Radioactivity investigations in the Serpentine-Kougarok area, Seward Peninsula, Alaska, 1946

NANA Geothermal Assessment Program Final Report

“…An intricate network of faults southeast of the granite is associated with major geochemical anomalies and mineralized areas lying along a NW-trending fault zone (Sainsbury and others, 1980). The Serpentine hot springs granite contains small amounts of radioactive material disseminated throughout; however not in large enough quantities to be commercially interesting (Moxham and West, 1953). Based on temperature data alone, these springs appear be suitable for Chena-type power generation, though the salinity of the fluids could be an issue in terms of scaling in wells and pipes.…”

“…Knopf (1908a) confirmed the presence of placer cassiterite on Humbolt Creek. Moxham and West (1953) visited the area in search of deposits of radioactive minerals, Sainsbury, Kachadoorian, Smith, and Todd (1968) described placer concentrates containing cassiterite from Humbolt Creek, and Sainsbury, Hudson, Kachadoorian, and Richards (1970) provided a preliminary description of the geology and the results of a more detailed investigation of mineralized areas. Some data on the thermal springs in the area were included in a report by Miller, Barnes, and Patton (1975).…”

“…The presence of cassiterite in placers was first reported by Collier (1904b, p. 28) and later confirmed by Knopf (1908ba, p. 63). Moxham and West (1953) outlined the occurrence of mineralization, lode prospects, and placer deposits in the Serpentine-Kougarok area and summarized the results of investigations for radioactive minerals in this area. Sainsbury, Kachadoorian, Smith, and Todd (1968) presented data on the nature of cassiterite in the gold placers of Humbolt Creek and suggested nearby areas favorable for lode deposits of tin.…”

Placer deposits of Alaska

“…In 1946, Moxham and West (1953) investigated the headwater area of Hot Springs Creek (62, fig. 19) for radioactive minerals.…”
