Shares of Chinese rare earths miners are lower Thursday on news that Tesla Inc. plans to drop use of the metals in its new generation of permanent magnet electric motors.

Shares of China Rare Earth Resources & Technology Co. are down 7.6% at the mid-day break, while shares of China Northern Rare Earth (Group) High-Tech Co. and Rising Nonferrous Metals Share Co. are down 4.1% and 8.2%, respectively.

Tesla said Wednesday at its Investor Day event that it is creating a new permanent magnet electric motor that doesn't use rare earth metals. The company added on Twitter that its new powertrain will be "more efficient."

Rare earths are used to manufacture a range of crucial technologies such as components in electric cars, smartphone touch screens and missile-defense systems. Globally, China controls most of the market for processing and refining rare earths, among some other critical minerals, according to a White House fact sheet.
