Senior Claim
A mining claim with an earlier location date than an overlapping claim, giving it priority and control over the disputed ground.
Detailed Definition
A senior claim is a mining claim with an earlier location date than another overlapping claim. Under the "first in time, first in right" principle of mining law, the senior claim controls the disputed ground where the two claims overlap.
Key characteristics: - Earlier location date than the overlapping (junior) claim - Controls all ground within its boundaries, including overlap areas - Priority rights established by the date of valid location - Not affected by subsequently located overlapping claims
Rights of the senior claim: - Exclusive possessory rights to all ground within its boundaries - Cannot be displaced by junior claims - Controls the surface and mineral rights in overlap areas - Senior status continues as long as the claim is properly maintained
Loss of senior status: - Abandonment of the senior claim releases the overlap ground - Forfeiture for failure to pay maintenance fees - Declaration of invalidity by BLM (no valid discovery) - Void ab initio if located on withdrawn lands without VER
Claim analysis: In areas with multiple overlapping claims, identifying the senior claim is a fundamental step in mineral title examination. The senior claim's boundaries define the actual extent of rights for all claims in the overlap area.
