It clearly appears that buying up Frontier shares is not Mitsubishi's Lithium strategy.
As mentioned on this forum this forum, Mitsubishi is an $89-Billion market cap company.
Mits is not overly concerned about anything to do with Frontier's shares.
Mits is not going to piddle around with shares.
Mitsubishi's only interest is securing 75% of Frontier's Lithium production.
In short order, Mits has to start supplying HONDA with Lithium battery products.
To conclude, if some other entity, globally, steps in to start acquiring Frontier Lithium, that is not a key concern for Mitsubishi.
Mitsubishi already now has the Lithium supply locked up on the overall PAK development.
If Albemarle, Piedmont, Arcadium, PMET, etc.... step-in to buy up Frontier Lithium then Mitsubishi simply works with the "construction" teams of those well developed and motivated mining machines.
