NEWS RELEASE

AngloGold Ashanti Builds on Award-Winning Discovery, Advancing Arthur Gold Project in Nevada with first-time 4.9Moz Mineral Reserve and Robust PFS Economics

AngloGold Ashanti plc (“AngloGold Ashanti”, “AGA”, or the “Company”) is pleased to announce the Technical Report Summary for the Arthur Gold Project (“TRS”), showing a Tier One gold deposit with robust economics and strong potential for further growth in southern Nevada’s Beatty Mining District.1,2

With the completion of the pre-feasibility study, a first time Probable Mineral Reserve of 4.9Moz of contained gold (88Mt at 1.75 g/t) and 7.8Moz of contained silver (88Mt at 2.76g/t) was reported as at 31 December 2025.3 This supports an initial nine-year mine life with average annual production of approximately 500,000oz.1

At the Merlin deposit, there is also a gold Indicated Mineral Resource of 1.0Moz and gold Inferred Mineral Resource of 5.5Moz additional to the Mineral Reserve as at 31 December 2025.3,4 Silver by-product at Merlin includes an Indicated Mineral Resource of 2.0Moz and an Inferred Mineral Resource of 13.7Moz.3,4 Aggressive drilling programmes remain underway with the aim to convert additional Mineral Resource, expand the mineralised footprint and support technical studies.

“The Arthur Gold Project is a cornerstone of our strategy to build a world-class, long-life production platform in the US,” said Alberto Calderon, Chief Executive Officer of AngloGold Ashanti. “With average annual production of approximately 500,000oz in its initial phase, with some years projected to be well in excess of that, the project delivers immediate scale in a premier mining jurisdiction. This is just the beginning. With a world class orebody and a disciplined capital approach, we have a clear roadmap to growth and long-term shareholder value.”

A Tier-One Nevada Discovery with Clear Jurisdictional Advantage

The Merlin and Silicon deposits form a large-scale, continuous mineralised system within the Arthur Gold Project. Nevada consistently ranks as one of the most mining-advantaged jurisdictions globally. The project’s proximity to the cities of Las Vegas (120 miles) and Pahrump (65 miles) provides access to a well-established permitting process, a deep pool of skilled labour, professional contractors and service providers, reliable utility grid power supply, and established logistical infrastructure, advantages seldom available to large, greenfield gold-mine developments.

Robust Economics & Capital Discipline

The Arthur Gold Project is anticipated to have a structurally competitive cost profile, with all-in sustaining costs ("AISC") estimated at $954/oz.5 This resilience is underpinned by predominantly oxide mineralization (>95%) and planned conventional processing flowsheets.

The project demonstrates positive leverage at higher gold prices when compared to the price used for the Mineral Reserve at $1,950/oz:1

•At $2,715/oz gold price: Estimated after-tax NPV (5%) of c.$1.7bn

•At $3,500/oz gold price: Estimated after-tax NPV (5%) of c.$3.4bn

Operational Excellence

The development plan envisions an integrated operation comprising a 7Mtpa milling facility and a 5.5Mtpa crushed heap-leach circuit. It is anticipated that mining will utilize conventional open-pit methods with electric rope shovels and ultra-class haul trucks. To promote environmental stewardship, the project is planned to use filtered, dry-stacked tailings for enhanced water conservation.

Pathway to Production

The pre-feasibility study is expected to be presented to the AGA Board of Directors for approval to transition to the feasibility study phase in June 2026. Feasibility level environmental, hydrological and community baseline studies are currently underway.

History of an Era-Defining Gold Discovery

The discovery of the Arthur Gold Project reflects a rare convergence of history, policy and geological conviction. Beatty has a century long history of mining, but more recently, mining and exploration were halted. For decades, large areas around Beatty were effectively closed or heavily constrained due to the proposed Yucca Mountain nuclear waste repository and its planned rail corridor, limiting meaningful mineral exploration. When the federal government shelved those plans in the mid-2010s, significant tracts of prospective ground were reopened to mineral exploration.

AngloGold Ashanti moved early, applying modern geological models and systematic drilling to terrain that had seen little contemporary exploration and, with the Silicon and Merlin discoveries in 2018, delineating an entirely new gold district. Just as importantly, the Arthur Gold Project brings commercial-scale gold mining back to a region with a proud mining heritage, reconnecting a historic Nevada mining district to a new generation of long-life, high-quality production. AngloGold Ashanti’s exploration team has also been recognised with one of the mining industry’s most prestigious awards for the Silicon and Merlin discoveries—the Prospectors and Developers Association of Canada (PDAC) 2026 Thayer Lindsley Award for an international mineral discovery.

Community Commitment and Engagement

AngloGold Ashanti has invested to advance the Beatty region, establishing the Beatty Foundation, an independent nonprofit led by local stakeholders and employees. In addition, AngloGold Ashanti provides annual funding for scholarships and other community initiatives in Nye County.

These efforts align with AngloGold Ashanti’s disciplined approach to stakeholder engagement and sustainable value creation as the project advances. “Beatty has a long history rooted in mining, and we recognize that legacy carries opportunity and responsibility as we work to progress the Arthur Gold Project,” said Nick Fouche, AngloGold Ashanti’s Sr. Vice President, Nevada Projects. “Community engagement is foundational to how we operate. We are committed to listening, investing locally, and building partnerships that reflect Beatty’s values while positioning the region for long-term economic benefit.”

1 The Pre-feasibility Technical Report Summary for Arthur Gold Project is available as an exhibit to the Company’s annual report on Form 20-F, filed with the U.S. Securities Exchange Commission (“SEC”) on 26 March 2026 (“20-F”) and available for review on EDGAR at sec.gov. Estimates are as of December 31, 2025, unless otherwise noted. Economics presented herein are calculated based on the Arthur Gold Project Mineral Reserve only. This press release does not purport to be a complete summary of the TRS and is qualified in its entirety by reference to the TRS as filed with the SEC. This press release should be read in conjunction with the TRS, including the qualifications and limitations described therein, as there may be information in the TRS that may be important

2 A Tier One asset is generally defined by AngloGold Ashanti as a large, long-life, low-cost operation or project, located in a stable and supportive jurisdiction, capable of generating strong free cash flow through commodity cycles and delivering sustained value to shareholders and host countries.

3 Refer to Item 4D. Mineral Resource and Mineral Reserve in the Company’s 20-F, as well as the Company’s 2025 Mineral Resource and Mineral Reserve Report, both of which are available on the Company’s website. Rounding of numbers may result in computational discrepancies in the Mineral Resource and Mineral Reserve tabulations. See Notes on the Mineral Resource and Mineral Reserve Estimates, below.

4 Mineral Resource in this document is reported as exclusive of the Mineral Reserve before dilution and other factors are applied, unless otherwise stated. Measured and Indicated Mineral Resource is reported separately from Inferred Mineral Resource.

5 "All-in sustaining costs” is a Non-GAAP measure which is an extension of the “total cash costs” metric and incorporates all costs related to sustaining production and in particular, recognises sustaining capital expenditures associated with developing and maintaining gold mines. In addition, this metric includes the cost associated with Corporate Office structures that support these operations, the community and environmental rehabilitation costs attendant with responsible mining and any exploration and evaluation cost associated with sustaining current operations. “Total cash costs” is calculated in accordance with the guidelines of the Gold Institute industry standard and industry practice and is a Non-GAAP measure. As calculated and reported by AngloGold Ashanti, “Total cash costs” include costs for all mining, processing, onsite administration costs, royalties and production taxes, as well as contributions from by-products, but exclude amortisation of tangible, intangible and right of use assets, rehabilitation costs and other non-cash costs, retrenchment costs, corporate administration, marketing and related costs, capital costs and exploration costs.

The Company is not providing quantitative reconciliations to the most directly comparable IFRS measures for its Non-GAAP forward-looking information shown herein in reliance on the exception provided by Rule 100(a)(2) of Regulation G because the reconciliations cannot be performed without unreasonable efforts as such IFRS measures cannot be reliably estimated due to their dependence on future uncertainties and adjusting items, including, among other factors, changes in economic, social, political and market conditions, including related to inflation or international conflicts, the success of business and operating initiatives, changes in the regulatory environment and other government actions, including environmental approvals, fluctuations in gold prices and exchange rates, the outcome of pending or future litigation proceedings, and supply chain disruptions, any public health crises, pandemics or epidemics, and other business and operational risks and challenges and other factors, including mining accidents, that the Company cannot reasonably predict at this time but which may be material.

Notes on the Mineral Resource and Mineral Reserve Estimates

The Mineral Resource and Mineral Reserve stated herein were prepared in compliance with Subpart 1300 of Regulation S-K (17 CFR § 229.1300) (“Regulation S-K 1300”). Refer to Item 1300 (Definitions) of Regulation S-K for the meaning of

the terms used in AngloGold Ashanti’s Mineral Resource and Mineral Reserve reporting. The Mineral Resource and Mineral Reserve represent the amount of gold, copper, silver, sulphur and molybdenum estimated at 31 December 2025 and are based on information available at the time of estimation. Such estimates are, or will be, to a large extent, based on the prices of the respective commodities and interpretations of geologic data obtained from drill holes and other exploration techniques, which data may not necessarily be indicative of future results. The Mineral Resource and Mineral Reserve estimates are published at 31 December 2025, taking into account economic assumptions, changes to future production and capital costs, depletion, additions as well as any acquisitions or disposals during 2025. The legal tenure of each material property has been verified to the satisfaction of the accountable Qualified Person and all of the Mineral Reserve has been confirmed to be covered by the required mining permits or there exists a realistic expectation, based on applicable laws and regulations, that issuance of permits or resolution of legal issues necessary for mining and processing at a particular deposit will be accomplished in the ordinary course and in a timeframe consistent with AngloGold Ashanti’s (or its joint venture partners’) current mine plans. For the Mineral Reserve, the term “economically viable” means that profitable extraction or production has been established or analytically demonstrated in, at a minimum, a pre-feasibility study, to be economically viable under reasonable investment and market assumptions. Mineral Reserve is subdivided and reported, in order of increasing geoscientific knowledge and confidence, into Probable and Proven Mineral Reserve categories. Mineral Reserve is aggregated from the Probable and Proven Mineral Reserve categories. Ounces of gold or silver or pounds of copper or sulphur included in the Probable and Proven Mineral Reserve are estimated and reported as delivered to plant (i.e., the point where material is delivered to the processing facility) and exclude losses during metallurgical treatment. In compliance with Regulation S-K 1300, the Mineral Resource herein is reported as exclusive of the Mineral Reserve before dilution and other factors are applied, unless otherwise stated. Mineral Resource is subdivided and reported, in order of increasing geoscientific knowledge and confidence, into Inferred, Indicated and Measured Mineral Resource categories. Ounces of gold or silver or pounds of copper, sulphur or molybdenum included in the Inferred, Indicated and Measured Mineral Resource are those contained in situ prior to losses during extraction and processing. While it would be reasonable to expect that the majority of Inferred Mineral Resource would upgrade to Indicated Mineral Resource with continued exploration, due to the uncertainty of Inferred Mineral Resource, it should not be assumed that such upgrading will always occur.

If estimations must be revised due to significantly lower commodity prices, increases in operating costs, reductions in metallurgical recovery or other factors, the Mineral Resource or Mineral Reserve may not be mined or processed profitably. In addition, material write-downs of AngloGold Ashanti’s investment in its mining properties may be required, including impacts on goodwill, as well as increased amortisation, reclamation and closure charges. If AngloGold Ashanti determines that certain parts of its Mineral Resource or Mineral Reserve have become uneconomic, this may ultimately lead to a reduction in its reported aggregate Mineral Resource or Mineral Reserve, respectively. Consequently, if AngloGold Ashanti’s actual Mineral Resource and Mineral Reserve is less than current estimates, its business, prospects, results of operations and financial position may be materially impaired.

Pre-feasibility and feasibility studies for undeveloped ore bodies present estimated capital expenditure and operating costs based on anticipated tonnage and grades of ore to be mined and processed. Other factors underlying the estimations include, among others, the predicted configuration of the ore body, anticipated metal recovery rates, and estimated costs of operating and processing equipment and facilities. Actual operating and capital expenditure cost and economic returns on projects may differ significantly from original estimates. Further, it may take many years from the initial phases of exploration until commencement of production, during which time, the economic feasibility of production may change. The Mineral Resource is subject to further exploration and development, and is subject to additional risks, and no assurance can be given that they will eventually convert to Mineral Reserve.

For additional information, refer to Table 1 (Summary Mineral Resource) and Table 2 (Summary Mineral Reserve) to Paragraph (b) of Item 1303 (Summary disclosure) of Regulation S-K, which can be found on pages 27 to 35 of AngloGold Ashanti’s Earnings Release for the three months and year ended 31 December 2025. These summary tables will also be presented in AngloGold Ashanti’s annual report on Form 20-F for the financial year ended 31 December 2025 to be filed with the SEC. These summary tables include each class of Mineral Resource (Inferred, Indicated and Measured) together with total Measured and Indicated Mineral Resource, and each class of Mineral Reserve (Probable and Proven) together with total Mineral Reserve.
