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.

This property, which is on the Nelson and Gladiator veins, northeast of the Crown King, has been described by Lindgren as follows: “The War Eagle Gladiator is a persistent vein traceable on the surface for at least 5,000 feet and developed by shafts and tunnels. It has doubtless yielded a considerable production of gold from oxidized quartzose ore near the surface. The strike is N. 20° E. also traceable for a considerable distance and striking N. 10° E. It is exposed at the shaft 250 feet deep near the top of the ridge at an altitude of 7,000 feet and has also been opened by the Philadelphia tunnel at 800 feet from the portal. The tunnel follows this vein for 3,000 feet but without reaching ore. The same vein is also opened by an upper tunnel 280 feet above the Philadelphia adit. In these workings, however, the Nelson vein shows with a filling 2 to 5 feet thick, consisting of ankerite, with scant sulphides; it dips generally 60° to 80° W., but in places steeply east. If the Nelson vein is identical with the vein at the shaft 1,000 feet higher up on the ridge, a change has taken place in the filling, for here it shows a quartz gangue with gold and silver amounting to $20 a ton.
"Further explorations have been made to find the Gladiator vein on the tunnel level, but so far without definite result."
