Beartooth Pipe Preliminary Waste Rock Storage Management Plan (SRK Consulting, January 2002)
This preliminary waste rock storage management plan for BHP Billiton's Beartooth Pipe development describes geochemical testing, site characterization, and management strategies for waste rock disposal in the Panda/Koala waste rock storage area. The document concludes that approximately 99% of waste rock (biotite granite) has low reactivity, while small components of biotite schist are potentially acid-generating and will be segregated and encapsulated with non-reactive granite to ensure freezing conditions.
