The SourceRock Li brine project covers a dominant land position of untested regional lithium brine targets within the Proterozoic Sibley sedimentary basin that is on a regional scale equivalent in size to Chile's Salar de Atacama central salt body, the largest Li brine-producing jurisdiction in the world. Not only do we have a large aerial coverage, SourceRock covers the deepest parts of the Basin with sedimentary thickness ranging from 500 m to 1,000 m, enhancing Li brine prospectivity. Exploration in the area has reported considerable evidence of supersaturated saline solutions within the Basin sediments and even the underlying Li-pegmatite-rich basement rocks. Halite (sodium, "Na") and sylvite (potassium, "K") veins, bedded layers, interstitial cements, and even encrustations on drill core and drill rods have all been mentioned in a variety of reports. Both Na and K are important pathfinders for Li within brine solutions, and higher concentrations of each of these elements supports the potential for higher concentrations of Li.
