The metamorphic, structural and thermochronological evolution of the East Kootenay metallogenic province, southeastern British Columbia

Project code: 2017-009

Project type: Minerals and Mining

Proponent: University of Calgary, Alberta

Principal Investigator: Dr. David Pattison and Ms. Nicole Rioseco (MSc candidate)

Project location: East Kootenay Region, SE BC


Summary
This project will help reconstruct the geological evolution of the mineral-rich East Kootenay Region and determine if rock units containing garnet minerals might direct explorers to hidden mineralization.

The Need
The East Kootenay region of southeastern British Columbia hosts numerous rich mineral deposits, including the world-class Sullivan zinc, lead and silver deposit, and has potential to host many more. However, it is difficult to identify where to focus mineral exploration activities because there is an incomplete understanding of the complex rock units and their relationships to each other. A clearer understanding of the geological history of the area will highlight the region's mineral potential.

Project Goals
This project is designed to:

  • Look for clues in the rocks that reveal how deeply they were buried, what temperatures they reached, and how they were deformed, to provide information about the relationship between the Purcell Anticlinorium and the adjacent Kootenay Arc.
  • Establish the impact this burial and deformation had on the formation of mineralization in the East Kootenay region
  • Study the occurrences of rock units containing garnet minerals in the Purcell Anticlinorium and assess their role as indicators of mineralization
  • Stimulate on-the-ground exploration activities that could lead to new mineral discoveries.

Project Benefits
The new earth science information generated by this project will increase exploration efficiency by enabling smarter targeting based on a deeper understanding of the rocks and structures.

In addition to identifying mineral opportunities, the availability of new regional earth science data provides First Nations, regional districts, governments and local communities with a better understanding of the resources in their area leading to more informed land-use and resource management decisions.

Survey Area
The area of investigation for this project lies between Nelson in the northwest corner and Creston in the southeast, in the southern interior of British Columbia in an area known as the East Kootenays. Geologically, it is on the eastern limb of the Purcell Anticlinorium and the Kootenay Arc, both regionally-important structures associated with mineral deposits in the region.
