When the committee visited the Lancaster Dam, it found an area which appeared to have been filled with slimes that had recently been mined. The dam was characterised (another word) by heavy equipment which made it possible for the acidic slimes water and fine slimes to drain into the pond and wetland below the dam. Downstream of the dam, an orange pool of settled slimes, filled with acidic mine drainage water was evident. Dry slimes were observed blowing throughout the Lancaster Dam site.
