| Location and accuracy | This occurrence is on the ridge on the north side of the upper Uranatina River about 1,000 feet west of elevation (peak) 5740. It is at an elevation of about 5,900 feet in the SW1/4 section 13, T. 5 S., R. 2 E., of the Copper River Meridian. This occurrence is probably located to within one-quarter mile; it is locality 80 of Winkler and others (1981 [OFR 80-892-B]). |
Geologic descriptionStratiform, iron-stained zones extend for as much as several hundred meters in quartz-mica schist of the Haley Creek terrane (Winkler and others, 1981 [OFR 80-892-B]; Winkler and others, 1981 [OFR 80-892-A]). These zones contain disseminated pyrite, sphalerite, and galena (?). These may be epigenetic replacement deposits and younger than the enclosing schist (Winkler and others, 1981 [OFR 80-892-B]). | |

| Mineral deposit model | Disseminated replacement deposits? in quartz-mica schist. |
| Age of mineralization | Schist of the Haley Creek terrane was probably metamorphosed in the mid-Cretaceous (Winkler and others, 1981 [OFR 80-892-A]). If the deposits are epigenetic, they are probably Late Cretaceous or Tertiary. |
| Workings or exploration | Surface examination and possibly sampling have taken place at this occurrence. |
