Greater Duchess is a camp-scale copper-gold project southeast of Mount Isa containing Mount Hope, Trekelano, Nil Desperandum, Lady Fanny and satellite deposits. The March 2026 PFS proposed initial open pits followed by underground mines. Under the proposed Evolution acquisition, Evolution intends to process Greater Duchess ore at Ernest Henry and complete an updated Feasibility Study assessing integration with its latent processing capacity and existing infrastructure; the Glencore tolling and offtake agreements would be terminated if the scheme proceeds.
