Ferreyros has delivered Peru’s 1,000th Caterpillar mining truck, a 410 short ton (372 t) payload Cat 798, to Compañía Minera Antamina for use at its copper-zinc operation at around 4,300 m elevation. The ultra-class truck will operate in high-altitude, low-oxygen conditions that challenge engine performance, tyre behaviour and haul road design, demanding close attention to cooling systems, fuel management and braking. For mine planners, the additional 372 t unit affects fleet dispatch, ramp geometry and crusher feed scheduling at one of Peru’s largest open pits.

Weir has secured an order to supply two ENDURON® high-pressure grinding rolls (HPGRs) to Zijin Mining’s Golden Ridge operation at the Akyem gold mine in Ghana, as part of a brownfield optimisation of the existing comminution circuit. The HPGRs will be integrated into a flowsheet currently based on a conventional SAG and ball mill configuration that is struggling with higher ore competency. The move signals a shift towards more energy-efficient, dry grinding technology to debottleneck throughput and cut operating costs in a mature West African gold plant.

North America’s push to meet 2027 DFARS bans on Chinese-origin rare earth magnets is colliding with mine development timelines that can exceed 30 years from discovery to production, with 30–40% of that spent on PEAs, prefeasibility, feasibility and detailed engineering. AiMinr CEO Dr Ari Rostami argues the bottleneck lies in labour‑intensive, sequential study workflows, where changes in geology, mine design or prices can force months or years of rework across geotechnical, metallurgy, hydrology and financial models. AiMinr’s cloud platform links more than 50 AI agents via a central “orchestrated engine” to run these disciplines in parallel using deterministic algorithms, aiming to compress engineering phases from decades to years or even months.
