Gold
Mine life
7 years
Production
A 2022 feasibility study estimated an average annual gold production of 54,779 ounces for the first four years. The average production over the initial mine life was expected to be 55,000 ounces of gold per year. These figures are now under review following the decision to re-evaluate the project's scale.
Processing
The planned processing method is through a Carbon-In-Leach (CIL) system.
Expansion
In May 2024, Aura Minerals acquired the Pé Quente and Pezão projects, which are located near the Matupá project. The company is investing in further exploration, including 13,000 metres of drilling, to assess the potential for integrating these new areas and significantly increasing the mineral resources and reserves of a larger, consolidated Matupá project. This led to the postponement of the original construction plans to maximise the potential return on investment. The company has withdrawn its previous long-term production guidance in anticipation of a potential increase in gold reserves from the expanded project.

Workforce
The project employs 2,184 personnel, both directly and indirectly, with 68% of the workforce hired from the local community.
Production
The mine achieved commercial production in September 2025. For the fourth quarter of 2025, production totalled 15,777 gold equivalent ounces. The 2025 production guidance was between 33,000 and 40,000 ounces of gold. An updated Feasibility Study from February 2026 estimates a weighted average annual gold production of 65,000 ounces over the life of the mine.
Processing
The ore is processed at a Carbon-in-Leach (CIL) plant with a capacity of 2.0 million tonnes per annum. The process involves a three-stage crushing circuit, followed by ball milling and cyanide leaching. Gold is recovered from the solution using a ZADRA elution circuit and electrowinning, ultimately producing gold doré. The mill was operating at over 80% of its designed capacity of 4,500 tonnes per day as of September 2025, with gold recoveries consistently above 90%.
Equipment
Mining is conducted using conventional open-pit methods, employing hydraulic excavators and a fleet of haul trucks. The mining activities are primarily undertaken by a contractor.
Expansion
In February 2026, Aura Minerals announced an updated Feasibility Study for the Borborema Mine following an agreement with the Brazilian government to relocate a federal road that crosses a portion of the deposit. This agreement allowed for a significant increase in the mine's probable mineral reserves by 82% to approximately 1.5 million ounces of gold (40.7 million tonnes at 1.13 g/t Au). This update extended the mine life to 20.5 years. The company is now advancing engineering and water-access solutions to potentially increase the plant's capacity.

Bauxite
Overview
The Taralga deposit is located approximately 200 km inland from Port Kembla in New South Wales. It has a JORC-compliant resource of 38 million tonnes of gibbsite-type metallurgical bauxite. A 2012 pre-feasibility study concluded that transport by road and rail was feasible. Delays in the expansion of the Port Kembla outer harbour were previously an obstacle to the project. However, due to recent positive changes in Port Kembla logistics, the project is now considered capable of delivering bauxite into the seaborne market and is being reassessed. ABx Group is actively pursuing monetisation of the asset due to a significant increase in global bauxite prices and is in discussions with various parties regarding offtake, direct investment, or possible sale of the asset. A portion of the option fee paid by GII is anticipated to be used for project studies being conducted jointly by ABx and GII.
