ERROR TO THE CIRCUIT COURT OF THE UNITED
STATES FOR THE DISTRICT OF COLORADO
A placer patent conveys to the patentee full title to all lodes or veins within the territorial limits not then known to exist, and mere speculation and belief, based not on any discoveries in the placer tract or any tracings of a vein or lode adjacent thereto, but on the fact that quite a number of shafts sunk elsewhere in the district had disclosed horizontal deposits of a particular kind of ore which, it was argued, might be merely parts of a single vein of continuous extension through all that territory, is not the knowledge required by the law.
As the judgment in this case rests upon a sound principle of law, this Court affirms it, although it was put by the court below upon an unsound principle.
