I processed a very small sample of 150 mesh dirt from a known gold bearing area. Although I didn’t see any visible gold in the concentrates, the bottom spot plate is the result of the stannous test. I’m questioning it because the entire drop didn’t turn purple. Just a precipitate in the bottom of the droplet. Has anyone had a positive test result which looks like a precipitate?
(The top spot plate drop is from my gold bearing solution that I use to confirm my stannous is still good)
