Any one of us who has an enginering background like myself can do it. Actually anyone who even has a background in math and geometry could calculate the volume and then the tons and thereafter with the drilling concentration report the approximate value. I just thought most people would prefer that someone like Sculpin (who has more credibility with the troops than I do) do it. I'll wait for feedback from Sculpin and then make a decision as I trust his opinion. Thanks for your post. JW
