=1–5= Act of July 26, 1866 (14 Stat. 251): Declared the mineral lands of the public domain open to exploration and occupation by citizens of the United States or those who had declared their intentions to become citizens. It provided for claims 200 feet in length along the vein for each locator, with an additional claim for the discoverer, and an association could take up to 3000 feet in length. No width was specified, only sufficient ground for working the claim. Extralateral rights were granted inasmuch as the vein could be followed to any depth, with all its dips, angles and variations. The Act also provided for obtaining patent (fee title) from the United States. It also recognized local customs, rules and mining districts, so far as they were not in conflict with the laws of the United States.
