Minestarters Atlas analysis
Summary
Collective Mining reported strong metallurgical test results for the Apollo system, achieving 95% gold, 92% silver, and 85% copper recoveries using conventional methods. The program also demonstrated high tungsten recovery of up to 74% and significant gold amenability to gravity concentration.
Reasoning: The release reports robust metallurgical recoveries for a polymetallic system using conventional methods, including high gold and silver recoveries and strong gravity response.
Positive factors
- High gold recovery (95%)
- Strong gravity response for gold
- High tungsten recovery (74%)
- High-purity tungsten concentrate (95% scheelite)
- QA/QC disclosed with accredited lab
Negative factors
- Tungsten recovery (74%) is moderate compared to precious metals
Facts used in scoring: 5

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.
