Enhanced Stream Sediment Geochemistry for Yukon NTS 115J and 115K

Yukon stream sediment geochemical data for NTS map sheets 115J and 115K. The data includes re-analyzed samples assessed using weighted sums modeling and catchment basin analysis to highlight areas with geochemical responses consistent with base and precious-metal mineral deposits. This release is part of a regional assessment by the Government of Yukon.

Use Cases

• Identify prospective areas for mineral exploration based on commodity and pathfinder element abundances.
• Conduct catchment basin analysis for regional geochemical patterns using the provided maps and data files.
• Model geochemical responses for various deposit types using the weighted sums modeling approach described.

Strengths

• Data is part of a regional assessment covering a large part of Yukon.
• Analysis uses two distinct modeling approaches: weighted sums and catchment basin analysis.
• Includes both commodity and pathfinder element evaluations for multiple deposit types.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect geographic bias inherent to the Yukon region.
