While true. Those are clay deposits. Nobody has yet managed to make commercial clay deposits an actual thing. So Nevada has these theoretical deposits that are large but nobody has managed to mine any. The same goes fro Clay deposits everywhere.
Here we are talking about Spodumene rocket deposit. These are typically somewhat higher grade but they have a proven track record and company with knowledge on how to commercially make lithium hydroxide or carbonade from it.
Spodumene was basically the original source for lithium, that we used to make nuclear weapon and later glass. This was for a long time almost driven out of the market by brine projects (mostly in South America) but the demand for high grade lithium hydroxide has lead to a Spodumene boom in West Australia.
