Geology

The dumps of the Sherman and Pilfershire mines contain no radioactive rock. A small amount green fine-grained apatite is present in some of the Pilfershire ore, but the most abundant gangue mineral is feldspar. According to Kemp (1908, p. 71), the ore and the geologic features of the Pilfershire mine are very much like those at the Cheever mine. The maximum radioactivity measurement on the dump was 0.04 mr per hr. The Sherman mine has been considered (Kemp, 1908, p. 88) the northern extension of the Smith mine ore body. On the basis of radioactivity, however, this does not seem probable, because the maximum radioactivity measured on the dump of the Sherman mine was only 0.03 mr per hr whereas pieces of ore in the dump of the Smith mine measured as much as 0.17 mr per hr. A grab sample (FK3-39) of the ore from the Sherman mine contains 0.001 percent equivalent uranium. (McKeown and Klemic (1956))
