## Minestarters Atlas summary

Goldsky Resources has reported positive metallurgical test results for its Barsele gold project in Sweden. The gravity concentration and cyanide bottle-roll leach tests achieved overall gold recoveries of approximately 90% for both the Central and Avan ore bodies.

Reasoning: Positive metallurgical test results for the Barsele project showing ~90% overall gold recovery using a conventional flowsheet, supporting the ongoing PEA.

- Positive factor: High overall gold recoveries \(90% range\)

- Positive factor: Fast leach kinetics

- Positive factor: Conventional gravity-cyanidation flowsheet compatibility

- Positive factor: QA/QC disclosed with ISO 17025 accredited lab

Facts used in scoring: 9

## Classification and evidence

**High Recovery**

Polarity: positive

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

Why it applies: Overall gold recoveries of 89.6% and 90.8% are in the exceptional/strong band for gold leach.

Evidence · text

> overall mass balance gold recoveries of 89.6% for the Central composite sample and 90.8% for the Avan composite sample

**Mill Route**

Polarity: neutral

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

Why it applies: The test work involves milling and gravity concentration followed by cyanide leach.

Evidence · text

> gravity concentration and cyanide bottle-roll leach testing

**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: The release mentions the use of an ISO 17025 accredited laboratory and digital sample tracking.

Evidence · text

**Gravity Route**

Polarity: neutral

Definition: Gravity separation forms a material part of the flowsheet.

Why it applies: the document describes a gravity route \("gravity"\)

**Multi-Domain Tested**

Polarity: positive

Definition: Variability across ore domains \(oxide, transition, fresh\) has been addressed.

## 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.
