The most common and cost-effective source of lithium within the brine deposits are deep brines in continental sedimentary basins. Southern Manitoba has a complex groundwater aquifer system, with salinities ranging from brines in the deeper aquifers and brine springs to freshwater in the shallower and eastern aquifers. The brine springs occur along and near the shores of Lake Winnipegosis on large salt flats and have chemical signatures indicative of mixed halite dissolution brine and freshwater. Lithium concentrations in these brines range from 150 to 6300 ppb, with an average of 1263 ppb.
Summary(Plain Language Summary, not published)
Previous data collected as part of Groundwater Program studies of brine springs in central Manitoba were used to help Manitoba Geological Survey to assess the potential for Lithium resources in the province. Results show concentrations are less than required for typical exploration activities.
