Comments on the geologic information

  • Geologic Description = Anikovik River's eastern tributaries have headwaters in Ordovician limestone of the York Mountains (Sinsbury, 1972) whereas the main drainage and western tributaries are in areas underlain by a thin-bedded, slaty metapelitic and metasandstone sequence of unknown but probable Paleozoic age locally intruded by altered mafic bodies . This locality is in the lower part of the river within 0.25 miles of the Bering Sea. The geomorphic character of this area suggests that at least some alluvial deposits of the Anikovik River have been reworked by shoreline processes but available descriptions are insufficient to evaluate this possibility. The two USBM churn-drill holes here (Mulligan, 1959), encountered only 3 and 4 feet of gravel and appear to have been in alluvial materials. A trace of tin was found in the heavy mineral concentrates from these churn-drill holes but the identified minerals only included pyrite, limonite pseudomorphs after pyrite, augite, ilmenite, magnetite, ankerite, and zircon (Mulligan, 1959, p. 19). Mulligan (1959, p. 5) reports that a small dredge worked in this area for 123 days during the 1914 and 1915 seasons. This dredge processed 156,000 cubic yards of gravel and recovered 1,217 ounces of gold and 1,600 pounds of concentrate containing 31% tin.

Comments on the workings information

  • Workings / Exploration = Mulligan (1959, p. 5) reports that a small dredge worked in this area for 123 days during the 1914 and 1915 seasons. This dredge processed 156,000 cubic yards of gravel and recovered 1,217 onces of crude gold and 1,600 pounds of concentrate containing 31% tin. Two USBM churn-drill holes were later completed in this area (Mulligan, 1959).
