Thiess has set a claimed world record for a Liebherr R 9600 excavator at MACH Energy’s Mount Pleasant Operation in the Hunter Valley, moving 17 million bank cubic metres in 6,840 operating hours over 12 months. The performance equates to roughly 2,485 bank cubic metres per operating hour, signalling sustained high mechanical availability and consistent truck–shovel match on a single ultra-class hydraulic excavator. For mine planners and maintenance teams, the figures provide a real-world productivity benchmark for R 9600 fleets in large overburden and coal operations.

Genesis Minerals has lodged a binding $5.6 billion proposal to merge with Vault Minerals, which Vault’s board has deemed superior to its existing scheme with Regis Resources, setting up a contested takeover. The deal would create a $12.6 billion Australian gold producer targeting 600,000–700,000 ounces per year, anchored by Genesis’ Ulysses operation in Western Australia and Vault’s development pipeline. For engineers and planners, a combined portfolio of multiple mid-scale open pits and underground assets could reshape regional contracting, processing plant utilisation and infrastructure investment across WA goldfields.

Catalyst Metals has lifted output at the 40km Plutonic Gold Belt in Western Australia to 31,812oz in the June quarter and 104,000oz for the 2025–26 financial year, the strongest performance since 2013. Production comes from four underground and open-pit mines feeding a single central processing plant, simplifying metallurgical control and maintenance planning. The step-up in throughput and grade stability signals renewed life for a mature orogenic gold system and may justify further infill drilling, underground development and plant debottlenecking studies.
