As you know no rock gets left unturned, here are a few facts on the Bernic Lake pegmatite (Tanco deposit) ... we know these numbers constituted a world-class deposit and profitable mine. Mineralogy (as defined in the late 60s): 1. A wall zone containing microline, quartz, beryl and some tourmaline (ranges from 1-50 feet thick). 2. A spodumene zone containing spodumene, feldspars, quartz, and muscovite (ranges from 15-50 feet thick). Recoverable ore was estimated at 4.7 million t of 2% Li over 22 feet. 3. A lepidolite zone which replaces part of the microline-quartz zone with rubidium disseminated throughout. There were about 100,000 t @ 2.2% Li oxide in three areas. 4. A pollucite zone with 3 sheet-like formations - the largest was up to 45 feet thick (300,000 t @ 20.4% cesium). 5. A tantalum zone with quartz microline assemblage containing tantalite and beryl, a pure quartz core unit, and an aplitic assemblage containing tantalite (1.9 million t @ 0.16% Ta2O5 + 536,000 t @ 0.24% Ta2O5) It is interesting to note that the Tanco pegmatite does not outcrop anywhere in the area, the only outcrop is under Bernic Lake. Good to see someone is reading these posts. DRT
