Minestarters Atlas analysis
Summary
Roscan Gold has announced a positive Preliminary Economic Assessment (PEA) for the Kandiolé Gold Project in Mali, reporting a base case after-tax NPV (5%) of US$498 million and an IRR of 43%. The project features an ~13-year mine life with an average annual production of approximately 92,786 oz of gold and an AISC of US$1,568/oz.
Reasoning: The announcement of a positive PEA with robust economics and a high-confidence resource base (97% Indicated) is a significant development for a junior explorer.
Positive factors
- Strong base case economics (43% IRR, US$498M NPV)
- High sensitivity to gold price (85% IRR at spot)
- High proportion of Indicated resource (97% of mill feed)
- Free-milling mineralization noted
Negative factors
- PEA level accuracy (±30%)
- Inclusion of Inferred resources in the economic model
- Project is in Mali (Tier-3 jurisdiction)
Facts used in scoring: 3
Classification and evidence
PEA Onlyneutral
Only Class 4 / Initial Assessment economics available. Not bankable.
Why it applies: The announcement is for a Preliminary Economic Assessment (PEA).
Evidence · text
“Preliminary Economic Assessment (the "PEA" or "Study")”
Indicated Resourcepositive
Reasonable geological confidence based on adequate drilling; continuity can be assumed. Basis for Probable Reserves.
Why it applies: The project contains a significant Indicated resource 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 project includes an Inferred resource component.
Evidence · text
“0.09 Moz Au inferred resource”
Free Millingpositive · Story-specific tag
Simple, clean ore amenable to standard processing without oxidation.
Why it applies: Metallurgical test work indicates predominantly free-milling mineralization.
Evidence · text
“mineralization is predominantly free-milling”
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: Mark Kenwright, FAusIMM CP(Geo) is named as the Qualified Person.
Evidence · text
“approved by Mr. Mark Kenwright, FAusIMM CP(Geo)”
Resource Updateneutral
Revised estimate for an existing resource — compare to prior to assess progress.
Why it applies: The source explicitly discloses a revised resource estimate
Evidence · text
“updated mineral resource estimate”

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.
