A former Au occurrence/mine located in sec. 27, T26N, R21W, G&SRM, 4.5 km (2.8 miles) N of Mount Perkins (coordinates of record), less than 2 miles South of the Mocking Bird Mine, 13 miles SE of Nelson's Landing, and about 23 miles NW of Chloride, on Bureau of Land Management administered land.
The Hall mine, which works the most northerly of the veins, is developed principally by a 210-foot shaft and two levels, containing about 200 feet of drifts. The vein ranges in thickness from a few inches to 2 feet, and is locally associated with diabase dikes. The gangue is quartz, some being of the honeycomb variety. Some of the ore is very rich, shows free gold, and is said to contain values of $10,000 or more to the ton. A 24-ton mill is operated at the mine.
The Hall vein is a few inches to 2 feet wide and consists of honey-combed quartz hosted in granite. The ore body dips N at a width of 0.61 meter wide. Associated rocks include Pliocene-Neoproterozoic dolerite. Local rocks include Early Proterozoic metamorphic rocks.
Workings include underground openings with a length of 301.75 meters and an overall depth of 64.01 meters. The mine was developed to the 200 foot level before 1908. In 1907 a 24 ton/day mill was in operation.
