ROAD TOWN, British Virgin Islands, Dec. 01, 2025 (GLOBE NEWSWIRE) — Aura Minerals Inc. (NASDAQ: AUGO and B3: AURA33) (“Aura” or the “Company”) is pleased to announce that Aura, through a wholly owned subsidiary, has completed the previously announced acquisition from AngloGold Ashanti plc (“AngloGold”) of all of the issued and outstanding securities of Mineração Serra Grande S.A. (“MSG”), owner of the Mineração Serra Grande gold mine located in Crixás, in the state of Goiás, Brazil (the “Transaction”).

Rodrigo Barbosa, President and CEO of Aura, stated: “AngloGold Ashanti has built a strong reputation for developing and operating world-class mines. MSG, located in one of Brazil’s most prominent greenstone belts, has—according to AngloGold Ashanti—produced over 3 million ounces since 1998, with a peak of 193,000 ounces in 2006, underscoring its significant potential. As a nimble company with a proven turnaround track record (e.g., Apoena and Aranzazu) and a team with deep experience, Aura is ideally positioned to unlock the mine’s full potential. Our team has a detailed plan—now under implementation—to recover production, reduce dilution, increase efficiency, and invest to expand Resources and Reserves, all executed under the highest safety and sustainability standards of our Aura 360 culture.”

Transaction Highlights:

• In consideration for the acquisition of MSG, Aura paid to AngloGold an upfront cash consideration of US$ 72.8 million on closing, on an agreed Enterprise Value of US$ 76 million, adjusted at closing for customary items as expected in the share purchase agreement signed between the parties; plus will pay deferred consideration payments equivalent to a 3% net smelter returns participation over the currently identified Mineral Resource of MSG (inclusive of the Mineral Reserve) payable quarterly.
• According to AngloGold Ashanti, in 2024, MSG produced 80 Kos of gold (2023: 86 Koz).
