Anabama Hill

概述

Best intersections of 1 to 3 m wide at 0.26 to 0.65% Cu and 0.6% Mo. There are greisen capped hills at Anabama and Netley. Extrusive equivalents may be rhyolites and rhyolite tuffs in the region. The granite is a biotite granite consisting of microcline, orthoclase, quartz, and biotite, although at Anabama Hill the rock is a biotite granodiorite with up to 15% biotite and some muscovite. The greisen is commonly brecciated. It is riddled with veins, pods, and bands of milky quartz. Beneath the greisen, the alteration consists of muscovite, chlorite, and epidote. The best rotary drill hole contained 67m at 1040 ppm Cu and 128 ppm Mo. There is only minor fracturing of the rocks.
