# CENTURY LITHIUM ACHIEVES HIGH RECOVERY OF RARE EARTH AND CRITICAL ELEMENTS FROM PRIMARY LEACH SOLUTIONS Canonical Atlas analysis: https://atlas-extractions.minestarters.com/news/century-lithium-achieves-high-recovery-of-rare-earth-and-critical-elements-from--0a2f7e79-4346-4b53-a338-c12e6a8da893 Original source: https://money.tmx.com/en/quote/LCE/news/5521941041123512/century-lithium-achieves-high-recovery-of-rare-earth-and-critical-elements-from- Publisher: tmx Original announcement: 2025-12-02T13:30:00.000Z 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, Scandium, Lanthanum, Cerium, Dysprosium, Gadolinium, Neodymium, Praseodymium, Cesium - Document categories: Metallurgy, Other - Extracted: 2026-09-18 07:04:11 UTC Narrative sentiment: 0.80 · Bullish ## Minestarters Atlas summary Century Lithium reported successful ion-exchange test work at its Angel Island project in Nevada, achieving over 97% recovery of rare earth elements and critical metals from lithium leach solutions. The testing demonstrated high selectivity, allowing for REE recovery without impacting the primary lithium extraction process. Reasoning: The announcement reports successful ion-exchange test work achieving high recovery of REEs and critical metals from lithium leach solutions without compromising lithium recovery, representing a significant technical milestone for the Angel Island project. - Positive factor: High REE recovery \(>97%\) achieved - Positive factor: Selectivity against lithium maintained - Positive factor: Validates secondary-value opportunity from leach solutions - Positive factor: QP sign-off included Facts used in scoring: 2 ## Classification and evidence **High Recovery** Polarity: positive Definition: Recovery at or above the exceptional band for the commodity and processing route. Why it applies: Ion-exchange test work achieved greater than 97% recovery of identified REEs and critical metals. Evidence · text > Ion-exchange test work achieved greater than 97% recovery of the identified REEs and critical metals **Mill Route** Polarity: neutral Definition: Processing via mill or concentrator \(CIL, CIP, tank leach, flotation\). Why it applies: The process involves ultrafiltration, direct lithium extraction \(DLE\), and subsequent steps. Evidence · text > process flowsheet, which includes ultrafiltration, direct lithium extraction \("DLE"\) and subsequent steps **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: The release includes a Qualified Person \(Todd Fayram, MMSA-QP\) sign-off. Evidence · text > Qualified Person Todd Fayram , MMSA-QP and Senior Vice President, Metallurgy of Century Lithium is the qualified person as defined by National Instrument 43-101 and has approved the technical information in this release. **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: 2.

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.
