@ChrisMayLA6 @Nicovel0 @John_Loader You can also refine Lithium salts out of seawater. Lithium was the first metal element to be made in the Big Bang and in the process of star decay, which is why there is so much of it about. Lithium mines are only sporadic because there wasn’t the demand until recently. It was thrown away in mining for other minerals in greater demand. That said, I’m not sure our geology supports mining widely.
