Location and accuracy The location given is the approximate center of a northeast trending gold-bismuth anomaly that covers approximately one square mile on the east to northeast side of Coffee Dome; NW1/4 sec. 15, T. 3 N., R. 3 E., of the Fairbanks Meridian.

Geologic setting

Geologic description

Six reverse circulation holes were placed over a strong narrow, northeast trending gold-bismuth anomaly (Freeman and others, 1998). The holes were drilled near a 947 ppb and 1,337 ppb gold anomaly. Although altered upper plate rocks were encountered in all of the holes, assays returned only scattered intercepts ranging from 100 to 400 ppb Au.

Production and reserves

Workings or exploration Soil sampling and reverse circulation drilling examined a northeast trending gold-bismuth anomaly, but no substantial intercepts were encountered (Freeman and others, 1998).
