Yukon Mineral Potential Maps with Machine Learning Classification

Yukon Geological Survey's mineral potential maps cover the Beaver River watershed, Dawson, Teslin, Na-Cho Nyäk Dun, and Ross River regions. The update paper describes methodological improvements, including a new unsupervised machine learning algorithm for classification and lithology-based stream sediment anomaly detection. The maps are produced by the Government of Yukon and incorporate measures of bedrock mapping confidence.

Use Cases

• Generate mineral exploration targets based on machine learning-derived potential categories.
• Assess land-use planning scenarios based on maps containing bedrock mapping confidence measures.
• Identify anomalous stream sediment data for prospecting based on lithology-adjusted assay values.
• Evaluate mineral potential mapping methodologies based on described fuzzy logic buffer modifications.

Strengths

• Methodology incorporates an unsupervised machine learning algorithm to reduce human bias.
• Stream sediment anomaly detection method accounts for watershed lithology, improving robustness.
• Map legend and colour scheme have been revised for clarity and colour-blind accessibility.

Limitations

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