A Pb-Ag claim located next to the Great Silver claim & Mine.

A Ag-Pb-Cu-Au mine group located in the center & east-center of sec. 33, T.22S., R.16E. Owned
by Mumme Mining Co.

Mineralization is deeply oxidized, siliceous, lensing, quartz shear veins containing argentiferous galena and other sulfides, cutting crushed and altered Cretaceous andesite volcanics with interbedded silicated limestone and shale with rhyolite intrusives.

A strong siliceous vein or ore bed dips 30ºN. in andesite. It consists of an altered mineralizefd sheet of intrusive rhyolite from 2 to 3 feet thick, largely replaced by heavily iron-stained quartz and gypsum, which are the principal gangue minerals, especially next to the hanging wall. The ore mineral is dark, highly argentiferous galena.
