Project Description

Main objectives:

The purpose of this project is to highlight Manitoba’s lithium potential which can attract new exploration companies to the province.

The objectives of this project are to:

  1. Compile the already known lithium assets in Manitoba (e.g. Li-bearing pegmatites),
  2. Identify new potential lithium targets in Precambrian rocks, and
  3. Investigate the potential for deep Phanerozoic lithium brines in the Williston Basin.

Methodology:

  • Review and compile all historic occurrences of lithium in pegmatites and deep brines.
  • Field site visits in areas of active lithium exploration, including Far Resources’ Zoro1 property, Wekusko Lake; Ashburton’s Violet-Thompson/Thompson Bros pegmatite, Wekusko Lake; and Tanco mine, Bernic Lake.
  • Compile historical water and chemical analyses from petroleum technical wells files and groundwater data.
  • Sample and conduct geochemical analyses on brines from brine springs and well heads (tentative).

 

Benefits:

This project will investigate the lithium potential of the province and provide much needed information on the various lithium occurrences in Manitoba in both Precambrian rocks and deep Phanerozoic brines. This will create new exploration targets and attract junior companies interested in this emerging and high-demand commodity.

 

Plans for fiscal year 2019-2020:

  • Continuing collaboration with Western University on a MSc. thesis project: test pegmatite drillcore in systematic intervals using a Raman spectrometer to obtain a better resolution data set; electron microprobe and laser-ablation work in micas, as required.
  • Contribution to Report of Activities focused on the tectonic framework of the lithium-bearing pegmatites of the Wekusko Lake pegmatite field.
