I am not here to throw water on my own position in LAC. But I would like to know a lot more about LAC's processing method for their large deposit. A major part of their construction has to be their method of processing the so called clay material. Could they be moving the goal posts because they have not perfected their unique  process for this material? Also, they do not have a firm commitment from the locals for water, which must be a major part of handling the clay soil. Prototype processing on the kitchen table does not always scale up for high volume methods. Are they having trouble with their process??
