Geologic information

Identification information

Deposit ID 10002208
MRDS ID A013109
Record type Site
Current site name Hayes

Geographic coordinates

Geographic coordinates: -135.45208, 59.04975 (WGS84)
Relative position This occurrence is near the southeast corner of section 35, T. 32 S., R. 59 E, of the Copper River Meridian. It is at an elevation of about 1,600 feet about 0.2 miles southeast of hill '2015'. The location is from pages 3 and 4 of Herbert and Race (1965) and is considered accurate. This location apparently corresponds to location 9 in Cobb (1972 [MF 424] which is located, probably less accurately, approximately 0.5 miles to the southeast.

Comments on the geologic information

  • Geologic Description = The following description is summarized from Herbert and Race, 1965. Rocks in the area are metasediments, including marble and gneiss, that strike northwesterly; there is also some east-west faulting. The prospect is located on a steep cliff at the head of a talus slope that contains float of magnetite in marble and chalcopyrite with hematite in an impure schistose marble that has been partially altered to skarn. The deposit is considered to be low-grade mineralization in metamorphic rocks close to an east-west fault. Only stream sediment sample values are reported. Copper values in the vicinity of the prospect do not exceed 90 ppm copper, but 3 samples to the south varied between 120 and 130 ppm copper. The age of the mineralization is not well established, but is probably Cretaceous based on the age of the nearby intrusive rocks (Gilbert , 1988).
  • Age = The age is not well established but the deposit is probably Cretaceous based on the age of nearby intrusive rocks (Gilbert , 1988).
