## Minestarters Atlas summary

Great Bear Resources reported high gold recoveries between 95.2% and 99.2% from preliminary metallurgical tests on its LP Fault zone at the Dixie Project in Ontario. The results confirm that gold mineralization is free-milling and readily soluble across all grades, indicating amenability to conventional processing with low cyanide consumption. This positive outcome significantly de-risks the project's processing pathway, with further testing underway to investigate gravity recovery potential.

Reasoning: Great Bear reported excellent preliminary gold recoveries ranging from 95.2% to 99.2% from LP Fault samples, confirming the free-milling nature of the gold across various grades and mineralogical styles with low cyanide consumption, which significantly de-risks the project's processing. The results, though from bench-scale bottle roll tests, are highly positive for the project's future development.

- Positive factor: High gold recoveries \(95.2% to 99.2%\) across all tested grades and mineralogical styles for the LP Fault zone.

- Positive factor: Gold is confirmed to be free-milling and non-refractory, meaning conventional processing routes are applicable.

- Positive factor: Low cyanide consumption rates indicate favorable operating costs.

- Positive factor: Metallurgical results are in line with high operational recoveries at other Red Lake district mines.

- Positive factor: QP sign-off and accredited laboratory involvement provide high confidence in the results.

- Negative factor: Tests are preliminary bottle roll tests, not locked-cycle or pilot scale, which are more representative of commercial operations.

- Negative factor: While variability was considered, the sample set is limited to ten 1kg composites, not full domain coverage.

Facts used in scoring: 22

## 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 recoveries for the LP Fault zone ranged from 95.2% to 99.2%, which is at or above the exceptional band for gold processing via a mill/CIL route.

Evidence · text

> 95.2% to 99.2% Gold Recoveries

**Free Milling**

Polarity: positive

Definition: Simple, clean ore amenable to standard processing without oxidation.

Why it applies: The document explicitly states that LP Fault gold mineralization is not refractory and all samples were described as 'free-milling'.

Evidence · text

> LP Fault gold mineralization is not refractory. All samples, regardless of grade, were described as "free-milling"

**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: Andrew Kelly, P.Eng., of Blue Coast Research Ltd., a Qualified Person for NI 43-101, approved the metallurgical test program results.

Evidence · text

> Results for the metallurgical test program were provided and approved by Andrew Kelly , P.Eng., of Blue Coast Research Ltd., a Qualified Person for the purpose of National Instrument 43-101.

**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 that Great Bear adheres to industry-leading QA/QC practices and details some of the methods used for drill core sampling and analysis.

Evidence · text

> Great Bear adheres to industry-leading quality assurance / quality control \(QA/QC\) practices in data collection, analysis and disclosure

**Bench Scale Only**

Polarity: negative

Definition: Only preliminary bench tests completed — no locked-cycle or pilot work.

Why it applies: The metallurgical tests were conducted using a 'standard 48 hour bottle roll procedure', which is a bench-scale test and not representative of continuous pilot or commercial operations.

Evidence · text

> standard 48 hour bottle roll procedure

**Single Domain Only**

Polarity: negative

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

Why it applies: While the samples covered a range of grades and mineralogical styles, they represent 'the most mineralogically complex intervals' and 'higher accessory sulphide content than the zone's average', indicating a focus on specific domains rather than comprehensive variability coverage.

Evidence · text

> The samples reported here represent the most mineralogically complex intervals drilled to date at the LP Fault and have higher accessory sulphide content than the zone's average.

**Mill Route**

Polarity: neutral

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

Why it applies: The processing route involves cyanidation \(sodium cyanide solution\) and bottle roll tests, which are characteristic of a mill/CIL processing route.

Evidence · text

> standard 48 hour bottle roll procedure at 40% solids, using a 1.0 g/L sodium cyanide solution.

## 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.
