Wolf Lake Project: Dorsey Terrane Geology and Mineralization Maps

A 2026 mapping project covers the northern half of the Jennings River (104O) and southern half of the Wolf Lake (105B) map areas. It describes polydeformed and metamorphosed rocks of the eastern Big Salmon Complex and Paleozoic assemblages of the Dorsey Terrane. The Government of Yukon produced this dataset, which details structural relationships and extensive stratabound pyrrhotite-sphalerite mineralization along a 6.5 km trend.

Use Cases

• Structural geological analysis based on described thrust relationships between Dorsey, Ram Creek, Klinkit, and Swift River assemblages
• Mineral exploration targeting based on the 6.5 km structural trend of stratabound pyrrhotite-sphalerite mineralization in calc-silicate rocks and rhyolite
• Regional geological mapping based on the polydeformed and metamorphosed rock descriptions of the eastern Big Salmon Complex and Dorsey Terrane
• Assessment of volcanogenic massive sulphide potential based on quartz +/- feldspar -phyric layers mentioned in the Dorsey and Ram Creek assemblages

Strengths

• Focuses on a specific 6.5 km structural trend of mineralization, providing a concrete spatial target
• Describes detailed structural relationships between multiple named rock assemblages (Dorsey, Ram Creek, Klinkit, Swift River)
• Identifies specific mineralization types (pyrrhotite-sphalerite) and host rocks (calc-silicate rocks and rhyolite)

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 bias inherent to the specific map areas (104O, 105B) covered
