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 (Geology): Deposits in this small district were compared to "red bed" deposits in New Mexico and Arizona by Lindgren (1908). Copper occurs as chalcocite and copper oxides (mainly malachite) in mostly Pennsylvanian-age clastic rocks. The Cotopaxi Fault bounds the eastern margin of the block of Paleozoic sediments in this area. Proterozoic rocks are exposed east of the fault.

Comment (Geology): One known deposit, the Indian Springs Gulch prospect, is lumped into the Red Gulch district although it is in Proterozoic rocks.

Comment (Location): Approximately 9 MILES NORTH OF COTOPAXI ALONG RED GULCH"; ACCURACY ONLY TO ABOUT 0.5 MILE. ; INFO FROM LAND.ST :(1976)"

Comment (Location): This in an approximation of the center of the district. Not a mine location.

Comment (Production): LINDGREN (1908) STATES THAT TWO CARS OF HIGH GRADE ORE AND SEVERAL OF LOW GRADE ORE WERE SHIPPED IN 1907. THAT PRODUCTION WAS PRINCIPALLY FROM THE RED GULCH AND COPPER PRINCE MINES.

Comment (Workings): SHAFTS, INCLINES

Comment (Deposit): Discovery Year: LATE 1800'S
