2024
On 19 January 2024, AngloGold Ashanti completed its initial acquisition of an 11.7 percent interest in G2 Goldfields Inc., a Canadian gold mining company with exploration properties in Guyana, South America.
On 17 October 2024, AngloGold Ashanti and IAMGOLD Corporation completed the sale of each of their 40 percent interests in Société d’Exploitation des Mines d’Or de Yatela S.A. (‘Yatela’), the company operating the Yatela gold mine, to the Government of Mali.
On 22 November 2024, AngloGold Ashanti completed its acquisition of Centamin plc, a Jersey gold mining and exploration company whose primary asset is the Sukari gold mine in Egypt.
Products
AngloGold Ashanti’s main product is gold. Once mined, the gold ore is processed into doré (unrefined gold bars) on site, and then dispatched to precious metals refineries for refining to a purity of at least 99.5 percent, in accordance with the standards of ‘good delivery’ as determined by the London Bullion Market Association (LBMA). This refined gold is then sold directly to bullion banks. By-products of its gold mining operations, often a function of local geological characteristics, include silver in Argentina and sulphuric acid in Brazil.
Operations
The company has developed a high-quality, well-diversified asset portfolio, including production from 11 operations in eight countries (Argentina, Australia, Brazil, Egypt, Ghana, Guinea, the DRC, and Tanzania), supported by greenfields projects in the United States, Colombia, and Côte d’Ivoire. It also has a focused global exploration programme. The company’s portfolio comprises long-life, operating assets with differing ore body types, located in key gold-producing regions around the world.
The company’s operations and projects are grouped regionally as follows: Africa (DRC, Egypt, Ghana, Guinea, and Tanzania, and projects in Côte d’Ivoire); Americas (Argentina and Brazil, and projects in the United States and Colombia); and Australia (Australia).
Exploration
The company’s exploration programme is focused on creating significant value for the company’s stakeholders by providing long-term optionality and improving the quality of its asset portfolio. It has a successful track record of growth through its greenfields and brownfields exploration programmes.
Brownfields exploration focuses on delivering value-accretive additions to sustain and grow its existing mines, as well as driving development of future mines at its advanced projects. AngloGold Ashanti’s discoveries include La Colosa and Quebradona (Nuevo Chaquiro) in Colombia, and Silicon-Merlin in Nevada, USA.

GHANA
AngloGold Ashanti has two mines in Ghana. Obuasi and Iduapriem are both wholly-owned and operated by AngloGold Ashanti.
Obuasi is an underground mine operating at depths of up to 1,500m, with a continuous history of mining dating back to the 1890s. Iduapriem is an open pit mine.
Obuasi is located in the Ashanti region of southern Ghana, approximately 60 km south of Kumasi. Mining was temporarily suspended at the end of 2014 while a series of economic studies progressed. Obuasi underground development resumed in the first half of 2019, with the first gold produced in December 2019. The ramp-up of the redevelopment project was delayed by the temporary stoppage of underground activities after a fall of ground incident in May 2021. Production remained suspended for several months to allow for reviews and investigations, but slowly resumed in the latter part of 2021.
Iduapriem is located in the Western region of Ghana, some 85 km from the coast and south of Obuasi, near the town of Tarkwa.
AngloGold Ashanti's rights and permits
The Obuasi mine, which is located in the Ashanti region of Ghana, originally held four contiguous mining leases, namely, the Obuasi, Binsere 1, Binsere 2, and Binsere 3 Mining Leases. The Obuasi Mining Lease was granted by the Government of Ghana on 5 March 1994, covering an area of approximately 338 km² in the Amansie East and Adansi West districts of the Ashanti region, for a term of 30 years from the date of the agreement. The Binsere Mining Leases were granted on 9 April 1998, covering an area of 140 km², for a term of 30 years from the date of the agreement. All leases in respect of the Obuasi mine had been duly ratified in accordance with Ghanaian law. In March 2007, the Government of Ghana agreed to extend the term of the Obuasi Mining Lease for a further term of 30 years. The amended Obuasi Mining Lease was also ratified by Parliament on 23 October 2008. The Obuasi Mining Lease will expire in March 2054, and the Binsere Mining Leases in April 2028. The mining leases are renewable. On 3 March 2016, the Minerals Commission approved AGA Ghana's application to surrender approximately 273.54 km² of the area to the Government of Ghana, reducing the combined area under AGA Ghana's lease areas to 201.46 km². The remaining parcel of land that will be subject to the mining lease is situated within various villages and townships in the region but excludes the municipality of Obuasi. On 15 January 2021, the Minerals Commission approved AGA Ghana's application to surrender a further 60.24 km² of lease area, thereby reducing the total lease area to 141.22 km² under three mining leases, namely, the Obuasi Mining Lease (87.48 km²), the Binsere 1 Mining Lease (29.03 km²), and the Binsere 2 Mining Lease (24.71 km²). These mining leases are covered by the Obuasi DA and Obuasi TCA.
The Iduapriem mine, which is located in the Western region of Ghana, operates under four different mining leases, namely, the Iduapriem Mining Lease (LVB1539/89) (36.47 km²), the Ajopa Mining Lease (LVB/WR326/09) (46.12 km²), the Teberebie Mining Lease (LVB3722H/92) (28.53 km²), and the Ajopa South Mining Lease (28.10 km²). On 17 February 2020, the mining leases were extended for a further period of 15 years, and such leases will now expire in February 2035. All leases in respect of the Iduapriem mine have been duly ratified in accordance with Ghanaian law.
OBUASI
The company had determined that, as of 31 December 2024, Obuasi continues to be a material property for purposes of Regulation S-K 1300.
Obuasi is wholly-owned by AngloGold Ashanti and is a production stage property. The mine is an underground operation, and it has been in operation since 1897 (more than 120 years). It has been operated by AngloGold Ashanti since 2004.
The mine is in the municipality of Obuasi, in the Ashanti region of Ghana, about 240 km northwest of the capital, Accra, and 60 km south of Kumasi. The geographic coordinates of the processing plant at Obuasi are latitude 6°10’11’N and longitude 1°41’16’W.
IDUAPRIEM
Iduapriem mine is wholly-owned and operated by AngloGold Ashanti and a production stage property. The mine is a multiple open pit operation that currently sources ore from the Block 5, Ajopa, and Blocks 7 and 8 pits. In March 2023, AngloGold Ashanti and Gold Fields announced that they had agreed to the key terms of a proposed joint venture in Ghana between Gold Fields’ Tarkwa and AngloGold Ashanti’s neighbouring Iduapriem mines. Despite constructive engagement with the government of Ghana, the requisite approvals by the government for the proposed joint venture have not yet been obtained. Following the recent national elections, Gold Fields and AngloGold Ashanti are working to engage with the new government on the potential joint venture. There can be no certainty that the parties will enter into a definitive agreement with respect to the proposed joint venture or about the timing, terms, and conditions of any such definitive agreement. Implementation of the proposed joint venture is subject to, among other matters, reaching agreement with the government of Ghana regarding the proposed joint venture, conclusion of confirmatory due diligence, and securing all requisite regulatory approvals. Consequently, the Mineral Resource and Mineral Reserve for Iduapriem are reported on the basis of a stand-alone Iduapriem mine.
The mine is located in the Western region of Ghana, some 70 km north of the coastal city of Takoradi and approximately 10 km southwest of the town of Tarkwa. The Iduapriem mine is bordered to the north by Gold Fields Ghana Limited (Tarkwa Mine) and to the east by the Ghana Manganese Company Limited (a manganese mine in existence since the 1920s).

These six individual mining concessions are consolidated into a single mining group concession No. 960.658/1987 (6,563.75 hectares).
Australia
AngloGold Ashanti operates two mines and has one project in Western Australia.
Sunrise Dam, wholly-owned by AngloGold Ashanti, is located 205 km north-northeast of Kalgoorlie and 55 km south of Laverton.
Tropicana is a joint operation between AngloGold Ashanti (70 percent and the operator) and AFB Resources Pty Limited (30 percent), a subsidiary of Regis Resources Limited. Tropicana is located 200 km east of Laverton and 330 km east-northeast of Kalgoorlie.
The Butcher Well project is a joint venture between AngloGold Ashanti (70 percent) and Northern Star Resources Limited (‘Northern Star Resources’) (30 percent). The project is managed by AngloGold Ashanti. Butcher Well is located 20 km southwest of the Sunrise Dam mine and is considered to be a potential satellite operation.
SUNRISE DAM
Sunrise Dam is a production stage property with an active underground and open pit mine that is wholly-owned and operated by AngloGold Ashanti. The company conducts brownfield exploration activities on the site.
Sunrise Dam is approximately 205 km north-northeast of Kalgoorlie and 55 km south of Laverton in the state of Western Australia.
BUTCHER WELL
Butcher Well is a joint venture between AngloGold Ashanti (70 percent) and Northern Star Resources (30 percent). Butcher Well encompasses two tenement packages, Butcher Well and Lake Carey, covering approximately 339.56 km². AngloGold Ashanti also holds a significant tenement package adjacent to the Northern Star joint venture properties.
The project is in the exploration stage in the early stages of study, with no Mineral Reserve declared. An Inferred Mineral Resource is stated, which has been the focus of a conceptual study. As the project is still in a concept study phase, no mining has taken place. Both open pit and underground mining options (using conventional open cut, drill and blast, and transverse longhole open stoping, respectively) are being explored.
The Butcher Well project is located in the Laverton district in the state of Western Australia, 20 km southwest of AngloGold Ashanti’s Sunrise Dam mine and 180 km northeast of Kalgoorlie. Butcher Well is considered a potential satellite operation to Sunrise Dam.
The Sunrise Dam airstrip is approximately 70 km by road from the project, with a travel time of approximately 90 minutes on the road on the circumference of the southern part of Lake Carey. Lake Carey is a large salt lake that covers a part of the western project area, with Sunrise Dam located to the east of the lake and the Butcher Well project located on the western shore.
TROPICANA
Tropicana mine is a production stage property. Several open pits have been developed along the strike extent of the ore body, named from north to south: Boston Shaker, Tropicana, Havana, and Havana South. Underground mines are also in operation beneath the Boston Shaker and Tropicana open pits, with a Mineral Reserve declared for the Havana underground. The project is a joint operation between AngloGold Ashanti (70 percent), as operator, and AFB Resources (Pty) Limited (30 percent), a subsidiary of Regis Resources Limited.
Tropicana is located 330 km northeast of Kalgoorlie and 200 km east of Laverton in the state of Western Australia.
AngloGold Ashanti's rights and permits
AngloGold Ashanti has been granted 21-year term mining leases with rights of renewal to all of its mining areas in Australia, including its proportionate share of joint venture operations; accordingly, it has, together with its joint venture partners where applicable, the exclusive right to mine in those areas. Both the Group and its joint venture partners are fully authorised to conduct operations in accordance with relevant laws and regulations. The mining leases and rights of renewal cover the current life-of-mine at AngloGold Ashanti's operations in Australia.
At Sunrise Dam in the state of Western Australia, one mining lease (M39/1116) covers the deposit and mine infrastructure (approximately 7,808 hectares), and another mining lease (M39/1117) covers the water extraction infrastructure used to supply the operation with water (approximately 1,768 hectares). Both leases are currently in good standing, with expiry dates in 2038. Both mining leases are within an area that is the subject of the Nyalpa Pirniku native title determination, which determination was made by the Federal Court of Australia on 31 October 2023. In relation to the area of M39/1116 and M39/1117, the native title rights and interests are non-exclusive in nature. The determination records that these mining leases prevail over native title.
The Butcher Well joint venture in the state of Western Australia has security of tenure for all current exploration licences and for the contiguous mining leases that cover its Mineral Resource. There are three mining leases: mining lease (M39/165), which covers 602.35 hectares with an expiry date in 2030; mining lease (M39/166), which covers 990 hectares with an expiry date in 2030; and mining lease (M39/230), which covers 446.4 hectares with an expiry date in 2032. These mining leases are also within the area of the Nyalpa Pirniku native title determination. In relation to the area of M39/165, M39/166, and M39/230, the native title rights and interests are non-exclusive in nature. The determination records that these mining leases prevail over native title.
At Tropicana in the state of Western Australia, the deposit is situated upon a single mining lease (M39/1096) covering approximately 27,228 hectares, which is currently in good standing, with an expiry date in 2036. This mining lease is wholly surrounded by an area that is the subject of the Nangaanya-ku Part A native title determination, which determination was made by the Federal Court of Australia on 29 November 2021, although the determination excludes M39/1096 itself. In relation to the area surrounding M39/1096, the native title rights and interests are exclusive in nature. M39/1096 itself is subject to Part B of the Nangaanya-ku native title claim, which is pending determination of the remaining issues by the Federal Court of Australia.
AngloGold Ashanti Australia Limited is also conducting early stage exploration activities in the state of Queensland under the Mineral Resources Act 1989 (QLD). AngloGold Ashanti holds 45 exploration permits covering 1,210,900 hectares. Each permit is granted with an initial term of five years, renewable for two further periods of not more than five years each.
Projects
The projects in Colombia form a significant contribution to AngloGold Ashanti’s Mineral Resource and comprise two projects: La Colosa and Minera de Cobre Quebradona (‘Quebradona’).
The projects in Nevada in the United States include North Bullfrog, Expanded Silicon, Mother Lode, and Sterling (which includes the Crown Block deposits of SNA, Secret Pass, and Daisy).
COLOMBIA
AngloGold Ashanti Colombia has two greenfields projects: La Colosa and Quebradona.
The La Colosa project is wholly-owned and managed by AngloGold Ashanti. It is located in the Department of Tolima, 150 km west of Bogotá, and 30 km west of the major town of Ibagué.
The Quebradona project is wholly-owned and managed by AngloGold Ashanti and comprises the Nuevo Chaquiro deposit, a significant copper-gold porphyry. The Quebradona project is situated in the Middle Cauca region of Colombia, in the Department of Antioquia, 90 km southwest of Medellín.
LA COLOSA
Property description: La Colosa is wholly-owned and managed by AngloGold Ashanti. La Colosa is an exploration stage project with no Mineral Reserve declared. However, open pit mining (with potentially some underground mining) is the preferred mining method. The La Colosa project is currently at an early project stage, and a number of possible technical options have been identified, all of which are capital intensive. It was placed in force majeure in 2017 through October 2024.
The project is located in the Department of Tolima, 150 km west of Bogotá, and 30 km west of the major town of Ibagué. La Colosa is a large porphyry gold deposit located on the eastern flank of the Central Cordillera of Colombia. Mineralisation is exposed on the surface.
QUEBRADONA
The Quebradona project is wholly-owned and managed by AngloGold Ashanti and comprises the Nuevo Chaquiro deposit, a significant copper-gold porphyry. The project was previously a joint venture between AngloGold Ashanti and B2Gold. It completed a conceptual study in 2016, as well as a pre-feasibility study in 2018, which supported first-time reporting of a Mineral Reserve. Quebradona will be a copper mine with gold and silver as by-products and is at a development stage.
AngloGold Ashanti became the 100 percent owner and manager of the project. B2Gold will be entitled to a royalty equal to two percent of the net profit generated from the sale of any mineral product by the project. The Quebradona project is situated in the Middle Cauca region of Colombia.
AngloGold Ashanti’s rights and permits
The La Colosa project, which is managed by AngloGold Ashanti Colombia S.A.S. (‘AGA Colombia’), is situated in the Department of Tolima in Colombia. It was placed in force majeure in 2017 due to delays in granting environmental permits by national and local environmental authorities, thereby preventing AGA Colombia from undertaking further exploration activities. The most recent one-year grant of force majeure, during which time the specified timelines for completing the various phases of the mining project under the concession contract were suspended, expired in June 2024. Although AGA Colombia applied for an extension of the grant of force majeure prior to its expiry, the Colombian Mining Authority issued a resolution on 8 April 2025 declaring that force majeure ended at La Colosa in October 2024, which is the date that AngloGold Ashanti’s application for the environmental permit for La Colosa was denied by the Colombian Ministry of Environment and Sustainable Development. The permit denial was issued on the basis of the restrictions resulting from the 2017 popular consultation in Cajamarca with respect to mining activities in the region, which basis AngloGold Ashanti has challenged as unconstitutional. Meanwhile, the underlying circumstances which led to the initial declaration of force majeure, namely that AngloGold Ashanti has not obtained an environmental permit allowing it to conduct exploration activities, persist. AngloGold Ashanti has filed a legal challenge to the denial by the Ministry of Environment and Sustainable Development of the application for the environmental permit and is evaluating its legal options with respect to the Colombian Mining Authority’s decision not to extend the force majeure declaration. In addition, AngloGold Ashanti has been conducting preparatory work and activities at La Colosa since 2017. Furthermore, AGA Colombia applied for a mining area integration (consolidation) of its concession contracts related to La Colosa, in respect of which AGA Colombia was not in compliance with some of the specified timelines. The application for mining area integration (consolidation) was approved in March 2017, which remedied the non-compliance of each consolidated concession and reset the specified timelines. La Colosa now has a single integrated mining concession contract (EIG-163), which covers a total area of 9,210 hectares and expires on 28 February 2037.
The Quebradona project, which is managed by Minera de Cobre Quebradona S.A.S. B.I.C. (‘MCQ’), is situated in the Department of Antioquia in Colombia. MCQ obtained the integration of concession agreement 5881 in October 2016 and registered it in December 2016. As a result, MCQ was granted the exclusive right to explore, take ownership, and dispose of the mineral reserves (ore) extracted from the concession area. MCQ has the right to request an extension of up to 30 years, at least two years before the expiration of the operating period. This extension is not automatic, and the request must be filed with new technical, economic, environmental, and social studies that demonstrate the status of the mineral resources. Concession contract 5881 initially covered a total area of 7,593 hectares, which was reduced to 4,881.89 hectares by the relevant mining authority (Secretaría de Minas de Antioquia) on 4 March 2022. It will expire in May 2037 and is currently in its ninth year of the integrated exploration phase. In September 2021, the permits for the construction and mining operation were approved by the relevant mining authority (Secretaría de Minas de Antioquia). On 4 November 2021, ANLA officially notified AngloGold Ashanti of its decision to ‘archive’ the environmental licence application relating to the Quebradona project. ANLA has neither denied nor granted the licence, but deemed that the information provided by AngloGold Ashanti is not enough for this authority to take a substantive decision. On 18 November 2021, AngloGold Ashanti appealed the archiving decision in order to secure further details on the specific additional information ANLA requires to make a determination. ANLA denied the appeal on 29 April 2022, and the archiving decision was confirmed. AngloGold Ashanti is in the process of preparing a new Environmental Impact Assessment for the Quebradona project, which is expected to be submitted to ANLA in 2027 in connection with its environmental licence application.
The United States of America (Nevada)
All projects in the Beatty district in southern Nevada are wholly-owned by AngloGold Ashanti. The North Bullfrog project is a development stage property, and the Expanded Silicon, Mother Lode, and Sterling projects are exploration stage properties. The North Bullfrog project and Mother Lode were acquired through the acquisition of Corvus Gold Inc. (‘Corvus Gold’) in January 2022. Sterling, which includes the Crown Block deposits of SNA, Secret Pass, and Daisy, was acquired through the acquisition of Coeur Sterling, Inc. (‘Coeur Sterling’) in November 2022.
North Bullfrog, Mother Lode, and Sterling declared Mineral Resource for the first time in 2022. The addition of the North Bullfrog project, as well as the Mother Lode and Sterling projects into the AngloGold Ashanti North America portfolio, together with the Expanded Silicon project and other exploration targets, provides the opportunity to develop a world-class operational cluster within the Beatty district in Nevada.
The North Bullfrog project is the most advanced of AngloGold Ashanti’s projects within the Beatty district. The Expanded Silicon project completed an initial assessment incorporating the Silicon and Merlin deposits during the fourth quarter of 2023, and a Mineral Resource was declared for the Merlin deposit in the Expanded Silicon project for the first time in 2023.
NORTH BULLFROG
The North Bullfrog project is a development stage property wholly-owned and managed by AngloGold Ashanti. AngloGold Ashanti acquired North Bullfrog as part of the Corvus Gold acquisition in January 2022. The proposed mining method is conventional open pit mining. A Mineral Reserve at North Bullfrog was declared for the first time in 2023.
The North Bullfrog project is located approximately 14 km northwest of the town of Beatty in Nye County, Nevada, USA. The project is within the Bullfrog Hills sub-district, of the Bullfrog Hills-Bare Mountains District. The Bullfrog Hills-Bare Mountains District is an historic mining centre that produced approximately 3 Moz of gold and 4 Moz of silver, primarily from the Barrick-owned Bullfrog pit.
EXPANDED SILICON
The Expanded Silicon project is an exploration stage property wholly-owned and managed by AngloGold Ashanti. Mineral Resource conversion drilling was a focus during 2024, which supported an updated initial assessment incorporating the Silicon and Merlin deposits. The successful completion of the project concept study in 2023 allowed the project to proceed to the next stage gate of the pre-feasibility study. The nature of the Expanded Silicon project mineralisation lends itself to conventional large scale open pit mining.
The Expanded Silicon project is located approximately 12 km east of the town of Beatty in Nye County, Nevada, USA. The project is within the Bare Mountains sub-district, of the Bullfrog Hills-Bare Mountains District.
MOTHER LODE
The Mother Lode project is an exploration stage property wholly-owned and managed by AngloGold Ashanti. A preliminary economic assessment was completed by Corvus Gold in 2020, resulting in the declaration of a Mineral Resource. AngloGold Ashanti acquired Mother Lode as part of the Corvus Gold acquisition in January 2022. The Mother Lode gold deposits contain mineralisation at or near the surface that is suitable for open pit mining methods. No Mineral Reserve has been declared at Mother Lode.
The Mother Lode project is located approximately 10 km east of the town of Beatty in Nye County, Nevada, USA. The project is within the Bare Mountains sub-district, of the Bullfrog Hills-Bare Mountains District.
STERLING
The Sterling project is wholly-owned and managed by AngloGold Ashanti. AngloGold Ashanti acquired Sterling as part of the Coeur Sterling acquisition in November 2022. Sterling includes the Sterling Mine, a mining property currently on care and maintenance. It also includes the Crown Block deposits of SNA, Secret Pass, and Daisy, and the tenements surrounding those properties, which are all in exploration stage. The elevation of the property is around 1,200 m, on the lower, eastern slopes of Bare Mountain. The local terrain is characterised by rounded or craggy ridges separated by ephemeral washes. The northern ‘Crown’ strip comprises the general area of Fluorspar Canyon.
The Sterling property is situated in southern Nye County, Nevada, near the town of Beatty, about 185 km northwest of Las Vegas. The project is within the Bare Mountains sub-district, of the Bullfrog Hills-Bare Mountains District. The Secret Pass, SNA, and Daisy deposits of the Crown Block in the Sterling project are located 6 km east of the town of Beatty. The remaining deposits of the Sterling project are located 14 km southeast of the town of Beatty.
AngloGold Ashanti’s rights and permits
In the state of Nevada, the company’s wholly-owned subsidiaries hold a significant number of mining claims on federal lands. This includes approximately 7,000 claims (covering approximately 140,000 acres) in the vicinity of Beatty, Nevada, which cover a number of different projects and deposits, including the Expanded Silicon project, the North Bullfrog project, the Mother Lode project, and the Sterling mine.
Although the Sterling mine is currently in care and maintenance status, it remains subject to complex permitting and regulatory requirements, including compliance with relevant provisions of the U.S. Federal Mine Safety and Health Act of 1977 and oversight by the U.S. Department of Labor’s Mine Safety and Health Administration (‘MSHA’).
By-Products
Several by-products are expected to be recovered as a result of processing of the gold Mineral Reserve and copper Mineral Reserve. These include 0.29 Mt of sulphur from Brazil, 17.33 Moz of silver from Argentina, 28.11 Moz of silver from Colombia, and 3.58 Moz of silver from Nevada, USA. Molybdenum, at present, is not planned for recovery at Quebradona. The Quebradona processing plant has been designed to treat underground ore and to produce copper concentrate, with provision of space in the plant site for a molybdenum plant in the future.
Seasonality
Subject to other factors and unforeseen circumstances, in the first quarter (year ended 31 December 2024), gold production is generally lower than gold production during the rest of the year as a result of the ramp-up of operations after annual holiday production declines.
Strategy
The company has key strategic focus areas, which enable it to deliver on its overall strategy.
