Superimposing the resistivity low found by the Company’s 2016 MagnetoTelluric (MT) survey on the seismic section (see Figure 2 below) revealed a significant broadening of the low within the fault zone. The Company believes that the bulk of the resistivity low is associated with salty water occurring within the lithium-bearing claystones to the west. Any permeable beds in or adjacent to the fault zones are lithium brine targets. However, because lithium brines are heavier than fresher, more recent waters, the best targets are deeper.

At Clayton Valley, 75 km (47 miles) north of Bonnie Claire (see Figure 3 below), lithium brines occur in permeable beds adjacent to a major north-south fault. The north-south fault brings neutral pH water into the valley and the water leaches lithium from lithium-rich sediments and produces lithium brine (Source: Pure Energy Clayton Valley PEA, 2017). The Company believes that the same process may occur at Bonnie Claire where a major north-south fault zone intersects lithium-rich claystone. If the fault brings neutral pH waters into contact with high pH lithium-rich sediments, leaching could create lithium brine. Clayton valley, currently operated by Albemarle, is the only producing lithium brine deposit in North America and has been operating since 1966 (57 years).

The Company anticipates a 1,350 to 1,500 meter (4,400-5,000 ft) vertical hole would be necessary to test this brine target and is developing a plan to drill it in 2024. This drilling would run concurrently with the continued development of the sedimentary lithium resource which is currently advancing towards a prefeasibility study.
