  • Sorby Hills is Australia’s largest undeveloped, near-surface Lead-Silver-Zinc deposit in Australia. The Project comprises of granted mining leases covering six known Lead-Silver-Zinc deposits in the Kimberley Region of Western Australia, 50km northeast of Kununurra and 90km east of Wyndham Port.
  • The Project is a low risk operation located in a Tier 1 Mining Jurisdiction with an initial 10 year open cut mine plan underpinned by 92% Reserves and low cash operating cost.
  • The Definitive Feasibility Study (“DFS”) highlighted the following:-
    1. Strong pre-tax economics including A$705m net cash flow, NPV8 A$370M, IRR 35%, and average EBITDA of A$119M per annum.
    2. High-confidence study with up-to-date tendered pricing for 75% of Capital Costs
    3. 78% increase in Measured Resources and a 12% increase in Ore Reserves highlights the Project’s economic feasibility.
    4. Potential to further improve metal recoveries at Norton with additional testwork across the high grade deposit.
  • Cleaner and cheaper power will be supplied to the Project as a result of a Heads of Agreement that was executed with Horizon Power. The agreement is over a 10-year term with an option for Boab to extend. The cheaper electricity will be sourced from the Ord River hydroelectric plant to provide the majority of the energy demand of the Project and an on site diesel plant will provide 100% back-up power.
  • Boab has a Port Access Agreement with Cambridge Gulf with respect to the Wyndham Port. The Wyndham Port is the only deep-water port between Broome and Darwin. The Port Access Agreement is a critical element of the path to market for concentrates that will be produced at Sorby Hills.
