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 factors
- High gold recoveries (95.2% to 99.2%) across all tested grades and mineralogical styles for the LP Fault zone.
- Gold is confirmed to be free-milling and non-refractory, meaning conventional processing routes are applicable.
- Low cyanide consumption rates indicate favorable operating costs.
- Metallurgical results are in line with high operational recoveries at other Red Lake district mines.
- QP sign-off and accredited laboratory involvement provide high confidence in the results.
Negative factors
- Tests are preliminary bottle roll tests, not locked-cycle or pilot scale, which are more representative of commercial operations.
- 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 Recoverypositive
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 Millingpositive
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 Signedpositive · Story-specific tag
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 Disclosedpositive · Story-specific tag
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 Onlynegative
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 Onlynegative
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 Routeneutral
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.”

Reasoning: A good gold recovery of 92.9% was achieved from a Dixie Limb Argillite composite sample (10.07 g/t Au), but with moderate cyanide consumption. This is historical data previously reported.
Positive factors
- Good gold recovery of 92.9% from Dixie Limb Argillite composite.
Negative factors
- Bench-scale bottle roll test only.
- Limited domain coverage.
- Cyanide consumption of 1.1 kg/t is moderate to high.
- Historical data, not new.

Reasoning: A lower gold recovery of 88.3% was achieved from a Dixie Limb Argillite composite sample (10.89 g/t Au) with very high cyanide consumption, suggesting potential processing challenges. This is historical data previously reported.
Negative factors
- Lower gold recovery of 88.3% for a mill route.
- Very high cyanide consumption of 4.47 kg/t, indicating potential processing challenges or refractory characteristics.
- Bench-scale bottle roll test only.
- Limited domain coverage.
- Historical data, not new.

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.
