Geomet Exploration, Ltd. v. Lucky McUranium Corp.

Lucky McUranium (plaintiff) staked 200 mining claims covering 4,000 acres based on geologic indicators of uranium, recording notices and drilling one hole per claim but never physically occupying most of the land; Geomet (defendant), aware of Lucky's claims but believing them invalid absent actual occupancy or mineral discovery, peaceably entered and began drilling on some of the claims. Lucky sued for exclusive possession and an injunction, and the trial court found Geomet acted in bad faith and granted the relief, which the court of appeals affirmed; the Arizona Supreme Court granted review to decide whether to relax the actual-occupancy requirement.
