post from BrineboysAll the available data below bodes well for an extremely high recovery and lower end capex costs via DMS as fine grains are more expensive to separate. 1.5pct plus Li20, coarse(better) spodumene , crystal size (bigger the better)and iron content (lower the better) play pivotal roles. The iron content is expected to be fairly low as the spodumene are white and green in color. The lighter the color the lower the iron content. Crystals average 3-7 cm. In the very coarse zone... Spodumene crystals are fewer in number but may be 50 cm long and 5-7 cm in diameter. In the quartz core, grain size is in excess of 5 cm and is composed of mainly quartz with feldspar and spodumene. Spodumene crystals are up to 90 cm in length. : The spodumene in the North Dyke is very coarse-grained with blades up to 5 by 70 cm. The spodumene in the Main Dyke is abundant, very coarse-grained and green to white in colour. Tantalum mineralization is abundant in the Main Dyke and the North Dyke.
