We are committed to ensuring the integrity of TSFs across our operated assets and legacy assets to protect our people, the environment and communities in which we operate.

Olympic Dam has two active upstream TSFs and a non-active upstream TSF. These TSFs have been safely managed for over 30 years. These facilities were reviewed following the failure of the Fundão Dam at Samarco and no significant deficiencies to the stability of the dams were identified.

Our approach to the design, operation and eventual closure/rehabilitation of TSF6 will be consistent with international standards and leading industry practice as represented by CDA and ANCOLD guidance.

Upstream dam designs are well suited to regions that are dry, flat and have relatively low seismic activity. Olympic Dam, approximately 575 km north-north-west of Adelaide, South Australia, is in a region where these conditions prevail. We undertook a rigorous process to determine the preferred tailings management option most applicable for the conditions at Olympic Dam. This included assessment of safety, social, and environmental considerations.

One of the purposes of these agreements is to set out detailed processes that Traditional Owners and BHP agree will be followed before any heritage site can be disturbed. [...]
