Scope and Content
The San Juan county recorder has created a separate index to affidavits showing proof of labor for mining claims. Federal mining law provides private parties the right to mine valuable mineral deposits on public land, but in order to patent a claim, the law requires the claimant to do development work. Utah law requires locators to do at least $50 worth of work within 90 days after posting the location notice, and at least $100 worth of labor annually as required by federal law. Utah law also requires an affidavit to be filed in the office of the county recorder upon completion of such work. Such affidavits show the name of the claim and where situated, the number of days' work done and the character and value of improvements, the dates labor was performed and for whose benefit, and a statement of the actual amount paid for the labor or improvements (Utah Code Annotated, 1953, 40-1-6). The San Juan County recorder's index to proof of labor affidavits provides the following information: the name of the claim, the names of locators, the names of persons whose signatures appear on the affidavit, the date filed, and the book and page number where recorded.
Alphabetically grouped by name of claim, thereunder chronological.
While the index provides summary information about labor on various mining claims, the actual affidavits are in the custody of the San Juan County recorder.
