## Minestarters Atlas summary

Goldcliff Resource Corporation reports encouraging preliminary metallurgical results for its Panorama Ridge project using Dundee Sustainable Technologies' CLEVR non-cyanide process. Testing on a York-zone composite achieved 88% gold recovery following thermal oxidation pre-treatment.

Reasoning: Initial metallurgical testing shows promising gold recovery using an innovative non-cyanide process, which could significantly reduce environmental risk and CAPEX/OPEX related to tailings management.

- Positive factor: High recovery \(88%\) achieved with non-cyanide process

- Positive factor: Environmentally friendly zero-effluent design

- Positive factor: Non-acid-generating residue confirmed by TCLP

- Negative factor: Results are preliminary

- Negative factor: Requires thermal oxidation pre-treatment

- Negative factor: Additional optimization and testing required

Facts used in scoring: 1

## Classification and evidence

**Mill Route**

Polarity: neutral

Definition: Processing via mill or concentrator \(CIL, CIP, tank leach, flotation\).

Why it applies: The process involves crushing, blending, thermal oxidation, and leaching.

Evidence · text

> crushed and blended into a composite grading 0.74 g/t Au. Following thermal oxidation, the composite tested at 0.71 g/t Au.

**Bench Scale Only**

Polarity: negative

Definition: Only preliminary bench tests completed — no locked-cycle or pilot work.

Why it applies: The results are described as preliminary laboratory work and require further optimization.

Evidence · text

> While these results are preliminary and additional test work and optimization will be required

## 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.
