Mineralization Comments

Jul 13, 2017 (C Ravnaas) - The ore minerals area petalite, cassiterite, ferrocolumbite, ferrotantalite, manganocolumbite, ferrotapiolite, microlite. The pegmatite contains abundant petalite, quartz, K-feldspar, plagioclase; accessory oxides (cassiterite, ferrocolumbite, ferrotantalite, manganocolumbite, ferrotapiolite, microlite, nigerite).


Jul 29, 2019 (Therese Pettigrew) - The School of Fish outcrop represents a boudinaged pegmatite swarm (Assessment report 52L07SE2003). DDH SR-17-71 returned assays of up to 1.978% Li2O, 0.581% Rb2O, 51.5 ppm Sc, 117.5 ppm Nb and 67.3 ppm Ta (Assessment report 20000015977).
