When I am out prospecting or detecting, I always like to bring home any rocks that look very interesting and like they might have a high content of minerals. (Possibly gold)
I bring the rocks home and put them in buckets, today I decided to break a small piece off as shown and crush it down and pan it off.
I figured I would lose any fine microscopic gold but any sign of colour would be great. Well after much patience, I got a few small specs of colour and one piece I could actually pick an move easily. I checked it under microscope just to make sure, but pretty positive it is gold due to its weight and colour.
Hopefully in the future I will get the different types crushed and process them just to see what gold I can get out of them. It is more for my own personal achievement rather than a profit making idea. That I will leave for the nuggets I find. lol
PS. There were other small bits but too hard to pick up and even harder to try get camera to focus on them. I will look at a chemical process when I do it to maximise the gold yield. If any....lol
Got my melting furnace coming anyway. Looking forward to that one.
