Steel v. St. Louis Smelting and Refining…
“ Land embraced within a town-site on the public domain, when unoccupied, is not exempt from location and sale for mining purposes; its exemption is only from settlement and sale under the pre-emption laws of the United States. Some of the most valuable mines in the country are within the limits of incorporated cities, which have grown up on what was, on its first settlement, part of the public domain ”
