Identification information

Deposit ID 10001980
MRDS ID A012824
Record type Site
Current site name Dakota

Geographic coordinates

Geographic coordinates: -165.50745, 64.64761 (WGS84)
Relative position The Dakota prospect is probably on the north side of Boulder Creek about a quarter of a mile below its confluence withTwin Mountain Creek (shown as Twin Mtn Ck on the map) which joins it from the north. Mertie (1918 [B 662-I, p. 425-449]) reported a 35-foot-long adit driven into marble on the Dakota claim, one of a group of 13 claims in this area at the time. The location is accurate to within about 1,000 feet. Information for this prospect was summarized by Cobb (1978 [OFR 78-93]) under the name 'Dakota'.

Comments on the geologic information

  • Geologic Description = The location is at a bold outcrop of marble about a quarter mile below Twin Mountain Creek (shown as Ttwin Mtn Ck on the map) on the north side of Boulder Creek. At this site, a short adit is driven into apparently barren marble. Strongly ankeritized rock is evident nearby in placer tailings. A few small quartz veins that strike north-northeast occur in the bluffs on the south side of Boulder Creek, opposite the short adit. Mertie (1918 [B 662-I, p. 425-449]) reported a 35-foot-long adit and quartz-calcite veins in marble with practically no sulfides at the Dakota prospect. Alaska claim files (Heiner and Porter, 1972,Kardex site Kx 52-105) list 16 Dakota claims staked for gold, antimony, and tungsten by W. Cochrane in about 1900. It is possible that better mineralization was exposed but is now buried by placer tailings. Gold-bearing bedrock mineralization (NM167) was found on the bench north of the Dakota prospect by Kennecott Exploration Company in 1992 and 1993.
