Vietnam plans to restart its largest rare earths mine next year

HANOI, Sept 27 (Reuters): Vietnam plans to restart its biggest rare-earths mine next year with a Western-backed project that could rival the world's largest, according to two companies involved, as part of a broader push to dent China's dominance in a sector that helps power advanced technologies.

The move would be a step toward the Southeast Asian country's aim of building up a rare-earths supply chain, including developing its capacity to refine ores into metals used in magnets for electric vehicles, smartphones and wind turbines.

As an initial step, Vietnam's government intends to launch tenders for multiple blocks of its Dong Pao mine before the year's end, said Tessa Kutscher, an executive at Australia's Blackstone Minerals Ltd, which plans to bid for at least one concession. She cited unpublished information from Vietnam's Ministry of Natural Resources and Environment, which did not respond to requests for comment.

The auction's timing could change but the government plans to restart the mine next year, said Luu Anh Tuan, chairman of Vietnam Rare Earth JSC (VTRE), the country's main refiner and Blackstone's partner in the project.

Vietnam has the second-largest rare-earth deposits, according to the U.S. Geological Survey. But they have remained largely untapped, with investment discouraged by low prices.
