Minestarters Atlas analysis
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 factors
- High REE recovery (>97%) achieved
- Selectivity against lithium maintained
- Validates secondary-value opportunity from leach solutions
- QP sign-off included
Facts used in scoring: 2
Classification and evidence
High Recoverypositive
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 Routeneutral
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 Disclosedpositive · Story-specific tag
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 Onlynegative
Testing limited to one composite or domain — representativeness not established.
Why it applies: only one composite was tested

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.
