Oct 10, 2023 (Therese Pettigrew) - The Iris Lake exploration target was initially identified by the presence of garnet muscovite aplite (sodium-rich pegmatite) in the field. Sample 965154 returned 1070 ppm Rb, 169 ppm Be, 155 ppm Cs, 55 ppm Nb, 85 ppm Sn, and 87.3 ppm Ta from pegmatite/aplite. Sample 965217 returned 2030 ppm Rb, 212 ppm Be, 67.9 ppm Cs, 61 ppm Nb, 108 ppm sn, and 20.4 ppm Ta from a pegmatite boulder There were no significant Li assays (Tearlach Resources news release Oct 10, 2023).
