The groundbreaking truck features an electric driveline with an impressive 630kW (858hp) power output, accompanied by a substantial 354kWh lithium-iron phosphate (LiFePO4 or LFP) battery.

Intriguingly, this prototype battery-electric vehicle (BEV) is capable of transporting a substantial maximum payload of 65,000kg while emitting zero emissions and generating 80% less heat, potentially revolutionising underground mining operations.
Andrew Dawson, Business Line Manager for Load and Haul at Sandvik, highlighted the significant benefits of Sandvik BEVs, particularly their positive impact on operator health and safety.
"There are major benefits from Sandvik BEVs for operator health and safety thanks to reduced diesel particulates, less noise and vibration, and a reduction in heat generation," he said.

Additionally, the Sandvik TH665B is projected to operate up to 25% faster on a 1:7 ramp compared to conventional diesel trucks.
The trial of the Sandvik TH665B commenced on September 14, marking the beginning of a groundbreaking endeavor under a three-party agreement involving the mine's owner, AngloGold Ashanti, hard rock underground contract miner Barminco, and Sandvik.
One of the standout features of the Sandvik TH665B is its patented battery self-swapping system. Andrew Dawson explained, "It also allows the operator to stay in the cabin during the process, and there’s no need for major infrastructure like overhead cranes."
All parties involved in the trial share a common commitment to decarbonisation. Darren Kwok, Head of Electrification and Technology for Perenti, Barminco's ASX-listed parent company, emphasised the role of BEVs like the Sandvik TH665B in the future of electric mining and decarbonisation.
"Battery-electric vehicles (BEVs) not only have the potential to lower carbon emissions, they can also improve the underground environment for mine workers and boost the efficiency of operations,” he said.
Sustainability has quickly become a central pillar of the gold industry, reflecting a commitment to responsible resource extraction and the preservation of natural ecosystems for future generations.
This landmark trial at the Sunrise Dam gold mine represents a significant step forward in sustainable mining practices, offering a cleaner, safer, and more efficient future for the industry.
