Identification information

Deposit ID 10308243
Record type Site
Current site name Unnamed (at head of Goat Hollow)

Geographic coordinates

Geographic coordinates: -135.86212, 59.44975 (WGS84)
Relative position This occurrence is at an elevation of approximately 5,400 feet on the ridge at the head of the Goat Hollow drainage. It is about 3.7 miles, N20E from the village of Klukwan in the NE1/4, section 15, T. 28 S., R. 56 E. of the Copper River Meridian. It is in the approximate center of a line of samples, numbers 766 to 771, shown on sheet 2 of Gilbert and others (1991) and is included within the area of number 29 on sheet 1 of Still and others (1991).

Comments on the geologic information

  • Geologic Description = Still and others (1991) informally refer to this as the 'Goat Hollow' occurrence. They collected a sample from a chalcopyrite-bornite lens about 0.5 feet in width that contained 15.052 ppm gold, 54.2 ppm silver and, 21.8% copper. Other bedrock and float samples collected at this locality contained up to 0.72 ppm gold, 4.1 ppm silver, and 1.2% copper (samples F103 to F105 of sheet 1 and samples 766 to 771 of sheet 2 of Gilbert and others, 1991). Sample descriptions by Gilbert and others (1991) include foliated diorite and pyroxenite, diorite, monzodiorite, and ultramafic rock with feldspar veinlets. In the area of the anomalous samples, Gilbert and others (1987) have mapped a steep fault that strikes northwesterly and separates Cretaceous diorite and quartz diorite to the southwest from Cretaceous monzodiorite and quartz monzodiorite to the northeast. They consider the monzodiorite and quartz monzodiorite to be part of the compositionally zoned, Kashagnak pluton of Redman and others (1984), but believe the diorite and quartz diorite are older. It is unclear if the mineralization is related to the faulting or to a particular intrusive rock unit. If the deposit is related to the intrusives, the mineralization is Cretaceous or younger in age.
  • Age = If the deposit is related to intrusive rocks, the mineralization is Cretaceous or younger in age.
