Geologic information

Identification information

Deposit ID 10008742
MRDS ID D001110
Record type Site
Current site name Cold Spring Mine
Alternate or previous names Cold Sping (note the misspelling)

Comments on the site names

  • Colo Metal Mining Fund Board book p. 21 says that Cold Spring No. 4 is the Pick and Gad. PP-245 (pl. 18 says that Cold Spring No. 3 is the Pick and Gad.
  • Mines mentioned as being previous names in a combined record for Cold Spring that do not appear to have individual entries include (note some irregular spellings copied from 10015992 before deleting): Diamind, Double, Header, Giermania, Madeline, New York, Orange Blossom, Pansy Blossom, Rany Day, and Reeves. Perhaps these are claim names? They are certainly not mine names. (A.B. Wilson, 12-DEC-2013)
  • Orange Blossom Shaft connects with Level 7 (see plate 18, PP-245)

Comments on the location information

  • Orange Blossom Mine labeled on topo is NOT the same as the Orange Blossom shaft shown on pl. 18 of PP-245. In fact, the coordinates given for this record may actually be the Orange Blossom shaft (pl. 18, PP-245)
