The Hendrickson is a gold and antimony 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 (Geology): Age = Mid-Cretaceous or younger; vein cross cuts schist metamorphosed during the mid-Cretaceous.
Comment (Exploration): Status = Active?
Comment (Deposit): Model Name = Low-sulfide Au-quartz veins (Cox and Singer, 1986; model 36a).
Comment (Reference): Primary Reference = Cathcart, 1922
Comment (Workings): Workings / Exploration = This prospect was explored by a 150-foot adit that was partially caved by 1916 (Cathcart, 1922). In 1916, the total length of underground workings on lode gold prospects in Anvil Creek valley was several hundred feet (Mertie, 1918).
Comment (Geology): Geologic Description = The Hendrickson prospect is within or near the Anvil Creek fault and related shear zones that are as much as 120 feet wide. The deposit consists of quartz-calcite veins that contain arsenopyrite, pyrite, and locally stibnite. The veins commonly cut schist or are localized in shear zones (Collier and others, 1908; Brooks, 1916; Mertie, 1918 [B 662-I, p. 425-449]; Cathcart, 1922). Pyrite and arsenopyrite also are disseminated in schist peripheral to veins and sulfide-rich zones as much as 15 feet wide are known. Vein samples from this prospect contained a little more than 0.5 ounce of gold per ton (Cathcart, 1922, p. 238). The Anvil Creek fault is a high-angle structure that juxtaposes different types of graphitic schist and dark graphitic quartzite in this area (Hummel, 1962 [MF 247]). Bedrock is mostly graphitic schist, probably of early Paleozoic protolith age (Hummel, 1962 [MF 247]; Sainsbury, Hummel, and Hudson, 1972 [OFR 72-326]; Till and Dumoulin, 1994; Bundtzen and others, 1994).
