You really don't know much about Skull Valley, do ya? I don't know what you're on about....the material in the various pits is what's left over from processing the ore. It is called tailings. I've never read anywhere about unprocessed ore sitting around. Are you referring to the rest of the acreage that wasn't dug up?
Spieleman and Bender, the original miners, garnered a miniscule amount of Au from the placer mine. They recovered Au at the rate of about .005 opt, which is way way below profitable levels. Doubtful that they missed enough to make reprocessing worthwhile.
You really need to read the SEC doc, and the links to the old complaint. Here's the full doc: http://www.sec.gov/litigation/complaints/comp18016.htm Any and all claims of value made by the company have been fraudulent.
