|Location and accuracy||This prospect is on the south bank of Beaver Creek. It is at an elevation of about 3,300 feet in the SW1/4 of section 8, T. 2 N., R. 24 E. of the Copper River Meridian. This is locality 187 of MacKevett (1976) and it is included in National Park Service localities WRST-176A and WRST-275 (unpublished data). Cobb and MacKevett (1980) included this prospect under the name 'Wiley'. The location is accurate within about 1,000 feet.|
Geologic descriptionThe deposit at this prospect consists of a small massive sulfide body that contains pyrrhotite with minor chalcopyrite, arsenopyrite, and gold; it is surrounded by surficial materials (Moffit and Knopf, 1910; Knaebel, 1970; MacKevett, 1976). Bedrock in the area is Jurassic or Cretaceous siliciclastic rocks; about a mile to the north, they are intruded by Cretaceous granitic rocks and about a mile to the south by Tertiary gabbro (MacKevett, 1978). The deposit was explored by a short adit.
