Minestarters Atlas analysis
Summary
Revival Gold has released interim results from its 2026 Mercur Project column leach testing program. The testing, conducted by KCA, evaluates the impact of crush size and cement agglomeration on gold and silver leachability for both oxide and refractory materials in support of a Prefeasibility Study.
Reasoning: Interim column leach results show strong gold recovery for oxide ores but highlight significant metallurgical complexity in refractory domains.
Positive factors
- amenability to conventional crushed ore heap leaching
- high gold recovery in oxide domains (up to 94%)
Negative factors
- low gold recovery in some refractory domains (1%)
- refractory material shows lower leachability
Facts used in scoring: 4
Classification and evidence
Mill Routeneutral
Processing via mill or concentrator (CIL, CIP, tank leach, flotation).
Why it applies: The testing is described as column leach testing in support of a PFS, which is a standard component of heap leach/mill flowsheet studies.
Evidence · text
“metallurgical column leach testing”
Refractory Orenegative
Ore requires oxidation/pressure treatment before recovery — a processing and recovery risk.
Why it applies: The document explicitly mentions testing refractory (sulfidic and carbonaceous) materials.
Evidence · text
“assessing the leachability of refractory (sulfidic and carbonaceous) materials”
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 leaching")
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.
