Location and accuracy Locality is about 4 km northeast of the mouth of Currant Creek and includes the unnamed tributaries of Currant Creek. This is locality 26 of Nelson and others (1985) and locality 28 of MacKevett and Holloway (1977). Sec. 26, T. 3 N., R. 27 W., of the Seward Meridian. Accurate to within 1,600 meters, the occurence may extend up to 2.5 km downstream from the plotted point.

Geologic setting

Geologic description

Mineralization is in form of disseminations and fracture fillings of pyrite and chalcopyrite in strongly iron-stained intermediate volcanics and in the neighboring hypabyssal granitic to granodioritic intrusives near contact of Tertiary granitic rocks and Tertiary volcanic rocks. Interpreted by Resource Associates of Alaska (1976) as a volcanic neck or breccia pipe, composed of highly fractured, silicified, and recrystallized volcanic rocks. Resource Associates of Alaska (1976) reported a nearby stream sediment sample with value of 1,200 ppm Cu.
