Rare earths – essential components in electronics, defence applications and electric vehicle batteries – are hot geopolitical items as Western countries seek to secure supplies outside of Chinese control. Exploration companies across many Canadian provinces and U.S. states are intently searching for the 17 elements, while MP Materials’ (NYSE: MP) Mountain Pass mine in California is the only producing rare earths mine in North America.
A handful of other companies whose projects have merited varying degrees of advanced economic studies are candidates for the second possible mine, though such studies don’t guarantee a mine will open. The Northern Miner takes a look at 10 projects with studies released between 2012 and 2025 that might become the next rare earths mine.
