Mine Waste Disposal in Papua New Guinea

Mine waste disposal is any waste related to mining is disposed into any environment. Environment could be land, river or deep sea or tailings dam. Waste can be either solid or slurry.

Most of the mining companies in PNG provide shallow reasons to government to allow them to dispose mine waste into river or deep sea tailing placements.
Some of these factors include but not limited to:
- Topography
- Climatic conditions.
-Geological structures with respect to seismic activities.
- Soil/rock competency etc..

The above are the factors that pose threat to the tailings dam construction, thus developers propose to dump tailings into riverine and deep sea tailings placement.

Hidden Valley mine and K92 mine have built TSF  and it is anticipated that other new mining projects could build TSF.

PNG should completely discourage riverine tailings and DSTP in PNG and encourage TSF to save PNG from mining waste management issues.
