The 301 (Doctor's, Kolb, Farrar) mine, on lot 301 in the fifteenth district, near Holly Springs, is controlled by a group of Atlanta businessmen. When visited it was being worked under the supervision of W. H. Fluker. The mine is opened by a shaft about 143 feet deep, from which two levels have been driven at depths at 80 and 140 feet. A short tunnel, several old stopes, and some other old workings were partly accessible.

The country rock near the lode is a mica schist. About 100 feet southeast of the main workings is a few feet of interlayered mica schist and dark-green amphibole gneiss, and lighter-colored feldspathic amphibole gneiss crops out farther to the southeast. The foliation planes in the schist and gneiss strike N. 40° to 50° E. and dip 65° to 75° SE. Few exposures of solid rock are to be found except in the mine workings and in some road cuts, the surface being nearly everywhere covered with soil and saprolite.

The lode consists of numerous quartz layers and stringers, generally parallel to the foliation of the country rock. Near the collar of the shaft 15 quartz layers, each less than an inch thick, occur within a width of 28 inches. The number of quartz layers changes abruptly, and in places they are nearly absent. The rock adjoining them and forming part of the lode consists mainly of fine grained quartz and sericite. A little pyrite and chalcopyrite are usually present; the gold is said to be in the pyrite. The sulfides are almost completely oxidized on the 80-foot level, but the rock in the lower (140-foot) level appears fresh.

Only a little exploration work had been done in depth up to the time of the visit, 1934-35, and the results were not encouraging. The property is said to have been core drilled, but the results were not available.
