The area slopes to the north and is extensively covered by tundra and permafrost loess that increases in thickness to the west. The deep frozen loess and colluvium prevents soil sampling particularly at lower elevations and inhibits the expression of mobile metals derived from underlying residual bedrock. Soil cover along Line 6 was found to be slightly thinner and samples from Line 6 collected by hand auger generally contain 15 to 60 ppb gold, which are judged to be anomalous due to the thickness of surficial cover. Localized magnetic anomalies from the ground survey, with magnitudes as much as 170 gamma, appear to define the contact of the Fairbanks schist with the underlying carbonate and mafic schist unit.
