One of the prospects is located 2.75 miles (airline) and 3.0 miles via the Waynmanville Road, S. 35° E. of Thomaston. This prospect is 800 feet south of the road near the W. M. Dallas tenant house. About 300 feet west of the tenant house is an open field, a pit was dug for mica in 1942 by S. P. Cronheim. The pegmatite is three or four feet thick, consisting of coarsely crystallized pink feldspar, smoky quartz nodules, and numerous small books of rum-colored mica. No large quartz lenses are observed. The pegmatite is irregular in shape, lies nearly flat and is enclosed in biotite augen gneiss which is garnetiferous. Immediately southeast of the pit, the gneiss strikes N. 80° E. The pit at present is about 12 feet deep and exposes the complete thickness of the pegmatite. The mica is rum-colored, hard, flat, and splits well, but most of the books are small. Punch and some 1 1/2 by 2 inch sheet were obtained here, but not enough was found to justify the continuation of mining.
On the east side of the dwelling, due east of the above locality, a pit was made 15 feet deep. The pegmatite here tends to break up into stringers; it dips about 75° E. The mica is similar to that described above and is smaller than punch.
