Summary
Blue Jay Gold reported maiden metallurgical test results from the Becker-Cochran antimony occurrence at the Steller Project, producing a 66.9% Sb concentrate at 93.9% recovery. The concentrate has been submitted to three North American processing groups for refining tests to produce finished antimony products.
Reasoning: Successful maiden flotation testwork producing high-grade antimony concentrate with strong recovery, though results are preliminary and lack variability testing.
Positive factors
- High concentrate grade (66.9% Sb) exceeding premium thresholds
- Strong recovery (93.9%)
- Maiden test work successful
- QA/QC disclosed with ALS lab and QP sign-off
Negative factors
- Bench scale only (preliminary)
- No variability studies completed
- Mercury (Hg) noted in concentrate aliquot
Facts used in scoring: 3
Classification and evidence
High Recoverypositive
Recovery at or above the exceptional band for the commodity and processing route.
Why it applies: 93.9% Sb recovery is exceptional for a flotation process.
Evidence · text
“94% Sb recovery”
Bench Scale Onlynegative
Only preliminary bench tests completed — no locked-cycle or pilot work.
Why it applies: Results are from laboratory-scale rougher-cleaner testing.
Evidence · text
“These results are based on laboratory-scale rougher-cleaner testing and are preliminary in nature”
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: Release mentions ALS laboratory, internal QA/QC, and QP sign-off.
Evidence · text
“under documented chain of custody and modern quality assurance and quality controls”
Deleterious Elements Presentnegative · Story-specific tag
Penalty elements (arsenic, antimony, etc.) or refractory concerns noted in the release.
Why it applies: Mercury (Hg) was noted in concentrate aliquot.
Evidence · text
“Hg in concentrate aliquot up 1,100 ppm”
Mill Routeneutral
Processing via mill or concentrator (CIL, CIP, tank leach, flotation).
Why it applies: the document describes a flotation route ("flotation")
Single Domain Onlynegative
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.
