The Woodlawn Zinc-Copper Project is a high-grade, volcanogenic massive-sulphide (VMS) deposit situated in New South Wales, Australia, located approximately 50 km northeast of Canberra and 250 km southwest of Sydney.

The Woodlawn deposit is comprised of 12 known sulphide lenses that form three mineralized horizons locally disrupted by faulting. The zinc, copper, and lead mineralization occurs as massive and stringer sulphide lenses, interpreted to have formed both on the sea floor and in coeval mudstones and volcanic breccia flows.

A positive Feasibility Study was completed in mid-2016 and in April 2024, a Production Restart Study was announced that was based on a 0.85 Mt per annum underground mine producing an average 12,000 tonnes of copper and 36,000 tonnes of zinc per annum with a 10-year mine life. The mine plan is underpinned by Underground Proven & Probably Mineral Reserves of 6.0 Mt grading 3.6% Zn, 1.5% Cu, 1.3% Pb, 29.0 g/t Ag and 0.4 g/t Au (at NSR cut-off of A$100/t).

The Mineral Reserves are based on the updated March 2024 Underground Mineral Resource estimate, which consists of:

  • Measured Resources of 1,293 kt grading 5.2% Zn, 2.1% Cu, 1.6% Pb, 47.7 g/t Ag and 0.9 g/t Au;
  • Indicated Resources of 6,833 kt grading 4.7% Zn, 1.8% Cu, 1.7% Pb, 34.6 g/t Ag and 0.4 g/t Au; and
  • Inferred Resources of 3,135 kt grading 8.5% Zn, 1.6% Cu, 1.6% Pb, 70.0 g/t Ag and 0.5 g/t Au

(at NSR cut-off of A$100/t).

Recent Activity
  • January 2025

    Develop advised that mining teams had been fully mobilized by late 2024 and refurbishment of the processing plant was 70% complete at the end of January 2025. The Woodlawn re-start plan is on time and on budget, with ore production from underground scheduled to commence in March and first concentrate production and cashflows in June 2025.

  • December 2024

    Develop’s Board of Directors made a Final Investment Decision supporting the re-start of the Woodlawn copper-zinc mine in New South Wales, Australia, after finalizing documentation for a previous announced loan facility of approximately A$100 million.

  • August 2024

    Develop has entered into an agreement for Trafigura PTE to provide US$65 million in prepayment/loan facility to bring the Woodlawn mine into production. Trafigura will buy all of Woodlawn’s production under an approximate five-year term offtake arrangement.
