Report: Mountain Lion The Mountain Lion is near and similar to the Moonlight. According to Emmons and Calkins (1913), $3,000 worth of silver-lead ore was produced from a steeply southeast-dipping, northeast striking sheeted zone in Quadrant quartzite. The ore appears to be a quartzite breccia cemented by quartz and iron oxides; a composite sample of this mineralized rock on the dump sample 0.010 oz/ton Au, 2.34 oz/ton Ag, 0.049% Cu, 0.303% Pb, and 0.053% Zn. A discharge issues from the caved adit, but it sinks almost immediately into the dump. Most of the dump is unaltered quartzite that has been disturbed by bulldozers, so volume estimates cannot be obtained. A few hundred tons of oxidized mineralized breccia (represented by the composite sample described above) is also present.
