bench-scale testwork, not validated at commercial scale #### Tags used in scoring **Mill Route** Polarity: neutral Definition: Processing via mill or concentrator \(CIL, CIP, tank leach, flotation\). Why it applies: The document refers to a flotation recovery and flotation circuit, indicating a mill-based processing route. Evidence · table > Flotation recovery \(%\) Context: Flotation recovery \(%\) **Bench Scale Only** Polarity: negative Definition: Only preliminary bench tests completed — no locked-cycle or pilot work. Why it applies: The purification performance and product specifications in the economic model are based on bench-scale testwork and have not yet been validated at continuous commercial scale or through customer qualification.

Sentiment reflects the extracted narrative and classification rules; it is an interpretation, not a reported measurement. Evidence quotes and context are provided where available. Missing data, low-confidence results, and review flags indicate limitations. Check the original publisher announcement before relying on an interpretation.
