Mining Claim Records
Series documents actions filed with the county related to mineral interest claims. Types of actions include mineral rights and royalty assignments, mineral interest claims, lease releases, interest stipulations, corrections, bills of sale and conveyance assignments, and location notices. Information includes names of involved parties; action types and dates; and volume and page numbers. The series may also include copies of claim location notices giving descriptions and details of individual claims.
Since 1987 mining claims have also been recorded in the clerk's Microfilm [Recorded Documents] (Clerk and Recorder Official Filings). Mining claims have been indexed on computer since 1979. Also see the Surveyor's Field Notes and Plats series for recorded surveys and indexes that include some mining-related surveys.
