About the MRDS Data:
All mine locations were obtained from the USGS Mineral Resources Data System. The locations and other information in this database have not been verified for accuracy. It should be assumed that all mines are on private property.

Satelite View
MRDS mine locations are often very general, and in some cases are incorrect. Some mine remains have been covered or removed by modern industrial activity or by development of things like housing. The satellite view offers a quick glimpse as to whether the MRDS location corresponds to visible mine remains.
Mine Description
Poland (38), at the northern foot of Bigbug Mesa, is accessible by road from the Black Canyon Highway. The spur of the Santa Fe Railway that formerly served this vicinity was dismantled a few years ago. Near the southern portal, amphibolite is intruded on the north by somewhat schistose granite, and on the west by a 75-foot dike of rhyolite-porphyry. The tunnel extends northward for 1,100 feet through a ridge of this granite. It exposed several veins upon which considerable work has been done.
The Poland vein, which was cut 800 feet from the south portal, strikes northeast and dips steeply northwest. Ore on the dump shows druzy quartz with pyrite, sphalerite, and galena. According to local reports, the vein was opened by several thousand feet of drifts and a 325-foot shaft below the tunnel level. From 1900 until about 1912, intermittent production was made with a 20-stamp mill. The 1907 yield was $130,465 in gold and 16,609 ounces of silver. The total output for this period is estimated at $750,000, probably mostly in silver. According to the U. S. Mineral Resources, the mine made a small production of gold ore in 1926, 1930, and 1931. Early in 1934, occasional shipments of gold-bearing ore and concentrates were being made by F. Gibbs and associates.
Prior to 1922, some production was made from the Occidental vein which is reported to have been cut 500 feet from the north portal of the tunnel and followed to a depth of 200 feet below the tunnel level. This vein, which is said to be similar to the Poland vein, carries gold, silver, and lead.
