Lol, we aren't going to be mining anything. Rare earth minerals aren't rare because they're only located in isolated places, they're rare because they are only present in small amounts when mining other materials.
The hard part is the refining of rare earth minerals because it requires large investments in refineries to separate the materials and consolidate them. Infrastructure that Ukraine or America haven't invested in.
The minerals deal is just something that trump can point to as a "win" when in reality it's not worth anything. Just like everything this administration does, it's nothing but smoke and mirrors.
If peace is reached and maintained. If Russia doesn't get all of Ukraine, how long is it going to be until they invade again? No one is going to want to invest in building a mine with that hanging over it.
It’s going to take years if not decades to setup the full supply chain off that deal, he’ll likely be dead by then and China will be laughing the whole time.
Trump has zero intention of following through on any deal he makes, if he finds another option that is more beneficial to himself and himself alone, he will reneg on the deal in a microsecond.
