Summary
Andina Copper reported significant drill results from the Cobrasco porphyry copper-molybdenum discovery in Colombia. Hole CDH011 intersected a 400m wide interval at 0.46% Cu, including a high-grade 206m zone at 0.67% Cu, confirming vertical continuity of the system.
Reasoning: CDH011 reports a very thick (400m) and high-grade (0.67% Cu) intercept that confirms the vertical continuity of the Cobrasco porphyry system.
Positive factors
- significant thickness and grade
- confirms vertical continuity
- high-grade sub-intervals
- near-surface mineralization
Negative factors
- apparent width only
Facts used in scoring: 14
Classification and evidence
Step-Out Extensionpositive
Mineralization extended beyond the previously known limit.
Why it applies: The company is using substantial step-outs to test the extent of the Cobrasco system.
Evidence · text
“systematically advancing a wide-spaced scout drilling program using substantial step-outs”
QA/QC Disclosedpositive
Release includes QA/QC disclosure — certified lab, QP sign-off, or stated methods (blanks, standards, duplicates).
Why it applies: Release details sampling protocols, laboratory accreditation (ALS), and supervision.
Evidence · text
“All sampling was conducted in nominal 2m intervals with cut-lines marked by the supervising geologists”
Apparent Width Onlynegative
Interval given as downhole width with no true width or drill orientation — apparent width may overstate true thickness.
Why it applies: Note 2 explicitly states reported interval widths are downhole lengths and may not represent true widths.
Evidence · text
“Reported interval widths are downhole lengths and may not represent the true widths of mineralization.”

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.
