|Location and accuracy||The original reference for this occurrence only describes its location as being on the John River below the mouth of the Hunt Fork (Joesting, 1942). Based on subsequent descriptions (Berg and Cobb, 1967; Cobb, 1972; Maas, 1987), it may be at an elevation of about 1,500 feet on the east side of John River, about 1.5 miles downstream from the mouth of Hunt Fork. y Kurtak and others (2002) searched he area but they found no sign of this occurrence and there is no other evidence of its location other than the brief Joesting reference. The location of this occurrence is suspect.|
Geologic descriptionJoesting (1942) listed a stibnite lode, a sample of which assayed 42 percent antimony, on an unnamed tributary to the John River about a mile downstream from the mouth of the Hunt Ford. The rocks in the area consists of Upper Devonian, Hunt Fork Shale in fault contact with Middle or Upper Devonian(?) or older(?), black slate, phyllite. and limestone (Dillon and others, 1986). Kurtak and others (2002) searched the area for this occurrence but found no sign of it. The location of this occurrence is suspect.
