Summary
Century Lithium has filed a Feasibility Study for its 100%-owned Angel Island Lithium Project in Nevada. The study reports an after-tax NPV of $4.01 billion and an IRR of 27.4%, supported by Proven and Probable reserves and a projected mine life of over 60 years.
Reasoning: The announcement of a Feasibility Study for a large-scale lithium project with high IRR and significant NPV, supported by pilot plant validation, represents a major project milestone.
Positive factors
- Strong after-tax NPV of $4.01 billion
- High IRR of 27.4%
- Very long mine life exceeding 60 years
- Proven and Probable reserves established
- Integrated processing with co-product credits (sodium hydroxide) potentially reducing net OPEX to below zero
Facts used in scoring: 3
Classification and evidence
PFS Completepositive
AACE Class 3 study complete.
Why it applies: The document announces a Feasibility Study (FS), which is a higher level of maturity than PFS, but fits the engineering maturity described.
Evidence · text
“FEASIBILITY STUDY OF THE CLAYTON VALLEY LITHIUM PROJECT”
High IRRpositive
Post-tax real unlevered IRR in the strong tier or better.
Why it applies: The reported after-tax IRR of 27.4% is in the strong tier for a lithium development project.
Evidence · text
“after-tax cash flow has a 27.4% Internal Rate of Return ("IRR")”
Long Reserve Lifepositive
Reserve life index in the top tier of the single ladder.
Why it applies: The project supports a mine life exceeding 60 years, which is in the top tier.
Evidence · text
“supporting a mine life exceeding 60 years”
NI 43-101 Compliantpositive
Resource estimate prepared in compliance with NI 43-101 (Canada) — high reporting standard.
Why it applies: The report was prepared in accordance with NI 43-101.
Evidence · text
“prepared in accordance with National Instrument 43-101 (NI 43-101)”

Reasoning: Significant lithium resource and reserve reported.
Positive factors
- Large scale resource
Evidence · text
“Measured and Indicated Mineral Resources of 1.138 billion t at 966 parts per million ("ppm") lithium, containing 5.852 million t lithium carbonate equivalent ("LCE")”
Tags used in scoring
Indicated Resourcepositive
Reasonable geological confidence based on adequate drilling; continuity can be assumed. Basis for Probable Reserves.
Why it applies: category is "indicated"
Cut-off Undisclosednegative
High-grade interval reported without stating the cut-off grade used for compositing.
Why it applies: no cutoff_grade was stated
QP/CP Signedpositive
Qualified Person (QP) or Competent Person (CP) named and signed off — a member of a recognized professional association (e.g., AusIMM, SME, AIG, P.Geo) with relevant experience.
Why it applies: qp_signed is true
NI 43-101 Compliantpositive
Resource estimate prepared in compliance with NI 43-101 (Canada) — high reporting standard.
Why it applies: reporting_standards includes ni_43_101
DFS-Supportingneutral
Resource estimate prepared to support a Definitive Feasibility Study — requires high M&I confidence.
Why it applies: the release names the study this estimate supports

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.
