Summary
Silver47 has reported successful metallurgical testing on the Belmont tailings at the Hughes Project, achieving 80% silver and 77% gold extraction via agitated cyanide leach at a 53 µm grind. While heap leach testing was unsuccessful due to permeability issues, the results support further evaluation of a mill-based processing route for the project's inferred resource.
Reasoning: The metallurgical results demonstrate high recovery potential for the tailings, specifically via an agitated leach route, which provides a clear technical path for reprocessing.
Positive factors
- Strong extraction rates for both silver and gold
- Low refractory/preg-robbing indicators (low carbon and sulphur)
- Clear processing pathway identified (agitated cyanide leach)
- Grind size optimization shows clear upside
Negative factors
- Heap leach route failed permeability testing
- Extraction results reported on a calculated-head basis rather than measured
Facts used in scoring: 4
Classification and evidence
Mill Routeneutral
Processing via mill or concentrator (CIL, CIP, tank leach, flotation).
Why it applies: The program supports further evaluation of agitated cyanide leaching with carbon adsorption.
Evidence · text
“The program supports further evaluation of agitated cyanide leaching with carbon adsorption as a potential processing route”
Bench Scale Onlynegative
Only preliminary bench tests completed — no locked-cycle or pilot work.
Why it applies: Testing was conducted on composites using agitated leach and heap leach methods at a lab scale.
Evidence · text
“Forte Analytical LLC of Fort Collins, Colorado conducted a staged metallurgical program”
Heap Leach Routeneutral
Processing via heap leach — lower CAPEX and OPEX, lower recovery expected.
Why it applies: the document describes a heap_leach route ("heap leach")
Multi-Domain Testedpositive
Variability across ore domains (oxide, transition, fresh) has been addressed.
Why it applies: 2 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.
