Minestarters Atlas analysis
Summary
NexMetals has reported successful Locked Cycle Test (LCT) results at the Selkirk Project in Botswana, confirming the ability to produce separate high-grade copper and nickel concentrates. The results show significant improvements in copper recovery and nickel concentrate grade compared to the 2024 Mineral Resource Estimate parameters.
Reasoning: The LCT results demonstrate a significant technical improvement over the parameters used in the 2024 MRE, specifically in copper recovery and nickel concentrate grade, while validating a new sequential flotation flowsheet.
Positive factors
- Improved copper recovery (81.3% vs 70.0% in 2024 MRE)
- Significant increase in nickel concentrate grade (10.9% vs 6.8% in 2024 MRE)
- Successful production of separate Cu and Ni concentrates
- Reduction in copper losses to tailings (11.4% vs 26.2%)
- Identification of additional payable metals (Ag, Co, PGEs)
Negative factors
- Nickel recovery (54.4%) is relatively low compared to copper
Facts used in scoring: 4
Classification and evidence
Mill Routeneutral
Processing via mill or concentrator (CIL, CIP, tank leach, flotation).
Why it applies: The results are from a flotation circuit (LCT) involving grinding and cleaning stages.
Evidence · text
“This new phase of flotation testwork”
QA/QC Disclosedpositive · Story-specific tag
Release includes QA/QC disclosure — certified lab, QP sign-off, or stated methods (blanks, standards, duplicates).
Why it applies: The release details specific QA/QC protocols including blanks, standards, and accredited laboratory oversight.
Evidence · text
“Commercially prepared blank samples and certified Cu/Ni sulphide analytical control standards are inserted in every batch”
Multi-Domain Testedpositive
Variability across ore domains (oxide, transition, fresh) has been addressed.
Why it applies: 2 distinct composites were tested

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.
