Project Description

Main objectives:

This project aims to gather new Precambrian and Quaternary geoscience data along the East Side Road extending from Manigotagan to Bloodvein, and further toward Berens River depending on road status.

Methodology:

Reconnaissance mapping of Precambrian outcrops, including new roadside exposures and inland traverses, will be carried out at locations selected mostly using satellite imagery. Results will be supplemented with new U-Pb geochronology, Sm-Nd analyses, and geochemistry. Quaternary investigations including ice-flow mapping and till sampling will be carried out in the same region.

 

Benefits:

New road cuts provide excellent sites for geological survey investigations. Highway access significantly increases economic feasibility of even small mineral operations, including granite slab quarries that can be identified partly on the basis of fracture density. The southern part of the road also transects the western part of the Rice Lake belt, with several historical gold mines. New geological information gathered along the East Side Road may support community land-use planning, particularly by the First Nations communities of Hollow Water, Bloodvein, and Berens River.

 

Plans for fiscal year 2020–2021:

  • Conduct Precambrian reconnaissance mapping and Quaternary studies along ~130 km of road, including loop traverses and side roads

  • Submit key samples for various analyses (bedrock geochemistry, U-Pb geochronology, Sm-Nd analyses, till geochemistry, KIM analyses, thin section petrography)  

  • Summarize results in Report of Activities 2020
