Yukon-wide mineral potential mapping was last conducted 18 years ago, necessitating updated maps for land use planning. The Yukon Geological Survey developed a new GIS-based hybrid methodology combining probabilistic and fuzzy logic approaches. The method generates maps with prospectivity and confidence scores for each spatial block, based on categorical features and weighted evidential layers.
Use Cases
- Assessing regional mineral resource potential for land use planning based on the prospectivity and confidence scores.
- Comparing mineral potential across different geological structures using the leveled data methodology.
- Integrating claim and assessment report footprint data into mineral system analysis as described in the methodology.
Strengths
- Methodology is explicitly described as a hybrid between data-driven probabilistic and expert-driven fuzzy logic approaches.
- Output includes both a mineral potential score and a bedrock mapping confidence score for each spatial block.
- The process accounts for major structural displacements by evaluating and stitching areas separately.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
- Freshness should be verified; the last updated date is 2026-04-17.
