In September 2026, Encore Minerals Pty Ltd reached a Final Investment Decision to develop the Windarra Tailings Project in Western Australia. Through an agreement with Maritana Minerals Limited, Encore Minerals assumed responsibility for the funding, operation, and rehabilitation of the project, which utilizes glycine leaching technology to extract gold from Windarra and Lancefield tailings.

By October 2026, Maritana Minerals secured final statutory approval for its Black Swan gold processing hub near Kalgoorlie. This included a Native Vegetation Clearing Permit, allowing for the construction of a 2.5-million-tonne-per-annum facility. Maritana has extended its early works agreement with GR Engineering Services to ensure construction momentum, aiming for initial gold production in the second half of 2027.
