The Dome View 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 (Deposit): Model Name = Polymetallic vein (Cox and Singer, 1986; model 22c).
Comment (Workings): Workings / Exploration = The Dome View prospect contains exploration pits and two adits, Dome View #1 and Dome View #2. The adits were caved by 1986 (Fairbanks Exploration Inc., unpublished report, 1986). Dome View #2 is about 1,000 feet southwest of Dome View #1.
Comment (Geology): Geologic Description = The quartz mica schist which makes up the country rock at this prospect trends N 60 E and dips 15 to 20 SE. Diorite of the Pedro Dome intrusive crops out a short distance south of the adit. The prospect was accessed by a 145-foot-long adit on a shear zone striking N 40 E and dipping 70 NW. The shear zone ranges from 12 to 40 inches wide and averages 30 inches. It is composed of crushed and brecciated white quartz in the hanging wall and more massive white quartz in the footwall. Samples collected from the margins of the shear contained from $0.38 to $3.26 per ton in gold (0.02 to 0.15 ounces of gold per ton) but do not represent the higher grade portion of the shear which was unsafe to sample (Hill, 1933). Approximately 1,300 tons of ore was extracted from the adit which was estimated to contain $5 per ton in gold (0.24 ounces of gold per ton). A second tunnel, known as the Dome View #2, was driven on a shear about 1,000 feet southwest of the Dome View #1 adit. The Dome View #2 was thought to be the same shear as exposed in the Dome View #1 adit; however, the Dome View #2 shear dips in the opposite direction and probably represents a different shear zone. ? the prospect was mapped and sampled in 1933 by Spencer and O'Neill (1934) who reported that a shaft sunk near the Dome View #2 adit had exposed arsenopyrite- and pyrite-rich quartz containing a little free milling gold. Spencer and O'Neill (1934) attributed the formation of the Dome View prospect to the Pedro Dome intrusive body. Scorodite and iron oxide are common in brecciated quartz from the Dome View prospect. Two samples collected at 18 and 30 feet from the Dome View #1 portal averaged 0.10 and 0.12 ounces of gold per ton, over 18 and 24 inches, respectively. A grab sample of quartz-rich material from this adit's dump returned 0.32 ounces of gold per ton A dump sample from the Dome View #2 shaft contained 1.94 ounces of gold per ton from material containing 30 to 40% sulfides. The shear at the Dome View #2 shaft trends N 85 E and dips 70 SW. Two samples collected from the dump of the Dome View #2 shaft in 1969 contained greater than 150 ppm gold.? the prospect was examined in 1986 by Fairbanks Exploration Inc. (Fairbanks Exploration Inc., unpublished report, 1986). Exploration pits and at least two caved adits on the prospect expose bedrock similar to those at the Newsboy mine; however felsic schist apparently constitutes a smaller portion of the rock section in the vicinity of the Dome View prospect. The predominant alteration present in samples collected on the prospect was stockwork silicification accompanied by hematite after pyrite, and scorodite after arsenopyrite (Fairbanks Exploration Inc., unpublished report, 1986). Despite the lack of intense alteration, gold values ranged up to 6100 ppb and were accompanied by anomalous silver, antimony and arsenic. No work has been conducted on this prospect since 1986.
