Locality 46-14 -- DARWIN MINE:

Location: 3.0 miles west-southwest of Smyrna, 0.5 miles south of Carroll and Ross (Mine)

Remarks: The mine was being worked during Lieber's survey in 1856. The vein, which contained considerable chalcopyrite as well as pyrite, averaged 3 to 4 feet in width. Ore was averaging 50 cents per bushel and occasionally coarse gold was seen. According to Sloan (1908), the mine is developed on several lenticular quartzose veins, varying from stringers to four feet in thickness. Average ore assayed $32.50; selected ore assayed $77.45 in gold per ton....

All the mines in this vicinity found two or more veins, generally less than 75 feet apart. At the Darwin, two veins a few feet apart have dips of less than 25 degrees to the northwest and southeast. Workings included an 85-foot shaft. Pyrite was found to be concentrated in streaks up to a foot thick; and vein minerals included native gold, chalcopyrite, calcite, and muscovite.

Workings at the mine include about 10 old shafts and the northenmost ones appear to be younger. A large trench exposes a quartz vein 15 feet thick, but containing few visible patches of sulfides.

In the cupiferous part of the Darwin Mine vein, numerous slate horses occur. The inconvenience resulting from being obliged to work a mine, where such wedges of the country abound, added to the greater difficulty of separating the gold from the pyritous ores, has caused this portion of the vein to be temporarily abandoned. The operations are at present (1858) confined to the more eastern parts of the vein, and, at that point, I am happy to say they are conducted with a good deal of energy and apparant success.

To me it was a source of no little gratification to find one gold mine still in activity--the first in a survey already extending over a period of two years, and covering six Districts. In the portion now worked the gold is occasionally seen in very coarse particles. The ore now probably averages about half a dollar per bushel.

The mine has latterly been worked for a number of years on a lease. Quite lately only, Messers. Black have sold out their interest to Mr. Nesbitt and others.

Locality 11-1-- Flint Hill (Old Darwin) Mine.

Location: 9.5 miles southeast of Gaffney, 1 mile east of Smith's Ford, Broad River.

Remarks: The mine was in operation at the time of Lieber's second survey (1858), and the ore averaged half a dollar a bushel. The northeast trending vein averaged 3-4 feet in thickness and contained massive chalcopyrite. Graton (1906) reported two 50-foot shafts and some pits, but the mine had been idle for many years. As much as $30,000 was said to have been taken from one shaft (Sloan, 1908). Two assays of white quartz gave about $4 per ton, while concentrated sulfides assayed $123 per ton. ....

Gold is present in a quartz vein 3 to 4 feet wide and at least 1700 feet long. The vein strikes N 67° E. The foot wall consists of mica schist and the hanging wall of a hard, grayish black mass of amphibolite, slightly impregnated with pyrite.
