Report: Morning Glory The Morning Glory is near the western end of the highly productive Comet-Gray Eagle shear zone. Although alteration products are primary kaolinite and siderite rather than quartz, sericite, and pyrite, suggesting a low grade vein (Pinckney, 1965), the Morning Glory was quite productive. From 1920-1957, the mine produced 19,231 tons of ore yielding 2,484 oz Au, 268,054 oz Ag, 4,138 lbs Cu, 83,140 lbs Pb, and 7,793 lbs Zn. Four parallel N62W 80-84NE veins with ore shoots up to 100 feet long and 5 feet wide occupy an east-west shear zone (Roby and others, 1960; Becraft and others, 1963). The veins contain quartz, chalcedony, galena, sphalerite, siderite, and calcite. The abundant carbonates were associated with low metal values, while the ore was composed of plentiful galena and sphalerite (Becraft and others, 1963). The large mine dumps representing thousands of feet of workings through 3 caved adits and 1 caved shaft are composed entirely of unaltered quartz monzonite and quartz monzonite with kaolinite and siderite alteration products. Because of this benign mineralogy, even though they impinge on Cataract Creek the dumps do not appear to contribute to the degradation of the creek. During the 1930's (Roby and others, 1960), a flotation mill operated at the site. Today there are approximately 6,000 tons of tailings on the banks of Cataract Creek with high silver values (JJMG-1) of 1.64 oz/ton and low base metal values (see map). Radiation is also slightly anomalous.
