Chevron’s Delo TorqForce MP has been approved by Allison Transmission as the first, and currently only, lubricant to meet the new TES 781 specification for stationary off-highway transmissions. TES 781 targets high-load, continuous-duty services such as hydraulic fracturing and high-pressure pumping, where transmissions run at sustained torque and temperature for long intervals. For mine operators using Allison-powered fixed or skid-mounted equipment, the approval provides a defined fluid option for warranty compliance and for managing wear, varnish and unplanned downtime in severe-duty drivetrains.

Evolution Mining has approved a coarse particle flotation (CPF) project at the Northparkes copper-gold mine in New South Wales, targeting higher copper recoveries by floating significantly coarser grind sizes than the existing circuit. The CPF installation will sit alongside the current concentrator, aiming to reduce overgrinding energy while capturing value from coarse sulphide particles that currently report to tailings. Board signoff of this and other portfolio projects signals continued capital allocation to brownfield process upgrades rather than major greenfield expansion.

BHP’s Western Australian Iron Ore (WAIO) haul truck fleet is delivering about 127,000 t/month (1.52 Mt/y) of additional iron ore after an engineering upgrade developed with JC Hydraulic. The solution centres on modified hydraulic tipping systems on ultra-class haul trucks, enabling faster, more reliable dump cycles and reducing truck idle time at crushers and stockpiles. For mine planners and maintenance teams, the change effectively adds high-availability truck capacity without expanding fleet size, with revenue uplift estimated in the tens of millions of dollars per year.
