Just a tip that may make your panning trips more productive. It looks like you are panning each pan all the way down in the field, at the stream. Fully processing each pan individually takes considerably more time than production panning so you are, in effect, limiting what you process/how much gold you can recover in a day. In case you are not aware of how to do production panning.....fill your pan and pan it down to less than half, add more material to that pan and repeat. You can continue to add additional material and reduce volume/concentrate it until you are in jeopardy of flushing out concentrated black sands and maybe fine particles of gold. When you reach that point empty the pan into a collection bucket. Repeat the process over and over again then process the collected concentrates* at the end of the day or take them home to pan for gold recovery in comfort.
Good luck and welcome to the prospecting side of TNET.
* I like to screen these concentrates to several mesh sizes especially the cons below 20 mesh and pan each fraction separately.
