South Wopmay Bedrock Mapping Project and Integrated Studies
The project is located ~250 km north of the city of Yellowknife, Northwest Territories, between Great Slave and Great Bear lakes and between the Tlicho communities of Gameti and Wekweeti. The area straddles the boundary between the Archean Slave Structural Province in the east and the Phanerozoic Interior Platform in the west.
An updated consistent and cohesive bedrock geological map of the southern Wopmay orogen fills in one of the last remaining bedrock knowledge gaps in the region and assists in the understanding of, and relationships between, the geological evolution and polymetallic mineralization preserved in the study area and adjacent areas.
The South Wopmay Project is an initiative of the NWT Geological Survey that combines traditional bedrock mapping with targeted investigations, such as metallogenic, isotopic, and geophysical studies. Bedrock mapping is conducted on foot by traverses up to 15 km, and assisted by use of zodiac boat, helicopter, and fixed wing aircraft to access remote locations.
Bedrock mapping focused in two corridors as Phase I and Phase II of the project. Fieldwork for Phase I was initiated in 2004 and completed in 2007; Phase II got underway in the summer of 2008 and was completed in 2012. The project has produced new maps, multiple journal publications and other products. Publication of a final digital atlas is anticipated in 2019.
