Deposit ID 10003584
MRDS ID A106342
Record type Site
Current site name Rex Creek, North Fork

Geographic coordinates

Geographic coordinates: -155.8025, 57.59935 (WGS84)
Relative position This site represents lode claims indicated on U.S. Bureau of mines maps in 1973 (MacKevett and Holloway 1977 locality 11; Church and others, 1989, MF 1539 I, locality 6 ). These references indicate that the claims are on the south fork rather than the north fork of Rex Creek. The locality is therefore suspect and can only be considered accurate to within several miles.
