The Newsboy Extension 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 = Gold-quartz vein.
Comment (Geology): Geologic Description = The shear zone at the Newsboy Extension shear trends N 15 E and dips 77 NW, whereas the Newsboy shear (described in Newsboy mine, ARDF no. LG100) strikes N 40 E and dips 73 NW (Smith, 1913; B 525). The ore is similar in character to that from the Newsboy mine but contains less free quartz. Considerable development work was completed on the Newsboy extension in 1911 (Brooks, 1912). The mine was worked from a 115-foot deep shaft with short production drifts at the 60-foot level. The ore was reported to average about $15 per ton in free milling gold (0.72 ounces of gold per ton) (Smith, 1913; B 525). The mine was inactive and the shaft flooded by 1913 (Chapin, 1914). Hill (1933) indicated that the prospect had been idle for 20 years and none of the workings were accessible.
Comment (Workings): Workings / Exploration = Considerable development work was completed on the Newsboy extension in 1911 (Brooks, 1912). The mine was worked from a 115 foot deep shaft with short production drifts at the 60 foot level. The mine was inactive and the shaft flooded by 1913 (Chapin, 1914). Hill (1933) indicated that the prospect had been idle for 20 years and none of the workings were accessible.
Comment (Exploration): Status = Inactive
Comment (Reference): Primary Reference = Smith, 1913 (B 525)
Comment (Production): Production Notes = By late 1911, the prospect was leased by Mr. McGillivray and Mr. Fisher who erected an 8-ton-per-day, 5-stamp mill which was connected to the hoist house during the winter of 1911-1912 (Times Publishing Company, 1912; Smith, 1913; B 525). The mine was worked from a 115 foot deep shaft with short production drifts at the 60 foot level. The ore was reported to average about $15 per ton in free milling gold (0.72 ounces of gold per ton, Smith, 1913; B 525).
