Analysis by Minestarters Atlas
Minestarters Atlas analysis
Summary
Resouro Strategic Metals Inc. has completed a Preliminary Economic Assessment (PEA) for its Tiros Project in Brazil, projecting an after-tax NPV of US$714.9 million and an IRR of 44.2%. The starter operation targets a high-grade 9.5Mt ROM feed with 26.3% TiO2 and 10,832 ppm TREO using an open-pit mining method.
Reasoning: The completion of a PEA for the Tiros project demonstrates robust economics with high IRR and NPV, though it relies on Inferred resources for the starter operation.
Positive factors
- Strong NPV of US$714.9 million
- High IRR of 44.2%
- High-grade starter operation (26.3% TiO2)
- Large existing M&I resource base (1.4 billion tonnes)
- Favourable jurisdiction (Minas Gerais, Brazil)
Negative factors
- Economics based on Inferred resources
- Titanium recovery is relatively low at 68.7%
- Rare earth recovery is 67%
Facts used in scoring: 4
Classification and evidence
PEA Onlyneutral
Only Class 4 / Initial Assessment economics available. Not bankable.
Why it applies: The document explicitly states it is a Preliminary Economic Assessment and not a feasibility study.
Evidence · text
“The PEA is preliminary in nature.”
Inferred Heavy Feednegative
Material Inferred share of LOM mill feed, or the share is undisclosed.
Why it applies: The starter operation contemplates processing high-grade material that is part of the broader resource, but the PEA includes Inferred Mineral Resources.
Evidence · text
“It includes Inferred Mineral Resources that are considered too speculative geologically to have the economic considerations applied to them”
High IRRpositive
Post-tax real unlevered IRR in the strong tier or better.
Why it applies: The reported after-tax IRR of 44.2% is in the exceptional tier.
Evidence · text
“after-tax internal rate of return (IRR) of 44.2%”
NI 43-101 Compliantpositive
Resource estimate prepared in compliance with NI 43-101 (Canada) — high reporting standard.
Why it applies: The PEA was prepared according to NI 43-101 standards.
Evidence · text
“prepared by a team led by Norda Stelo according to National Instrument 43-101 Standards”

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
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
No Contained Metalnegative
Tonnage and grade reported but contained metal not calculated or disclosed — incomplete reporting.
Why it applies: contained_metal was not reported
No QP/CP Disclosurenegative
No Qualified Person or Competent Person named — lower credibility for the estimate. A QP/CP should be a member of a recognized professional association with relevant experience.
Why it applies: no Qualified or Competent Person is named anywhere in the release
PEA-Supportingneutral
Resource estimate prepared to support a Preliminary Economic Assessment — early-stage study.
Why it applies: the release names the study this estimate supports
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.
