Comments on the site names

  • Names listed as "previous" are misleading. This record may be a conglomeration of all the named properties which seem to be a combination of veins, adits, and claims.

General comments

Subject category Comment text
General Anna Wilson suggests deleting this record IF (or after) each individually named mine/deposit is represented by its own record. This is a group record and, as such, is relatively unhelpful. The name Great American is not found in PP-223, PP-94. It is mentioned in Bull. 1208 (page 9, last line) only as a synonym for Big Chief adit.
