Reference information

Comments 5-m intercept at 0.1% Cu, 4 m at 0.1% Mo. Location from Morris (1979); according to Singer and others (2008) best rotary drill intercept was 67 m at 1040 ppm Cu and 128 ppm Mo, and best drill core was 1 to 3 m at 0.26 to 0.65% Cu, 0.6% Mo. Veins, breccia in biotite granite with minor muscovite; Greisen that caps Anabama Hill is brecciated. It contains pods and bands of milky quartz. Altered rocks beneath greisen, contain muscovite, chlorite and epidote; fracturing is minor. Ore area 2.5 square km, alteration A axis 1.0 km, alteration B axis 0.5 km.
