Location and accuracy This occurrence is on the east bank of Soluka Creek about nine miles above its mouth. It is at an elevation of under 300 feet in the NW1/4 sec. 28, R. 23 S., T. 34 W., of the Seward Meridian. The location is accurate within one-quarter mile.

Geologic setting

Geologic description

This occurrence is along the contact of a Tertiary pluton with Cretaceous sedimentary rocks and propylitically altered Tertiary volcanic rocks. The contact zone contains disseminated pyrite and radial quartz veins with pyrite and sphalerite (Church, Riehle, and Goldfarb, 1993). The occurrence is associated with a geochemical anomaly with 130 parts per million or more arsenic, 50 ppm or more cobalt, 500 ppm or more nickel, and 200 ppm or more zinc.
Geologic map unit (-154.860371943301, 58.1558058056152)
Mineral deposit model Polymetallic vein (Cox and Singer, 1986; model 22c).
Mineral deposit model number 22c
Age of mineralization Tertiary or younger; mineralization appears to be related to alteration zones adjacent to a Tertiary pluton.
Alteration of deposit The volcanic rocks are propylitically altered adjacent to the pluton.

Production and reserves

Workings or exploration Apparently only geochemical sampling by government geologists.
Indication of production None

Additional comments

The occurrence is in Katmai National Monument.
