Placer and Lode Gold Composition in the Stewart River Map Area, Yukon

A reconnaissance study characterizes the composition of gold from several placer streams in the Stewart River map area, western Yukon. The Government of Yukon conducted the study to determine the likely style(s) of lode mineralization from which the placer gold was derived. Results indicate compositions consistent with epithermal and intrusion-related gold sources.

Use Cases

• Identifying epithermal gold sources based on low fineness, low copper, and high mercury compositions
• Locating intrusion-related gold deposits based on high fineness, high copper, and low mercury compositions
• Correlating placer gold composition with specific drainage basins like Thistle/Kirkman
• Characterizing gold from colluvium in exploration pits for source comparison

Strengths

• Study focuses on specific geographic area: Stewart River map area, western Yukon
• Analysis compares gold from multiple named streams: Eureka, Black Hills, Moosehorn Range, Thistle, Kirkman, Blueberry
• Results differentiate between two distinct gold source types: epithermal and intrusion-related

Limitations

• Column-level documentation is absent; field semantics must be inferred after download
• Row count is unknown, which may limit suitability assessment
• Sample data is unavailable, preventing preview of data structure
