Big Easy - How high is high, How wide is wide, how deep is deep? The answer is strictly what you choose it to be.
For some ANY Gold at all is just extra - extra over the beauty of nature, the thrill of the hunt and such. For others there is a certain $ or weight that they feel is the minimum acceptable. Sometimes it's companionship, sometimes exercise, sometimes it's creating wealth with your own hands that is what is wanted.
In the beginning it is simpler to just say pan 'till you drop.
Dig down, layer by layer, layer by layer until something stops you. That could be bedrock, a layer of hard as concrete conglomerate, or a clay layer or maybe even the water level. As a beginning to the hunt just dig a hole/trench as deep as you feel is worth the effort. Lets say you go down 2 feet and find a little bit of Gold on top of a clay layer. OK, remember that. Then keep digging down layer by layer, panning a standard volume of each layer - and remember all those recovered bits of Gold and the best type of layer (write them down). Lets say you go down 3 feet to water and you find the best Gold is down 2.5 feet just under a layer of round gravel. Then go upstream a certain distance - say 20 feet. Do it all over again - paying special attention to the layer that was best before. Maybe a bit more at that level in the second hole. 20 more feet and all over again. After an hour or two or three you will see a pattern and a trend. That would be just like the panner in the Jack London story.
DO NOT final pan to just Gold in each test pan. Count the bits of Gold you see and then dump the 3/4 finish panned out concentrates into a small pail. At the end of the day of panning pan out all the day's test pan concentrates and then take the last 2 Hyper Concentrate tablespoons of Gold and black sand and bring that back to camp to finish reducing later.
Keep on going along test panning from spot to spot until the rate of Gold is being found as you want as a minimum. Tomorrow, or the day after that bring a sluice box and confirm your rate of recovery in whatever increment you like - maybe (there is that word!) so much Gold in an hour's worth of steady shoveling. A small sluice processes about 10 times the volume of a panning run - so see how that works out. Periodically take a break from running the box (and saving your concentrates all day just in a bucket) and punch another test hole 20+- feet further on. Better? Worse? Improvise, Adapt and Overcome.
At the end of the long day of sluicing (but just before your last cleanup, drag that bucket of that day's panning and sluice box concentrates over to the still running sluice box. Slowly re-run those earlier concentrates through the box again and then do a day's final cleanout.
If you had to pan out the entire day's concentrates in camp you would be a tired and hungry Cajun come midnight - BUT - re-running the day's concentrates back through the box again means that only a small amount of concentrates need to be finish panned after dinner.
laissez le bon temps rouler!
