The Smucker is a silver, lead, zinc, and copper 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.

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 (Exploration): Status = Active
Comment (Deposit): Other Comments = Excellent example of stratiform volcanogenic sulfide deposit typical of the Ambler sequence in the southern Brooks Range. This is the westernmost known occurrence of this type deposit in the southern Brooks Range. All available data suggest Smucker to be relatively significant in size (Hitzman and others, 1986)
Comment (Deposit): Model Name = Kuroko
Comment (Workings): Workings / Exploration = Surface geologic mapping, geochemical sampling (soil grids), electromagnetic measurements, magnetometer measurements, and eight drill holes by 1984 (Nana Development Corp., written commun., 1997). According to Mayfield and Grybeck (1978) two drill samples 2400 ft (820 m) apart intersected layered sulfide zones 9 ft. to 27 ft. (3 m to 9 m) thick assaying 100 g/ton Ag, 2-8% Zn and 1-1.6% Pb. Grades from drill samples indicated 3.8% Zn, 1.2 to 1.6% Pb, 69-514 g/ton Ag. ???
Comment (Geology): Geologic Description = Layered sulfide zone 9 ft to 27 ft. (3 m to 9 m) thick, continous for at least 6000 ft (2000 m) along strike, consists of banded, fine to medium grained pyrite, sphalerite, galena, chalcopyrite and minor owyheeite in a silica-calcite-pyrite matrix. The country rocks are characteristic of the Devonian-Mississippian Ambler sequence and consist dominantly of well-foliated porphyroblastic quartz-feldspar-muscovite-chlorite schist interlayered with quartz-muscovite-chlorite phyllite, graphitic phyllite, calcite-mica schist and marble. Mineralized zone is repeated by complex folding (Nana Development Corp., written commun., 1997)
Comment (Reserve-Resource): Reserves = Hitzman and others (1986) report greater than eight million metric tons grading 0.8% Cu, 6.8% Zn, 2.3% Pb, 200 g/ton Ag. Bundzten (1995) reported "significant" tonnage grading 1.5% Pb, 5%-10% Zn, 103-343 g/ton Ag, and minor Au.
Comment (Reference): Primary Reference = Hitzman and others, 1986
Comment (Geology): Age = Devonian
