Tailings Dam Design and Construction at Hidden Valley Mine

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 will describe the key challenges and mitigations during construction of the Hamata tailings dam at the Hidden Valley Mine.
