My special friend.....you need to do more homework. The economics and environmental hurdles for clay deposits will never be successful.....The low concentrations and volume of water and ore to be treated will never be viable....which is why Tesla continues to lock in other supply sources. Brines are not quick to develop......or less expensive.....and are more environmentally damaging to the ecosystems and communities where they are located and are not the future flavour of battery manufacturers.
Keep clutching at new straws and jumping at shadows
