Busby

The Busby is a silver and lead mine located in Alaska.

About the MRDS Data:

All mine locations were obtained from the USGS Mineral Resources Data System. The locations and other information in this database have not been verified for accuracy. It should be assumed that all mines are on private property.

Mine Info

Satelite View

MRDS mine locations are often very general, and in some cases are incorrect. Some mine remains have been covered or removed by modern industrial activity or by development of things like housing. The satellite view offers a quick glimpse as to whether the MRDS location corresponds to visible mine remains.

Comments

Comment (Production): Production Notes = Approximately 12 tons of ore assaying 44.4 ounces of silver per ton and 48.1 percent lead was shipped to the American Smelting & Refining Company, at Helena, Montana, in the spring of 1973 (Conwell, 1973).

Comment (Reference): Primary Reference = Conwell, 1973

Comment (Exploration): Status = Inactive

Comment (Workings): Workings / Exploration = High-grade lead-silver ore was hand-sorted from a shallow trench (Conwell, 1973). Approximately 12 tons of ore assaying 44.4 ounces of silver per ton and 48.1 percent lead was shipped to the American Smelting and Refining Company, at Helena, Montana, in the spring of 1973. Approximately 130 feet of trenching along the vein has exposed a well-defined fracture containing galena. Two additional veins containing high-grade galena diverge from the main fracture at an acute angle.

Comment (Deposit): Model Name = Schist-hosted galena vein

Comment (Geology): Geologic Description = The following description of the Busby mine is taken from Conwell (1973). The rock at the mine is the Mystic Creek Member of the Totalanika Schist, which consists of black schist with interbedded limestone. Galena-bearing veins crosscut the black schist and are nearly vertical. A well-defined vein containing galena is exposed along a trench about 130 feet long. Two additional veins containing high-grade galena diverge from the main vein at an acute angle. Assays indicate that the ore has about 1 ounce of silver for each 1 percent of lead. In addition to the galena-bearing fractures, there is a prominent altered zone; samples from this zone are not of ore grade, but they are anomalously high in silver and lead. High-grade lead-silver ore was hand-sorted from a shallow trench. Approximately 12 tons of ore assaying 44.4 ounces of silver per ton and 48.1 percent lead was shipped to the American Smelting and Refining Company, at Helena, Montana, in the spring of 1973.
