 For some metals, for example, cobalt, most of the mining is done in one country. But some metals are actually mined in a diversity of countries, but then the refining is concentrated in one single country. That exposes supply to various physical, geographical, or technical risks. That is why we need to put more effort to diversify, especially refining and processing these metals into useful materials. If we are to have these materials by the end of the decade, we need investment now.
