## Minestarters Atlas summary

Bayhorse Silver has reported highly successful selective antimony leaching results, achieving approximately 99.9% recovery from its refractory concentrate. This proprietary process aims to separate antimony from silver, copper, and zinc, potentially significantly increasing the overall recoveries of these critical minerals.

Reasoning: The report demonstrates near-total \(99.9%\) selective leaching of antimony from a complex refractory concentrate, which is a significant technical milestone for the project's economics.

- Positive factor: exceptional antimony recovery

- Positive factor: addresses refractory mineralogy

- Positive factor: potential to unlock value in other metals

- Negative factor: proprietary process not yet proven at pilot scale

Facts used in scoring: 3

## Classification and evidence

**High Recovery**

Polarity: positive

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

Why it applies: Antimony recovery of 99.9% is exceptional.

Evidence · text

> 99.9% selectively removed

**Refractory Ore**

Polarity: negative

Definition: Ore requires oxidation/pressure treatment before recovery — a processing and recovery risk.

Why it applies: The concentrate is explicitly described as refractory tetrahedrite.

Evidence · text

> "refractory tetrahedrite" Bayhorse Silver Mine concentrate

**QP/CP Signed**

Polarity: positive

Story-specific tag

Definition: Qualified Person \(QP\) or Competent Person \(CP\) named and signed off — a member of a recognized professional association \(e.g., AusIMM, SME, AIG, P.Geo\) with relevant experience.

Why it applies: Mark Abrams, AIPG, a Qualified Person, has approved the technical content.

Evidence · text

> Mark Abrams, AIPG, a Qualified Person and Director of the Company has prepared, supervised the preparation of, or approved the technical content

## 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.
