The Homburger (Newton Gulch) is a gold 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 (Exploration): Status = Probably inactive
Comment (Reference): Primary Reference = Mertie, 1918 (B 662-I, p. 425-449)
Comment (Geology): Geologic Description = About a dozen exploration shafts, some almost 100 feet deep, were dug on oxidized, limonite-stained, decomposed bedrock near a schist-marble contact in the headwaters of Newton Gulch (Smith, 1909; Mertie, 1918 [B 662-I, p. 425-449]). The deposit consists of pyrite in quartz stringers and as disseminations on the schist. Composite samples averaged about 0.25 ounce of gold per ton (Mertie, 1918; Cathcart, 1922). Bedrock in Newton Gulch is mostly amarble and schist, probably of early Paleozoic protolith age (Hummel, 1962 [MF 247]; Till and Dumoulin, 1994; Bundtzen and others, 1994). The marble-schist unit is in contact with another schist unit near this prospect.
Comment (Workings): Workings / Exploration = About a dozen shafts and at least 2 churn-drill holes had explored this prospect by 1918 (Mertie, 1918 [B 662-I, p. 425-449).
Comment (Deposit): Model Name = Low-sulfide Au-quartz veins (Cox and Singer, 1986; model 36a).
Comment (Geology): Age = Mid-Cretaceous or younger; veins cut schist metamorphosed in the mid-Cretaceous.
