## Minestarters Atlas 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 factor: High gold recovery \(95%\)

- Positive factor: Strong gravity response for gold

- Positive factor: High tungsten recovery \(74%\)

- Positive factor: High-purity tungsten concentrate \(95% scheelite\)

- Positive factor: QA/QC disclosed with accredited lab

- Negative factor: Tungsten recovery \(74%\) is moderate compared to precious metals

Facts used in scoring: 5

## Classification and evidence

**High Recovery**

Polarity: positive

Definition: Recovery at or above the exceptional band for the commodity and processing route.

Why it applies: Gold recovery of 95% and 96% exceeds exceptional thresholds.

Evidence · text

> 95% Gold

**Mill Route**

Polarity: neutral

Definition: Processing via mill or concentrator \(CIL, CIP, tank leach, flotation\).

Why it applies: Uses conventional gravity concentration, flotation and cyanidation.

Evidence · text

> conventional gravity concentration, flotation and cyanidation methods

**QA/QC Disclosed**

Polarity: positive

Story-specific tag

Definition: Release includes QA/QC disclosure — certified lab, QP sign-off, or stated methods \(blanks, standards, duplicates\).

Why it applies: Release mentions ALS Canada Ltd. and ISO/IEC 17025 accreditation.

Evidence · text

> conforms to the requirements of ISO/IEC 17025

## 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.
