Panda Waste Rock Storage Area, Beartooth Bearclaw Drainage, 2000 Seepage and Waste Rock Survey Report, Ekati Diamond Mine (SRK Consulting, February 2001)
This 2000 seepage and waste rock survey report documents BHP's expanded monitoring program investigating unexpectedly low pH seepage from the Panda Waste Rock Storage Area at Ekati Diamond Mine, examining potential causes including naturally acidic precipitation, organic decomposition, waste rock breakdown, and sulphide mineral oxidation. The study found three types of seeps with varying pH levels and identified that most seeps pose low toxicity risk to aquatic organisms, though one strongly acidic seep may be affected by sulphide mineral oxidation in carbonate-depleted kimberlite.
