You appear to have taken only part of the information and twisted it around to suit your own means....maybe pick up some more stock at a lower price.
Unfortunately, there are investors out there who read this type of tripe and act without proper analysis. The company have consistently posted analyses as they receive them and the heavy metal content of the sand is impressively high. One factor that you do not appear to have taken into account when discussing the percentages of the heavy metal assemblage. Obviously the greater the heavy metal content the less sand has to be processed in order to get the valuable metals. I am treating this period of share price weakness to buy more at bargain basement prices and I urge other investors who wish to make money, to do the same.
