30 U.S.C. § 28–1 — Inclusion of certain surveys in labor requirements of mining claims; conditions and restrictions

This is one undivided provision. The word "labor," used in the third sentence of section 28 of this title, includes — without being limited to — geological, geochemical, and geophysical surveys. These surveys must be conducted by qualified experts and verified by a detailed report filed in the county office where the claim is located. That report must fully set forth four things: (a) the location of the work performed, in relation to the point of discovery and the claim's boundaries; (b) the nature, extent, and cost of the work; (c) the basic findings from the survey; and (d) the name, address, and professional background of the person or persons who did the work. There are limits: a survey may not be applied as labor for more than two consecutive years, or for more than a total of five years, on any one mining claim. Each survey must also be nonrepetitive — not a repeat — of any previous survey on that same claim.
