Identification information

Deposit ID 10017416
MRDS ID DC03449
Record type Site
Current site name Buena

Comments on the site identification

  • Unclear if the Buena Mine is the same as the Bueno Mine. The former is in the center of the W2 of Sec. 24. The latter is listed as being in the SE4 of Sec. 24 (Colorado Metal Mining Fund Board, 1960, Tungsten in Colorado, p. 18).
  • Buena Mine appears to include the Wano Group (p. 269, PP-223). Original MAS record 0080130841 (=newMRDS 10166242) for Wano Group has been deleted. It was a very minimal record.
