Yukon Magnetic Geophysical Data Reprocessing for NTS 115K

Aurora Geosciences Ltd performed a review of publicly available digital magnetic geophysical data submitted with assessment reports prior to March 2015. The reprocessed data were levelled and integrated with 1:250,000 scale compilations. Four gridded PDF products were generated, including residual total magnetic field, reduced to pole, vertical derivative, and tilt derivative.

Use Cases

• Mineral exploration targeting based on processed magnetic field anomalies.
• Geological mapping and structural interpretation based on vertical and tilt derivative grids.
• Integrating historical assessment data with regional compilations for standardized analysis.

Strengths

• Data integrated with standardized 1:250,000 scale compilations.
• Four derivative products (residual, reduced to pole, vertical derivative, tilt derivative) provide multiple analytical views.
• Original source data is referenced to a specific open file (YGS Open File 2017-40).

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Data freshness should be verified as the underlying assessment reports are from before March 2015.
• Row count and specific data volume are unknown, which may limit suitability assessment.
