The only thing wildly speculative here is your attitude toward this stock and your coplete lack of understanding even after you say you have done your DD,....Based on the drill results to date (if you would read them.)they will tell you the depth and % of the holes..DO The Math...(What is huge?).what a silly question...probably over 25 million..The big guys are the many conglomerates who are interesred in buying ISM ..and of course ALL Companies of repute wait for independent results from an outside Professional Evaluator before they would invest their money!!!!!...Your comments show your blatant lack of knowledge on too many fronts to mention...have a nice day and do yourself a favour and buy some stock!!
