Title 30 › CHAPTER 2 — MINERAL LANDS AND REGULATIONS IN GENERAL › § 28
Miners in each mining district may make rules, as long as those rules do not conflict with U.S. law or the laws of the State or Territory, about how to locate and hold a mining claim. Each claim must be clearly marked on the ground so its boundaries can be found. Records made after May 10, 1872 must name the locators, give the date, and describe the claim by a natural object or permanent marker. For claims with a waiver under section 28f and located after May 10, 1872, at least $100 of work or improvements must be done each year until a patent issues. 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 issues. If owners share a claim, the required work may be done on any one of the shared claims. If someone fails to do the work, the claim can be relocated unless the original locators resume work before relocation. Co-owners who pay can notify a delinquent owner in writing or by publishing in the nearest newspaper once a week for 90 days; if the delinquent does not pay within 90 days, his share goes to the paying co-owners. For unpatented claims located since May 10, 1872 (including Alaska), the yearly work period starts at 12:01 a.m. on the September 1 after the claim date. Money spent running a tunnel to develop lodes owned by the tunnel owner counts as work on those lodes, whether they were located before or after May 10, 1872, and no surface work is then required. The annual period that would have ended December 31, 1921 continues until 12:00 noon on July 1, 1922.
