Exploration AngloGold Ashanti
Exploration at AngloGold Ashanti has 2 key high level objectives to form important price and create significant value for the company:Exploration AngloGold Ashanti
1. Greenfields Exploration
Greenfields Exploration aims to make large, high-value gold discoveries leading directly to new mines. AngloGold Ashanti’s Greenfields Exploration team has been recognized as the industry’s most successful discoverer in the last fifteen years.* It has a proven track record that includes the world-class discoveries of La Colosa, Gramalote and Tropicana.These discoveries are attributed to our committed and professional team of explorationists working on a portfolio of highly prospective and strategic ground holdings. Greenfields Exploration provides a pipeline of high-quality and rigorously prioritised exploration projects, which in turn lead towards discovery of new deposits and mines.
2. Brownfields Exploration
Brownfields Exploration focuses on delivering value through incremental additions to reserves in existing mines as well as new discoveries in defined areas around existing operations. AngloGold Ashanti continues to actively drive the creation of value by growing its major asset, namely its Mineral Resource and Ore Reserve. This is based on a well-defined and effective brownfields exploration programme about existing operations, innovation in geological modelling and mine planning, and continual optimisation of its asset portfolio.
AngloGold Ashanti Mining Operations 
AngloGold Ashanti has four mining operations – both open pit and underground mining – in some regions gold mines in world :
1. AMERICAS REGION
Argentina
Cerro Vanguardia Mine
The Cerro Vanguardia Mine is a gold and silver mine located 150 km north west of Puerto San Julián, in the Santa Cruz province of Argentina., in which AngloGold Ashanti has a 92.5% stake, and is the company’s sole operation in Argentina. Fomicruz, a state company operating in the province of Santa Cruz, owns the remaining 7.5%. Located to the northwest of Puerto San Julián in the province of Santa Cruz, Cerro Vanguardia operates multiple small open pits with high stripping ratios and multiple narrow-vein underground mines. The metallurgical plant has a daily capacity of 3,000t and includes a cyanide recovery facility.
Brazil
Córrego do Sítio Mineração (AGA Mineração )
AngloGold Ashanti Córrego do Sítio Mineração (AGA Mineração ), which is wholly owned, comprises two operational complexes located in the state of Minas Gerais, close to the city of Belo Horizonte:
- The Cuiabá complex includes the Cuiabá and Lamego mines and the Cuiabá and Queiroz plant complexes. Cuiabá has been in operation for 29 years while Lamego is a more recently developed underground mine. Ore from the Cuiabá and Lamego mines is processed at the Cuiabá gold plant. The concentrate produced is transported 15km by aerial ropeway to the Queiroz plant for processing and refining. Total annual capacity of the complete Cuiabá circuit is 1.7Mt. The Queiroz hydrometallurgical plant also produces around 200,000t of sulphuric acid as a by-product, which is sold commercially on local Brazilian markets. The Cuiabá complex is changing its mining method from cut-andfill to sub-level stoping so as to increase the contribution of narrow-vein ore bodies to production (from 15% to 40%) and to improve rock engineering controls.
- The Córrego do Sítio complex comprises one surface (oxide) and two underground (sulphide) mines, as well as a heap leach pad and sulphide plant.
The Serra Grande Gold Mine is a gold mine located is located in central Brazil in the state of Goiás, about 5km from the city of Crixás. It is jointly owned by AngloGold Ashanti and Kinross Gold Corporation, who are equal partners. The mine is operated by AngloGold Ashanti but revenue is spread evenly between the two companies.. It comprises three mechanised underground mines: Mina III (the ore body IV), Mina Nova (the Pequizão ore body) and Palmeiras – and an open pit in the outcrop of the Mina III ore body. One dedicated metallurgical plant treats all ore mined. Annual plant capacity is 1.3Mt. The mine has enhanced the group’s production, Ore Reserve and Mineral Resource profiles through the 100% ownership, making a positive contribution toward AngloGold Ashanti’s near-term gold production profile in Brazil.
United States
Cripple Creek Victor mine
AngloGold Ashanti holds a 100% interest in the Cripple Creek & Victor (CC&V) Gold Mining Company’s Cresson mine, located in the state of Colorado. A surface mining operation provides oxidised ore to a crusher and valley leach facility, one of the largest in the world. Higher-grade ore with more sulphidic properties will be processed in a carbon-in-pulp (CIP) mill to achieve better recoveries. A two-phase mine-life-extension (MLE) project is well underway and is expected to increase production significantly from 2015.
Colombia La Colosa and Gramalote
Two advanced major exploration projects, La Colosa and Gramalote, are currently underway in Colombia. Extensive exploration activities are also being conducted in the region, across a reduced mineral tenement portfolio, by either AngloGold Ashanti teams or together with joint venture partners. A significant portion of the year was devoted to a third noteworthy Quebradona project area, releasing the maiden resource for Nuevo Chaquiro deposit. Refer to the section Planning for the future for further details.
2. SOUTH AFRICA
Vaal River
The Vaal River mining operations comprise three mines located around 170km to 180km from Johannesburg, near the Vaal River on the Free State-North West Province border. These three mines, which share a milling and treatment circuit, are:
Great Noligwa Mine
Great Noligwa, a mature operation nearing the end of its life, adjoins Kopanang and Moab Khotsong in the Free State. The mine primarily exploits the Vaal Reef by means of scattered mining via a twin-shaft system over three main levels at an average depth of 2,100m.
Kopanang Gold Mine
Kopanang is located to the west of neighbour Great Noligwa and bound to the south by the Jersey Fault. Gold is the primary output, with uranium oxide produced as a by-product, from a single shaft system to a depth of 2,600m. It almost exclusively exploits the Vaal Reef
Moab Khotson Mine
Moab Khotsong is AngloGold Ashanti’s newest gold mine in South Africa. Stoping operations began in November 2003 with full production achieved in 2010. Given the geological complexity of the Vaal Reef, scattered mining is employed.
West Wits
The two West Wits operations, situated southwest of Johannesburg, on the border between Gauteng and North West Province, are:
Mponeng Gold Mine
Mponeng, the world’s deepest gold mine and our flagship operation in the South Africa region, exploits the Ventersdorp Contact Reef (VCR) at depths of between 2,400m and 3,900m via a twin-shaft system. Ore is treated and smelted at the mine’s gold plant.
TauTona Mine
TauTona Mine or Western Deep Shaft, is a gold mine in South Africa. At 3.9 kilometers (2.4 mi) deep it is currently home to the world's deepest mining operations rivaled only by Mponeng gold mine TauTona exploits both the Carbon Leader Reef (CLR) and the VCR via a three-shaft system, supported by secondary and tertiary shafts sinking to depths of between 1,850m and 3,450m. TauTona’s infrastructure is to be used to access the remaining Ore Reserve at the former Savuka mine. A link between the two mines reduces dependency on a single infrastructure system, including ore passes. The integration of Savuka into TauTona has been completed and is expected to extend TauTona’s life of mine. The hoisting of Savuka ore via TauTona is planned to start in the second quarter of 2015.
3. CONTINENTAL AFRICA REGION
AngloGold Ashanti has six producing mines and processing operations – of which the group manages four – in five countries in the Continental Africa region, following much activity in 2014 with the sale of the Navachab mine in Namibia, the transition to limited mining at Obuasi in Ghana and the cessation of mining at Yatela in Mali.
Democratic Republic of the CongoKibali Gold Mine
Kibali, which began commercial production in October 2013 is steadily ramping up production. The mine is adjacent to the town of Doko and 180km from Arua on the Ugandan border. The project is co-owned by AngloGold Ashanti (45%), Randgold Resources Limited (45%) and Société Minière de Kilo-Moto (SOKIMO) (10%), a state-owned gold mining company. Randgold Resources manages and operates the mine. It is expected that Kibali will be one of the largest mines of its kind in Africa.
Ghana
Iduapriem Gold Mine
Iduapriem, which comprises the Iduapriem and Teberebie properties in a 110km² concession, is located in the Western Region of Ghana, some 70km north of the coastal city of Takoradi and 10km southwest of the Tarkwa mine. Iduapriem is an open-pit mine and its processing facilities include a carbon-in-pulp (CIP) plant.
Obuasi Mine
Obuasi Gold mine is located in the Ashanti Region, approximately 60km south of Kumasi. Mining operations have primarily been underground, to a depth of 1,500m.

Siguiri Mine
Siguiri Gold Mine is a multiple open-pit oxide gold mine in the relatively remote district of Siguiri, around 850km northeast of the country’s capital, Conakry. The area has significant potential for gold mining and has long been an area of traditional artisanal mining. The gold processing plant treats about 30,000t daily. AngloGold Ashanti holds an 85% interest in Siguiri, with the remaining 15% held in trust for the nation by the Government of Guinea.
Mali
Morila Mine
Morila Gold Mine is a joint venture between AngloGold Ashanti and Randgold Resources, which manages the mine, and in which each has a 40% interest. The Government of Mali owns the remaining 20%. Morila is situated 180km southeast of Bamako, the country’s capital. The operation ceased mining operations in 2009 and currently treats low-grade stockpiles and marginal waste. The plant, which incorporates a conventional carbon-in-leach (CIL) process with an up-front gravity section to extract the free gold, has an annual through put capacity of 4.3Mt. In 2014, 18.4Mt of material from the pit and 3.2Mt of stockpile material were processed.
Sadiola Mine
Sadiola gold mine is a joint venture between AngloGold Ashanti (41%) and IAMGOLD (41%). The Government of Mali owns the remaining 18%. The Sadiola mine is situated in south-western Mali, some 77km south-southwest of the regional capital Kayes. Mining takes place in five open-pits. On-site surface infrastructure includes a 4.9Mt per annum carbon-in-leach (CIL) gold plant where the ore is eluted and smelted.
Yatela Mine
Yatela Gold mine is situated 25km north of Sadiola. Yatela is 80% owned by the Sadiola Exploration Company Limited, a joint venture between AngloGold Ashanti and IAMGOLD, giving each a 40% stake. The balance of 20% is owned by the Government of Mali. Mining excavation activities have been suspended. Processing of the heap leach pads and ore already mined will continue until the end of 2016. Ore extraction in most of the open pits has been completed and the mine has begun closure and rehabilitation procedures.
Tanzania
Geita Mine
Geita gold mine is located in northwestern Tanzania, in the Lake Victoria goldfields of the Mwanza Region, about 120km from Mwanza and 4km west of the town of Geita Continental Africa region. And Geita Mine were one of flagship mines. The Geita gold deposit, which is currently mined as a multiple open-pit operation, has underground potential and is currently serviced by a 5.2Mt per annum carbon-in-leach (CIL) processing plant. While Geita generates its own power, the operation of its power generating facility is outsourced and fuel is delivered by road.
AUSTRALIA REGION
AngloGold Ashanti’s operations in the Australia region include, Tropicana, one of our two newest mines. Tropicana completed its first full year of production in 2014.
The two AngloGold Ashanti operations in the region are:
Sunrise Dam Mine
Sunrise dam gold mine is located 220km northeast of Kalgoorlie and 55km south of Laverton in Western Australia. Mining of the Crown Pillar at the base of the 490m deep pit was completed in early 2014. By year-end, underground mining, which is conducted by a contract mining company, was the primary source of ore. Ore is treated via conventional gravity and carbon-in-leach (CIL) processing plant which is owner-managed.
Tropicana Mine
Tropicana gold mine is located 200km east of Sunrise Dam and 330km east-northeast of Kalgoorlie. Tropicana mine is a joint venture between AngloGold Ashanti (70% and manager) and Independence Group NL (30%), First gold was poured ahead of schedule and on budget in September 2013, following development approval in November 2010. The open pit operation features a large scale, modern processing plant which uses conventional carbon-in-leach technology and includes high-pressure grinding rolls for energy-efficient comminution.
