Jakes Corner Project: Airborne Geophysical Survey Maps from Yukon, 1994

2764 km of airborne geophysical survey data was collected over southwest Yukon Territory from March 12 to March 25, 1994. The dataset includes seven 1:50,000-scale maps covering NTS sheets 105 C/5, 12 and 105 D/8,9, produced for the Yukon Prospectors' Association. Maps include total field magnetics, electromagnetic anomalies, filtered VLF, calculated vertical gradient magnetics, and resistivity measurements at three frequencies.

Use Cases

• Prioritizing exploration targets based on electromagnetic anomaly maps
• Mapping subsurface resistivity variations using the 900 Hz, 7200 Hz, and 56,000 Hz coplanar resistivity maps
• Identifying magnetic structures using the total field magnetics and calculated vertical gradient magnetics maps
• Integrating geophysical data with geological information for target evaluation

Strengths

• Survey covers a defined area of 2764 km
• Includes seven distinct geophysical map types as described
• Data collection occurred over a specific 14-day period in March 1994

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/temporal bias inherent to the specific survey
