Marg Volcanogenic Sulphide Deposit Geology and Stratigraphy

The Marg deposit is a Cu-Zn-Pb-Au-Ag volcanogenic massive sulphide deposit hosted within Devonian-Mississippian Earn Group and Mississippian Keno Hill Quartzite rocks. Geological mapping and drill core re-analysis was completed to reassess the deposit's economic potential. The data was published by the Government of Yukon and last updated on April 17, 2026.

Use Cases

• Assessing property-scale economic potential based on geological mapping and drill core analysis
• Correlating deposit structures with regional-scale features like the Robert Service Thrust
• Evaluating regional exploration potential based on discovered comparable stratigraphy and new sulphide occurrences
• Studying implications for regional tectonics based on probable rift-related volcanism and mineralization

Strengths

• Data is based on geological mapping and re-analysis of drill core
• Description provides specific geological context including host rocks (Earn Group, Keno Hill Quartzite) and structural generations
• Platform tags provide clear domain classification

Limitations

• Column-level documentation is absent; field semantics must be inferred after download
• Row count is unknown, which may limit suitability assessment
• Description metadata is limited; actual data quality requires manual inspection after download
