Comments

Comment (Commodity): The mine is noted for its large production of rich silver ore; lead and zinc are of less value, and very little copper or gold is present.

Comment (Geology): The Colorado Central vein, a fissure sulfide vein, strikes NE and dips steeply NW or is vertical; in places it splits into the North and South veins and other veins branching between the two. The veins are often bounded by granite porphyry dikes.

Comment (Location): At the mouth of Leavenworth Creek, 1-1/2 miles SSW of Georgetown, secs.19-20, T 4 S, R 74 W.

Comment (Production): Estimate total value of output exceeds $8 million.

Comment (Production): High grade Ag ore in Colorado Central Mine ranged from 200-800 opt Ag. Colorado Central vein consistently produced ore in the 200 opt Ag range for 16 years after its discovery in 1872.

Comment (Workings): The veins are accessed by several tunnels: the Aliunde, Equator, Ocean Wave, and Marshall and many shafts. Workings extend to 1050-foot level and 3/4 mile along strike of the vein.
