Kindo, a public company can not be seen as spending money on anything that can reasonably be expected to go bad, if it is not normal business for them. Negotiating deals with a company that is in court or facing a law suit is not normal. If they worked a deal without the legal issues being settled, and guess wrong as to the outcome, the entire board of directors is subject to being tossed out and/or subject to a huge class action law suit.
As to your other questions, there are thousands, if not tens of thousands of mining companies, and not that many people investing in mining, certainly as compared to the last major bull market in the late 1970's. Also, LBSR remains under a black cloud for lack of substantive progress, huge dilution, shady association related to financings, and past legal issues. This history is a red flag to many.
Further, as again as compared to the late 1970's, all lot of investors are not convinced that the bull market in metals is for real, or will be lasting.
Hopefully the green flag will soon be raised for LBSR and the promise that most of here hope to see will be realized.
...still lots of risk, though. Don't bet the farm.

After word - What's the hold up on JV? Who says there is a hold up? Think! The more complicated the deal, the more parties involved, the longer it takes, especially if one party can entertain offers from outside those in the JV talks, as is the case here.
