International Lithium Corp. announced that a drilling program currently underway at the Raleigh Lake lithium and rubidium project near Ignace, Ontario has intersected new spodumene pegmatite occurrences in the project's Zone 4 region which includes the historic Johnson pegmatite. ILC began an exploration drill program on August 3, 2023 to test targets defined by surface geological, geochemical and geophysical interpretations near Zone 1 and the recently defined mineral resource estimate area.

To date six drill holes have been completed (RL23-65 ­ RJ23-70) with two drill holes drilled immediately north of the Zone 1 mineral resource (RL23-65 and 66) and four drill holes further north, down dip and along strike of the outcropping Johnson pegmatite (now referred to as Zone 4). All drill holes except for RL23-69 intersected spodumene bearing pegmatites. The drilling within Zone 4 has intersected pegmatites over a strike length greater than 300 metres with true thicknesses approaching five metres.

The pegmatites correlate well with historic mapping of the Johnson pegmatite and historic drilling where the only hole drilled at the Johnson target intercepted a 3-metre interval of microcline pegmatite grading up to 0.466% Rb2O over 1.12 metres starting at 45.3 metres downhole depth. Several other samples from this historic hole returned highly anomalous rubidium assays. The Company believes that the Johnson pegmatite has the potential to become an additional rubidium resource as the microcline mineralization bears a close resemblance to that at Pegmatite 1. The presence of spodumene, also indicates that additional lithium resources might be delineated in Zone 4. Zone 4 was also historically targeted for tantalum mineralization and some columbite is thought to be observed in the recent drilling.

The Company intends to follow up with some additional down dip drilling at Zone 4 before moving on to other targets defined at depth in Zone 1 and possibly Zone 3.
