My land is containing minerals, oils, natural gas and the government wants to take over my land. Help!

Yes. Any land or property including the territorial waters and exclusive economic zone of Nigeria containing any minerals, mineral oils and natural gas automatically belongs to the federal government of Nigeria. If initially bought by someone it must revert back to the federal government upon discovery of such mineral or gas after the expected payment of compensation for the land any improvements made on it[1]
