## Minestarters Atlas 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 factor: High gold recoveries in Upper and Lower zones

- Positive factor: Saleable copper and gold concentrates produced from Central Zone

- Positive factor: High sulphur grades \(>45%\) noted for marketability

- Positive factor: Locked-cycle testwork completed

- Negative factor: Minor optimization required to reduce copper losses to sulphide concentrate

Facts used in scoring: 6

## Classification and evidence

**High Recovery**

Polarity: positive

Definition: 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 Route**

Polarity: neutral

Definition: 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 Only**

Polarity: negative

Definition: 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 Tested**

Polarity: positive

Definition: Variability across ore domains \(oxide, transition, fresh\) has been addressed.

Why it applies: 3 distinct composites were tested
