International Lithium Corp. (ILC) announced the start of Phase 3 of the 2022 diamond drilling campaign at the Raleigh Lake Lithium project near Ignace, Ontario, Canada. Further to Company's news release dated September 20, 2022; ILC has completed 6,251 metres core drilling at the Raleigh Lake project in the first two phases of drilling in 2022.

Phase 3 began on September 28, 2022 with approximately 2,500 metres of proposed drilling. The previous phase of drilling showed Lithium Oxide concentrations up to 3.62% over 6.46 metres and Rubidium Oxide up to a grade of 1.38% over 5.9 metres. Phase 3 will include continued exploration and infill drilling of Pegmatite 1 at Zone 1 and testing new exploration targets at Zone 5, Zone 3 and Zone 6, defined by lithogeochemical surveys in 2021.

The drilling objective at Zone 1 will be to trace the high-grade core of Pegmatite 1 up-dip, closer to surface, and investigate the possibility of additional pegmatites occurring below Pegmatite 1. Two holes have already been completed at the Zone 1 pegmatite occurrences with drill hole RL22-45 intersecting 14 metres of pegmatite (Pegmatite 1) starting at 84 metres downhole. The intersection includes 4 metres of monomineralic microcline from 85.5 - 89.5m. The microcline associated with Pegmatite 1 is known to contain highly anomalous rubidium concentrations and occurs in a distinct zone within Pegmatite 1 that could warrant declaring the rubidium in the upcoming resource estimate as a standalone commodity.

The second hole, RL22-46 was drilled approximately 75 metres west of RL22-45 and intersected Pegmatite 1 over 10 metres from 89 metres downhole. Here Pegmatite 1 was encountered roughly 15 metres deeper than modelling would suggest. A second spodumene bearing pegmatite was intersected from 108 - 110.5 metres downhole which aligns well with a deeper pegmatite vein encountered in drill hole RL22-27.

This new discovery will be followed up immediately in the next few drill holes. The drilling at Zone 1 continues to confirm the continuity of Pegmatite 1 and the near surface prospectivity for additional lithium and rubidium bearing mineralization. The narrow pegmatites intersected below Pegmatite 1 present an opportunity for the discovery of one or more pegmatites at depth which could be open to expansion in all directions.
