Hawkear has said it well. My answer to such a question would normally be that such a rock will contain no visible gold, such as he implies. Chances are very low. I would ask questions like "why do I think this rock will contain gold rather than any other old rock"? "Why do I want to do all this hard yacka on this rock rather than on another rock that is more likely to contain gold"? "Why do I want to crush ANY rock up when it is much easier to pan or detect gold"?Cool thanks. So best way to find out would be crush to powder and pan it material ? Or Crush and smelt in a small crucible ?
No, I find your comments mostly well-informed and wise. If I disagree I will always say so, because I know you have the same aim of providing accurate info to others.Thanks Goldierocks, I always feel I can make a fool out of myself if I post something on geology / mineralogy before you have had a chance for a go.
Just adding to the topic, even if one were to crush and pan it, any gold that it might contain would most likely be so microscopic as to be invisible to the naked eye in a pan.
But then again FranklinDonnell I never truly learned as much from listening to what other people told me, I learned more from doing things myself.
Yeah, have a go crush it up and pan it off. Don’t die wondering.
Let us know what you find.
