Title 30 › Chapter 2— MINERAL LANDS AND REGULATIONS IN GENERAL › § 28
Miners in each mining district can make rules, as long as those rules do not conflict with United States or state laws, about how to locate claims, how to record them, and how much work is needed to keep them. Each claim must be clearly marked on the ground so its edges can be traced. Records for claims made after May 10, 1872 must show the name(s) of the people who located the claim, the date, and a description tied to a natural object or permanent marker that identifies the claim. For claims located after May 10, 1872 that get a waiver under section 28f and until a patent is issued, at least $100 worth of work or improvements must be done each year. For claims located before May 10, 1872, $10 of work or improvements is required each year for every 100 feet along the vein until a patent is issued; if claims are held together, that work may be done on any one of them. If the work is not done, the claim can be relocated as if it had never been located, unless the original locators or their heirs resume work before that happens. If one co-owner fails to pay his share, the others who paid can give written notice or publish notice in the nearest newspaper once a week for 90 days; if the delinquent still does not pay within 90 days, his interest goes to the paying co-owners. The yearly work period for unpatented claims located since May 10, 1872 (including Alaska) begins at 12:01 a.m. on the September 1 after the claim was located. Money spent building a tunnel to develop a lode owned by the person or company counts as work on that lode, and surface work is not required in that case. The annual period that would have ended December 31, 1921 is extended to 12 o’clock meridian July 1, 1922.
