A mica mine on the property of Dr. C. W. Dean three-eighths of a mile southwest of Hiram is owned by H. G. House, of that town. Pegmatite is exposed in the bed of Copper Mine Creek at the site of the old Dean mill. The deposit was worked prior to 1914, and the mine was operated on a large scale by Dr. George Eagsdale in 1919 and 1920. A slumped open-cut 100 ft long and 50 ft wide is said to have been 40 ft deep. Some pits and shafts are in a line that extends 200 ft northeast of the cut.
The pegmatite body is 50 ft in outcrop breadth and trends N. 25° E. It consists of a medium-grained quartz-feldspar rock, coarse pink perthite, and pods of milky quartz. Southwest of the main cut it terminates in a large quartz mass that is 75 to 100 ft in breadth. Greenish "A" mica is associated with the quartz, and brownish-olive mica occurs in the medium-grained feldspathic pegmatite. The books are large and abundant but are heavily spotted. Several carloads of mica are said to have been shipped from the mine.
