Coffee Project Gold Deposit Geology and Bedrock Mapping Updates

Government of Yukon mapping updates detail the Coffee Project gold deposit's structural history and formation depth. Recent work highlights a previously unknown secondary phase of the Permian Sulphur Creek suite and a shallow formation depth of 1–3 km. The dataset includes geochemistry suggesting a Au-As-Sb ± Ag-Pb-Te-W-Zn-K metal association and implications for deposit classification.

Use Cases

• Classifying gold deposit types based on structural and geochemical characteristics described in the mapping.
• Analyzing the relationship between mineralized dikes and regional fault systems like the Coffee Creek fault.
• Modeling shallow-depth (1–3 km) ore formation processes using the updated structural analysis.
• Correlating metal associations (Au-As-Sb ± Ag-Pb-Te-W-Zn-K) with potential magmatic fluid sources.

Strengths

• Includes recent mapping efforts and new geochronology that updated the location of the Coffee Creek fault.
• Provides a specific formation depth estimate of 1–3 km based on structural analysis.
• Contains multi-element geochemistry highlighting a specific Au-As-Sb ± Ag-Pb-Te-W-Zn-K metal association.

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 Coffee Project in west-central Yukon.
