Summary
Lahontan Gold Corp. reported high cyanide (CN) extractable recoveries of 81% for gold and 60% for silver from pulp samples at the West Santa Fe project. These results exceed historical projections and support the potential for heap leach processing.
Reasoning: The cyanide extraction results (81% Au, 60% Ag) are high and exceed historical projections, supporting the amenability of the project to heap leach processing.
Positive factors
- High cyanide extraction rates for both gold and silver
- Results exceed historical projected recoveries
- QA/QC protocols clearly disclosed
- Validates previous metallurgical testing
Negative factors
- Results are based on pulp samples from RC drilling rather than full-scale metallurgical testing
Facts used in scoring: 2
Classification and evidence
High Recoverypositive
Recovery at or above the exceptional band for the commodity and processing route.
Why it applies: Gold recovery of 81% is high for cyanide extraction.
Evidence · text
“This is a very high CN extraction ratio”
QA/QC Disclosedpositive · Story-specific tag
Release includes QA/QC disclosure — certified lab, QP sign-off, or stated methods (blanks, standards, duplicates).
Why it applies: The release details specific QA/QC protocols including blanks, CRMs, and duplicates.
Evidence · text
“Lahontan conducts an industry standard QA/QC program”
Heap Leach Routeneutral
Processing via heap leach — lower CAPEX and OPEX, lower recovery expected.
Why it applies: The testing was designed to mimic potential cyanide heap leach processing.
Evidence · text
“mimics potential gold and silver recoveries utilizing CN heap leach processing”

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.
