First Quantum Minerals (TSX:FM) has secured a UK patent and trademark for Quantum Electra-Haul, its trolley-assist system designed to reduce diesel consumption by mine haul trucks.
The UK Intellectual Property Office granted the registrations during the northern summer of 2026. First Quantum says further patent applications covering other aspects of the technology remain pending.
Quantum Electra-Haul uses pantographs mounted on trucks to connect with overhead powerlines while travelling up mine ramps. Once connected, electric wheel motors propel the truck and its diesel engine is switched off.
First Quantum reports diesel savings of up to 90% on uphill sections when trucks are fully laden. It also estimates the system saves about two minutes for each trolley-assisted stretch, potentially reducing the number of trucks required.
The company recorded almost 500,000km of trolley-assisted haulage across its operations during 2025. More than 15km of trolley infrastructure is installed across its three largest sites.
First Quantum says its equipment has been designed to be lightweight and mobile, allowing trolley infrastructure to be relocated as mining areas change.
The company is also trialling a full-battery dump truck integrated with trolley-assist technology at the Kansanshi Copper-Gold Mine in Zambia. The trial with Hitachi Construction Machinery (TSE:6305) began in June 2024 and remains underway.
Testing is intended to assess rock haulage performance and battery charging and discharging under operating conditions.
First Quantum claims trolley assists reduced greenhouse gas emissions from its Zambian mines by 45,000 tonnes during 2025. Combined with other pit-electrification measures, estimated savings exceeded 130,000 tonnes of carbon dioxide equivalent.
First Quantum produces copper, gold, and nickel, with operating assets across Africa, Europe, and Australia.
