Overview |
Mount Gibson Iron mined high grade ore on the island until the seawall failure in 2014 flooded the main pit and resulted in the closure of large-scale mining operations with the subsequent loss of 300 jobs having a major impact to the local community. In April 2017, after two years of technical and financial evaluation, Mount Gibson approved re-construction of the seawall in order to resume production in the first quarter of 2019.
