Yukon Placer Mine Sediment Grain Size and Water Quality Samples

Yukon placer mines were sampled for sediment grain size distribution and water quality by Indian and Northern Affairs Canada in 1998. The program collected data from bank material and upstream and discharge water to investigate relationships between pay gravel grain size and effluent levels. This data was intended for use in the complete review of the Yukon Placer Authorization in 2001.

Use Cases

• Interpret fluvial depositional environments based on grain size distribution of pay gravels.
• Assess the impact of mining on water quality based on suspended solids concentration data.
• Optimize gold liberation treatment processes based on clay and silt content in gold-bearing gravels.
• Support regulatory reviews of mining authorizations based on environmental monitoring data.

Strengths

• Data collection initiated by a government department (Indian and Northern Affairs Canada).
• Sampling program designed to investigate a specific relationship between grain size and effluent levels.
• Data intended for a formal regulatory review (Yukon Placer Authorization in 2001).

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
