Minestarters Atlas analysis
Summary
West Cobar Metals has reported positive initial sizing test results at its Salazar project, where material finer than 38 micrometres concentrated 61% of the scandium in 51% of the mass while reducing iron content. The company is now proceeding with magnetic and gravity separation tests to further optimize the scandium flowsheet.
Reasoning: Initial metallurgical sizing tests demonstrate a clear pathway for scandium upgrading and iron reduction in the fine fraction.
Positive factors
- Initial sizing tests show successful concentration of scandium in fine fraction
- Reduction of iron impurity in the fine fraction
- Potential for improved feed grade to leaching
Negative factors
- Substantial scandium remains in coarser material
- Need to resolve balance between upgrading and retention
Facts used in scoring: 5
Classification and evidence
Bench Scale Onlynegative
Only preliminary bench tests completed — no locked-cycle or pilot work.
Why it applies: Initial sizing tests on a single indicative composite are preliminary screening-level work.
Evidence · text
“It comes from one indicative composite assembled from selected higher-grade drill intervals”
Inferred Resourcenegative
Speculative category — limited drilling, geological continuity assumed but not confirmed. Cannot support economic studies alone.
Why it applies: The reported resource is entirely in the Inferred category.
Evidence · text
“Salazar’s existing Inferred resource contains 15Mt”
Mill Routeneutral
Processing via mill or concentrator (CIL, CIP, tank leach, flotation).
Why it applies: the document describes a flotation route ("flotation")
Gravity Routeneutral
Gravity separation forms a material part of the flowsheet.
Why it applies: the document describes a gravity route ("gravity")
Single Domain Onlynegative
Testing limited to one composite or domain — representativeness not established.
Why it applies: only one composite was tested

Inferred Resourcenegative
Speculative category — limited drilling, geological continuity assumed but not confirmed. Cannot support economic studies alone.
Why it applies: category is "inferred"
Cut-off Undisclosednegative
High-grade interval reported without stating the cut-off grade used for compositing.
Why it applies: no cutoff_grade was stated
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

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.
