David Josiah Brewer,
Enterprise Mining Company v. Rico-Aspen Consol Mining Company…
“ In order to make a location, there must be a discovery; at least, that is the general rule laid down in the statute. Section 2320 provides: 'But no location of a mining claim shall be made until the discovery of the vein or lode within the limits of the claim located.' The discovery in the tunnel is like a discovery on the surface. Until one is made, there is no right to locate a claim in respect to the vein, and the time to determine where and how it shall be located arises only upon the discovery,-whether such discovery be made on the surface or in the tunnel. ”
