[QUOTE="Hawkear, post: 647390, member: 4728"] Hi GoldTalk, No problem here, I have probably crushed as many specis as most. At the end of the day most of us would like to cash in as best we can and for whatever reason. I think most of us would describe our activity more in terms of the thrill of the hunt and finding of rather than in the possession of gold. Doing the SG test is just another element of that thrill. The result can be disappointing or gratifying. Just to add some further illustrations as to how the SG approximation method works, I've done the following graph of how accuracy is achieved over a number of simple approximations without the need to remember complicated formulae. As can be seen after about three approximation starting from an assumption of all quartz and no gold a very accurate (good enough) approximation of gold content can be achieved in this case 20.65gr. (Dry weight 25.68g wet 22.69g) Edit - I should have titled graph "Gold Content Progressive approximation method" [ATTACH type="full" alt="1656806958765.png"]2547[/ATTACH] [/QUOTE]
