Apr 20, 2016 (Therese Pettigrew) - The Caral pegmatite is located about a mile north of Palace Lake, close to and west of Piper Lake. It strikes about N35E and dips 80NW. It has been traced in outcrops and in the drillholes for a length of about 700 feet. At or near its southwest extremity it is only about 2 feet wide; but it increases gradually in thickness to the northeast, where it averages about 10 feet in width over a length of 400 feet. Spodumene can be observed in the surface exposures, where it occurs as fine-grained prismatic crystals, 0.5-1 inch in length, crudely oriented roughly normal to the strike. Midway along the dike this spodumene is unaltered, but to the southwest, as a large sheet-like body of diabase is approached, it becomes highly sericitized. It is not abundant (Pye, 1965). A grab sample collected by Caral Mines in 1955 assayed 2.55% Li2O (Selway et al., 2012).
