Soil Sampling At the Egnaty Creek Mercury Prospect, Kuskokwim River Basin, Alaska.
Augering, trenching, diamond drilling, and soil sampling were done on the Egnaty Creek mercury prospect to develop a method to delineate a potentially large low-grade mercury prospect in Cretaceous sandstones and graywacke. Augering was done with portable gasoline-powered augers; trenching was done with crawler- type tractors; spo-size core drilling was done with a portable diamond drill. Methods used in analyses of soil samples were the willemite screen, a commercial-type ultraviolet absorption mercury detector, and a vapor absorption method developed and used by the Geological Survey. Soil sampling, using the Geological Survey technique, promises to be a satisfactory method of delineating this prospect.
