Geologic information

Identification information

Deposit ID 10000891
MRDS ID A011545
Record type Site
Current site name Mount Goldie

Geographic coordinates

Geographic coordinates: -150.84281, 62.72955 (WGS84)
Relative position Coordinates given here locate one of the two anomalous stream sediment sites described as the Mt. Goldie anomaly by Clark and Hawley (1968, Figure 2, no. 56). They report that the anomaly encompasses an area in Sections 31 and 32, T. 31 N., R. 8 W. and Sections 7 and 8, T. 30 N., R.8 W., of the Seward Meridian. The area lies within Denali National Park and Preserve.

Comments on the geologic information

  • Geologic Description = Clark and Hawley (1968) describe the Mount Goldie silt anomaly as underlain by Mesozoic graywacke, quartzite and argillite (KJs) that are cut by Tertiary(?) aplite dikes and auriferous quartz veins. One rusty-weathering dike, about 3 feet wide, contains pyrite and arsenopyrite with minor gold. The aplite dikes may be related to the early Tertiary Kahiltna pluton (Tmk, Reed and Nelson, 1980) about four miles to the northwest. Two stream silt samples from streams draining this area contained 0.2 and 0.3 ppm gold, respectively (Clark and Hawley, 1968, Figure 2, no. 56). ? Stream sediment samples with elevated Au, As, Be, Co, Cu, Cr, Nb, Pb, Sn, and Zn values from four streams in the area between the Tokositna and Kahiltna Glaciers indicate the area is auriferous and could host mineralized prospects (Clark and Hawley, 1968). See Rocky Cummins (TL016).
  • Age = Tertiary; mineralization is interpreted to be linked to the Kahiltna pluton (Tmk), part of the McKinley Sequence, that has been determined to range from 52.3 to 56.2 m.y. in age by K/Ar method (Reed and Lanphere, 1972; Reed and Nelson, 1980).
  • Age = Chron age is for McKinley Sequence.

Comments on the workings information

  • Workings / Exploration = Reconnaissance mapping, stream silt and rock sampling are all that have been done here. Two stream sediment samples from drainages in this area contained 0.2 and 0.3 ppm gold, respectively (Clark and Hawley,1968).
