Mineralization Comments

Aug 27, 2019 (Therese Pettigrew) - Muscovite-bearing pegmatite dikes and small pegmatitic granite masses are widely exposed along Highway 11 at least between the Nym Lake road junction and west to Niobe Lake. Elevated rare-element contents were found in bulk coarse-grained green muscovite (up to 3 cm across) from the potassic pegmatite from sample 01-JBS-81-02. The muscovite contains 194 ppm Li, 2720 ppm Rb, 202 ppm Cs, 138 ppm Ta and 303 ppm Nb (Breaks et al., 2003).
