I went looking for sources and found this nice article that neatly lays out the land of rare earth mineral mining: https://www.fairphone.com/en/2021/02/08/fair-mining/ https://www.fairphone.com/en/2021/02/08/fair-mining/ I've seen some videos of ASM lithium mines, stuff is nightmare inducing. The videographers spotted a handful of children in the hills trying not to be seen. I think it's doable, it'd be similar to setting up and auditing your own green coffee beans; it wouldn't be particularly capital intensive.
