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 factors
- High recovery (88%) achieved with non-cyanide process
- Environmentally friendly zero-effluent design
- Non-acid-generating residue confirmed by TCLP
Negative factors
- Results are preliminary
- Requires thermal oxidation pre-treatment
- Additional optimization and testing required
Facts used in scoring: 1
Classification and evidence
Mill Routeneutral
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 Onlynegative
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”

Reasoning: 88% recovery on a low-grade composite (0.74 g/t) using a novel process is a strong technical signal.
Positive factors
- 88% recovery is strong for a non-cyanide/preliminary test
Negative factors
- Requires pre-treatment
- Preliminary stage
Evidence · text
“Testing of York-zone drill core achieved 88% gold recovery using the CLEVR process with a thermal oxidation pre-treatment.”
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.
