U.S. Supreme Court
Iron Silver Mining Co. v. Campbell, 135 U.S. 286 (1890)
Iron Silver Mining Co. v. Campbell
Argued March 25-26, 1890
Decided April 28, 1890
135 U.S. 286
ERROR TO THE CIRCUIT COURT OF THE UNITED
STATES FOR THE DISTRICT OF COLORADO
A lode patent, issued subsequently to the issue of a placer patent of a tract within whose metes and bounds the lode patent is located, is not conclusive evidence that the lode was so known at the time of the issue of the placer patent as to authorize the issue of the lode patent.
Where two parties have patents for the same tract of land, and the question in a judicial proceeding is as to the superiority of title under those patents, and the decision depends upon extrinsic facts not shown by the patents, it is competent to establish it by proof of those facts.
