final height of 240 m (787 ft), it will be 1,300 m (4,265 ft) long. The dam will hold 570,000,000 metric tons (560,997,721 long tons; 628,317,447 short tons) of tailings and the mine is expected to produce 546,000,000 metric tons (537,376,764 long tons; 601,861,976 short tons). Upstream of the dam, a series of channels and embankments divert water from the Ayash River from entering the reservoir. This helps the environment and protects the stability of the dam. The reservoir is lined with a

The dam will continually be raised until it reaches 240 m (787 ft) tall at an elevation of 4,125 m (13,533 ft) and length of 1.3 km (0.8 mi). Currently the dam is undergoing its fourth raising to 215 m (705 ft) in height.

As a base for the dam, a 130 m (427 ft) concrete-face rock-fill dam was constructed. From there, the dam is being raised with rock-fill with the upstream side being protected by a concrete slab. The original starter dam was 1,050 m (3,445 ft) in length and when the dam reaches its

The dam was designed by Golder
Associates, Burnaby, B.C. and Ingetec SA between 1998 and 1999. Construction on the 130 m (427 ft) high concrete-face rock-fill starter dam began in 2000 was complete in April 2001. A 15,000,000 m (12,161 acre⋅ft) reservoir was filled behind the dam

which controls seepage of tailings into the environment. Water released into the environment is purified to meet standards and discharges from the dam are maintained at at least 150 liters per second.
