Title 30 › Chapter 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 United States or state laws, about where and how to mark and record a mining claim and how much work is needed to keep it. Each claim must be clearly marked on the ground so its borders can be found. Records made after May 10, 1872 must show the name or names of the people who located the claim, the date, and a description that uses a natural object or permanent monument to identify the claim. For claims located after May 10, 1872 that get a waiver under section 28f and until the government grants a patent, at least $100 worth of work or improvements must be done each year. For claims located before May 10, 1872, at least $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 money can be spent on any one of them. If the work is not done, the claim can be relocated as if it had never been claimed, unless the original claimants or their heirs resume work before someone new locates it. If one of several co-owners fails to pay their share, the co-owners who did the work can, after a year, give the delinquent owner a personal written notice or publish notice in the nearest newspaper once a week for ninety days. If the delinquent owner still refuses to pay after ninety days, his share goes to the co-owners who paid. For unpatented mineral claims located since May 10, 1872, including those in Alaska, the yearly work period begins at 12:01 a.m. on the September 1 after the claim was made. Money spent running a tunnel to develop a lode counts as work on that lode whether it was located before or after May 10, 1872, and the tunnel operator does not have to do surface work to hold the lode. The annual period that would have ended December 31, 1921 was extended to 12 o’clock on July 1, 1922.
