Following the Clues
May 2019 by Ray Mills
It took me awhile before I finally got a nice mellow signal. My nugget turned out to weigh in about two dwt (pennyweight). Over the next few hours, we all picked up a few more nuggets apiece.
My intention was to end this discussion with waypoints and routes, then I found USGS maps of the Plainfield Quadrangle.
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.
With a little homework and a methodical approach to sampling, a prospector can determine if a deposit is worthy of more of an investment...
They must have assumed the paystreak was spotty and had been mined out, so they never mined as close to the side of the valley as they should have.
The big interest to prospectors thinking about the effect of erosion is not what might happen long into the future, but what they might find in the rivers later this summer when the water levels go down.
This is just the type of specimen that could have been easily ignored by the old-time miners. It felt a little heavier in my hand than a chunk of quartz of that size ought to have been.
To 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.
