Quarry

The Quarry is a lead, barium-barite, fluorine-fluorite, zinc, and silver 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 (Reference): Primary Reference = Herreid, 1970

Comment (Deposit): Model Name = Stratabound replacement lode of quartz-fluorite-barite with associated galena and sphalerite.

Comment (Geology): Geologic Description = The Quarry prospect is in the contact zone of marble and underlying schist; the marble unit is probably part of the massive marble unit of Bundtzen and others (1994) the main minerals are quartz, fluorite, and barite that replace the marble. They occur with disseminated to semimassive pods of galena, sphalerite and boulangerite. Galena and sphalerite also occur as disseminations in aragonite and calcite veins. The occurrence is nearly stratabound, but cross-cutting replacement fronts of ankerite, partly oxidized to limonite, flank the mineral deposits. A large lead and zinc soil anomaly, about 2000 by 6000 feet and elongated northwesterly along the marble-schist contact, is developed over the prospect. Grab samples contained as much as 0.02 ounce gold per ton and 5.30 ounces silver per ton (Herried, 1970).? Fluid inclusion studies (Brobst and others, 1971) show that mineralization was fairly high temperature (near 250 degrees F). The abundance of fluorite and slightly anomalous amounts of elements such as beryllium led Brobst and others (1971) to suggest a Late Cretaceous age of mineralization, similar to the fluorite-rich tin deposits of the northwestern Seward Peninsula.? Herreid (1970) interpreted the mineralization as being associated with a thrust at the base of the marble unit. In general, most of the relations are also consistent with mineralization controlled by shearing between two units of differing competency. The prospect is on strike with, and in a similar structural and stratigraphic setting to, the Galena prospect (NM135) about 2 miles to the northwest.

Comment (Geology): Age = Probably Late Cretaceous; post regional metamorphism.

Comment (Exploration): Status = Probably inactive

Comment (Workings): Workings / Exploration = Some workings on the property appear to have been done about the time of World War I (Herreid, 1966, 1970). The prospect was probably re-exposed when work was done on a rock quarry for the Nome-Teller road. Fluorite-rich samples were collected by Mulligan and Hess (1965), probably from old workings. Heiner and Porter (1972) reported claim activity by Foster in 1966. The claims were later taken over by W. Hoogendorn and associates. The deposit was examined in the 1990's by Kennecott Exploration Company and by Cominco Exploration. A caved shaft probably dates from the earliest exploration.
