Lithology

Lithology Comments

Aug 13, 2014 (N Bennett) - The hole drilled through 39m of overburden until it intersected quartz gabbro up to 85.06m. Mineralization occurs as pyrite and chalcopyrite mineralized quartz veins at 83.49m near the bottom of the unit. Evidence of this being the bottom of the pulse is the sharp contact of the quartz gabbro and chill zone in the quartz gabbro with the bordering amphibole pyroxenite of pulse 3. The third pulse lower down contains mineralized amphibole pyroxenite with basal mineralization from 86.86 to 103.46m. . Below the amphibole pyroxenite is quartz gabbro that represents the crustally contaminated bottom of this pulse from 103.46 to 143.50m. The unit contains brecciated xenoliths of amphibole pyroxenite, from the underlying unit, starting at 105.46m and all the way to the bottom of the pulse at 143.50m. The gabbro is consistently brecciated and xenolith-rich to 143.50m. The second pulse observed in the hole contains amphibole pyroxenite that is brecciated with pyrrhotite-chalcopyrite mineralization starting at 149 to the bottom of the unit/pulse at 168m. At the bottom of the amphibole pyroxenite, the unit contains phenocrysts of feldspar from 168.09 to 168.62m which is interpreted to be assimilation of the underlying unit/first pulse. The hole then intersects a quartz diorite (possible roof unit to first pulse) followed by the main quartz gabbro from 186.83 to the end of the hole at 200m.
