Mosaic Minerals Corporation announced the start of prospecting work for critical minerals on the Lichen project after several weeks of delay caused by forest fires. Covering 17,000 hectares (307 cells), the Lichen property is located approximately 100 km west of the Chibougamau mining camp. The property is underlain by volcanic rocks of the Obatogamau Formation cut by several stocks and plutons of immediate composition.

The volcanic rocks on the property are in contact with the Lichen pluton to the south in which pegmatites have been mapped. This geological environment is favorable to the presence of pegmatites both in volcanic rocks and in intrusive rocks.
