Rediscovering Placerville, California Part II
March 2011 by Don RobinsonTo get to the gold, the miners had to remove the shale pieces and stack them on the sides while sluicing the remaining material through their boxes.
I had my heart set on finding a large nugget on this trip, and it seemed to me that pounding known patches was not likely to turn up a monster. Inevitably I would spend at least half my day wandering off...
I have found gold more than 200 feet above the river. It was not unusual for nuggets of an ounce or more to be found in these deposits, but fine gold and flakes are much more common.
There is a material processing principle widely used in large milling operations to improve recovery that is poorly understood by most of the micro-mining and prospecting community...
On my weekends off I spent many hours dredging the Second Broad River from Cane Creek Road up to the headwaters. I used a three-inch dredge with air and graduated to a five-inch with air.
I love it when I am in the middle of a high trash area and all the ferrous bars go away, the screen number goes to a three or an eight, and the meter is forty to a hundred. I don’t know for sure that I have found gold, but it narrows the odds down.
We split up in order to cover a larger area and found good color almost everywhere. The bedrock was shallow on both sides of the river, but the inside bend was where we concentrated our prospecting.
We just completed a trip to another river, and yes, there was definite movement and redistribution of gravels, and other prospectors have seen this as well.
