Reconnaissance Sampling of Beach and River Mouth Deposits, Norton Bay and Kotzebue Sound, Seward Peninsula, Alaska.
Deposits along the shores of the Seward Peninsula, Alaska were sampled by the federal Bureau of Mines during August 1959. The reconnaissance included sampling between: 1) Golovia and Koyuk on the south shore of the Seward Peninsula, and 2) between the Goodhope River and Alder Creek on the north shore of the peninsula. Bench deposits were sampled to indicate their heavy mineral content and to determine if detailed studies on individual deposits would be warranted. Stream and river deposits were sampled and analyzed for indications of lode deposits which may exist inland from the beach areas. The samples were shipped to the Bureau of Mines laboratory at Juneau for analysis. Of 61 samples analyzed petrographically, 10 were bedrock chip samples and 51 were pan concentrates of beach and river deposits. Only trace quantities of heavy minerals were recovered from all deposits by single pans. Traces of tin were detected in two samples from the shores of Norton Bay. Travel within the areas examined was by small boat; bedrock formations cropping out along the shore were examined when time, weather, and beaching conditions permitted. No deposits of potential economic value were found.
