Snapshot	The Rainbow Lake is a world-class initial project. The Rainbow Lake area has the goal of targeting lithium production from oilfield brines in the Muskeg and Keg River formations. Brines will be treated using the Volt’s proprietary direct lithium extraction (DLE) technology (IES-300). After passing through the extraction process, the concentrated lithium brine stream will undergo further processing steps in order to produce commercial battery-grade lithium hydroxide monohydrate (LHM). As of January 31, 2024, Volt Lithium successfully produced 99.5% battery-grade lithium carbonate, a commercial and saleable lithium product, in-house at Volt’s permanent Demonstration Plant.

Summary:

Primary geologic targets of subsurface lithium enriched brines across the Rainbow Lake Lithium Project (RLP) area, are hosted within the Devonian aged Elk Point Group (Sulphur Point, Muskeg and Keg River Formations) of northwestern Alberta. The Elk Point Group aquifers are ideal candidates for sourcing subsurface lithium enriched brines for the purpose of Direct Lithium Extraction (DLE) due to their depositional and reservoir attributes. With a gross thickness exceeding 200 meters (m), and its overall expansive aerial extent, the Elk Point Group represents a known active aquifer system that has produced significant volumes of water associated with historical oil and gas production across the RLP area. Reservoir attributes associated with Elk Point Group primary lithology (e.g.,dolomite) provide significant pore volume and storage capacity of subsurface brines. In addition, high porosity and associated permeability values contribute to the ability of the aquifer to deliver significant production rates over a long period of time.

The Middle and Upper Keg River reefs formed on a carbonate platform created by the Lower Keg River Formation. They grew in small basins surrounded by carbonate shelves and the basins were later filled with Muskeg evaporites, which act as a seal for the traps. The Upper Elk Point Group carbonate strata within the Rainbow Lake Property area can be divided into four distinct paleogeographic regions: the Western Platform Edge/Slope (also known as the Comet Platform), Southern Basin, Northern Basin, and Eastern Platform Edge/Slope.
