Minestarters Atlas analysis
Summary
Tudor Gold has reported positive metallurgical test results for the Goldstorm Deposit at Treaty Creek, demonstrating that saleable gold and copper concentrates can be produced from the Upper, Central, and Lower zones. The locked-cycle tests showed strong gold recoveries, particularly in the Upper and Lower zones, and confirmed the potential for blended feed processing.
Reasoning: The metallurgical program successfully demonstrated the ability to produce saleable concentrates across multiple deposit zones with strong gold recoveries.
Positive factors
- High gold recoveries in Upper and Lower zones
- Saleable copper and gold concentrates produced from Central Zone
- High sulphur grades (>45%) noted for marketability
- Locked-cycle testwork completed
Negative factors
- Minor optimization required to reduce copper losses to sulphide concentrate
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 recoveries in Upper (86.3%) and Lower (87.3%) zones are strong for flotation.
Evidence · text
“achieving excellent gold recoveries. The Upper Zone concentrate recovered 86% of the gold”
Mill Routeneutral
Processing via mill or concentrator (CIL, CIP, tank leach, flotation).
Why it applies: Flowsheet involves flotation and regrinding.
Evidence · text
“followed by conventional sulphide flotation”
Bench Scale Onlynegative
Only preliminary bench tests completed — no locked-cycle or pilot work.
Why it applies: Results are from locked-cycle tests on composites, which are preliminary compared to pilot scale.
Evidence · text
“The results of the locked-cycle test work are set out in Table 1”
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.
