SnapshotCarrapateena produces copper concentrate and is one of the largest mining projects in South Australia.

Ore at Carrapateena is collected from underground mine areas and processed through conventional crushing, grinding and flotation methods.

The successful commissioning and ramp up of Crusher 2 in Q3 FY2024 led to record material mined and concentrate produced.

As a part of Carrapateena Expansion, the bottom half of the Carrapateena orebody is being developed into a block cave, with the aim of unlocking the mine’s potential to be a multigenerational, low quartile cash cost producing operation.

Summary:

The Carrapateena Breccia Complex is located within the Olympic copper gold (Cu-Au) Province on the eastern edge of the Gawler Craton. It is hosted within Donington Suite granite and is unconformably overlain by approximately 480 m of Neoproterozoic sediments. Mineralisation and alteration are in the form of that seen at other large South Australian iron oxide copper gold (IOCG) deposits including Prominent Hill and Olympic Dam.

The Carrapateena copper-gold mineral deposit is hosted in a brecciated granite complex, with both bornite and chalcopyrite copper mineralisation present – the bornite being a distinct higher grade zone of mineralisation.

At deposit scale, the hematite breccia zone appears to be quite continuous, but its limits at depth are not yet well-defined. A subset of the hematite breccia zone contains significant copper mineralisation. Bornite-dominant and chalcopyrite-dominant zones appear as distinct clusters on scatter plots of copper and sulphur grades.

The mostly low-grade mineralisation in the north, east and at depth, is less continuous and has consequently been classified mainly as Inferred. Both the hematite breccia zone and the copper-mineralised zones are open at depth. The geological model is a near-vertical body of hematite dominated breccia hosted within altered granite.

The vast majority of copper and gold mineralisation within the deposit is hosted by hematite-dominated breccias with moderate mineralisation occurring within hematite altered granite breccias (Eastern Cu domain). Sulphides are the primary copper-bearing minerals in the Carrapateena Breccia Complex. Copper and gold mineralisation is structurally and chemically controlled, with subsequent alteration destroying mineralising structures. The most abundant sulphides are chalcopyrite, pyrite and bornite, and these constitute the majority of sulphides at Carrapateena. The less common sulphides are chalcocite, digenite and covellite, and in smaller amounts sphalerite and galena.

Gold mineralisation at the Carrapateena orebody is almost exclusively hosted by hematite altered breccias. Gold grains are usually very small (10 µm), and when seen in polished section, are often intimately associated with copper sulphides. Gold grains are commonly a combination of gold and minor silver (electrum).

Dimensions
The maximum extents of the Mineral Resource inside the A$25/t NSR cut-off shape are 710 m (X) x 940 m (Y) x 1,020 m (Z). The deposit geometry is generally pipe-like with the lateral extent decreasing with depth. The topographic surface over the mineralisation is at approximately 5100 RL. The depths from surface to the upper and lower limits of the Mineral Resource are approximately 480 m and 1,500 m respectively.

Commodity Production

The production for 2023 includes Estimated data for the period from January 1, 2023, to June 30, 2023. Because of the acquisition of OZL by BHP on 2 May 2023, OZL reported production only for the first quarter of 2023:
• Ore tonnes mined: 877,178 t;
• Tonnes milled: 1,079,755 t;
• Copper concentrate: 40,504 t;
• Copper metal in concentrate: 15,080 t;
• Gold metal in concentrate: 19,868 oz;
• Silver metal in concentrate: 226,751 oz.

BHP reported production for two months – May and June 2023:
• Ore tonnes mined: 880 kt;
• Tonnes milled: 856 kt;
• Copper concentrate: 30.1 kt;
• Copper payable metal: 11.7 kt;
• Payable gold concentrate: 15,304 oz;
• Payable silver concentrate: 157 koz.

Further, unlike OZL, BHP changed its financial year for future reporting to run from July 1 to June 30.
