Brown McDade Mine Geology and Mineralogy in Yukon

Yukon's Brown McDade Mine is a gold-silver discovery in an unglaciated area between Whitehorse and Dawson. The thesis details its geologic structure, mineralization, and hydrothermal alteration, with drilling data from 1946 indicating a 1000-foot ore length. The resource is a digitized thesis from the University of British Columbia.

Use Cases

• Analyze mineralization composition focusing on pyrite, arsenopyrite, and sphalerite to model gold-silver ratios.
• Study hydrothermal alteration patterns like sericitization and carbonatization in relation to the quartz feldspar porphyry body.
• Assess ore zone geometry using strike, dip, and width data from 1946 diamond drilling and stripping.

Strengths

• Contains specific geologic measurements, including a 1000-foot ore zone length and a 10-foot width.
• Provides detailed mineralogical inventory with over ten metallic minerals listed, including gold particle size (<150 microns).
• Includes comparative analysis classifying the deposit as a deeper epithermal type based on known deposits.

Limitations

• No structured tabular data or defined columns; information is embedded in narrative thesis text.
• Primary data is from a single historical investigation in 1946, limiting temporal scope.
• Spatial analysis is constrained to a single mine site without broader regional comparative data.
