Gold occurs in numerous localities throughout the State, generally in quartz veins of the gneissic, granitic and dioritic rocks, also in those of the talcose, chloritic and argillaceous slates, and in beds of the slates themselves, and in gravel deposits, the debris of the decomposed rocks and veins. The principal counties in which it has been found in sufficient quantity for exploitation are: Franklin, Nash, Granville, Alamance, Chatham, Moore, Guilford, Davidson, Randolph, Montgomery, Stanly, Union, Cabarrus, Rowan, Mecklenburg, Lincoln, Gaston, Catawba, Caldwell, Burke, McDowell, Rutherford, Polk, Cleveland, Cherokee, Jackson, Transylvania and Watauga. It is generally more or less alloyed with silver, varying from pure gold on the one side to pure silver on the other. Near the surface it is usually associated with limonite and at a greater depth of the deposits with pyrite, chalcopyrite, galenite, zincblende, tetradymite, arsenopyrite. rarely with altaite and nagyagite. Specimens of gold, remarkable for their size, have been found at the Reid Mine, in Cabarrus county, the Crump Mine and the Swift Island Mine, in Montgomery county, (at the latter place in plates, covered with octahedral crystals), at the Cansler & Shuford Mine, in Gaston county, and the Little John Mine, in Caldwell county, and Pax Hill in Burke county. Very beautiful arborescent gold has been obtained from the Shemwell vein in Rutherford county.
