Is there documentation as to the historical thickness and chemical composition of the “salt”? Presumably, some sort of survey and assay must have been done for scientific purposes or curiosity, or prior to the commencement of “mining” to justify the investment. Wouldn’t the Utah geological records or old BLM have something on this?
Since Intrepid’s “Metal Recovery Salt” is 50% to 80% sodium chloride, it would be interesting to know how much of this has been removed and shipped. If they haven’t shipped any significant NaCl, where is this monumental stockpile of salt that came off the flats?
And, as questioned by others earlier, what is the composition of the “brine” that gets pumped? Since Intrepid evaporates the brine they collect, where does the pumped brine come from? Is there any appreciable salt in it? Or, are they just pumping what is essentially water out onto the flats so when it dissolves what is left there, it can then be re-collected and processed?
