Geologic setting

Geologic description

A shaft was sunk on stibnite-bearing breccia associated with a northeast-trending reverse fault that cuts schistose quartzite and mica schist (Chapman and Foster, 1969, p. D14). The vein trends N. 47 E., dipping 60 SE. (Pilkington and others, 1969). Stibnite occurs as lenses or nodules surrounded by sheared material. Channel samples across the vein range from 3.4 to 69.0 ppm gold with an average value of 16.1 ppm (Pilkington and others, 1969).

Production and reserves

Workings or exploration
A shaft of unknown depth was reported (Chapman and Foster, 1969).
In 2016, the Treasure Creek Partnership consolidated three, separately owned properties, including numerous prospects and occurrences (LG038; LG039; FB074; FB075; FB076; FB077; FB078; FB079; FB080; FB081) in the Treasure and Any Creek watersheds that potentially host plutonic-related, lode-gold mineralization contained in shear zones north of Fairbanks. Exploration activity in 2016 included conducting field work and reviewing and updating 1990s-era exploration information (Athey and Werdon, 2017).
