Geologic information

Identification information

Deposit ID 10307300
Record type Site
Current site name Milroy Creek

Geographic coordinates

Geographic coordinates: -163.30341, 65.89936 (WGS84)
Relative position Milroy Creek is a north tributary to Hannum Creek (BN056 and BN057). A locality on this creek was not included by Cobb (1972; MF 417) but Cobb (1975; OFR 75-429; 1981; OFR 81-363A, p. A15) does make reference to it. This locality could be anywhere along Milroy Creek and therefore cannot be located to closer than a few miles.

Comments on the geologic information

  • Geologic Description = Anderson (1947, p. 31) reports that heavy mineral concentrates from Milroy Creek gravels are similar to those from Cunningham Creek (BN113) which contain galena, lead carbonates, and pyromorphite. The Harrys Creek (BN055) and Hannum Creek (BN056) galena-bearing lode deposits are sources of lead minerals in gravels downstream from them. The presence of placer gold has not been specifically reported (Cobb, 1981; OFR 81-363A).
  • Age = Quaternary
