Geology

The Lion mine is on the east slope of Mount Benedict, on the north side of its main gulch. The principal openings are at 80 feet above the gulch at an elevation of about 4,050 feet. The mine is reported to have produced and shipped some ore. It is owned by George Norbeth, of Nogales, and is opened by shafts, cuts, winzes, and tunnels extending through a vertical range of 100 feet. The vein lies in the quartz monzonite country rock and dips steeply but variable to the north. It is 3½ feet in width and is composed mainly of quartz and crushed and altered quartz monzonite but contains considerable azurite, malachite, and bunches of galena, with which are associated gold and some silver. The deposit is being worked for its gold content. much of the ore is stained yellow with what is probably lead-copper sulphate.

The deposit probably owns its origin to a dark siliceous pyritic fine-grained, slightly porphyritic quartz diorite which occurs in intrusive masses and dikes just northeast of the mine.2
