Analysis by Minestarters Atlas
Minestarters Atlas analysis
Summary
1911 Gold has reported strong metallurgical test results for its True North and Ogama-Rockland gold projects in Manitoba. True North showed a 95.5% leach recovery, while Ogama-Rockland achieved 97.7% recovery via leaching reground flotation concentrate.
Reasoning: Strong metallurgical recoveries (up to 97.7% leach) reported for two key projects, supporting future processing viability.
Positive factors
- High leach recoveries reported at both projects
- Gravity recovery stage is effective at True North
- Ogama-Rockland material described as clean and amenable to True North mill
Facts used in scoring: 5
Classification and evidence
High Recoverypositive
Recovery at or above the exceptional band for the commodity and processing route.
Why it applies: Leach recoveries of 95.5% and 97.7% are exceptional for gold.
Evidence · text
“leach recovery averaged 95.5% gold”
Mill Routeneutral
Processing via mill or concentrator (CIL, CIP, tank leach, flotation).
Why it applies: the document describes a flotation route ("flotation")
Gravity Routeneutral
Gravity separation forms a material part of the flowsheet.
Why it applies: the document describes a gravity route ("gravity")
Multi-Domain Testedpositive
Variability across ore domains (oxide, transition, fresh) has been addressed.
Why it applies: 3 distinct composites were 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.
