4.1.1 Iron Ore Mining There are two basic methods of mining iron ore. These are: • Surface mining or open-pit mining • Underground or shaft mining To be competitive, iron mining must be done on a very large scale. Surface mining is the preferred choice, although there are exceptions. Small, low-capacity mines have rapidly disappeared.

The stratigraphy and deposits revealed during the excavations demonstrate that the mining activities used in the past to extract iron ore at MMA 1 were not indicative of shaft mining. Rather, the spoil from relatively shallow ancient digging events was piled up around the newly created depressions that they made, producing traps of varying ...
