Autonomous Caterpillar Haul Trucks for Rhyolite Ridge

Friday, 16 September 2022 – ioneer Ltd (ASX: INR, Nasdaq: IONR), an emerging lithium–boron
supplier, announces the completion of a Technology System Supply Agreement with Caterpillar, the
world’s largest manufacturer of construction and mining equipment. This definitive agreement builds
upon the Memorandum of Understanding signed last year and solidifies the early introduction of Cat®
MineStarTM Command for hauling, Autonomous Haul System (AHS) at ioneer’s Rhyolite Ridge LithiumBoron Project in Esmerelda County, Nevada.
Caterpillar has been a leader on the journey toward automation for many years. Fully integrated mining
automation systems offer unprecedented improvements in operator safety, equipment utilization, and
site productivity.
The results of the Rhyolite Ridge feasibility study in February 2021i
showed the viability of AHS at the
mine and the proposed application of AHS could positively impact the overall cost structure of the
operations. Cat autonomous mining trucks have safely hauled nearly 5 billion tonnes of material
worldwide, driving over 177 million kilometres (110 million miles) without a lost-time injury.
The operations are scheduled to start in 2024 with a fleet of Cat 785 next generation mining trucks
equipped with Command for hauling, and the fleet is scheduled to expand significantly in 2028. All
support equipment will feature the latest MineStarTM technology utilizing high-precision GPS and realtime analytics to maximise efficiency and accuracy in material loading.
