Deposit ID 10000423
MRDS ID A010590
Record type Site
Current site name Fairview

Geographic coordinates

Geographic coordinates: -149.28364, 59.89452 (WGS84)
Relative position The occurrence is located on the Resurrection Peninsula about 1.7 miles north of Cape Resurrection on the southwest flank of Hill 2077. The main showing is about three quarters of a mile east of the shore along a cliff in the NE1/4 of section 28, T. 3 S., R. 1 E., of the Seward Meridian. At the base of the cliff, there is a 8 to 10 feet thick breccia zone that strikes N78E and dips vertically. Higher up and about 300 feet to the east another similar zone (possibly the same one faulted a little to the north) is 8 to 10 feet thick. This is location 6 of Cobb and Tysdal (1980) and location 109 in Tysdal (1978). This location is accurate within a quarter of a mile.

Comments on the geologic information

  • Geologic Description = Tysdal and Case (1979) described the bedrock geology in this area as Cretaceous, pale to dark green, aphanitic to porphyritic pillow basalt with subordinate pillow breccia, tuff, and siltstone. ? the mineralization is hosted in a breccia that is fractured and recemented with quartz and sulfides, the breccia cement is soft and weathers to a gossen, although the sulfides are not evenly distributed through the cement. One zone 6 foot wide is particularly rich in sulfides. A sample of this material assayed 9.8% copper (Martin and others, 1915).
  • Age = Cretaceous.

Comments on the workings information

  • Workings / Exploration = One short, 10 foot adit was driven prior to 1918. The adit was driven in a 6 foot wide breccia zone where the cement was rich in sulfides. A sample of this richly mineralized zone assayed 9.8% Cu (Martin and others, 1915).
