Yukon Magnetic Geophysical Data Reprocessed for NTS 116I

Aurora Geosciences Ltd reprocessed publicly available digital magnetic geophysical data from assessment reports submitted prior to March 2015. The data were levelled and integrated with 1:250,000 scale compilations completed in 2017, producing two gridded PDFs for residual total magnetic field and reduced-to-pole data. Original 250k geophysical data is available in YGS Open File 2017-50.

Use Cases

• Conduct mineral exploration targeting based on processed magnetic anomaly maps.
• Integrate regional geological mapping with standardized magnetic compilations.
• Validate or supplement original assessment report data with levelled and gridded products.

Strengths

• Data integrated with standardized 1:250,000 scale compilations from 2017.
• Includes two specific processed products: residual total magnetic field and reduced-to-pole grids.

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 and temporal bias inherent to assessment reports submitted before March 2015.
