Locators need not employ a surveyor or engineer, but should do the work and prepare the map to the best of their ability. However, locators who willfully make false material statements are guilty of a Class D felony which is punishable by imprisonment for a minimum term of 1 year and a maximum term of not more than 4 years. In addition to any penalty the Court may impose a fine of not more than $5,000 (NRS 517.300).

The map description should also state the township and range and, if possible, the section and quarter section in which the claim and the landmark are situated. It is also desirable to have the following information on the map: the type of claim (lode or placer), the date of location of the claim, the name and post office address of the locator, the county, the type of monuments used, the bearing and distance between monuments, the scale of the map, and a north arrow (true or magnetic). The claim map is a public record. The County Recorder cannot refuse to accept a map unless he or she can affirmatively show that the map does not accurately reflect the location of all the claims.

Amending a Mining Map - Please include the original map file number and the reason you are amending the map directly on the map.

Nevada law (NRS 517.215) allows the County Recorder to make changes on the county claim map to eliminate inaccuracies with unpatented claims. The County Recorder must notify the claim owners, and the claim owners must request a hearing within 30 days if they wish to contest the change.

Nevada law (NRS 517.213) requires the County Recorder to include all patented mines and mining claims on the county map and clearly distinguish them from unpatented claims. When a registered surveyor files a record of survey showing the location of a patented mine or mining claim, the County Recorder must conform the county map to the record of survey if there is any discrepancy between the two.
