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.

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.

Note: the land ownership field only identifies whether the area the mine is in is generally on public lands like Forest Service or BLM land, or if it is in an area that is generally private property. It does not definitively identify property status, nor does it indicate claim status or whether an area is open to prospecting. Always respect private property.

Comments

Comment (Deposit): A white to rusty, massive, southesast trending quartz vein corps out in amphibolite schist. The vein bifurcates on the northwest and is locally characterized by boxworks. Free gold, chalcopyrite, malachite, cuprite, and chrysocolla occur on the mine dump.

Comment (Development): ACTIVE IN 1953

Comment (Identification): Sunday Morning Mine is at the mouth of Sunday Morning Creek. The site labeled "Sunday Morning Mine" on the topo is NOT the Sunday Morning Mine. It is the Sunday Morning Prospect. Do NOT confuse these two different sites with similar names. Note that Hausel's 1989 description in Bull. 68 has the names of the mines switched. Go by the Section/Township/Range.

Comment (Identification): Bull. 68, p. 150, mixes up the Mine and Prospect but is clear about which each describes because it uses sections.
