3rd Party International Support - Knight Piésold
Myanmar Yang Tse Copper Limited (MYTCL) requested that Knight Piésold develop a detailed pit closure plan for the Sabetaung Pit at the S&K Copper Mine located in Myanmar following the earlier development of a preliminary pit closure plan. The S&K operation completed mining of the Sabetaung South Pit in late 2013 and the Sabetaung Pit in August 2014.
The pit will be backfilled, at least in part, with mine waste material that could include potentially acid forming (PAF) waste, as part of the pit closure plan. In order to reduce the migration of acid rock drainage (ARD) from the pit into an adjacent aquifer in the longer term, the PAF waste will need to be hydraulically isolated from the regional groundwater system. This document comprises a detailed pit closure report that will form part of the overall site closure plan.
