There is a new gold rush, but it is for rare earth metals, not real gold. These metals include neodymium, lithium, and cobalt, which are very important for making electric cars and smartphones. More people want them because they help make cleaner technology.
Countries are investing more money to find these metals and want to depend less on China, which makes most of them. The U.S. and Europe are starting to look for these metals at home. However, there are problems, like harm to the environment and high costs. This focus on rare earth metals could change economies around the world.
