The Alaska-Premier is a silver, gold, copper, lead, and zinc 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 (Geology): Age = Lead-isotope studies of galena from the Alaska-Premier prospect (Maas and others, 1995, p. 254) indicate that the deposit is Jurassic in age, contemporaneous, at least in part, with island-arc volcanism in Hazelton time (Alldrick, 1993).
Comment (Workings): Workings / Exploration = Property was explored by open cuts and developed by more than 200 feet of underground workings, probably mostly in the 1920's. Selected samples of sulfide-rich quartz veins reportedly assayed as high as 35 oz Au per ton. Assays of some of the sheared and mineralized felsite showed about 0.097-0.145 oz Au and 1.0 oz Ag per ton.
Comment (Deposit): Model Name = Polymetallic veins
Comment (Reference): Primary Reference = Buddington, 1929
Comment (Deposit): Other Comments = Property probably originally staked in early 1920's. The Alaska-Premier site probably includes the old Ready Money and Alaska claims (Cobb, 1978, p. 92-93).
Comment (Geology): Geologic Description = The country rocks in the area of the Alaska-Premier prospect are pelitic metasedimentary and subordinate andesitic (greenstone) metavolcanic strata of the Jurassic or older Mesozoic Hazelton Group; the Triassic Texas Creek Granodiorite, which underlies and locally intrudes the Hazelton; the Eocene Boundary Granodiorite, which intrudes the Hazelton and Texas Creek rocks; and still-younger Tertiary lamprophyre dikes, which cut all the other rocks (Smith, 1973, 1977, Koch, 1996). The deposit (Buddington, 1925, p. 74, 78-79; 1929, p. 85-86) is in greenstone, slate, and graywacke country rocks. It consists of sulfide-bearing quartz veinlets in shattered zones in three sheets of altered 'felsite,' which may be either quartz porphyry sills or a facies of the greenstone. The veins contain pyrite, sphalerite, galena, pyrrhotite, and chalcopyrite; selected samples reportedly assayed as high as 35 oz Au per ton. A 3-foot thick mineralized shear zone in a felsite sheet contains disseminated(?) pyrite, galena, sphalerite, chalcopyrite, tetrahedrite, pyrrhotite, and arsenopyrite. Assays of some of the mineralized felsite showed about 0.097-0.145 oz Au and about 1.0 oz Ag per ton. Lead-isotope studies of galena from the Alaska-Premier prospect (Maas and others, 1995, p. 254) indicate that the deposit is Jurassic in age, contemporaneous, at least in part, with island-arc volcanism in Hazelton time (Alldrick, 1993).
Comment (Exploration): Status = Inactive
