## Minestarters Atlas summary

Hanstone Gold Corp. has announced preliminary metallurgical results from a 54.5-kg bulk sample at its Doc Property in British Columbia. The testing demonstrated high gold recovery, with a gravity-leach flowsheet achieving 95.3% recovery from high-grade material averaging 32.2 g/t Au.

Reasoning: The release reports strong preliminary metallurgical results from a bulk sample, demonstrating high gold recovery potential using a gravity-leach circuit.

- Positive factor: High gold recovery \(95.3%\) achieved via gravity-leach flowsheet

- Positive factor: Excellent head grades \(avg 32.2 g/t Au\)

- Positive factor: Successful preliminary bulk sample testing

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: Gravity-leach achieved 95.3% gold recovery, which is in the exceptional band for gold mill routes.

Evidence · text

> Combined gravity concentration and cyanide leaching \(gravity-leach\) achieved overall gold recovery of 95.3%.

**Mill Route**

Polarity: neutral

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

Why it applies: Testing involved gravity concentration and cyanide leaching.

Evidence · text

> Combined gravity concentration and cyanide leaching \(gravity-leach\)

**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 identifies a Qualified Person \(Case Lewis P.Geo.\) and mentions testing conducted by Sepro Laboratories.

Evidence · text

> Technical information in this news release has been reviewed and approved by Case Lewis P.Geo., a "Qualified Person"

**Gravity Route**

Polarity: neutral

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

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

**Single Domain Only**

Polarity: negative

Definition: Testing limited to one composite or domain — representativeness not established.

Why it applies: only one composite was tested

## 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.
