Did they actually verify the predictions? In my reading of the article I didn't see any core samples being made to verify the model is correct.

There wouldn't be any core for this. It would be a holdout of the brine samples used in training. The thing that would be being produced is brine, so lithium concentrations in brine samples are the validation dataset as well. In other words, this is spatial interpolation.
