Atlantic Nickel’s Santa Rita nickel sulphide mine in Bahia, Brazil, delivered a record 12,464 t of nickel concentrate in August, with metallurgical recovery reaching 86.72%, the highest since operations restarted under Appian Capital ownership. The performance comes as the operation advances its transition from open pit to underground mining, signalling stable plant performance and effective ore blending during a complex changeover. For process and mine planners, the numbers suggest current comminution and flotation circuits are coping well with evolving underground feed characteristics.

Advanced Navigation America has opened a US manufacturing facility to scale production of its inertial navigation and robotics systems for GPS-denied underground and surface mines, reducing reliance on vulnerable, legacy GPS-based infrastructure. The plant will build mining-grade INS/IMU units and navigation systems designed to maintain centimetre-level positioning in dust, blast-induced shock and long-haul drifts where satellite signals are unavailable or intermittent. For mine operators, this supports more reliable autonomous haulage, drilling guidance and fleet tracking without installing extensive fixed beacons or repeaters.

Minera Saucito, one of Fresnillo PLC’s highest‑producing silver and gold operations in Mexico, has boosted underground productivity by replacing conventional units with two Atlas Copco XRVS 960E electric air compressors. The E-Air machines, installed deep underground, deliver compressed air via electric drives rather than diesel, cutting operating costs and reducing heat and exhaust loads in confined headings. For mine engineers, the shift supports higher air availability for drilling and bolting while easing ventilation demand and power‑supply planning.
