Exempts property owners or assessees from notice requirements if they have an existing negotiated agreement with the mineral rights owner, lessee, agent, or operator.

Allows property owners or public utilities with recorded interests to request court injunctions against mining or extraction operations if mineral rights owners fail to comply with notice requirements.
