Extensive flooding was recorded flowing away from the open pit and into certain areas outside of the main lease area, with a portion of tailings known to have flowed around the dam into a tributary to the north of the New Alamasiwater dam.

The resulting tailings plume grew to more than 6km long with a maximum width of about 1.2 km, and an estimated a surface area of 4.7 km².
