The mineral resources comprise secondary oxide copper mineralisation that form as sub-horizontal blankets in the ferruginous saprolite horizon, immediately above underlying copper sulphide mineralisation which is structurally controlled. Oxide copper mineralisation occurs predominantly in the form of malachite, with minor amounts of azurite, chrysocolla, cuprite, and rare native copper. The primary sulphide mineralisation occurs as chalcopyrite and pyrite, with cuprite and chalcocite occurring in the transitional zone between the oxide and sulphide zones.The Anthill deposit is hosted predominantly within the Esperanza Formation. The host lithology of the orebody is inferred to be dolomitic siltstones; however, the strong weathering and oxidation process has resulted in the near complete loss of dolomite from the rock in the upper oxide zone. The mineralisation appears to be controlled by a combination of steep structural elements and broad dome features. The Anthill transition is commonly hosted in structurally controlled silicified zones as well as in silicified sedimentary breccia in dolomite, which appear to have been a preferred permeability horizon for mineralising fluids.Anthill deposit dimensionsApproximately 1,700 m x 770 m and ranges in thickness from less than 10 m to approximately 40 m; mineralisation is subdivided into three areas: Anthill East, Anthill West, and Anthill Link (low-grade).
