# CENTURY LITHIUM HIGHLIGHTS RARE EARTH POTENTIAL AT ANGEL ISLAND, NEVADA Canonical Atlas analysis: https://atlas-extractions.minestarters.com/news/century-lithium-highlights-rare-earth-potential-at-angel-island-nevada--78e0f5d6-ce70-45d1-9be1-87155d12c7f7 Original source: https://money.tmx.com/en/quote/LCE/news/7710152000168055/century-lithium-highlights-rare-earth-potential-at-angel-island-nevada Publisher: tmx Original announcement: 2025-12-11T13:30:00.000Z 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: Rare earth elements - Document categories: Metallurgy, Other - Extracted: 2026-09-18 07:03:52 UTC Narrative sentiment: 0.60 · Bullish ## Minestarters Atlas summary Century Lithium has demonstrated high recovery rates \(up to 99.9%\) for rare earth elements \(REEs\) from its Angel Island project in Nevada using ion-exchange technology. The test work, conducted on a 500-tonne bulk sample, shows that REEs enter solution under the same chloride leaching conditions used for lithium extraction. Reasoning: The release demonstrates high technical feasibility for REE recovery from a lithium project using existing chloride leaching, though economic viability remains unproven. - Positive factor: High REE recoveries \(up to 99.9%\) demonstrated via ion-exchange - Positive factor: REEs enter solution under existing lithium extraction conditions - Positive factor: QA/QC disclosed with independent accredited laboratory \(ALS\) - Positive factor: Strategic byproduct potential identified - Negative factor: Economic contribution not yet evaluated - Negative factor: Results based on a 500-tonne bulk sample, not the whole deposit Facts used in scoring: 7 ## Classification and evidence **High Recovery** Polarity: positive Definition: Recovery at or above the exceptional band for the commodity and processing route. Why it applies: REE recoveries via ion-exchange reached up to 99.9% Evidence · table > 99.9 % Context: 0.7 **QA/QC Disclosed** Polarity: positive Story-specific tag Definition: Release includes QA/QC disclosure — certified lab, QP sign-off, or stated methods \(blanks, standards, duplicates\). Why it applies: Release mentions duplicates, standards, and blanks provided by an accredited laboratory Evidence · text > Quality control in the form of duplicates, standards and blanks was provided by the laboratory. **Byproduct Commodity** Polarity: neutral Definition: The tested commodity is a byproduct rather than the primary economic driver. Why it applies: REEs are identified as a potential strategic byproduct to the primary lithium production Evidence · text > REEs to become a strategically important by-product alongside Angel Island's primary commodity, lithium carbonate **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: 7.

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.
