Title 30 › CHAPTER 2 — MINERAL LANDS AND REGULATIONS IN GENERAL › § 23
Mining claims made before May 10, 1872 follow whatever customs and rules were in effect when they were marked. A claim staked after May 10, 1872, whether by one person or more, may be up to 1,500 feet long along the vein, and you cannot claim ground until the vein is actually found inside that area. No claim can reach more than 300 feet on each side of the vein’s middle at the surface, and rules cannot cut that down to less than 25 feet per side unless someone else had rights on May 10, 1872 that require it. The claim’s end lines must be parallel.
