Remote control mining excavator specialist BuilderX, led by founder Shaolong Sui, argues that excavation—not haulage—has become the main bottleneck to further mine automation, even as autonomous haul trucks move from pilots to large fleets with clear ROI. Sui positions teleoperated and semi-autonomous excavators as the next step to unlock productivity gains where manned digging still constrains fully automated truck fleets. For mine planners and OEMs, the message is to prioritise interface standards, control latency, and operator ergonomics at the shovel face rather than only optimising haulage.

Komatsu is expanding its western US support network with a new mining parts distribution facility in Mesa, Arizona, aimed at boosting regional availability of components for large haul trucks, loaders and drills. The site will serve dealers and mine operators across key copper and gold districts in Arizona, Nevada and neighbouring states, cutting lead times for critical items that currently ship from distant hubs. Faster delivery of high-wear parts such as GET, hydraulic components and drivetrain assemblies is intended to reduce unplanned downtime and improve fleet maintenance planning.

Gold’s long-term bull case is being tied by Sprott to the late stages of a global debt cycle, with US federal debt near 120% of GDP, annual deficits around 5% of GDP and interest costs approaching US$1 trillion a year, eroding confidence in sovereign bonds. Central banks bought 244 tonnes of gold in Q1 2026 and, in cases like Turkey, sold US Treasuries while largely retaining gold via swaps, treating bullion as core collateral rather than a trading asset. Sprott argues this shift, combined with constrained mine supply, supports gold as a structural store of value even as spot prices recently slipped to about US$4,230/oz.
