Federal mining law, 30 U.S.C. 23, limits a lode claim to 1,500 feet along the vein and 300 feet each side of it, and says 'no location of a mining claim shall be made until the discovery of the vein or lode within the limits of the claim located'. Utah Code 40-1-1 says the same for Utah. 40-1-2 requires a monument at the place of discovery with the notice on it (claim name, locators, date, feet claimed along the vein each way, width, the general course of the vein, and a tie to a natural object or permanent monument). 40-1-3 requires the boundaries to be distinctly marked on the ground. 40-1-4 requires a substantial copy of the notice to be recorded with the county recorder within 30 days after posting: for RW 453, located September 12, 2026, by about October 12, 2026 (fld-002). 40-1-11 makes it a class B misdemeanor to tear down or deface a posted notice or remove a claim's stakes or monuments. The RW 453 notice therefore amounts to a claim that a vein or lode was discovered in Section 28; no record read says what mineral.
