Location and accuracy NW1/4SW1/4 sec. 25, T. 3 N., R. 1 E., of the Fairbanks Meridian. The Newsboy Extension prospect is located 500 feet northeast of the Newsboy mine (ARDF no. LG100), just east of the Steese Highway, and about 1.3 miles northwest of Cleary Summit.

Geologic setting

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.

Production and reserves

Workings or 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.
Indication of production Undetermined
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).
