Yukon Magnetic Geophysical Grids for NTS 105C

Aurora Geosciences Ltd processed 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 to produce four standardized gridded products. The dataset is provided by the Government of Yukon and was last updated in May 2026.

Use Cases

• Mineral exploration targeting based on processed magnetic field derivatives.
• Geological mapping and structural interpretation based on reduced-to-pole and tilt derivative grids.
• Integrating historical assessment data with regional compilations for a unified geophysical model.

Strengths

• Data integrated from multiple public assessment reports into standardized products.
• Includes four derivative grids (residual total magnetic field, reduced to pole, vertical derivative, tilt derivative) for analysis.
• Referenced against a published open file (YGS Open File 2017-11) for original data.

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 the source assessment reports.
