Nev. Rev. Stat. § 517.380
In all cases in this state since July 1, 1867, where minors over the age of 18 years have sold interests acquired by them in mining claims or locations within this state, by virtue of their having located such claims, or having been located therein by others, and have executed deeds purporting to convey such interests, such deeds, if otherwise sufficient in law, shall be held valid and sufficient to convey such interest fully and completely, notwithstanding the minority of the grantor, and without any power or right of subsequent revocation. This section does not apply to cases where any fraud was practiced upon such minor, or any undue or improper advantage was taken by the purchaser or any other person to induce such minor to execute such deed.
