Location and accuracy The Nadina River site is a discredited placer location for gold and platinum group metals. In about 1899, the entire creek was staked from Nadina Glacier to the stream's confluence with the Copper River but there is no record of actual production or the occurrence of significant gold or platinum-group elements. The arbitrary location given here is in the wide glacial valley on the border between the Gulkana and Valdez quadrangles.

Geologic setting

Geologic description

Most of the wash in the Nadina River is unaltered andesitic lava and tuff of the Mt. Drum volcano (Mendenhall and Schrader, 1903, p. 63-64). As early as 1899, there were rumors of very high grade gold and platinum in the sediments of Nadina River. The river was staked and intensively prospected; one shaft was reportedly 67 feet deep. The Geological Survey collected many samples from the area but was unable to confirm any concentration of gold or platinum metals, and there has been no further reports of placers along the river.

Age of mineralization Probably no placers exist but if so, they would be Holocene.

Production and reserves

Workings or exploration The creek was actively prospecting beginning in about 1899, but apparently with no results and there is no indication of any activity after about 1903. One shaft was reportedly 67 feet deep.
