As a recreational Prospector Weeekends is it forMe, So the time spent prospecting is a valuble comodity. Three years in to my hunting it has been hit and miss some spots show big flakes some spots just dust and then once in a while the pickers just keep popping up.
I know I'm on the spot when I hear a Yaaa Hoo from Jane as she pans the concentrates from the sluice. So How do I Maximize my recovery ? That just depends On which spot I am working so Knowing your area and how the gold hides there is the first step and that only comes from sampling, sampling , and sampling.
Some areas such as a creek I work near Douglas City California the gold is float gold I suspect this Creek was dredged in the late 1800's so any gold has washed down and floated in a deposit about two feet deep in the area I work, this is a place where volume is the secret you just keep digging , classifing,and carrying buckets too the sluice flakes show up in every bucket. if you move 20 feet down stream there is only gold in the first 1" it washes away every year.
I also work in an area that was Hydraulicaly washed when the forest road is open and weather permits, This area is Baron of gold except what was washed out of the hill sides and accross the valley floor here is where the Quality not quanity is important the valley floor hides bed rock and the gold got caught in pockets crevises and rotten bed rock so finding how the slurry was washed accross the valley where they started and finnished is important as digging any where else pays little only small pockets of material were left behind and this is what I have had to learn to Identify at this spot its very small rounded river gravel 1/4 and less in size mixed with a dark brown sand. almost any other material there is barron. many tailing piles may hide these pockets so moving rocks some times is pay off work !
Only Through Sampling can You Decide
Quality Or Quantity
