Identification information

Deposit ID 10094104
MRDS ID A106215
Record type Site
Current site name Homesteader-Martha

Geographic coordinates

Geographic coordinates: -149.30269, 61.79956 (WGS84)
Relative position Best location from Cobb (1979) is the NW 1/4 of the Anchorage 1:250,000-scale topographic map. The original reference provided no data on the exact location of the prospect. Latitude and longitude coordinates provided are a generalized location, representing the NW1/4 of the Anchorage 1:250,000-scale topographic map. Prospect probably occurs in the Anchorage D-6 or D-7 1:63,360-scale map.

Comments on the geologic information

  • Geologic Description = Details about the prospect are unavailable. Most likely, a gold-bearing quartz vein(s) cuts the Late Cretaceous Willow Creek Pluton. The Willow Creek Pluton is a zoned pluton. The outer part consists of hornblende quartz diorite and lesser hornblende tonalite; the core consists of hornblende-biotite granodiorite, and lesser hornblende-biotite quartz monzodiorite and biotite quartz monzonite.
  • Age = Late Cretaceous or younger; the host of mineralization is the Late Cretaceous Willow Creek Pluton.
  • Age = Host rock is Late Cretaceous.
