I'm not aware of a lithium mine in California. North Carolina was where most of the world's lithium was mined and refined. Pretty much all mines for lithium closed in the US because it was simply cheaper to get from either South America brine and then Australian spodumene mining. While the US stopped mining lithium however there is still a lot of lithium refinement in North Carolina. And more refinement capacity is already planned both there and other places in the US. The main reason it is in China is because China made EV and the supply chain a priority. However, most of the downstream refinement of the downstream for actual battery materials actually happens in Korea. So a lot of lithium is mined in West Australia, transported to China and then the Korea/Japan until it is shipped to Nevada where it turns into a battery. In the next few years you should see the whole supply-chain from mining to battery in the US.
