Yukon Magnetic Geophysical Data Reprocessing for NTS 105L

Aurora Geosciences Ltd reprocessed publicly available digital magnetic geophysical data submitted with assessment reports prior to March 2015. The 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 derivatives.
• Geological mapping and structural interpretation based on reduced-to-pole magnetic data.
• Integrating historical assessment data with regional compilations for standardized analysis.

Strengths

• Data integrated with standardized 1:250,000 scale compilations.
• Four derivative products (PDF grids) provide multiple analytical perspectives.
• Original source data is documented in YGS Open File 2017-20.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Data freshness should be verified; the underlying assessment reports are from before March 2015.
