SnapshotThe Córrego do Sítio (CdS) is a part of the AngloGold Ashanti Córrego do Sítio Mineração operations (AGA Mineração).

The mine had for a sustained period reported challenging operating results characterised by poor production and costs that remain well above the gold price. CdS was unable to either sustain itself or to fund the capital needed to ensure its long-term future and could not be crosssubsidised indefinitely by our better performing mines.

Córrego do Sítio, which consists of one open-pit mine and one underground mine, was placed on care and maintenance in August 2023.

The CdS gold deposit is located in the eastern part of the lower to middle greenschist facies of the Rio das Velhas Archaean, in the Iron Quadrangle region, on the southern margin of the São Francisco Craton in Brazil.

Deposit type
CdS is an orogenic gold deposit hosted in intensely deformed clastic, volcanoclastic, carbonaceous schists and metagreywackes in an approximately 30km northeast-southwest striking shear zone. Hydrothermal alteration phases associated with the mineralisation are dominated by sericite and carbonate.

Mineralisation style
The CdS I, II and III, gold deposits and associated targets are located in a gold trend that extends for approximately 14km in a north-easterly direction, from Grota Funda (CdS I) in the south to Anomalia (CdS III) in the north, which developed in a compressional tectonic regime. Gold is associated with quartz and fine-grained acicular arsenopyrite. The main gold targets and deposits are distributed over three trends, namely the CdS Trend and Cristina Trend hosted in metasedimentary rocks, and the Donana Trend hosted in BIF.

At CdS I, the main orebodies are Rosalino, Cachorro Bravo, Laranjeiras and Carvoaria, which constitute the current production sources and most of the Mineral Resource. At CdS II, the main orebodies are São Bento, Pinta Bem (both BIF-hosted) and Sangue de Boi (metasedimentary-hosted). At CdS III, where limited exploration has taken place, the Anomalia I orebodies are the best understood and have the highest potential, hosted in the metasedimentary and BIF sequences. The Jambeiro and Mina de Pedra targets are less drilled and less understood.

Mineralisation characteristics
The CdS deposits consist of narrow northeast to southwest elongated and folded lenses of mineralisation, parallel to the main regional deformational structure (S2), dipping 60° to 70° to the southeast and plunging 20° to 30° to the northeast. The orebodies are consistently folded, boudinaged and locally disrupted by younger structures. CdS is an orogenic type deposit comprising many hydrothermal lodes with quartz veins and low-grade sulphides, disseminated in the wall rocks. In general, the mineralisation consists of sericitic zones and quartz veinlets hosted in metapelite and BIF. The sedimentary sequence, and consequently the mineralised deposits, are cross-cut by a swarm of basic dykes of uncertain age, with a general orientation north-northeast to south-southwest dipping to the southeast, with thicknesses varying from 20cm to 20m. The gold occurs as native gold in smoky quartz veins and as microscopic or sub-microscopic inclusions in arsenopyrite (the main mineralisation style). It may also occasionally be associated with berthierite (FeSb2S4). Other typical sulphide minerals are pyrrhotite, pyrite, stibnite, sphalerite and chalcopyrite.
