Analysis by Minestarters Atlas
Minestarters Atlas analysis
Summary
Roscan Gold has announced a positive Preliminary Economic Assessment (PEA) for the Kandiolé Gold Project in Mali, reporting an after-tax NPV (5%) of US$498 million and an IRR of 43% at a US$3,100/oz gold price. The project is envisioned as a conventional open-pit operation with a 13-year mine life and an average annual production of ~93koz Au.
Reasoning: The announcement of a positive PEA with robust economics (43% IRR) and a significant Indicated resource provides a strong development pathway for the Kandiolé project.
Positive factors
- Strong economic metrics (43% IRR, US$498M NPV)
- High proportion of Indicated resource (97% of mill feed)
- Free-milling mineralization reported
- Robust sensitivity to gold price
Negative factors
- PEA level accuracy (±30%)
- Includes Inferred resources
Facts used in scoring: 3
Classification and evidence
Indicated Resourcepositive
Reasonable geological confidence based on adequate drilling; continuity can be assumed. Basis for Probable Reserves.
Why it applies: The resource estimate includes a significant 58.2 Mt Indicated component.
Evidence · text
“1.283 Moz Au indicated resource”
Inferred Resourcenegative
Speculative category — limited drilling, geological continuity assumed but not confirmed. Cannot support economic studies alone.
Why it applies: The estimate includes an Inferred component of 5.6 Mt.
Evidence · text
“0.09 Moz Au inferred resource”
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: Mr. Mark Kenwright, FAusIMM CP(Geo) is named as the Qualified Person.
Evidence · text
“reviewed and approved by Mr. Mark Kenwright, FAusIMM CP(Geo)”
Cut-off Disclosedpositive
Cut-off grade used for resource reporting is clearly stated, enabling like-for-like comparison.
Why it applies: Specific cut-off grades for Laterite, Saprolite, and Sap rock/Fresh rock are provided.
Evidence · text
“The applied cut-off grades are: 0.13 g/t Au (Laterite) 0.15 g/t Au (Saprolite) 0.20 g/t Au (Sap rock and Fresh rock)”

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.
