Lithology Comments

Aug 07, 2012 (A Wilson) - Three separate quarry faces mark the operation of this property. The blasted faces to the northeast of the lake are broken along silvery muscovite planes separated by 1.5 to 8 cm of quartzose rock. An adjacent and lithologically similar pit contains muscovite of a faintly green variation which is concentrated on foliation/bedding planes striking 150° and dipping 40° southwest. The granular quartz exhibits a reddish tinge, perhaps an alteration effect from the inclusive Ilmenite specks found throughout. The third and major quarry face is operated in two tiers found 25 msouthwest of the above mentioned faces and adjacent to the north shore of Threetails Lake. Both faces extend 20 m along a strike of 172° , paralleling the green micaceous planes in the gneissic rock. The northerly tier measures 18 m high. There is a dip of 50° west on both faces. In conjunction with reddish quartzite, and micaceous layers at 8 cm intervals, this rock also contains ilmenite banding, traces of microscopic garnet inclusions and quartz vein intrusions along structurally incompetent micaceous zones. Sillimanite was noted adjacent to biotite lamellae.
