My name is Bob and I spend my days prospecting for gold. This is a new adventure and I look forward to sharing it with you all. Treasure Net is the best gold forum I've come across so I've decided to join. As soon as I get the camera to work correctly I'll post a few images of my recent finds out here around the Randsburg area.
One of the main reasons I've joined is I'm quite perplexed by the test results on some specimens I've had tested by numerous people. The first acid test was done by an old miner that had a few years of training with a geologist friend. I watched as the 22 karat acid test ate the pyrite and left the gold.
I was not convinced because of the amount of visible gold contained in the samples, the old miner told me that the one sample the size of my thumb probably contained nearly an ounce of gold and I should get it assayed and file the claim.
I have since had the samples acid tested at pawn shops and jewelers, the guy at the pawn shop said it tests positive as gold, that's great. However, he then told me to speak to the man in the jewelry department who is an expert. I told him the specimen passed the acid test, he looked at them and said; "I disagree." So needless to say, I'm left confused.
I welcome any pointers and look forward to any replies. I'll get the images up ASAP. I added one just for the sake of adding an image but it is not clear at all.
All of the (possible gold) was inside veins of brownish pyrite. The smaller samples are from a vein that shows more mineralization such as copper and perhaps silver. The larger sample shows less mineralization but after acid bath leaves behind a 50/50 mix of gold and a very beautiful silvery metal. Following is an image of what the quartz looks like.
I guess my question is this, how accurate are these acid tests?
