BRAZIL

AGA Mineração - AGA Mineração, in the state of Minas Gerais, comprises the Cuiabá complex and the Córrego do Sítio mining operation as well as the Cuiabá and Queroz gold plants.

A Brief History 

Cuiabá - In 1740, artisanal miners carried out the first mining in the area. The Saint John Del Rey Mining Company Ltd acquired the mine in 1834. Exploration and development resumed in 1977, culminating with the reopening of the mine in 1985. In 1996, the company became a wholly owned subsidiary of the Anglo American Group, and in 1999, ownership was transferred to the holding company AngloGold (now AngloGold Ashanti), where it remains.

Córrego do sítio (CDS)

Gold has been intermittently mined in the Santa Barbara and Barão de Cocais region since the 19th Century. Modern exploration was undertaken across the CdS area in the 1980s by Morro Velho and São Bento Mineração.

An AngloGold Ashanti FS for the oxide Ore Reserve, to be mined by open pit and treated in a heap leach plant, was approved in 1987. The CdS open pit operations started in the 1990s, with the first phase of production between 1990 and 1998.

 

In 2002 development of underground exploration drifts began at CdS I and in 2007 the São Bento Mine was acquired from Eldorado Gold Corporation.

A feasibility study for the sulphide Ore Reserve, to be mined underground and treated in a sulphide plant, was concluded in 2010. Implementation followed and the ramp-up was concluded in 2012. In 2011, there were major renovations to the structure of the São Bento metallurgical plant that were completed in 2012.

 

In 2013, the crushing circuit was improved to optimise the throughput.

Serra Grande - Serra Grande is located in central Brazil in the state of Goiás, about 5km from the city of Crixás.

Overview and Locality

Mineração Serra Grande (MSG or Serra Grande) is wholly owned by AngloGold Ashanti and is located in the northwest of Goiás State, central Brazil.

The Serra Grande operation comprises three underground mines, namely Mina III (including orebody IV, V and Ingá), Mina Nova (including Pequizão orebody) and Mina Palmeiras. The open pits mine the outcrop of Mina III Inferior and Structure IV zones, and Pequizão. Three mining methods are used underground: sub-level stoping (bottom-up and top-down), cut and fill, and room and pillar.

One dedicated metallurgical plant, with an annual capacity of 1.5Mt, treats all ore mined.

A Brief History

Exploration began in 1973 with a phase of detailed mapping and diamond drilling, which continued until 1976. The mining operation started up in 1986 in Mina III and the metallurgical plant start-up was in 1989. Annual production peaked at 193,000oz in 2006, supported by high grades. In 2009, the metallurgical plant was expanded to 1.3Mtpa to compensate for a declining grade-profile. In 2012, AngloGold Ashanti acquired the 50% stake that belonged to the Kinross Group.
