First Class Metals PLC announced that is has signed a sixty day exclusivity agreement with Emerald Geological Services Limited ("EGS") in respect of an earn into the McInnes Lake Property ("McInnes Lake") in NW Ontario. Underexplored greenstone belt in the North Caribou Terrane of the Superior Province. No previously known gold occurrences until 2021.

Field programs in 2021 and 2023 identified 6 new gold occurrences >100 ppb up to 3.6 g/t Gold ("Au") on the current claims Anomalous lithium ("Li") in volcanic host rocks up to 1,200 ppm Li in boulders and 984 ppm Li in outcrop discovered in 2021 and 2023 field programs. Three pegmatite dykes previously identified by the Ontario Geological Survey ("OGS"), related to McInnes Lake Pluton, a fertile peraluminous granite body. The three pegmatite dykes were investigated and sampled in 2023. Lithium values up to 354 ppm from bulk samples of pegmatite; rubidium ("Rb") and caesium ("Cs") values up to 2,750 ppm and 413 ppm respectively from samples of blocky k-feldspar.

Up to 984 ppm Li, 649 ppm Rb and 216 ppm Cs from adjacent volcanic host rocks. Pegmatite exposures are up to approximately 40m wide with mapped strikes of up to 190m. Pegmatite and anomalous lithium (up to 501 ppm Li) in volcanics discovered further north of the previously identified pegmatites in 2023; system now has 700-meter strike length and is open along strike.
