Location and accuracy Cobb (1972, MF-413), loc. 48; SW1/4 sec. 22, T. 3 N., R. 2 E., of the Fairbanks Meridian. The Perrault prospect is north of Fairbanks Creek and about 3/4 of a mile west of Too Much Gold Creek; it is at an elevation of 1,980 feet. Accuracy is within 1,500 feet.

Geologic setting

Geologic description

Gold is found in three or four nearly parallel veins of quartz enclosing masses of schist (Chapin, 1914, p. 329). Limonitic material taken from the dump is said to occur in veinlike bodies parallel to the quartz vein; it contains small amounts of both gold and silver (Chapin, 1914, p. 329). Narrow reticulating veinlets of stibnite occur in both quartz and schist, and yellow-green stains of antimony-oxide is abundant (Chapin, 1914, p. 329). The high grade portion of the shear zone was 2-feet-wide (Times Publishing Company, 1912, p. 22). The shear zone strikes N 80 W and dips 60 S. in quartz-mica schist (Chapin, 1914, p. 329).
The prospect was examined in 1942 as a possible source of antimony but did not exhibit sufficient antimony mineralization to warrant further exploration or development (Killeen and Mertie, 1951).

Production and reserves

Workings or exploration George Perrault located the Minnie and Aroostook claims and made a surface opening on a lode striking N 80 W that dipped 60 S. Chapin (1914) reported that these workings were caved by 1913.
Indication of production None

Additional comments

The prospect was discovered by George Perrault at some time prior to 1912 and consisted of the Minnie and Aroostook claims (Times Publishing Company, 1912; Chapman and Foster, 1969).
