The locator of a mining claim must at the time of making his location designate his claim by posting at one (1) corner of the claim his notice of location in writing in which there shall be stated:
Before recording his notice of location, the locator must mark the boundaries of his mining claim by placing at each corner or angle of the claim a substantial monument or a post at least four (4) feet in height and four (4) inches square or in diameter. Each post and monument shall be marked with the name of the claim, the position or number of the corner or angle and the direction of the boundary lines. The locator shall mark the boundary lines so that they can be readily traced. Where it is impracticable to place a monument or post in its true position, a witness monument shall be erected and marked to indicate the true position of the corner or angle.
