Between the old mining reports and perusing LIDAR, I had identified possible locations for nine old mines/prospects. I found the first seven, but ran out of time before visiting the other two. 1 - Eph Lee Mine In 1915 it was reported that "this is a mine older than most of those in the district. The workings consist of an irregular shaped pit from which a 40 ft. tunnel has been driven." In 1942, "the works consisted of a partly filled conical shaped hole 20 ft. in diameter and about 10 ft. deep. There are two outlet trenches, one 20 ft. long striking NE; another 15 ft. long strikes SW." As with many of these old mines, the descriptions from over 100 years ago bear little resemblence to what is seen today. Many tunnels were opened up by large cuts, while others caved in, in subsequent years. |

A book of Mica, about 3/4 inch thick, in quartz. It might contain 20-100 individual mica sheets, depending on plate thickness. Seen in one of the Eph Lee Mine waste piles. |

2 - Ward Gap Mine This mine was worked in 1907 and 1908 by J. L. Ingram for the Pitner Mica Mining Co. It was mainly an irregular open pit with a crooked incline extending into the south wall. |

3 - Two Locust Gap Prospects Two parallel trenches, about 100 ft. apart, are located here; dug about 1906. The works had been long abandoned by 1940 and do not appear to have been extensive. Mica from the two prospects was reported to have been similar. |

You can see where the prospectors cut out the pegmatite between the rock ledges on either side here. |

4 - The Green Vein In 1915, a series of 3 hillside pits, one above the other, uncovered an irregular, vertical dike varying in width from 1 to 5 feet. When seen in 1923, this mine was opened by a cut 20 feet deep and 40 feet back into the mountain-side. After 100 years, it is now a series of partly- filled pits connected by a wide trench running down the steep slope of the ridge. The mica was greenish in thicker books, giving the mine its name. |

5 - The Ward Prospect Work here was done by T. J. Stevenson, of Dahlonega, in September, 1942. The prospect consisted of an "L-shaped" open cut driven through the pegmatite, and of a 15-foot drift. The open cut was from 8-10 ft. wide but narrowed to 6 ft. at the head of the drift. The cut is noticeably larger at present and there is no sign of the drift. |

6 - The T.H. McDonald Prospect This opening was made on a steep wooded slope about 300 ft above the road. A considerable amount of mica, mostly scrap, was obtained from this opening about 15 feet deep which was made in 1942. All of the books contain a dark stain arranged in a pattern to produce the effect of grating when examined by transmitted light. The pattern produced in this mica is described from some other mines in Fannin & Cherokee Co's, where it is termed "house roof" by the miners. |
