Location and accuracy | This occurrence is at the mouth of Left Fork, a west tributary to Kougarok River. It is 2.5 miles west of the Nome-Taylor road and about a 1,000 feet west of the mouth of Louisa Creek, a small east tributary to Kougarok River. This is locality 3 of Gamble (1988). |
Geologic descriptionGamble (1988) describes this occurrence as disseminated chalcopyrite in chlorite schist and reports one per cent copper and 15 ppm silver from one sample. Bedrock exposed in the area around the mouth of Left Fork is part of a mafic metavolcanic assemblage that Till and others (1986) consider to be Ordovician in age. | |
