Minestarters Atlas analysis
Summary
Cartier Resources reported metallurgical testwork results for the Cadillac Project's Main Sector, achieving an average gold recovery of 96.3%. The results, which include first-time data for the East Chimo and West Nordeau deposits, exceed the 93.1% recovery assumed in the 2023 PEA.
Reasoning: The metallurgical results show high gold recovery (96.3%) which exceeds both the previous PEA and historical mine averages, significantly de-risking the processing profile for the Main Sector.
Positive factors
- High gold recovery (96.3%)
- Recovery exceeds 2023 PEA and historical mine averages
- Low cyanide consumption
- Established first-time data for satellite deposits
Negative factors
- Moderately hard material (Bond Work Index 13.1-14.3 kWh/t)
- Presence of pyrrhotite and arsenopyrite
Facts used in scoring: 6
Classification and evidence
High Recoverypositive
Recovery at or above the exceptional band for the commodity and processing route.
Why it applies: Gold recovery of 96.3% is in the exceptional band for a mill route.
Evidence · text
“gold extraction for Main Sector reached 96.3%”
Mill Routeneutral
Processing via mill or concentrator (CIL, CIP, tank leach, flotation).
Why it applies: Flowsheet includes crushing, grinding, cyanide leach and gravity separation.
Evidence · text
“Conventional milling flowsheet with crushing, grinding, cyanide leach and gravity separation.”
Free Millingpositive
Simple, clean ore amenable to standard processing without oxidation.
Why it applies: High recovery achieved with standard cyanide leaching and pre-aeration.
Evidence · text
“Achieving gold recoveries above 96% in the Main Sector highlights the metallurgical characteristics”
Gravity Routeneutral
Gravity separation forms a material part of the flowsheet.
Why it applies: the document describes a gravity route ("gravity")
POX/BIOX Routeneutral
Pressure or bio-oxidation for refractory ore — high CAPEX and OPEX.
Why it applies: the document describes a pox_biox route ("roasting")
Multi-Domain Testedpositive
Variability across ore domains (oxide, transition, fresh) has been addressed.
Why it applies: 4 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.
