What upstream means on REEx
Upstream covers everything from resource definition through mining and beneficiation, up to the point where material leaves site as ore, concentrate, or mixed rare-earth carbonate (MREC). Buyers here are typically separators, refiners, and traders securing feedstock; sellers are explorers, developers, and producers seeking offtake, financing, or technical partners.
