Summary
Silver47 has reported successful metallurgical testing on the Belmont tailings at the Hughes Project in Nevada, 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 2.74 Moz AgEq inferred resource.
Reasoning: The metallurgical results demonstrate high recovery potential for the tailings, though the failure of heap leach testing narrows the processing options to more capital-intensive agitated leaching.
Positive factors
- Strong silver and gold extraction results from agitated cyanide leach
- Finer grind size shows clear improvement in recoveries
- Low organic carbon and sulphur suggest low refractory/preg-robbing risk
- Identified a clear processing pathway (agitated leach) over heap leach
Negative factors
- Heap leach testing failed to sustain permeability
- Extraction results are reported on a calculated-head basis rather than measured heads
Facts used in scoring: 7
Classification and evidence
Mill Routeneutral
Processing via mill or concentrator (CIL, CIP, tank leach, flotation).
Why it applies: Testing indicates agitated cyanide leaching is the leading processing approach.
Evidence · text
“agitated cyanide leaching, as opposed to heap leaching, is the leading processing approach”
Free Millingpositive
Simple, clean ore amenable to standard processing without oxidation.
Why it applies: Low organic carbon and sulphur suggest low potential for preg-robbing or refractory behaviour.
Evidence · text
“Sulphide sulphur averaged 0.50% and organic carbon 0.13%, suggesting low potential for preg-robbing or refractory behaviour.”
Inferred Resourcenegative
Speculative category — limited drilling, geological continuity assumed but not confirmed. Cannot support economic studies alone.
Why it applies: The metallurgical testing is associated with an inferred mineral resource.
Evidence · text
“associated with the inferred mineral resource of 1.8 Moz silver and 11 koz gold”
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.
