## Minestarters Atlas summary

Goldcliff Resource Corporation reports encouraging initial metallurgical results using Dundee Sustainable Technologies' patented CLEVR non-cyanide gold recovery process. Testing on a York-zone composite \(0.74 g/t Au\) achieved 88% gold recovery following thermal oxidation pre-treatment.

Reasoning: Initial testing of a novel non-cyanide process \(CLEVR\) showed 88% recovery on a low-grade composite, which is a significant technical milestone for environmental de-risking, though results are preliminary.

- Positive factor: encouraging initial recovery

- Positive factor: non-cyanide environmentally friendly process

- Positive factor: non-acid-generating residue

- Negative factor: preliminary results

- Negative factor: requires further optimization

- Negative factor: low head grade

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. After one hour of CLEVR leaching, an 88% gold recovery was recorded.

**Bench Scale Only**

Polarity: negative

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

Why it applies: Results are described as preliminary laboratory testing on composites.

Evidence · text

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

**Single Domain Only**

Polarity: negative

Definition: Testing limited to one composite or domain — representativeness not established.

Why it applies: only one composite was 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.
