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 (Development): ACTIVE EXPLORATION BEGAN 1907
Comment (Commodity): NODULES OF CHALCOCITE 1 TO 2 INCHES IN DIAMETER. The pure chalcocite contains 10 oz per ton of silver (Lindgren, 1908).
Comment (Commodity): Chalcocite occurs with coal and carbonaceous shale.
Comment (Commodity): Coal also contains vanadium.
Comment (Deposit): Discovery Year: LATE 1800'S
Comment (Production): LINDGREN (1908) STATES THAT TWO CARS OF HIGH GRADE ORE AND SEVERAL CARS OF LOW GRADE ORE WERE SHIPPED IN 1907. THAT PRODUCTION WAS PRINCIPALLY FROM THE RED GULCH AND COPPER PRINCE MINES
Comment (Workings): SHAFT AT 70 DEGREES INCLINE
Comment (Geology): DEPOSITS COMPARED TO RED BED" COPPER DEPOSITS OF NEW MEXICO AND ARIZONA"
Comment (Geology): Lindgren (1908) notes the presence of coal seams that are mineralized with copper (chalcocite) mineralization. Coal seams are an inch or more in thickness. Host rocks shales and conglomerates, which dip about 70 degrees to near vertical around the shaft.
Comment (Location): Lindgren (1908) described this mine as being directly east of the creek at the settlement of Springfield, which is one-half mile north of Copperfield. Springfield is an abandoned mining settlement.
