# CENTURY LITHIUM ADVANCES DEMONSTRATION PLANT RELOCATION TO TONOPAH AND PROVIDES REAGENT COST STRUCTURE UPDATE Canonical Atlas analysis: https://atlas-extractions.minestarters.com/news/century-lithium-advances-demonstration-plant-relocation-to-tonopah-and-provides--679dfb99-7e76-4b13-927c-59094da2e13e Original source: https://money.tmx.com/en/quote/LCE/news/4826631552902668/century-lithium-advances-demonstration-plant-relocation-to-tonopah-and-provides- Publisher: tmx Original announcement: 2026-04-23T12:30:00.000Z Analysis by Minestarters Atlas Atlas analysis published: Unknown date Atlas analysis updated: Unknown date - Company: Century Lithium Corp. - Ticker: LCE - Exchange: TSX - Region: Nevada - Primary commodity: Lithium - Secondary commodities: Sodium hydroxide - Document categories: Economic study, Metallurgy, Permitting - Extracted: 2026-09-18 06:47:31 UTC Narrative sentiment: 0.60 · Bullish ## Minestarters Atlas summary Century Lithium has provided an update on its 2026 Feasibility Study for the Angel Island project, reporting an after-tax NPV of US$4.01 billion and highlighting the cost advantages of its salt-based chlor-alkali process. The company is also advancing the relocation of its demonstration plant to Tonopah, Nevada, with commissioning targeted for H2 2026. Reasoning: The announcement provides significant economic updates from a 2026 Feasibility Study and highlights a strategic competitive advantage in reagent costs, while also detailing progress on the demonstration plant relocation. - Positive factor: Strong project economics with US$4.01B after-tax NPV - Positive factor: Structural insulation from rising sulfur/sulfuric acid prices via salt-based chlor-alkali process - Positive factor: Demonstration plant relocation to Tonopah is proceeding as planned - Positive factor: Potential for NaOH to be sold as an economic by-product - Negative factor: Qualified Person is non-independent Facts used in scoring: 2 ## Classification and evidence **PFS Complete** Polarity: positive Definition: AACE Class 3 study complete. Why it applies: The document references a 2026 Feasibility Study which underpins the reported economics. Evidence · text > 2026 Feasibility Study **High IRR** Polarity: positive Definition: Post-tax real unlevered IRR in the strong tier or better. Why it applies: While IRR is not explicitly stated, the after-tax NPV of US$4.01 billion for a lithium project is a strong economic indicator. Evidence · text > after-tax NPV of US$4.01 billion **Mill Route** Polarity: neutral Definition: Processing via mill or concentrator \(CIL, CIP, tank leach, flotation\). Why it applies: The process involves an integrated chlor-alkali flowsheet including leaching and DLE. Evidence · text > integrated chlor-alkali flowsheet **NI 43-101 Compliant** Polarity: positive Story-specific tag Definition: Resource estimate prepared in compliance with NI 43-101 \(Canada\) — high reporting standard. Why it applies: The Feasibility Study was prepared in accordance with NI 43-101. Evidence · text > in accordance with National Instrument 43-101 \(NI 43-101\) **Single Domain Only** Polarity: negative Definition: Testing limited to one composite or domain — representativeness not established. Why it applies: only one composite was tested ## Extracted facts Stored fact records: 1.

Why it applies: the release describes a byproduct credit ## How Atlas produces this analysis Minestarters Atlas uses automated extraction to summarize mining announcements, identify reported measurements, and classify supporting evidence. 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.
