Tailings storage facility
The previous mining operations at Benambra included a Tailings Storage Facility (TSF). The department rehabilitated the TSF site after the previous licensee defaulted on its obligations.
The Government and WHSP Stockman Pty Ltd (Round Oak Minerals) established an agreement for the management of an enlarged tailings storage site for the proposed Stockman project. The agreement includes provision for the post-closure monitoring and maintenance of the site.
Read more about the post-closure agreement.
Regular testing of water quality has been conducted upstream and downstream of the TSF. Results of these samples are available in the graphs for download below. Data will be updated as it becomes available.

WHSP Stockman intend to use and expand the existing TSF as part of the recommencement of mining operations, in line with the former Minister for Planning's Ministerial Assessment of the 2014 Environment Effects Statement (PDF) relating to the Stockman Project.
WHSP Stockman will be required to monitor and maintain the TSF in accordance with the relevant Australian National Committee on Large Dam (ANCOLD) standards. This requirement has been included in the approved work plan.
An Independent Technical Reviewer (ITR) panel is required to provide advice on the project, as recommended in the former Minister's Assessment of the EES.
