Mine Info

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.

Comments

Comment (Workings): TWO ADITS, ONE 50 FEET IN LENGTH AND THE OTHER CAVED

Comment (Workings): "The site consists of an 26-ft-long silver-copper prospect adit and associated dump on the hillside above Coantag Creek. The adit is relatively stable, but its portal is partially slumped in. The site presents the normal hazards associated with abandoned underground workings." (Martin, 1994, p. 30)
