Enhanced Stream Sediment Geochemistry for Yukon Mineral Exploration

New geochemical data from re-analysis of archived stream sediment samples, assessed using weighted sums modeling and catchment basin analysis. The release is part of a regional assessment covering a large part of Yukon, presented as catchment maps and associated data files. It was published by the Government of Yukon and last updated on 2026-05-20.

Use Cases

• Identify areas with geochemical anomalies for base and precious-metal deposits based on commodity and pathfinder element abundances.
• Apply weighted sums modeling for mineral prospectivity mapping using the provided catchment basin analysis results.
• Conduct regional geochemical assessments for parts of Yukon based on the stream sediment sampling methodology.

Strengths

• Data is derived from a regional assessment covering a large part of Yukon.
• Analysis includes both commodity and pathfinder elements for multiple deposit types.
• Results are presented using two modeling approaches, as described in the accompanying methodology report (YGS Open File 2015-10).

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.
