Experience

Third party review of the proposed surface tailings storage facility and in-pit tailings deposition. Initial deposition was a standalone stack with the discharge point extending longitudinally along the crest of the stack. After development of mine voids, the tailings stream was diverted into the sterile mine voids.

Project reviewer for the DFS Tailings Storage Facility designed by others. Gaps in the design identified and recommendations provided for improvements to the design. Independent review of TSF construction.

Review of the life of mine (LOM) tailings storage facility strategy and preparation of report for input to the Canadian NI 43-101 Stock Exchange Report.

Review of the life of mine (LOM) tailings storage facility strategy and preparation of the PFS Report for input to the Canadian NI 43-101 Stock Exchange Report.

Advice on design concepts (start up through to closure), operation, audits, inspections, management reviews, advice on seepage, stability, tailings deposition, water recovery and preparation of tailings disposal strategy plans.

Project Manager for evaluation of valley type TSF integrated with water storage facility constructed with segregated process plant waste. Preparation of concepts (start up through to closure), evaluation reports, technical review and client liaison.

Provision of input for tailings and water balance studies for various magnetite projects (Eyre Iron – South Australia, Crosslands and Extension Hill – Western Australia); and iron ore (Roy Hill, Flinders, and FMG Nyidinghu – Western Australia). Work has involved evaluation of existing concepts (start up through to closure); development of new concepts; evaluation of tailings testwork; technical review and client liaison.

Project Manager for the Pre-Feasibility Optimisation Study for the tailings storage facility. Review and evaluation of data and development of conceptual design. Direction of design of the containment embankment evaluation reports, technical review and client liaison. Project Manager for the Tailings Storage Strategy Study for evaluation of options and selection of the “go forward option” for the Feasibility Study for thickened tailings for the first, 27 years, mine tailings storage. Review of the filtered, dry stack tailings alternative.

Project reviewer for the FS Tailings Storage Facility designed by others. Gaps in the design identified and recommendations provided for improvements to the design. Independent review of TSF construction.
