A lesser number of failures happened because the ore deposit was too small, even though the ore was high quality. Only those parts of the iron formation where some natural process had concentrated the iron ore to at least 50 of the total rock to be removed could be mined at a profit. About 6 of the iron-formation area met this requirement.
