If you want to compare the situation at KLL in May 2020 to SO4...

If you want to compare the situation at KLL in May 2020 to SO4 now, the situation at SO4 is far worse imo with those who may bail them out being in a far higher risk position.
We know that the problems identified by KLL were almost certainly the only problems.
For example their hydro model was incorrect and they added bores. They now have salts.
Their plant was flawed. They fixed it.
Most importantly they recognized problems with their CEO and he was removed.
We still don’t know if the SO4 plant works. We don’t know if the SO4 hydro model is correct. We know they had no control over their evaporation. More importantly the CEO looks to be a risk, will he be replaced. And finally what about the risk seeking board (its hard to view them any other way)?
Had KLL gone under the loss to lenders and investors would have been a fraction of what SO4 backers face losing.
