Design and Construction of the Hamata Tailings Dam, Hidden Valley Mine, Papua New Guinea

December 22, 2020

The Hidden Valley Mine Tailings Storage Facility (TSF) is the first large tailings dam to be successfully constructed in Papua New Guinea (PNG). Deeply weathered tropical soils, high annual rainfall with no apparent wet or dry season, and seismically active conditions add to the complexities of tailings management in PNG. This webinar describes the key challenges and mitigations during construction of the Hamata tailings dam at the Hidden Valley Mine.
