The Crescent Lake Property comprises a block of 245 contiguous claims totaling 4908 ha, located near Armstrong Ontario.

The Crescent Lake property is located in the Seymour-Crescent-Falcon lithium belt, an area which is seeing recent exploration successes by ASX listed companies Green Technology Metals (GT1) and Battery Age Minerals (BM8).

The Seymour-Crescent-Falcon lithium trend is currently known to host thirteen spodumene-bearing pegmatites along a 26 km trend between the South Aubrey and the Falcon East pegmatite occurrences. Green Technology Metals has reported a Global Mineral Resource estimate of Global Resource of 9.9 Mt @ 1.04% Li2O on the Seymour project. GT1 has recently announced their plans for ongoing metallurgical work, planning for bulk sampling and pilot testing.

The Crescent Lake property covers an essentially unexplored 8 km section of this trend, which appears to be controlled by a deep-seated structure along a granite/volcanic contact. A limited channel sampling and diamond drilling program (totaling 849 metres) in 2016 tested four spodumene pegmatite bodies at the northeast end of this trend, generally at depths less than 35 metres vertical. All four pegmatites returned greater than 1% Li2O from surface and drill core sampling.

The highest recorded drilling intercept to date, was 1.17% Li2O along a 49 metre core length drilled down dip on the L61W areas East Pegmatite. Surface channels from the 2016 program returned up to 3.14% Li2O over 1.2 metres in the Chappais Pegmatite. Previous personnel reported spodumene crystals in the Chappais Pegmatite measuring up to 50 cm in length. A 4.0 metre wide section of the L61W areas East Pegmatite assayed 1.64% Li2O, 0.078% Ta2O5, 2270 ppm rubidium, 418 ppm caesium, and 256 ppm beryllium, from surface channel samples.

Over the remainder of 2023, Midex will focus exploration efforts on further delineating the existing known spodumene pegmatites and exploring for additional pegmatite occurrences.
