Huayou in essence locked in as the DRC miner due to shareholding, as well as their relationship with Dathomir (extremely important) as well as airguide.
Tinci already has a very strong relationship with CATL, situated basically next door to them. Experienced with processing raw materials for battery production
Huayou + CATL + Tinci
(a seriously strong team, big money pool between them. This would comfortably dominate the market. A 2bn takeover is chump change for these guys considering the leg up this would provide for the next century)
vs
Huayou + BNBT +??
(BNBT chinese government relations could prove beneficial, my thoughts arent as clear with this path)
Alternatively, we could have all players in the game in the form of JV and/or offtakes, theres enough garbage for everyone
Personally, I see a takeover as a waste of money for these companies. Spending 1 or 2 billion to acquire the asset does nothing for the purchasing company. If however, a company is to purchase this, logically it will be Huayou as they dont need anyone to progress the asset. It's best to form a joint venture whereby a long-term relationship is established and monetary contributions go directly to the development of the asset.
