Georgia Lake Project
Born from rock, built for energy – Our lithium mining project in Ontario
Our Georgia Lake lithium ore deposit is located in the Thunder Bay District, south of the town of Beardmore, with direct access to the Trans-Canada Highway, the national rail network, and the Port of Thunder Bay.
Rock Tech holds a strategic land position in the Georgia Lake area consisting 215 unpatented mining claims and 42 leases over a 5,686 ha land package. To date, only ~10% of the land position has been explored with potential upside across Georgia Lake’s 22 identified dikes.
While exploration at the Georgia Lake Project dates to the 1950s, Rock Tech began work in 2010 with phase exploration and has only explored ten percent of the area. Since 2021, Rock Tech has carried out more than 27,000 metres of drilling to support the Prefeasibility Study and update the mineral resources and reserve estimate.
Prefeasibility Study Highlights
The extracted ore will be concentrated on site
After extraction, the lithium ore (spodumene) is processed on site to increase its lithium content. To achieve this, the spodumene undergoes a concentration process comprising crushing, grinding, dense media separation (DMS), and flotation.
First, the ore is crushed and ground to liberate the spodumene-bearing minerals.
The material then passes through gravity separation plants, where waste rock is separated from the spodumene-rich fraction based on differences in density.
The remaining material undergoes flotation, during which reagents and air bubbles are used to selectively bind spodumene particles and separate them from residual impurities.
The concentration process yields a high-grade spodumene concentrate with a lithium oxide content of approximately six percent (SC6), which is required for refining into battery-grade lithium at the converter.
