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 (Commodity): Two sample intercepts from a drill hole yielded values up to 30 oz/ton silver, 12% zinc, 5.6% lead, 3.4 % copper, and 0.029 oz/ton gold. (Sunshine files, 1987)

Comment (Development): The Pica group includes 32 unpatented claims. The Lexington adit, other prospect pits, and a 3000-ft drill hole are within the group boundary.

Comment (Geology): A base- and precious-metals anomaly indicates a possible bonanza vein target. (Sunshine files, 1987)

Comment (Location): About 15 miles WNW of Poncha Springs, just east of the Continental Divide, in secs 19-20, T 50 N, R 6 E.
