Summary
Great Bear Resources reported excellent preliminary metallurgical test results for its LP Fault zone at the Dixie Project in Ontario, Canada, with gold recoveries ranging from 95.2% to 99.2%. The tests confirmed that gold is free-milling and readily soluble across all grades and ore types, requiring no complex processing like autoclaving. These positive results, achieved through standard cyanidation bottle roll tests, significantly de-risk the project's future development and align with high operational recoveries seen in the Red Lake district.
Reasoning: The preliminary metallurgical test results for the LP Fault zone show consistently high gold recoveries (95.2% to 99.2%) across various grades and ore types, indicating free-milling and readily soluble gold, which significantly de-risks the project's processing pathway and aligns with regional operational benchmarks.
Positive factors
- High gold recoveries (95.2% to 99.2%) across all tested grades and ore types.
- Gold is free-milling and readily soluble, indicating simple processing.
- Low cyanide consumption rates (0.12 to 0.27 kg/t) for the LP Fault samples.
- No autoclave processing (POX/BIOX) required, reducing CAPEX and OPEX.
- Results are in line with high operational gold recoveries at mines in the Red Lake district.
- Potential for significant gravity circuit gold recoveries.
Negative factors
- Tests are preliminary and conducted at bench-scale (bottle roll), not pilot scale.
- LP Fault tests are focused on a single domain, limiting variability understanding across the entire deposit.
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: The document reports gold recoveries ranging from 95.2% to 99.2%, which are at or above the exceptional band for the mill_cil processing 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 'Gold is Free Milling and Readily Soluble at All Grades' and 'LP Fault gold mineralization is not refractory. All samples, regardless of grade, were described as "free-milling"'.
Evidence · text
“Gold is Free Milling and Readily Soluble at All Grades”
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.
Evidence · text
“standard 48 hour bottle roll procedure”
Single Domain Onlynegative
Testing limited to one composite or domain — representativeness not established.
Why it applies: The LP Fault tests are described as representing 'the most mineralogically complex intervals drilled to date at the LP Fault', indicating a focus within a single deposit domain rather than comprehensive variability across multiple distinct domains.
Evidence · text
“The samples reported here represent the most mineralogically complex intervals drilled to date at the LP Fault”
Multi-Domain Testedpositive
Variability across ore domains (oxide, transition, fresh) has been addressed.
Why it applies: The historical tests in Table 3 include samples from 'Hinge Zone Comp', 'DL Argillite Comp', and 'DL High Sulphide Comp', indicating testing across multiple distinct ore domains.

Context: CN-1
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: The results for the metallurgical test program were provided and approved by Andrew Kelly, P.Eng., of Blue Coast Research Ltd., a Qualified Person.
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.”
Refractory Orenegative
Ore requires oxidation/pressure treatment before recovery — a processing and recovery risk.
Why it applies: The document explicitly states that 'LP Fault gold mineralization is not refractory' and 'Autoclave processing will not be required'.
Evidence · text
“LP Fault gold mineralization is not refractory. All samples, regardless of grade, were described as "free-milling"”
Gravity Routeneutral
Gravity separation forms a material part of the flowsheet.
Why it applies: the document describes a gravity route ("gravity")

Reasoning: This historical test shows a lower gold recovery and very high cyanide consumption for a Dixie Limb Argillite composite, indicating potential processing challenges for this material.
Negative factors
- Recovery (88.3%) is below the strong band for mill_cil.
- Very high cyanide consumption (4.47 kg/t).
- Test is bench-scale (bottle roll).
- Historical data, not new results.

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.
