    Aura Minerals reserve surge to 7.22Moz GEOs: project and pit notes for engineers

    First reported on MINING.com

    30 Second Briefing

    Aura Minerals has more than doubled its proven and probable reserves to 7.22 million gold-equivalent ounces (GEOs) from 3.44 million, spanning six operating mines and two development projects across the Americas. Key drivers include a 170% reserve increase at the Borborema mine in Brazil following pit expansion, updated geological models and higher gold price assumptions in a new feasibility study, plus added underground reserves at Almas and the June acquisition of the Mineração Serra Grande mine from AngloGold Ashanti. Aura drilled over 106,500 metres in 2025 on US$21.8 million of exploration spend and is targeting 600,000 GEOs/year versus 280,000 GEOs produced in 2025.

    Technical Brief

    • Exploration intensity reached over 106,500 m drilled in 2025 for US$21.8 million spend.
    • Measured and indicated resources rose 26% to 3.49 million GEOs across the portfolio.
    • Inferred resources expanded by more than 200% to approximately 3.92 million GEOs.
    • Aura now operates six producing mines plus two development assets distributed across the Americas.
    • Market capitalisation reached US$7.33 billion, with NASDAQ shares nearing the US$90.19 all‑time high.
    • Rapid reserve and resource growth at a relatively modest exploration budget suggests low discovery cost per GEO.

    Our Take

    In our database of 1208 Mining stories, relatively few gold-focused companies outside the majors report exploration budgets above US$20 million in a single year, so Aura’s US$21.8 million 2025 spend and resulting >200% inferred resource growth position it at the aggressive end of the Latin American mid-tier explorer-producer spectrum.

    Battery and electric vehicles in mining: design and power notes for engineers

    Electrification of mining fleets is advancing beyond early pilots, with battery-electric haul trucks, loaders and light vehicles moving from trial phases into multi-year deployment contracts despite recent pull-backs in some OEM roadmaps. Dan Gleeson details how mines are pairing 6–8 MWh battery trucks with on-site fast-charging bays and trolley-assist lines, and integrating underground BEVs with upgraded 11 kV substations and ventilation recalculations. Operators are reassessing mine plans, ramp gradients and power quality to manage peak loads, charger placement and heat rejection from high-capacity battery systems.

    Metso Robotic Split Strip: cathode stripping design notes for copper plant engineers

    Metso has launched the Outotec Robotic Split Strip, a compact hydraulic‑robotic system for separating copper cathode sheets from mother plates in electrorefining circuits, designed for both greenfield and brownfield plants. The unit uses robotic handling and flexible tooling to improve stripping precision and reduce sheet damage and copper waste compared with conventional mechanical strippers. For plant engineers, the modular layout and automation focus allow retrofit into existing cells with minimal footprint, supporting tighter process control and more consistent cathode quality.

    Aggreko–Harmony Eva copper hybrid plant: power and pit planning notes for engineers

    Aggreko has signed a minimum 15‑year power purchase agreement with Harmony Gold to build and operate what is described as Australia’s largest off‑grid renewable hybrid power facility for the Eva copper project in northwest Queensland. The build‑own‑operate arrangement will combine on‑site renewables with thermal generation and battery storage to supply continuous power to the remote open‑pit operation. For mine planners and process engineers, the long‑term PPA locks in a dedicated low‑emission power source, influencing pit expansion options, processing throughput and future electrification of mobile fleets.
