Location:
Grass River - Thompson Nickel Belt, parts of 63O1, 8 and 63P12
Project Description
Main objectives:
To trace the extent of Paint Lake group supracrustal rocks along the eastern margin of the Thompson Nickel Belt. Continue to gather information about the sequence and its petrogenesis and attempt to differentiate these rocks from highly metamorphosed Ospwagan Group rocks.
Methodology:
- 1:20 000 scale bedrock mapping of islands, shoreline, and ridgelines proximal to the Grass River;
- Isotopic, mineralogical, and geochemical characterization of various units.
Benefits:
Updated 1:20 000 geological maps will provide a better geological understanding of the eastern TNB. The project will hopefully improve the ability to discern Ospwagan Group rocks from the Paint Lake sequence. New exposures of Ospwagan Group stratigraphy towards the east could expand the area currently being explored for nickel in the TNB.
