Code of Civil Procedure § 595.3

In actions involving the title to mining claims, or involving trespass for damage upon mining claims, if it be made to appear to the satisfaction of the court that, in order that justice may be done and the action fairly tried on its merits, it is necessary that further developments should be made, underground or upon the surface of the mining claims involved in such action, the court shall grant the postponement of the trial of the action, giving the party a reasonable time in which to prepare for trial and to do said development work.
